Description

[0001] The present invention relates to a self-propelled soil tillage machine with a hull soil tillage machine, the hull soil tillage machine comprising: a machine frame, a travel drive as a first consumer of the soil tillage machine, a chassis with a plurality of running gears which can roll on a ground and which supports the machine frame standing on the ground, wherein at least one running gear is drivable by the travel drive, a working device as a second consumer of the soil tillage machine, wherein the working device has a working tool designed for soil tillage, an operating station as a workplace of a machine operator operating the soil tillage machine, and a control device for controlling operation of the soil tillage machine.

[0002] The body soil tillage machine and in particular the machine frame thereof are designed to accommodate a power arrangement as a power source of the soil tillage machine, wherein the power arrangement comprises a power device which is designed to provide working energy for operation of at least one of the consumers of the soil tillage machine.

[0003] Such a soil tillage machine is generally known, for example from DE 10 2021 129 619 A1 or DE 10 2014 011 195 A1. As in the case of DE 10 2021 129 619 A1, the present application also preferably envisages a road milling machine, a stabilizer, a recycler, or a surface miner as the self-propelled soil tillage machine. The working tool is therefore preferably a rotating working tool designed to remove material from the soil, in particular a milling drum with a plurality of milling cutters mounted on the outside of a milling drum tube, preferably in a helical arrangement.

[0004] Currently, self-propelled soil tillage machines, such as road milling machines, stabilizers, recyclers and surface miners, are constructed from their individual parts, whereby individual functional units, such as an internal combustion engine as the central power source of the soil tillage machine, a drive with a rotating caterpillar, the working equipment and / or the working tool, and the like, are attached as pre-assembled assemblies to the self-propelled soil tillage machine created during assembly.

[0005] Different ancillary requirements placed on the tillage machine beyond direct tillage, for example, with regard to noise emissions, dirt emissions in different areas of application, particularly due to different legislation, different availability of energy quantities and / or energy forms, and different technical constraints for the respective application, may no longer be met to the desired quality by a single tillage machine. Manufacturers of self-propelled tillage machines are therefore faced with the increasingly demanding challenge of providing a tillage machine that is as suitable as possible for a specific application.

[0006] This provision of soil tillage machines that are appropriately equipped for a given processing spectrum but are constructed differently to meet the processing spectrum while taking existing additional requirements into account will, without further measures, result in considerable additional costs, at least in assembly, and will subsequently probably also result in increased space requirements for assembly, since without further measures it cannot be expected that soil tillage machines that are conceptually different in terms of their energy conversion and / or energy transmission can be easily assembled at one and the same assembly location.

[0007] It is therefore an object of the present invention to reduce the cost of providing soil tillage machines which are suitable for performing one and the same soil tillage spectrum but which differ conceptually with regard to the energy conversion and / or energy transmission always required on a soil tillage machine, and to enable an economical diversification of the product range of soil tillage machines for one and the same tillage spectrum.

[0008] Today, manufacturers of tillage machines already offer different tillage machines for a similar tillage spectrum based on the same physical operating principle. However, these tillage machines differ primarily in their performance limits, i.e., essentially in the dimensions of their working equipment, in particular their working tools, and consequently in the power consumption of the working equipment. Thus, different tillage machines are offered for different working widths and / or different working capacities, which in turn can be equipped with different working tools for similar tillage operations based on the same physical operating principle, in particular soil removal, but with different working results.

[0009] In the particularly preferred case of abrasive soil cultivation, different removal widths can be achieved using soil cultivation machines with different widths of working tools. Different removal priorities, such as the greatest possible removal rate versus the finest possible soil surface, can be achieved using working tools with different removal devices in terms of design, number, and / or arrangement, such as milling chisels.

[0010] The range of work that can be performed by a soil tillage machine results from the totality of the working tools that can be attached to one and the same base unit. The base unit is essentially determined by its machine frame, which sets limits for the work equipment and / or working tools that can be attached to it. In the technical field of soil-removing milling machines, which is of particular interest here, various milling tools can be attached to one and the same base unit. These tools differ in their respective milling widths, which can be selected within a predetermined milling width range, and / or which can differ in the number and / or shape of the milling chisels attached to them.

[0011] Regardless of the range of different working devices and working tools available for a given soil tillage machine, the rest of the soil tillage machine, i.e. the basic unit, generally remains unchanged due to the selection of components in the area of ​​its working devices.

[0012] The present invention is therefore not based on the question of how one and the same soil tillage machine can be used for different tillage tasks, but rather how one and the same soil tillage machine can best fulfill one and the same soil tillage task under different legal and / or technical and / or economic constraints. This, of course, does not preclude a change of working equipment and / or working tool on a soil tillage machine according to the invention. However, such a change is not necessary for solving the problem defined above.

[0013] This object is achieved according to the invention in that the soil tillage machine is constructed in a modular manner with regard to its power arrangement as its power source.

[0014] This makes it possible to select a force arrangement that is particularly suitable for the later application from a number of different, fundamentally possible force arrangements and to install it on the soil tillage machine when planning the soil tillage machine.

[0015] To realize the modular design with regard to the power arrangement, the hull tillage machine includes: a first bearing interface for the preferably intended detachable, physical connection of the power arrangement to the machine frame, a first signal interface for establishing a preferably intended detachable, signal-transmitting first signal connection between the control device and the power arrangement, and at least one working energy interface for establishing a preferably intended detachable, working energy-transmitting working energy connection between the at least one consumer and the power arrangement.

[0016] Through the interfaces mentioned, the power arrangement can be connected to the trunk soil tillage machine mechanically through the first bearing interface, in terms of signal and data transmission through the first signal interface, and for the transmission of working energy to the at least one consumer through the working energy interface.

[0017] The connection of an arrangement mentioned in the present invention, such as the power arrangement above, to the body soil cultivating machine ultimately means a direct or indirect connection of the components to the machine frame.

[0018] The first bearing interface can have a plurality of mechanical coupling and / or fastening means. Possible coupling means can be, for example, bearing recesses or bearing projections. Possible fastening means can be connecting means, such as at least one fastening opening with a form-fitting contour, such as, in particular, an internal thread, and / or at least one fastening projection with a form-fitting contour, such as, in particular, an external thread. The mechanical coupling and / or fastening means of the first bearing interface are preferably designed for complementary interaction with a corresponding first bearing counter-interface on the side of the force arrangement.According to a possible solution, which is less preferred due to its lower flexibility once the power arrangement and the body soil tillage machine have been connected, the first bearing interface can be at least one joining formation for producing a joint connection which is intended to be non-detachable, such as by riveting or welding.

[0019] The first signal interface can comprise a plug and / or a socket and / or a plurality of plugs and / or sockets, or any other type of electrical or electronic coupling means. The first signal interface enables the exchange of signals and data between the thus-coupled components and / or assemblies through a preferably complementary coupling with a correspondingly designed first signal counter-interface.

[0020] The at least one working energy interface serves to transmit working energy provided by the power arrangement. Depending on the design of the respective consumer, the working energy interface can, for example, comprise or be a stub shaft or a hub, a transmission means arranged on a stub shaft, such as a gear or a friction wheel for a gear train, or a drive belt for a belt drive, and the like. At least one working energy interface of the at least one working energy interface can therefore be designed to transmit mechanical working energy, i.e., by inputting working energy or work output in the form of force and / or torque and movement.

[0021] Depending on the form in which the working energy is required at a consumer and provided by the power arrangement, a working energy interface of the at least one working energy interface can be an interface for fluid transmission, in particular for transmitting a liquid, such as hydraulic oil, or a gas, such as compressed air. In this case, the working energy interface can comprise or be a known fluid quick-action coupling. Such a case can arise, for example, if at least one consumer is a hydraulic motor or a hydraulic piston-cylinder arrangement, as is customary on soil cultivation machines, for which potential working energy is provided by the power arrangement in the form of a quantity of hydraulic fluid at a predetermined pressure level, which generally exceeds the atmospheric pressure of the environment.The same applies to the provision of potential working energy in the form of a quantity of gas at a predetermined gas pressure level for at least one pneumatic consumer, such as a pneumatic piston-cylinder arrangement.

[0022] Likewise, working energy can be electrical energy, for example when a consumer is an electrical consumer, such as an electric motor, a data processing device, such as the control device, lighting, and the like. In this case, at least one working energy interface of the at least one working energy interface can be an electrical interface, for example an electrical plug or an electrical socket. A plurality of working energy interfaces can each be designed as an electrical interface in order to enable the use of electrical energy in different forms on one and the same soil cultivation machine. In this way, electrical energy can be transmitted at different frequencies up to direct current and / or with different voltages and / or with different current intensities at different working energy interfaces.

[0023] In the case, which is more the rule than the exception, that several consumers operating according to different physical principles are provided on the tillage machine, the soil tillage machine preferably has a plurality of working energy interfaces on the side of its machine frame, preferably at least one for each form of energy transmitted from the power arrangement to the consumers.

[0024] For connection to the main body soil tillage machine, in particular to the machine frame, the power assembly has a first support device formed separately from the machine frame via the first bearing interface, which supports the power assembly. For this purpose, the first support device has a first bearing counter-interface for the physical connection of the power assembly to the main body soil tillage machine, in particular to the machine frame, preferably in a detachable manner as intended.The first support device, as a kind of adapter or "shape mediator" between the body of the tillage machine on the one hand and power arrangements on the other, is an essential component that enables the quick and uncomplicated, yet durable and safe arrangement of different power devices, which operate primarily on the basis of different physical principles, on the body of the tillage machine, in particular on the machine frame, during the manufacture of the tillage machine.

[0025] To attach the power device to the first support device, the power device has a power device interface, and the first support device has a power device counter-interface that is different from the first bearing counter-interface. In embodiments of the invention, the power device interface may not be directly coupled to the first bearing interface, for example due to its shape and / or its connection locations. Regardless of which power device is accommodated on the first support device, the first support device carrying the power device can always be connected to the body soil tillage machine, in particular to the machine frame, by using the first bearing interface and the first bearing counter-interface.If different force arrangements with different first support devices are provided for a soil tillage machine, the mechanical connectability of the different force arrangements with and thus their supportability on the body of the soil tillage machine can be ensured by using a quasi-standardized connection of the first bearing interface and the first bearing counter-interface.

[0026] The force device, in turn, is held on the first support device by a connection between the force device interface and the force device counter-interface. The force device interface can have one or more force device bearing formations. The force device counter-interface can have one or more force device abutment formations that can be coupled to the force device bearing formations, wherein the force device bearing formations and the force device abutment formations are or can be secured against lifting off from one another in the coupled state, in particular by form-fitting. With regard to the design of the force device bearing formations and abutment formations, what was stated above regarding the design of the first bearing interface and counter-interface applies mutatis mutandis, and vice versa.

[0027] Thus, different first support devices can be prepared for different force devices, the only structural constraint being the design or arrangement of a respective force device counter-interface. The respective force device counter-interface of a first support device is individually adapted to the respective force device to be accommodated and its force device interface.

[0028] Therefore, a plurality of different force arrangements can be provided for a production set of components for manufacturing the soil tillage machine. These force arrangements differ in terms of their force device, but only to a limited extent in terms of their respective first support devices. The first support devices preferably differ only in their respective force device counter-interface for attaching the respective force devices thereto, since each force device will have its own force device bearing formations in individually different shapes and / or at individually different locations.

[0029] Although it is not required, for reasons of simplified production and assembly, the first support devices of the different power arrangements of the production set, which are generally provided for the production of the soil tillage machine, are preferably designed and configured identically, with the exception of the individual power device counter-interface.

[0030] The advantage is obvious: by interposing the first support device, a body-mounted tillage machine without a power assembly for the purpose of accommodating a power assembly can always be designed essentially the same. Strictly speaking, this is also the case in the prior art, with the difference that only exactly one power assembly without a first support device fits onto and can be connected to the "body-mounted tillage machine" prepared in this way. According to the present invention, however, the power assembly, regardless of its type, can be connected quickly, easily, permanently, and securely to the machine frame of the body-mounted tillage machine as a preassembled module via the connection between the first bearing interface and the first bearing counter-interface. In contrast, the body-mounted tillage machine preferably has no interface on the machine frame side for directly accommodating the power assembly.

[0031] Since the first support interface and the first support counter-interface are an interface formation for connecting three-dimensional bodies to one another, both the first support interface and the first support counter-interface preferably comprise a plurality of cooperating and preferably complementary connection formations.

[0032] For reasons of increased strength and rigidity, the first bearing interface and the first bearing counter-interface are preferably designed for a direct connection to one another, preferably in a detachable manner as intended. However, a modular design of the soil tillage machine may alternatively require that the first bearing interface and the first bearing counter-interface be designed for an indirect connection, preferably in a detachable manner as intended, with at least one force-transmitting device interposed therebetween, wherein the force-transmitting device is different from the first support device. The prefix "force" is intended only to indicate that the transmission device serves to fix the force arrangement on the machine frame.The switching device can be an adapter, which can be connected on one functional side to the first support interface and which can be connected on its other functional side to the first support counter-interface. Such a force switching device can, for example, be another support device of a different functional arrangement than the force arrangement, as will be described in more detail below.

[0033] In order to be able to control the force arrangement to the necessary extent during operation and / or to detect states and operating conditions of the force arrangement and process them by the control device, the force arrangement can comprise a first signal counter-interface which is designed to establish a signal-transmitting signal coupling, preferably detachable as intended, with the first signal interface as part of the first signal connection. The first signal interface and the first signal counter-interface can preferably be connected to one another without tools, for example by establishing a plug-in connection. The first signal interface and the first signal counter-interface are preferably designed with physically complementary electrical contacts, for example as a plug and socket and / or as a contact shoe and contact tongue and the like.The first signal interface and the first signal counter-interface can each be implemented by a single interface body, which ensures particularly quick and easy connection. However, the first signal interface and the first signal counter-interface can also be formed by a plurality of separately connectable interface sub-bodies, for example, if signals from the force arrangement must be transmitted to different locations on the machine frame and / or via different cables and / or if the available installation space is insufficient for the construction of a single interface body.

[0034] An undesired disconnection of the established plug connection between the first signal interface and the first signal counter-interface can be prevented by positively locking the bodies carrying the respective contacts. Therefore, one interface of the first signal interface and the first signal counter-interface can have a locking formation, and the other interface can have a locking counter-formation that cooperates positively with the locking formation.

[0035] The first signal counter-interface can be connected to at least one sensor and / or to a local control device of the force device and / or to at least one actuator on the force device in a signal and / or data-transmitting manner.

[0036] To output the required working energy, the force arrangement can comprise at least one working energy counter-interface, which is designed to establish the working energy connection, preferably detachable as intended, with the at least one working energy interface, which transmits working energy. At least one working energy counter-interface of the at least one working energy counter-interface can be designed for direct connection to at least one working energy interface of the at least one working energy interface, and / or at least one working energy counter-interface of the at least one working energy counter-interface can be designed for indirect connection to at least one working energy interface of the at least one working energy interface, with a transmission device interposed.Such a transmission device can, for example, be a gear or linkage that connects a counter-interface for outputting mechanical working energy to a counter-interface for receiving mechanical working energy. If potential working energy is provided in the form of a quantity of fluid at a predetermined pressure level, in particular a quantity of hydraulic fluid, a transmission device can be implemented by a fluidic line arrangement, in particular a hose and / or pipe arrangement. If electrical working energy is provided, a transmission device can be an electrical line arrangement, optionally including electrical circuits, such as a transformer for changing the electrical voltage and / or a converter for generating and / or changing a frequency of an electrical current provided as working energy.A possible objection that electric current and electrical energy are different entities is only theoretically correct in this case, but irrelevant for the soil tillage machine in question. This is because the electrical work energy is used to perform work by the working device and is therefore provided as electrical work energy per unit of time, and consequently as electrical power. Electrical power is the product of an electrical voltage and the current flowing at this voltage. When using an inverter, both the electrical voltage provided and the current flow caused by this voltage have a frequency. It should be noted here that alternating electrical current on soil tillage machines is essentially required to power alternating or three-phase motors, whereas other electrical consumers, such as those found in vehicles, are generally operated with direct current.

[0037] According to the first law of thermodynamics, energy cannot be consumed. At most, a portion of the energy is dissipated into the environment as thermal loss without any further useful value. Since the required work energy is not available as mechanical energy, and is often not readily available in the required quantity in another form of energy, the power device preferably has at least one energy converter machine, which converts the operating energy fed into it from one form of energy into work energy from another form of energy on the output side. The power device can have an internal combustion engine and / or an electric motor and / or a fluid motor, in particular a hydraulic motor, as the energy conversion machine. In this case, the energy converter machine directly outputs mechanical energy to a moving output element, such as a rotating output shaft.The mechanical energy output by the energy conversion machine can be directly work energy and / or, as will be explained below, can be converted into another form of energy before being supplied to a consumer.

[0038] The soil tillage machine preferably has a power supply arrangement with at least one power supply device for supplying the power device with operating energy. Not only the use of different power arrangements, but also the varying availability of energy forms and / or energy quantities at different locations can make it advantageous to provide different power supply devices for installation on the main body of the soil tillage machine.

[0039] In principle, the power supply device can be directly and permanently mounted on the machine frame via individual fastening locations and means, without utilizing a modular design and without a second support device. Power supply device bearing formations on the power supply device are then directly physically connected to power supply device abutment formations on the machine frame. In this case, the power supply device is the power supply arrangement. However, it is preferably provided that the soil tillage machine also has a modular design with regard to its power supply arrangement as its energy source.

[0040] The basic concept of modularity in the present invention encompasses the basic structure of a functional assembly consisting of a functional device and a support device that supports the functional device. For example, the force assembly described above is constructed as a functional assembly.

[0041] Accordingly, the energy supply arrangement can comprise, as a further possible functional arrangement according to a preferred development of the soil cultivation device discussed here: the energy supply device, a second support device formed separately from the machine frame, wherein the second support device carries the energy supply device, and an operating energy counter-interface which is designed to produce an operating energy coupling, which transmits operating energy and is preferably detachable as intended, with an operating energy interface.

[0042] The second support device serves to simplify the use of different power supply arrangements on one and the same hull tillage machine.

[0043] The second support device comprises a second bearing counter-interface, which is designed for the physical attachment of the second support device to a second bearing interface, preferably in a detachable manner as intended. The second support device also preferably comprises a power supply device counter-interface with one or more power supply device abutment formations for physical connection to a power supply device interface of the respective power supply device in order to attach the power supply device to the second support device. The power supply device interface can comprise at least one power supply device bearing formation, which is physically connectable to the at least one power supply device abutment formation of the power supply device counter-interface.Of the possible multiple energy supply arrangements of an above-mentioned production set, preferably all second support devices each have at least the same second mounting counter-interface. However, the second support devices of the production set are likely to have different energy supply counter-interfaces adapted to the respective energy supply device to be mounted thereon.

[0044] Therefore, for a production set of components for manufacturing the soil tillage machine, a plurality of different power supply arrangements can be provided, which differ only in their power supply device. Although the second support devices can be designed differently as long as they only have the second bearing mating interface, the second support devices are preferably constructed essentially identically to facilitate production and assembly and preferably differ only in their respective power supply device mating interfaces, since each power supply device will have its own power supply device interface at individually different bearing locations.When a power supply device is fixed to a second support device, the specific design of the power supply device counter-interfaces no longer plays a role for the further assembly of the power supply arrangement thus formed on the body soil tillage machine.

[0045] According to a preferred development of the invention, in principle in accordance with what has been said above for the first bearing interface, the following applies to the second bearing interface and the second bearing counter-interface in particular: that the second bearing interface and the second bearing counter-interface can be designed for direct connection to one another, preferably in a detachable manner as intended, or that the second bearing interface and the second bearing counter-interface can be designed for indirect connection, preferably in a detachable manner as intended, with at least one energy supply switching device arranged therebetween, wherein the energy supply switching device is different from the second support device.

[0046] Again, the addition "energy supply" merely indicates the assignment of the switching device to the energy supply arrangement. Otherwise, the provisions of the present application regarding the power switching device apply to the energy supply switching device.

[0047] The second bearing interface can be formed directly on the machine frame.

[0048] The second support device can be the aforementioned force transmission device and can therefore support the force arrangement in addition to the energy supply device. Likewise, it is conceivable to attach the second support device to the first support device so that the energy supply arrangement can be mounted as a pre-assembled module on the first support device. In the latter case, the first support device supports the force device and the energy supply arrangement. Finally, the first support device can be the second support device. Then, the first support device supports the force device and the energy supply device. In all of the aforementioned embodiments, the first bearing interface is also the second bearing interface.In both of the first cases, the force assembly and the energy supply assembly can be arranged on the machine frame as a preassembled, higher-level functional module, despite their respective modular design. In the third case, the force device, the energy supply device, and the first support device also form a preassembled functional module. This allows optimal use of the installation space provided or reserved for functional modules on the machine frame, because the individual allocation of the available installation space between the force assembly and the energy supply assembly can take place on the support device directly supporting a functional device and a functional assembly.

[0049] Alternatively, the first and second bearing interfaces can be formed separately from one another in different areas on the main body soil tillage machine, in particular on the machine frame. In this case, the power arrangement and the energy supply arrangement can be fixed independently of one another directly on the main body soil tillage machine, in particular on the machine frame.

[0050] What is stated in the present application regarding the possible design of the first storage interface applies mutatis mutandis to the second storage interface.

[0051] The operating energy interface is designed to establish a connection, preferably detachable as intended, between the energy supply device and the force device, which transmits operating energy. The operating energy interface can be arranged on the first support device or on the force device. The operating energy can be electrical energy, so that the operating energy interface and the operating energy counter-interface can each have physically coordinated electrical contacts to establish an electrical line. The electrical contacts, which are dimensioned according to the expected electrical power to be transmitted, can be physically implemented as complementary male and female contacts. The operating energy interface and the operating energy counter-interface can be designed as a plug and socket.

[0052] As already explained above in connection with the first signal interface and the first signal counter-interface, the operating energy interface and the operating energy counter-interface, as well as any other interface-counter-interface combination of the present invention that transmits a fluid or electrical current, can also be secured against unwanted separation from one another, in particular can be locked together by positive engagement.

[0053] The operating energy can be energy stored in fluid, i.e., liquid and / or gaseous, fuels. The operating energy interface and the operating energy counter-interface can then be complementary coupling sections of a fluidic quick coupling to form a fluid line.

[0054] Less preferred than fundamentally possible, the operating energy can be provided as potential energy of a fluid volume under increased pressure. In this case, too, the operating energy interface and the operating energy counter-interface can be complementary coupling sections of a fluidic quick coupling to form a fluid line.

[0055] To provide operating energy, the energy supply device may comprise at least one device consisting of: a. a tank for storing fluid fuel, b. an internal combustion engine whose output shaft is coupled to the input shaft of a generator, c. an internal combustion engine whose output shaft is coupled to the input shaft of a fluid pump, d. an electric motor whose output shaft is coupled to the input shaft of a fluid pump, e. an electrical energy storage device, f. a photovoltaic arrangement, g. a fuel cell arrangement, h. an electrical line arrangement for connection to an external power source.

[0056] The list is expressly not exhaustive.

[0057] Variant a. provides usable energy stored in a fluid through combustion. Variants b., e., f., g., and h. provide electrical energy as operating energy. Variants c. and d. provide potential energy in the form of a fluid quantity under increased pressure, in particular a hydraulic fluid quantity. The fluid pump mentioned can be a gas compressor or a hydraulic pump. A hydraulic pump is preferred over a hydraulic fluid because of the high compressibility of gas. Variant a. can be combined with a variant from b., c., and g.

[0058] In order to be able to control the energy supply arrangement during operation to the extent required, if necessary, and / or to detect states and operating conditions of the energy supply arrangement and process them by the control device, the energy supply arrangement can comprise a second signal counter-interface, which is designed to establish a signal-transmitting signal coupling, preferably detachable as intended, with a second signal interface provided on the body soil tillage machine, which is connected to the control device and is part of a second signal connection. Preferably, the second signal interface and the second signal counter-interface can be connected to one another without tools, for example by establishing a plug-in connection.What has been said above regarding the design of the first signal interface and the first signal counter-interface, including their ability to be locked to one another as protection against unwanted separation, applies mutatis mutandis to the second signal interface and the second signal counter-interface.

[0059] In many cases, the working energy interface of a consumer, in particular of a plurality of consumers, is spatially too far away from the working energy counter-interface of the power arrangement to directly connect the working energy interface and the working energy counter-interface to one another in an energy-transmitting manner. To connect the working energy interface and the working energy counter-interface to one another, the soil tillage machine can therefore have a transmission arrangement. The transmission arrangement is then arranged in or on the soil tillage machine to establish at least a portion of the working energy connection. The transmission arrangement preferably has at least one mechanical output.

[0060] Preferably, a mechanical output of the at least one mechanical output is connected or connectable to the working device for transmitting torque through a mechanical transmission energy connection as part of the working energy connection to the at least one consumer, and / or at least one mechanical output of the at least one mechanical output is connected to an energy converter for converting mechanical energy into another energy form. Preferably, energy of the energy form converted by the at least one energy converter is transferable as working energy to the at least one consumer through a fluidic and / or electrical transmission energy connection as part of the working energy connection.According to a preferred embodiment of the invention, the energy converter connected to the at least one mechanical output of the transmission arrangement can comprise or be a fluid pump, in particular a hydraulic pump, for generating a fluid flow, in particular hydraulic flow and / or a fluid pressure level, in particular a hydraulic pressure level, and / or the energy converter can comprise or be an electrical generator.

[0061] The transmission energy connection is an energy connection in which the suffix "transmission" merely indicates that the energy connection is assigned to the transmission arrangement and serves to transmit energy between the transmission arrangement and at least one consumer. A mechanical transmission energy connection can comprise or be a drive belt and / or a gear and / or a linkage. A fluidic transmission energy connection can comprise or be at least one fluid line, in particular a fluid hose and / or a fluid pipe. An electrical transmission energy connection can comprise or be at least one electrical line.

[0062] Although the power device can output potential energy as work energy as described above, the power device preferably comprises a thermal or electric engine and outputs mechanical energy as work energy. The work energy counter-interface preferably has an output shaft or output hub for outputting the mechanical work energy. The transmission device can have an input shaft or input hub configured for connection to the work energy counter-interface. The transmission device can have an output shaft or output hub configured for connection to the work energy interface.

[0063] The transmission arrangement can comprise, as a functional or transmission device, a transfer case with an input shaft and at least one output shaft or generally one tapping point, preferably with a plurality of output shafts or generally with a plurality of tapping points, for energy or power that can be tapped off the output side of the transmission arrangement. The transmission arrangement can in particular comprise a so-called pump transfer case, which has at least one power take-off, preferably several power take-offs, to each of which a hydraulic pump is connected for drive by the transfer case. However, at least one hydraulic pump can, if necessary, be replaced by an electric generator and / or by a gas compressor if there is a corresponding demand for electrical power or compressed gas on the soil tillage machine.In addition, the pump distribution gear preferably has a mechanical main output, which makes the mechanical power input at the input of the pump distribution gear available on the output side of the pump distribution gear. This mechanical main output is preferably coupled to the working device, in particular to its working energy interface, in a force and / or torque-transmitting manner. The main output is generally the output of the distribution gear with the greatest power take-off. The main output and auxiliary drives, or main drive and auxiliary drives, usually also differ in the transmission ratio from the input to the output side. This is generally closer to 1 for the main output than for the auxiliary drives, and closer to 1 for the main drive than for the auxiliary drives.

[0064] In order to be able to control the transmission arrangement during operation to the extent required, if necessary, and / or to detect states and operating conditions of the transmission arrangement and process them by the control device, the transmission arrangement can comprise a third signal counter-interface, which is designed to establish a signal-transmitting signal coupling, preferably detachable as intended, with a third signal interface provided on the trunk soil tillage machine, connected to the control device, as part of a third signal connection. Preferably, the third signal interface and the third signal counter-interface can be connected to one another without tools, for example by establishing a plug-in connection.What has been said above regarding the design of the first signal interface and the first signal counter-interface, including their ability to be locked to one another as protection against unwanted separation, applies mutatis mutandis to the third signal interface and the third signal counter-interface.

[0065] Since a soil tillage machine as discussed here typically includes not just a plurality of consumers, but a plurality of consumers operating according to different physical principles, such as electric motors for motion drives and electric actuators, hydraulic motors and actuators, a mechanical working device, and pneumatic actuators, the at least one working energy interface preferably comprises a mechanical first working energy interface and / or a hydraulic second working energy interface and / or an electrical third working energy interface and / or a pneumatic fourth working energy interface. In particular, the traction drive uses hydraulic motors or electric motors.Fluidic actuators can, for example, be piston-cylinder arrangements which serve as steering actuators for steering the drives of the front and / or rear axle or as lifting arrangements for raising and lowering components, such as a roof of the control station and the like.

[0066] As already indicated above, the transmission arrangement may generally comprise a transmission device, the transmission device comprising: an input-side coupling formation for the, preferably detachable as intended, working energy transmitting coupling with the working energy counter-interface, and at least one output-side coupling formation for the, preferably detachable as intended, working energy transmitting coupling with the at least one working energy interface.

[0067] Again, what was said above regarding the power supply device also applies mutatis mutandis to the transmission device: in principle, without utilizing a modular design, the transmission device can be firmly mounted on the machine frame without a support device via individual fastening locations and means. A transmission device interface with transmission device bearing formations on the transmission device are then directly physically connected to individually designed, matching transmission device abutment formations on the machine frame. In this case, the transmission device is the transmission arrangement.

[0068] However, the use of different power arrangements on otherwise essentially identical hull-type tillage machines may make the use of different transmission arrangements necessary, or at least advisable. A third support device may serve to facilitate the use of different transmission arrangements.

[0069] Therefore, according to a preferred embodiment, the transmission arrangement comprises a third support device that supports the transmission device, wherein the third support device comprises a third bearing counter-interface that is designed for the physical connection, preferably in a detachable manner, of the third support device to a third bearing interface. The third support device preferably also comprises a transmission device counter-interface with transmission device abutment formations for physical connection to the transmission device interface of a transmission device in order to physically fix the transmission device to the third support device.

[0070] Therefore, for a manufacturing set of components for producing the soil tillage machine, a plurality of different transmission assemblies can be provided, which differ only in their transmission device. Although the third support devices can be designed differently as long as they only have the third bearing counter-interface, the third support devices are preferably constructed essentially identically to facilitate manufacturing and assembly and preferably differ only in their respective transmission device abutment points, since each transmission device will have its own transmission device bearing points at individually different locations.When a transmission device is fixed to a third support device, the specific design of the transmission device counter-interfaces no longer plays a role for the further assembly of the transmission arrangement thus formed on the body soil tillage machine.

[0071] For the third bearing interface and the third bearing counter-interface, the following applies: that the third support interface and the third support counter-interface are designed for direct connection to one another, preferably in a detachable manner as intended, or that the third support interface and the third support counter-interface are designed for indirect connection, preferably in a detachable manner as intended, with at least one transmission switching device arranged therebetween, wherein the transmission switching device is different from the third support device.

[0072] What has been said in the present application regarding the possible design of the first and second storage interface applies mutatis mutandis to the third storage interface.

[0073] The present invention also relates to a manufacturing kit for a self-propelled soil tillage machine as described and further developed above, the manufacturing kit comprising: a hull soil tillage machine as a machine base with a machine frame, a travel drive as a first consumer of the soil tillage machine, a chassis with a plurality of running gears that can roll on a ground, wherein the chassis supports the machine frame standing on the ground, wherein at least one running gear is drivable by the travel drive, a working device as a second consumer of the soil tillage machine, wherein the working device has a working tool designed for soil tillage, an operating station as the workplace of a machine operator operating the soil tillage machine, and a control device for controlling operation of the soil tillage machine, the first storage interface, the first signal interface and the at least one working energy interface, wherein the production set additionally comprises: a plurality of power arrangements,as described and developed above, wherein the power devices of at least two power arrangements provide working energy on the basis of different physical principles of action.

[0074] Further developments of this manufacturing kit are described in the above description in connection with the provision of a plurality of different energy supply arrangements and / or in connection with the provision of a plurality of different transmission arrangements.

[0075] For each support device from the above-mentioned first, second, and third support devices, it can comprise a support frame or a support structure, which absorbs the weight forces of the functional device and / or functional arrangement carried by the respective support device. To reduce weight without any significant loss of load-bearing capacity, the support frame or support structure can be a truss frame or truss structure, preferably comprising struts and connecting nodes. A truss of a support device can be designed to be dismantled as intended, or can be joined in a non-detachable manner as intended, for example by welding and / or riveting. A support device can be designed in one or more parts.In a multi-part design, at least two of the mechanical coupling and / or fastening means of the bearing counter-interface of the support device are provided on different, physically separate parts of the multi-part support device.

[0076] A control device mentioned in the present application is preferably a data processing device and, as such, preferably comprises at least one integrated circuit and a data memory. An operating program with control commands executable by the at least one integrated circuit can be stored in the data memory. Furthermore, the data memory can serve to store operating data during operation of the soil tillage machine.

[0077] In deviation from the above, the basic idea of ​​the present invention can also be implemented on a self-propelled soil tillage machine with a power device attached directly to the machine frame, i.e. without the intermediate arrangement of a first support device with a first bearing counter-interface and a power device counter-interface, the energy supply arrangement of which is connected to the machine frame with the intermediate arrangement of a second support device described above that supports it, using the second bearing interface and second bearing counter-interface also described above. Such a soil tillage machine then has a second support device, but no first support device. Likewise, it has, for example, a second bearing interface, but no first bearing interface.

[0078] Accordingly, in a second embodiment, the present invention also relates in principle to a self-propelled soil tillage machine, comprising a trunk soil tillage machine, wherein the trunk soil tillage machine comprises: a machine frame, a travel drive as a first consumer of the soil tillage machine, a chassis with a plurality of running gears that can roll on a ground and that supports the machine frame standing on the ground, wherein at least one running gear is drivable by the travel drive, a working device as a second consumer of the soil tillage machine, wherein the working device has a working tool designed for soil tillage, an operator's station as the workplace of a machine operator operating the soil tillage machine, and a control device for controlling operation of the soil tillage machine, and a power device with at least one energy converter machine, wherein the power device is designed to provide working energy for operation of at least one of the consumers of the soil tillage machine, wherein the hull soil tillage machine is designed to receive a power supply arrangement, wherein the power supply arrangement comprises a power supply device which is designed to supply the power device with operating energy.

[0079] This soil tillage machine of the second embodiment is further developed according to the basic idea of ​​the present invention in that the trunk soil tillage machine further comprises: a second storage interface for physically connecting the power supply arrangement to the hull soil tillage machine, and an operating energy interface for establishing an operating energy connection between the power supply arrangement and the power device, wherein the power supply arrangement comprises: a power supply device, an operating energy counter-interface which is designed to establish an operating energy coupling with the operating energy interface which transmits operating energy, and a second support device designed separately from the machine frame, wherein the second support device supports the power supply device and wherein the second support device comprises a second bearing counter-interface which is designed to physically fix the second support device to the second bearing interface.

[0080] The energy supply device has a power supply device interface. The second support device has a power supply device counter-interface that is different from the first support counter-interface. The energy supply device is mounted on the second support device by a connection between the power supply device interface and the power supply device counter-interface.

[0081] According to an advantageous development, the hull-mounted soil tillage machine can have a second signal interface for establishing a signal-transmitting second signal connection between the control device and the power supply arrangement. Thus, the control device can, if necessary, control the operation of the power supply arrangement and / or record operating data and states of the power supply arrangement. The power supply arrangement then preferably has a second signal counter-interface for connection to the second signal interface.

[0082] Likewise, the present invention relates to a second embodiment of a manufacturing kit adapted to the above second embodiment of the self-propelled soil tillage machine. Consequently, the present invention also relates to a manufacturing kit for a self-propelled soil tillage machine of the second embodiment, comprising a body soil tillage machine as described on page 27, lines 4 to 28, with the second bearing interface, optionally the second signal interface, and the operating energy interface as a machine base. The manufacturing kit of the second embodiment additionally comprises a plurality of energy supply arrangements, the energy supply devices of which provide operating energy based on different physical operating principles and / or in different energy forms.

[0083] Again, operating energy is a different form of energy from work energy.

[0084] Further developments and configurations of the energy supply arrangement, the energy supply device, the power device, the chassis, the travel drive, the working device, the control device, the machine frame as well as the interfaces, couplings and connections explained within the framework of the first embodiment are also further developments and configurations of the second embodiment, both with regard to the soil tillage machine and with regard to the production kit, insofar as they do not contradict the basic design of the second embodiment described above.

[0085] For both the first and the second embodiment, the described further developments of the soil tillage machine are also further developments of the production kit in the sense that a correspondingly further developed production kit contains those components from the main soil tillage machine and other components that are required to manufacture the further developed soil tillage machine.

[0086] As a rule, if the power device is directly connected to the machine frame, any transmission device coupled to the power device as a section of the working energy connection will also be directly coupled to the machine frame. Preferably, the energy supply arrangement is then the only one of the above-mentioned arrangements that is connected to the machine frame with the second support device interposed.

[0087] The second embodiment is particularly interesting for energy supply arrangements that supply an electrical power device with electrical operating energy. In this case, as also in the first embodiment, the power device can comprise several separately designed and arranged partial power devices, each of which outputs working energy to a consumer. The number of consumers can be the same as the number of partial power devices, can be greater than the number of partial power devices, or can be less than the number of partial power devices.

[0088] The present invention will be explained in more detail below with reference to the accompanying drawings. It shows: Fig. 1 is a roughly schematic side view of a first part of a first embodiment of a manufacturing kit according to the invention and of a self-propelled soil cultivating machine according to the invention formed therefrom, comprising a body soil cultivating machine, a first power arrangement, a first energy supply arrangement and a first transmission arrangement, Fig. 2 is a roughly schematic side view of a second part of the first embodiment of the manufacturing kit according to the invention, comprising a second power arrangement, a second and a third energy supply arrangement, a second transmission arrangement, and a first and a second support device in isolation, and Fig. 3 a roughly schematic partial view of a second embodiment of the soil tillage machine and the manufacturing kit according to the present application.

[0089] The Figure 1 and 2show, by way of example, a section of a first embodiment of a production kit 8 according to the invention for producing a self-propelled soil tillage machine 10 in the form of a large soil or road milling machine.

[0090] The viewer of Figure 1 looks at a soil tillage machine 10 or "machine" 10 for short, which is made from components of the production set 8, in the direction of the plane of the drawing of Figure 1 orthogonal cross machine direction Q. A machine longitudinal direction orthogonal to the cross machine direction Q is denoted by L and runs parallel to the plane of the drawing of Figure 1 . A machine height direction H also runs parallel to the drawing plane of Figure 1 and orthogonal to the machine longitudinal direction L and the machine cross direction Q. The arrowhead of the machine longitudinal direction L in Figure 1points in the forward direction. The machine height direction H runs parallel to the yaw axis Gi of the machine 10, the machine longitudinal direction L runs parallel to the roll axis Ro, and the machine cross direction Q runs parallel to the pitch axis Ni.

[0091] The self-propelled tillage machine 10 includes a trunk tillage machine 11 as a machine base.

[0092] The hull-type soil tillage machine 11 comprises a machine frame 12, which forms the basic framework for a machine body 14. The machine body 14 comprises the machine frame 12 and components of the machine 10 and the hull-type soil tillage machine 11 that are connected to the machine frame 12 and, if necessary, movable relative to the frame.

[0093] The machine body 14, the number of components of which increases during the assembly of the self-propelled tillage machine 10, comprises on the body tillage machine 11 front hydraulic lifting columns 16 and rear hydraulic lifting columns 18, which are connected at one end to the machine frame 12 and at the other end to front undercarriages 20 and rear undercarriages 22, respectively.

[0094] In the side view of Figure 1 It cannot be seen that the machine 10 has two lifting columns 16 and 18, respectively, in both its front end region and its rear end region, each with a running gear 20 and 22 connected thereto. The front lifting columns 16, as well as the rear lifting columns 18, are coupled to the running gears 20 and 22, respectively, in a manner known per se, by means of a running gear connecting structure 24, for example a connecting fork spanning the respective running gear 20 and 22 in the transverse machine direction Q.

[0095] The undercarriages 20 and 22 are illustrated as tracked undercarriages. In the illustrated embodiment, they are essentially identical in design and form the chassis 26 of the machine 10 and the main body soil tillage machine 11. Individual or all of the undercarriages 20 and / or 22 may also be wheeled undercarriages. Each of the undercarriages 20 and 22 is motor-driven, in the illustrated embodiment by a hydraulic motor 28.

[0096] In the illustrated embodiment, the carriage 20 and the carriage 22, with possible directions of travel indicated by the double arrow D, each have a radially inner receiving and guide structure 30, on which a revolving track chain 32 (labeled only on the front carriage 20) is arranged and guided for revolving movement. The inner guide structure is connected to the carriage connecting structure 24 so that it can be tilted about a tilt axis parallel to the pitch axis Ni.

[0097] The distance between the machine frame 12 and the drives 20 and 22 can be changed by the hydraulic lifting columns 16 and 18.

[0098] The soil tillage machine 10 or the hull soil tillage machine 11 has a control station 34 from which a machine operator can control and operate the machine 10 via a control panel 36 with a control device 38 accommodated therein.

[0099] A working device 40 is arranged beneath the machine frame 12, here for example as a milling device 40 with a milling drum 44 accommodated in a milling drum box 42 as a working tool of the working device 40. The milling drum 44 is rotatable about a milling axis R running in the transverse machine direction Q in order to be able to remove subsoil material during soil cultivation, starting from the contact surface AO of the subsoil U, with a milling depth determined by the relative height of the machine frame 12 above the contact surface AO. The height adjustability of the machine frame 12 by the lifting columns 16 and 18 therefore also serves to adjust the milling or general working depth of the machine 10 during soil cultivation. Alternatively or additionally, the milling drum 44 can be mounted on the machine frame 12 so that its height can be adjusted relative to the latter.

[0100] For those in Figure 1The arrangement of the milling device 40 in the machine's longitudinal direction L between the front and rear drives 20 and 22 is typical for the large road milling machine shown. Such large milling machines, as well as soil-removing machines in general, can have a conveyor belt to transport removed soil material away from the machine 10. A conveyor belt, which is also generally present on the machine 10, is shown in FIG. 1 for reasons of better clarity. Figure 1 not shown.

[0101] The lifting column 16 and with it the running gear 20 can be rotated about a steering axis S by means of a hydraulic steering device 46 which is only roughly schematically indicated. Preferably additionally, but also alternatively, the rear lifting column 18 and with it the running gear 22 can be rotated about a steering axis parallel to the steering axis S by means of a steering device.

[0102] The operator's platform 34 is covered by a protective roof structure 48, which includes a protective roof 50. The protective roof 50 is arranged on the machine frame 12 and can be raised and lowered by means of a motion guide 52 and a hydraulic motion drive 54. In Figure 1 the protective roof 50 is shown in its raised operating position in which the machine 10 is ready for soil cultivation operation.

[0103] A first power assembly 56 is arranged on the main tillage machine 11 to form the tillage machine 10. The main tillage machine 11 receives a power assembly as a central power plant of the machine 10, which provides essentially the entire working power of the machine 10.

[0104] The first power arrangement 56 comprises an internal combustion engine 58 as a first power device and comprises a first support device 60. To explain the design of the support device 60, reference is made to Figure 2 where it is shown in a unique position.

[0105] The body-type soil tillage machine 11 has a first bearing interface 62 on the machine frame 12 or on the machine body 14, to which the first support device 60 is secured by a first bearing counter-interface 64 arranged on the first support device 60. In the illustrated embodiment, the first bearing interface 62 is symbolized by three coupling formations 62a, to which three coupling counter-formations 64a of the bearing counter-interface 64 of the first support device 60 are coupled. To ensure particularly secure positioning of the first support device 60 on the machine frame 12, the coupling formations 62a and the coupling counter-formations 64a are complementary. The coupling formations 62a and the coupling counter-formations 64a can be secured to one another by threaded engagement or by other engagement.

[0106] The first bearing interface 62 with its coupling formations 62a and the first bearing counter-interface 64 with its coupling counter-formations 64a are shown again for the sake of clarity in Figure 2 marked.

[0107] The first bearing counter-interface 64 is arranged on the functional side 60a of the first support device 60 associated with the machine frame 12. In this case, the functional side 60a is also a physical side of the first support device 60.

[0108] The internal combustion engine 58 is arranged on the functional side 60b of the first support device 60, opposite the functional side 60a. For this purpose, the first support device 60 has a power device counter-interface 66 on the functional side 60b, which in turn is also a physical side of the first support device 60, to which the internal combustion engine 58 is mounted by means of its power device interface 68. The power device interface 68 and the power device counter-interface 66 can be configured like a conventional engine mount for mounting an internal combustion engine in a vehicle frame.

[0109] In Figure 1 The force device counter-interface 66 is symbolized by two force device abutment formations 66a. The force device interface 68 is symbolized by two force device bearing formations 68a.

[0110] On the functional side 60b assigned to the functional devices, a pump distribution gear 70 is also arranged as a transmission device. The first support device 60, which in the illustrated embodiment supports the transmission device and is therefore also a third support device within the meaning of the introduction to the description, has a transmission device counter-interface 72 on its functional side 60b, symbolized by two transmission device abutment formations 72a.

[0111] The pump distribution gear 70 with its transmission interface 74 is mounted in a manner known per se on the transmission interface 72. The transmission interface 74 is symbolized by two transmission bearing formations 74a, of which Figure 1 For the sake of clarity, only the rights are marked with a reference symbol.

[0112] The pump distribution gear 70 and the first and third support devices 60 form a transmission arrangement 76.

[0113] The internal combustion engine 58, for example a diesel combustion engine, has as output element for outputting work power or work energy an orthogonal to the plane of the drawing of Figure 1 extending output shaft 78 as a working energy counter-interface, which in the operational state is coupled to an input hub 80 of the pump distribution gear 70 in a torque-transmitting manner.

[0114] The pump distribution gear 70 has as a first mechanical output a pulley 82, which is driven by a Figure 1The only indicated drive belt 83 can be completed with a belt pulley 84 coupled to the milling drum 44 in a torque-transmitting manner as a working energy interface to a belt drive. A reduction gear can be arranged between the milling drum-side pulley 84 and the milling drum 44, which preferably reduces a rotational speed of the pulley 84 toward the milling drum 44 in one transmission ratio and increases a torque in the reciprocal transmission ratio. Since the transmission-side pulley 82 transmits the working energy required for the operation of the milling device 40, the transmission-side pulley 82 forms the main output of the pump distribution gear 70.

[0115] A hydraulic pump 86 is arranged on a further output, more precisely on a power take-off of the pump distribution gear 70. During operation, the hydraulic pump 86 outputs hydraulic fluid at an increased pressure level as fluidic working energy to a quick-coupling formation 88 as a coupling formation. The fluidic working energy of the hydraulic pump 86 can be used by the hydraulic motors 28 for propelling the soil tillage machine 10, by the hydraulic movement drive 54 of the protective roof structure 48 for raising and lowering the protective roof 50, and by the steering device 46 for steering the front lifting columns 16 and / or the rear lifting columns 18. The hydraulic pump 86 can raise a quantity of hydraulic fluid present on the soil tillage machine 10 to an increased pressure level via the quick-coupling formation 88.

[0116] The internal combustion engine 58 has its own engine control unit 90, which, during operation, forms a component control unit subordinate to the control unit 38. To connect the engine control unit 90 of the internal combustion engine 58 to the control unit 38 of the main body soil tillage machine 11 or the soil tillage machine 10, the main body soil tillage machine 11 has a first signal interface 92, to which a first signal counter-interface 94 of the internal combustion engine 58 can be coupled for data and signal transmission. One interface of the first signal interface 92 and the first signal counter-interface 94 can comprise a plug, and the other interface can comprise a matching socket.

[0117] To supply fuel as a supplier of operating energy for the operation of the internal combustion engine 58, the internal combustion engine 58 preferably has a quick coupling formation 96 as an operating energy interface through which fuel can be supplied to the internal combustion engine 58.

[0118] In order to ensure prolonged operation of the internal combustion engine 58, an energy supply arrangement 98 is arranged on the hull soil tillage machine 11. The energy supply arrangement 98 supplies the internal combustion engine 58 with operating energy, in this case fuel, during its operation.

[0119] The energy supply arrangement 98 has a modular design and comprises a tank 100 as the energy supply device and a second support device 102 for attachment to the machine frame 12 of the main tillage machine 11 or the tillage machine 10. A quantity of fuel is accommodated in the tank 100, which can be supplied to the internal combustion engine 58 through a fuel supply line 104 as an operating energy line and as part of an operating energy connection 106. For this purpose, the fuel supply line 104 carries a quick-coupling counter-formation 108 as an operating energy counter-interface, which can be quickly and tool-free combined with the internal combustion engine-side quick-coupling formation 96 to form the operating energy connection 106. In the coupled, fluid-transmitting state, the quick-coupling formation 96 and the quick-coupling counter-formation 108 form an operating energy coupling.

[0120] A feed module 110 can be arranged in the fuel tank 100, which can be controlled by the control device 38. For this purpose, the fuel tank 100 has a second signal counter interface 112, which is connected to a Fig. 1 not shown second signal interface 122 on the side of the trunk soil tillage machine 11 for the transmission of signals and data (see Figure 2 ). The second signal interface 122 can be configured like the first signal interface 92.

[0121] The fuel tank 100, as an energy supply device of the soil tillage machine 10, has an individual energy supply device interface 114, by means of which it is secured to a likewise individual energy supply device counter-interface 116 of the second support device 102. For this purpose, the energy supply device interface 114 has a plurality of energy supply device bearing formations 114a, shown only symbolically, each of which is coupled to a complementary energy supply device abutment formation 116a and physically secured thereto.

[0122] The energy supply arrangement 98 is secured via the second support device 102 to a second bearing interface 118 of the machine frame 12 directly on the machine frame 12 or machine body 14. The second support device 102 has a second bearing counter-interface 120 for securing it to the second bearing interface 118. The second bearing interface 118 is in Figure 1 represented by two symbolically represented coupling formations 118a, the second storage counter-interface 120 is in Figure 1 represented by two symbolically depicted complementary coupling counterformations 120a.

[0123] The second bearing counter-interface 120 is arranged on the functional and also physical side 102a of the second support device 102 facing the machine frame 12, and the energy supply device counter-interface 116 is arranged on the opposite functional and physical side 102b of the second support device 102 facing away from the machine frame 12.

[0124] Thus, the soil tillage machine 10 can be constructed modularly with regard to its supply of working energy or working performance and can be adapted to the respective customer requirements or boundary conditions of use.

[0125] In Figure 2 Further components of production set 8 are shown. Basically functionally identical arrangements, facilities, interfaces and formations as in Figure 1 , which differ from those of Figure 1 are designed in Figure 2are provided with the same, but primed reference symbols. For their explanation, reference is expressly made to the description of the respective reference symbols. Figure 1 unless additional information is expressly provided.

[0126] In Figure 2The section with the bearing interfaces 62 and 118 of the trunk soil tillage machine 11 is shown at the bottom left. Also shown there is a second signal interface 122 for the possible signal and data transmission connection of the energy supply arrangement 98, also as embodiment 98' or 98", to the control device 38, as well as a third signal interface 124 for the possible signal and data transmission connection of the transmission arrangement 76, also as embodiment 76', to the control device 38. The energy supply arrangement 98 to be connected in each case, optionally as embodiment 98' or 98", then has a corresponding second signal counter-interface 112, and the transmission arrangement 76 to be connected in each case, optionally as embodiment 76', has a corresponding third signal counter-interface 126.

[0127] Thus, in deviation from the transmission arrangement 76, the Figure 1another transmission arrangement 76', again as a pump distribution gear 70', is not fixed to the first support device 60 and also not to a separate third support device, but is mounted directly on the machine frame 12 via corresponding transmission device bearing formations 74a' and abutment formations 72a'.

[0128] The pulley 82 on the output side of the pump distribution gear 70' is unchanged, since the pulley 84 as the working energy interface of the soil tillage machine is also unchanged. However, the pump distribution gear 70' has Figure 2A total of four mechanical power take-offs, each with a hydraulic pump 86' driven by them, each of which has a fluidic quick-coupling formation 88 for discharging hydraulic fluid under increased pressure. Of the four hydraulic pumps 86' of the pump distribution gear 70', only the two on the right are provided with reference numerals for the sake of clarity.

[0129] By using four hydraulic pumps 86', the use of a local control device 128 for controlling the pump distribution gear 70' or generally the transmission arrangement 76' can be provided, which can be coupled to the third signal interface 124 via a third signal counter interface 126.

[0130] In Figure 2Also shown is an alternative power assembly 56' with an electric motor 58' as the power device. The output shaft 78', as the working energy counter-interface of the power assembly 56' of the electric motor 58', is torque-transmittingly connectable to the input hub 80' of the pump distribution gear 70'.

[0131] As an electrical power arrangement 56', the alternative power arrangement 56', unlike the first power arrangement 56 with the internal combustion engine 58, requires operating energy in the form of electrical energy. For this purpose, an alternative energy supply arrangement 98' is provided, which has an accumulator 130 as an energy storage device. Accordingly, the operating energy interface 96' and the operating energy counter-interface 108' are designed as electrical quick-coupling components, such as a plug and socket. Electrical cables therefore connect the electric motor 58' and its power supply, the accumulator 130.

[0132] Deviating from Figure 1 The energy supply arrangement 98' is connectable via the second support device 102' not directly to the machine frame 12, but indirectly via the first support device 60' to the machine frame 12. The first support device 60' then also serves as the energy supply switching device. In this case, the bearing counter-interface 64 is functionally combined with the first and second bearing counter-interfaces 64 and includes not only the coupling counter-formations 64a, but also the coupling counter-formations 64a'. The coupling counter-formations 120a' of the second bearing counter-interface are arranged on the second support device 102'. When the power arrangement 56' and the energy supply arrangement 98' pre-assembled to form a functional module are arranged, the coupling formations 62a and 118a on the body soil tillage machine 11 form a common bearing interface of the functional module, which is both the first and the second bearing interface.

[0133] The coupling counter-formations 64a and the coupling counter-formations 120a are shown in the figures merely as examples with different shapes to graphically support their distinguishability. In fact, the coupling counter-formations 64a and the coupling counter-formations 120a can be designed with identical shapes. This is even preferred in terms of manufacturing effort. The described possible identical shape also applies to the coupling formations 62a and the coupling formations 118a, as well as to at least two abutment formations consisting of the force device abutment formations 66a, the transmission device abutment formations 72a', and the energy supply device abutment formations 116a, as well as to at least two bearing formations consisting of the force device bearing formations 68a, the transmission device bearing formations 74a', and the energy supply device bearing formations 114a.

[0134] Instead of the energy supply arrangement 98' with the electric accumulator 130, a module of an energy supply arrangement 98" with a fuel cell 132 and a fuel tank 100" connected thereto can be used for conversion into electrical energy in the fuel cell 132. A control device 113 controlling the operation of the fuel cell 132 can be connected to the control device 38 on the mainframe soil tillage machine 11 via the second signal counter-interface 112'. Such an energy supply arrangement 98" can also be prepared on a second support device 102' for arrangement on the mainframe soil tillage machine 11. The second support device 102', like that of the energy supply arrangement 98', can be mounted indirectly via the first support device 60' or directly on the machine frame via a second mounting interface.

[0135] Likewise, the power supply arrangement 98‴ with a cable drum 134 arranged thereon with a line arrangement 136 for connection to a construction site power supply can be used as a module prepared on the soil tillage machine 10.

[0136] Thus, due to the different arrangements present in the production kit 8, the soil tillage machine 10 can be equipped with different power engines and with different energy supply arrangements for supplying operating energy as well as with different transmission arrangements and can be configured for different application conditions with relatively little effort.

[0137] The example of different modules given above is merely exemplary and not exhaustive.

[0138] In Fig. 3A second embodiment of a hull-type tillage machine designed according to the principles of the present invention is shown and designated 1011. A second embodiment of the manufacturing kit designed according to the principles of the present invention is also shown and designated 1008. The arrangement of one of the various power supply assemblies 1098', 1098" or 1098‴ shown at the second mounting interface 1118 completes the hull-type tillage machine and produces a second embodiment of a self-propelled tillage machine.

[0139] The same and functionally equivalent arrangements, devices, components and component sections as in the corresponding first embodiments relating Figure 1 and 2 are in Figure 3 with the same reference numerals, but increased by the number 1000.

[0140] The second embodiments of soil tillage machine or hull soil tillage machine 1011 and production kit 1008 will be described below only insofar as they differ from the corresponding first embodiments of the Figure 1 and 2 whose description is also relevant for the explanation of Figure 3 applies unless otherwise stated below. The description of the Figure 1 and 2 is therefore also used to explain Figure 3 expressly referred to.

[0141] The essential difference between the trunk soil tillage machine 11 of the first embodiment and the trunk soil tillage machine 1011 is that the power assembly 1056' with the electric motor 1058' as the power device, as well as the transmission assembly 1076' in the exemplary form of the pump distribution gear 1070', are directly and firmly connected to the machine frame 1012 via corresponding bearing and abutment formations. The power assembly 1056' and the transmission assembly 1076' are thus part of the trunk soil tillage machine 1011.

[0142] Only the energy supply arrangements 1098', 1098" and 1098‴ can be connected, preferably detachably, to the trunk soil tillage machine 1011 via a second bearing interface 1118 and a second bearing counter-interface 1120 of a second support device 1102 or 1102', which is preferably complementary to this.

[0143] Since the second support device 1102 or 1102' are coupled to the machine frame 1012 or the machine body 1014 via the second bearing interface 1118 and the second bearing counter-interface 1120, all second support devices 1102 or 1102' of Figure 3 the same second bearing counter interface 1120. The Figure 3 The only second support device 1102' is apostrophized because, in comparison to the other second support devices 1102, it has a different energy supply device counter-interface 1116', which, however, is only intended to illustrate by way of example that a second support device can have any suitable energy supply device counter-interface on its functional side assigned to the energy supply device.

[0144] The Figure 3shows only one power device 1058'. In fact, several partial power devices can be arranged on the body soil tillage machine 1011, which can be supplied with electrical energy by a power supply arrangement 1098' or 1098" or 1098‴ received at a second bearing interface 1118.

[0145] In this way, a soil tillage machine can be equipped with the most suitable power supply arrangement to meet individual requirements.
