Description

[0001] The present invention relates to a self-propelled soil cultivation machine with a body soil cultivation machine according to the preamble of claim 1. The body soil cultivation machine comprises, among other things: a machine frame, a drive system as a first consumer of the soil cultivation machine, a chassis with a plurality of running gear that can roll on a surface and which supports the machine frame standing on the surface, wherein at least one running gear can be driven by the drive system, a working device as a second consumer of the soil cultivation machine, wherein the working device has a working tool designed for soil cultivation, an operator's station as a workplace for a machine operator operating the soil cultivation machine, and a control device for controlling the operation of the soil cultivation machine.

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

[0003] A self-propelled soil cultivation machine of this type is known, for example, from EP 4 071 302 A1 or also from DE 10 2014 001 839 A1.

[0004] Other soil cultivation machines are known 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 refers to a road milling machine, a stabilizer, a recycler, or a surface miner as the self-propelled soil cultivation machine. The working tool is therefore preferably a rotating working tool designed for removing material from the soil, in particular a milling drum with a plurality of milling cutters which are mounted on the outside of a milling drum tube, preferably in a helical arrangement.

[0005] From EP 0 628 661 B1, an electrically operated road paver with a detachable power supply unit is known. The power supply unit can be detached for repair and maintenance purposes and, if necessary, replaced with a similar power supply unit. The detached power supply unit can either be used to power other functional assemblies on a construction site or can be connected to the road paver via a cable and supply it with power remotely.

[0006] US patent 2021 / 107738 A1 discloses a mobile material handling device with a modular internal combustion engine assembly. The modular internal combustion engine assembly comprises the internal combustion engine, a combustion air inlet, a hydraulic oil cooler, a charge air cooler, a pump section with feed pumps for hydraulic, fuel, and coolant supply pumps, an exhaust aftertreatment subassembly, an exhaust outlet, a fuel cooler, and a radiator.

[0007] Electric vibratory compactors with interchangeable drive units are known from US patent 2022 / 0186453 A1.

[0008] Currently, self-propelled soil cultivation machines, such as road milling machines, stabilizers, recyclers and surface miners, are assembled from their individual parts, with individual functional units, such as an internal combustion engine as the central power source of the soil cultivation machine, a track with a rotating crawler, the working device and / or the working tool, and the like, being attached as pre-assembled modules to the self-propelled soil cultivation machine being created during assembly.

[0009] Diverse secondary requirements for soil cultivation machinery beyond the direct soil cultivation itself, such as noise and dirt emissions in different operating areas (particularly due to varying legislation), differing availability of energy quantities and / or forms, and varying technical constraints for each specific application), may no longer be adequately met by a single soil cultivation machine. Manufacturers of self-propelled soil cultivation machinery are therefore facing the increasingly demanding challenge of providing a soil cultivation machine that is as suitable as possible for each specific application.

[0010] This provision of soil cultivation machines that are appropriately equipped for a given processing range, but are constructed differently to fulfill the processing range while taking into account existing secondary requirements, leads, without further measures, to a considerable additional effort at least in assembly and consequently probably also to an increased space requirement for assembly, since, without further measures, it cannot be expected that conceptually different soil cultivation machines with regard to their energy conversion and / or their energy transmission can be easily assembled at one and the same assembly location.

[0011] It is therefore an object of the present invention to reduce the effort required to provide soil cultivation machines which are suitable for performing one and the same soil cultivation spectrum, but which differ conceptually with regard to energy conversion and / or energy transfer, which is always required in a soil cultivation machine, and to enable an economical diversification of the product range of soil cultivation machines for one and the same cultivation spectrum.

[0012] Even today, manufacturers of tillage equipment offer a variety of machines for a similar range of applications, based on the same physical operating principle. These machines differ primarily in their performance limits, meaning essentially in the dimensions of their working unit, particularly their implements, and consequently in the power consumption of these implements. Thus, different tillage machines are offered for different working widths and / or different performance levels, which in turn can be equipped with different implements for similar soil removal operations, but with different results.

[0013] In the particularly preferred case of destructive soil cultivation, different removal widths can be achieved using soil cultivation machines with different width working tools. Different removal priorities, such as maximum 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 cutters.

[0014] The range of operations that a soil cultivation machine can perform results from the totality of work tools that can be attached to one and the same base unit. The base unit is essentially defined by its machine frame, which sets limits for the work attachments and / or work tools that can be mounted to it. In the area of ​​soil-removing milling machines, which is of particular interest here, various milling tools can be mounted on one and the same base unit. These tools may differ in their respective milling widths, which may be selected within a predetermined milling width range, and / or which may differ in the number and / or shape of the milling cutters attached to them.

[0015] Regardless of the range of different working devices and tools available for a given soil cultivation machine, the rest of the soil cultivation machine, i.e. the basic unit, usually remains unchanged by the component selection in the area of ​​its working device.

[0016] The present invention is therefore not based on the question of how one and the same soil cultivation machine can be used for different cultivation tasks, but rather on how one and the same soil cultivation machine can best fulfill one and the same soil cultivation task under different legal, technical, and / or economic constraints. This does not, of course, preclude changing the working equipment and / or working tool on a soil cultivation machine according to the invention. However, such a change is not necessary for solving the problem defined above.

[0017] This problem is solved according to the invention by a self-propelled soil cultivation machine with all the features of claim 1. The soil cultivation machine has a modular design with respect to its power arrangement as its power source. According to the invention, the soil cultivation machine also has a modular design with respect to its energy supply arrangement as its energy source.

[0018] 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 during the planning of the soil cultivation machine and to install it on the soil cultivation machine.

[0019] To achieve the modular design with regard to the force arrangement, the body-type soil cultivation machine includes: a first bearing interface for the, preferably detachable, physical connection of the force arrangement with the machine frame, a first signal interface for establishing a, preferably detachable, signal-transmitting first signal connection between the control device and the force arrangement, and at least one working energy interface for establishing a working energy-transmitting connection between the at least one consumer and the force arrangement, preferably detachable.

[0020] The aforementioned interfaces allow the force arrangement to be mechanically connected to the body-mounted soil cultivation machine via the first bearing interface, via signal and data transmission via the first signal interface, and via the working energy interface for the transmission of working energy to at least one consumer.

[0021] The connection of an arrangement mentioned in the present invention, such as the force arrangement mentioned above, with the body-type soil cultivation machine ultimately means a direct or indirect connection of the components with the machine frame.

[0022] The first bearing interface can have a plurality of mechanical coupling and / or fastening means. Possible coupling means include, for example, bearing recesses or bearing projections. Possible fastening means include connecting elements, such as at least one fastening opening with a positive-locking contour, such as, in particular, an internal thread, and / or at least one fastening projection with a positive-locking 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 force arrangement side.According to a possible but less preferred solution, due to its lower flexibility after the connection of the power arrangement and the body-based soil processing machine has been established, the first bearing interface can at least be a joining formation for producing a permanently inseparable joining connection, such as by riveting or welding.

[0023] 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 coupled components and / or assemblies through, preferably complementary, coupling with a suitably designed first signal counterpart interface.

[0024] The at least one energy interface serves to transmit energy provided by the force arrangement. Depending on the design of the respective consumer, the energy interface can, for example, comprise or be a shaft stub or hub, a transmission element arranged on a shaft stub, such as a gear or friction wheel for a gear train, or a drive belt for a belt drive, and the like. At least one energy interface of the at least one energy interface can therefore be designed for the transmission of mechanical energy, i.e., by inputting energy or work power in the form of force and / or torque and motion.

[0025] Depending on the form in which the work energy is required by a consumer and supplied by the power arrangement, a work energy interface of the at least one work energy interface can be an interface for fluid transmission, in particular for the transmission of a liquid, such as hydraulic oil, or a gas, such as compressed air. In this case, the work energy interface can comprise or be a fluid quick-release coupling known per se. Such a case can occur, for example, if at least one consumer is a hydraulic motor or a hydraulic piston-cylinder assembly commonly used in tillage machinery, for which the power arrangement supplies potential work energy in the form of a quantity of hydraulic fluid at a predetermined pressure level, usually exceeding the ambient atmospheric pressure.The same applies to the provision of potential work 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.

[0026] Similarly, energy used in work can be electrical energy, for example, when a consumer is an electrical device such as an electric motor, a data processing unit like a control unit, lighting, and the like. In this case, at least one energy interface can be an electrical interface, such as an electrical plug or socket. Multiple energy interfaces can each be designed as electrical interfaces to enable the use of electrical energy in different forms on the same tillage machine. Thus, electrical energy can be transmitted at different energy interfaces with different frequencies, including direct current, and / or with different voltages and / or with different currents.

[0027] In the case, which is more the rule than the exception, that several consumers operating according to different physical principles are provided on the processing machine, the soil cultivation 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 transferred from the force arrangement to the consumers.

[0028] The power assembly has a first support structure, separate from the machine frame, for connection to the chassis of the soil cultivation machine, in particular to the machine frame, via the first bearing interface. This first support structure has a first counter-bearing interface for the physical connection of the power assembly to the chassis of the soil cultivation machine, in particular to the machine frame, which is preferably detachable as intended.The first support device, acting as a kind of adapter or "form mediator" between the body of the soil cultivation machine on the one hand and power arrangements on the other, is an essential component that enables the quick and uncomplicated, yet permanent and safe arrangement of different power devices, especially those operating on different physical principles, on the body of the soil cultivation machine, particularly on the machine frame, during the manufacture of the soil cultivation machine.

[0029] To attach the power unit to the first support structure, the power unit has a power unit interface, and the first support structure has a power unit counterpart interface that is distinct from the first bearing counterpart interface. In embodiments of the invention, the power unit interface may not be directly connectable to the first bearing interface, for example, due to its shape and / or its connection locations. Regardless of which power unit is mounted on the first support structure, the first support structure, which carries the power unit, can always be connected to the chassis of the soil cultivation machine, in particular to the machine frame, by using the first bearing interface and the first bearing counterpart interface.If different force arrangements with different first support devices are provided for a soil cultivation machine, the mechanical connectability of the different force arrangements with and thus their storage capability on the body of the soil cultivation machine can be ensured by using a quasi-standardized connection between the first bearing interface and the first bearing counter interface.

[0030] 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, which can be coupled to the force device bearing formations, wherein the force device bearing formations and force device abutment formations are secured or can be secured against separation from one another in the coupled state, in particular by positive locking. Regarding the design of the force device bearing formations and abutment formations, what has been said above about the design of the first bearing interface and counter-interface applies accordingly, mutatis mutandis, and vice versa.

[0031] Thus, different primary support structures can be prepared for different power devices, the only design constraint of which is the formation or arrangement of a respective power device interface. The respective power device interface of a primary support structure is individually adapted to the power device to be supported and its power device interface.

[0032] Therefore, for a production set of components for manufacturing the soil cultivation machine, a plurality of different force arrangements can be provided, differing in their force device but only to a limited extent in their respective primary support devices. The primary support devices preferably differ only in their respective force device counterpart interface for attaching the respective force devices to them, since each force device will have its own force device bearing configurations in individually different shapes and / or at individually different locations.

[0033] Although not necessary, for reasons of simplified manufacturing and assembly, the first support devices of the different force arrangements of the production set provided for the manufacture of the soil cultivation machine are preferably designed and constructed identically, with the exception of the individual force device counter interface.

[0034] The advantage is obvious: by intermediately arranging the first support structure, a base-type soil cultivation machine without a power unit can always be designed essentially the same for the purpose of accommodating a power unit. Strictly speaking, this is also the case in the prior art, with the difference that only exactly one power unit without a first support structure fits onto and can be connected to the "base-type soil cultivation machine" prepared in this way. According to the present invention, however, the power unit, regardless of its type, can be quickly, easily, permanently, and securely connected to the machine frame of the base-type soil cultivation machine as a pre-assembled module via the connection between the first bearing interface and the first counter-bearing interface. In contrast, the base-type soil cultivation machine preferably has no interface on the machine frame side for directly accommodating the power unit.

[0035] Since the first support interface and the first support counter interface are interface formations for connecting three-dimensional bodies, both the first support interface and the first support counter interface preferably comprise a plurality of cooperating and preferably complementary connection formations.

[0036] For reasons of increased strength and rigidity, the first bearing interface and the first opposing bearing interface are preferably designed for a direct connection to each other, preferably one that is detachable as intended. However, a modular design of the soil cultivation machine may alternatively require that the first bearing interface and the first opposing bearing interface be designed for an indirect connection, preferably one that is detachable as intended, via an intermediate force transmission device, wherein the force transmission device is different from the first support structure. The prefix "force-" is intended only to indicate that the transmission device serves to define the force arrangement on the machine frame.The mediating device can be an adapter that can be connected to the first bearing interface on one functional side and to the first bearing counterpart interface on the other functional side. Such a force mediation 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.

[0037] In order to control the force arrangement to the necessary extent during operation and / or to detect and process the states and operating conditions of the force arrangement by the control device, the force arrangement can include a first signal interface. This first signal interface is designed to establish a signal-transmitting signal coupling with the first signal interface as part of the first signal connection, preferably one that is detachable as intended. Preferably, the first signal interface and the first signal interface can be connected to each other without tools, for example, by creating a plug connection. Preferably, the first signal interface and the first signal interface are designed with physically complementary electrical contacts, such as a plug and socket or a contact shoe and contact tongue, and the like.The first signal interface and the first signal counterpart interface can each be implemented by a single interface body, ensuring particularly fast and easy connectivity. However, the first signal interface and the first signal counterpart interface can also be formed by multiple separately connectable interface sub-bodies, for example, if signals from the force arrangement need to be transmitted to different locations on the machine frame and / or via different lines, and / or if the available installation space is insufficient for a single interface body.

[0038] Unwanted disconnection of the established plug connection between the first signal interface and the first corresponding signal interface can be prevented by a positive locking mechanism connecting the bodies carrying the respective contacts. Therefore, one interface, consisting of the first signal interface and the first corresponding signal interface, can have a locking configuration, and the other interface can have a locking counter-configuration that positively interacts with the locking configuration.

[0039] The first signal-to-reverse interface can be connected to at least one sensor and / or a local control unit of the force device and / or at least one actuator on the force device for signal and / or data transmission.

[0040] To output the required work energy, the force arrangement can comprise at least one work energy counterpart interface, which is configured to establish the work energy transfer connection with the at least one work energy interface, preferably one that is detachable as intended. At least one work energy counterpart interface of the at least one work energy counterpart interface can be configured for direct connection with at least one work energy interface of the at least one work energy interface, and / or at least one work energy counterpart interface of the at least one work energy interface can be configured for indirect connection with at least one work energy interface of the at least one work energy interface via an intermediate transmission device.Such a transmission device can, for example, be a gearbox or linkage that connects a mechanical energy-output interface with a mechanical energy-receiving interface. In the case of providing potential energy in the form of a fluid quantity at a predetermined pressure level, in particular a quantity of hydraulic fluid, a transmission device can be implemented by a fluidic conduit arrangement, in particular a hose and / or pipe arrangement. In the case of providing electrical energy, a transmission device can be an electrical conduit arrangement, optionally including electrical circuits, such as a transformer for changing the electrical voltage and / or an inverter for generating and / or changing the frequency of an electrical current provided as energy.A possible objection, that electric current and electrical energy are different entities, is only theoretically valid in this case and irrelevant to the soil cultivation machine under consideration. This is because electrical energy is used to perform work by the working device and is therefore provided as electrical energy per unit of time, consequently as electrical power. Electrical power is the product of an electrical voltage and the current flowing at that voltage. When using an inverter, both the supplied electrical voltage and the resulting current flow have a frequency. It should be noted that alternating current (AC) is primarily required in soil cultivation machines to power AC or three-phase motors, while other electrical consumers, such as those in vehicles, are generally operated with direct current (DC).

[0041] 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 benefit. Since the required work energy is not readily available in the necessary quantity as mechanical energy, and often not easily stored in other energy forms, the power system preferably includes at least one energy converter machine that converts the operating energy of one energy form into work energy of another energy form at its output. The power system can comprise an internal combustion engine and / or an electric motor and / or a fluid motor, particularly a hydraulic motor, as the energy converter machine. In this case, the energy converter machine directly outputs mechanical energy at a moving output element, such as a rotating output shaft.The mechanical energy output by the energy converter machine can be directly work energy and / or can be converted into another form of energy before being supplied to a consumer, as will be explained below.

[0042] According to the invention, the soil cultivation machine has a power supply arrangement with at least one power supply unit for supplying the power unit 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 operating locations can make the provision of different power supply units for arrangement on the body of the soil cultivation machine advantageous.

[0043] As explained at the outset, according to the invention, the soil cultivation machine is designed to be modular with regard to its energy supply arrangement as its energy source.

[0044] The basic concept of modularity in the present invention comprises the fundamental structure of a functional arrangement consisting of a functional device and a support structure that carries the functional device. For example, the force arrangement described above is structured as a functional arrangement.

[0045] Accordingly, the energy supply arrangement according to the invention has, as a further possible functional arrangement of the soil cultivation device discussed here: the energy supply device, a second support device separately designed from the machine frame, wherein the second support device carries the energy supply device, and an operational energy counterpart interface, which is designed to create an operational energy coupling with an operational energy interface, preferably detachable as intended.

[0046] The second support structure serves to simplify the use of different power supply arrangements on one and the same hull-type soil cultivation machine.

[0047] The second support structure comprises a second bearing interface, which is designed for the physical fixing of the second support structure to a second bearing interface, preferably in a releasable manner. The second support structure also preferably comprises a power supply interface with one or more power supply abutment formations for physical connection to a power supply interface of the respective power supply unit, in order to fix the power supply unit to the second support structure. The power supply interface can comprise at least one power supply bearing formation, which is physically connectable to the at least one power supply abutment formation of the power supply interface.Of the possible multiple power supply arrangements of a aforementioned production set, preferably all second support structures each have at least the same second bearing interface. However, the second support structures of the production set are expected to have different power supply interfaces adapted to the respective power supply unit to be mounted on them.

[0048] Therefore, a number of different power supply arrangements can be provided for a production set of components for manufacturing the soil cultivation machine, differing only in their power supply device. Although the second support structures can be designed differently, as long as they only have the second bearing interface, to facilitate manufacturing and assembly, the second support structures are preferably essentially identical in design and preferably differ only in their respective power supply device interfaces, since each power supply device will have its own power supply device interface at individually different bearing locations.Once a power supply unit is fixed to a second support structure, the specific design of the power supply unit's counterpart interfaces no longer matters for the further assembly of the resulting power supply arrangement on the chassis of the soil processing machine.

[0049] According to a preferred embodiment of the invention, and in fundamental agreement with what has been said above for the first bearing interface, the following applies in particular to the second bearing interface and the second bearing counter-interface: that the second bearing interface and the second bearing counter-interface can be designed for a direct connection to each other, preferably detachable as intended, or that the second bearing interface and the second bearing counter-interface can be designed for an indirect connection, preferably detachable as intended, with at least one power supply switching device in between, wherein the power supply switching device is different from the second support device.

[0050] Again, the addition of "energy supply" merely indicates the assignment of the aforementioned intermediary to the energy supply order. Otherwise, the provisions stated in the present application for the power intermediary apply to the energy supply intermediary.

[0051] The second bearing interface can be located directly on the machine frame.

[0052] The second support structure can be the aforementioned power transmission device and can therefore support the power assembly in addition to the power supply device. Alternatively, the second support structure can be fixed to the first support structure, allowing the power supply assembly to be mounted onto the first support structure as a pre-assembled module. In the latter case, the first support structure supports both the power assembly and the power supply assembly. Finally, the first support structure can also be the second support structure. In this case, the first support structure supports both the power assembly and the power supply device. In all the aforementioned embodiments, the first bearing interface is also the second bearing interface.In the first two cases, the force assembly and the power supply assembly, despite their respective modular designs, can be arranged as a pre-assembled, higher-level functional module on the machine frame. In the third case, the force assembly, the power supply assembly, and the first support structure also form a pre-assembled functional module. This allows for optimal use of the installation space provided or reserved for functional modules on the machine frame, as the individual allocation of the available installation space to the force assembly and the power supply assembly can be carried out on the support structure that directly carries a functional unit and a functional assembly.

[0053] Alternatively, the first and second bearing interfaces can be located separately in different areas of the machine body, particularly on the machine frame. In this case, the force arrangement and the power supply arrangement can be independently configured directly on the machine body, particularly on the machine frame.

[0054] The statements made in the present application regarding the possible design of the first storage interface apply mutatis mutandis to the second storage interface accordingly.

[0055] The operating energy interface is designed to establish an operating energy connection, preferably detachable as intended, between the power supply unit and the power unit, and is arranged on the power unit. The operating energy interface can be located on the first support structure or on the power unit. The operating energy can be electrical energy, so that the operating energy interface and the corresponding operating energy interface can each have electrically matched contacts physically designed to establish an electrical connection. The electrical contacts, which are dimensioned according to the expected electrical power to be transmitted, can be physically complementary as male and female contacts. The operating energy interface and the corresponding operating energy interface can be designed as a plug and socket.

[0056] As already explained above in connection with the first signal interface and the first signal counterpart interface, the operating energy interface and the operating energy counterpart interface, as well as any other interface-counter interface combination of the present invention that transmits a fluid or electric current, can also be secured against unwanted separation from each other, in particular by means of positive locking.

[0057] The operational energy can be energy stored in fluid fuels, i.e., liquid and / or gaseous fuels. The operational energy interface and the operational energy counterpart interface can then be complementary coupling sections of a fluidic quick coupling to form a fluid line.

[0058] While less preferred than generally possible, the operational energy can be provided as the potential energy of a fluid volume under increased pressure. Even in this case, the operational energy interface and the operational energy counterpart interface for forming a fluid line can be complementary coupling sections of a fluidic quick coupling.

[0059] To provide operational energy, the energy supply facility may include 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 wiring arrangement for connection to an external power source.

[0060] This list is expressly not exhaustive.

[0061] 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 quantity of fluid under increased pressure, in particular a quantity of hydraulic fluid. The fluid pump mentioned can be a gas compressor or a hydraulic pump. A hydraulic pump is preferred because of the high compressibility of gas compared to hydraulic fluid. Variant a. can be combined with a variant from b., c., and g.

[0062] In order to control the power supply arrangement to the necessary extent during operation, and / or to detect and process the states and operating conditions of the power supply arrangement, the power supply arrangement can include a second signal interface. This second interface is designed to establish a signal-transmitting connection, preferably detachable, with a second signal interface provided on the chassis of the soil cultivation machine and connected to the control unit. Preferably, the second signal interface and the second signal interface can be connected to each other without tools, for example, by creating a plug connection.What has been said above regarding the design of the first signal interface and the first signal counterpart interface, including their interlocking capability as protection against unwanted disconnection, applies mutatis mutandis to the second signal interface and the second signal counterpart interface accordingly.

[0063] In many cases, the energy input interface of a consumer, particularly of multiple consumers, is too far removed from the energy input interface of the power assembly to allow for a direct energy transfer connection. Therefore, the tillage machine can incorporate a transmission arrangement to connect the energy input interface and the energy input interface. This transmission arrangement is then located in or on the tillage machine to establish at least one section of the energy connection. Preferably, the transmission arrangement includes at least one mechanical output.

[0064] Preferably, a mechanical output of the at least one mechanical output is connected or connectable to the working device for transmitting torque via a mechanical transmission energy connection as part of the 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 form of energy. Preferably, the energy of the energy form converted by the at least one energy converter is transferable as work energy via a fluidic and / or electrical transmission energy connection as part of the energy connection to the at least one consumer.According to a preferred embodiment of the invention, the energy converter connected to the at least one mechanical output of the transmission arrangement may comprise or be a fluid pump, in particular a hydraulic pump, for generating a fluid flow, in particular a hydraulic flow, and / or a fluid pressure level, in particular a hydraulic pressure level, and / or the energy converter may comprise or be an electric generator.

[0065] A transmission energy connection is an energy connection where the suffix "transmission" merely indicates that the energy connection is associated with the transmission arrangement and serves the energy-transferring connection of the transmission arrangement to at least one consumer. A mechanical transmission energy connection can comprise or be a drive belt and / or a gear and / or linkage. A fluidic transmission energy connection can comprise or be at least one fluid line, in particular a fluid hose and / or fluid tube. An electrical transmission energy connection can comprise or be at least one electrical line.

[0066] Although the power device, as described above, can output potential energy as work energy, it preferably comprises a thermal or electrical power machine and outputs mechanical energy as work energy. The work energy output interface preferably has an output shaft or hub for outputting the mechanical work energy. The transmission device can have an input shaft or hub configured for connection to the work energy output interface. The transmission device can have an output shaft or hub configured for connection to the work energy interface.

[0067] The transmission arrangement can comprise a distribution gearbox with an input shaft and at least one output shaft, or more generally, a tap point, preferably with a plurality of output shafts, for energy or power that can be drawn from the output side of the transmission arrangement. The transmission arrangement can, in particular, comprise a so-called pump distribution gearbox, which has at least one auxiliary output, preferably several auxiliary outputs, to which a hydraulic pump is connected for driving the distribution gearbox. However, at least one hydraulic pump can be replaced, if necessary, by an electric generator and / or a gas compressor if there is a corresponding demand for electrical current or compressed gas at the tillage machine.Furthermore, the pump distribution gearbox preferably has a main mechanical output, which makes the mechanical power input to the pump distribution gearbox available at the output side. This main mechanical output is preferably coupled to the working unit, in particular to its power input interface, for force and / or torque transmission. The main output is generally the output of the distribution gearbox with the highest power output. The main output and auxiliary outputs, or the main drive and auxiliary drives, typically also differ in their transmission ratio from the input to the output side. This ratio is generally closer to 1 for the main output than for the auxiliary outputs, and vice versa.

[0068] In order to control the transmission arrangement to the necessary extent during operation, and / or to detect and process the states and operating states of the transmission arrangement, the transmission arrangement can include a third signal interface. This third interface is designed to establish a signal-transmitting connection, preferably detachable, with a third signal interface provided on the chassis of the soil cultivation machine and connected to the control unit. Preferably, the third signal interface and the third signal interface can be connected to each other without tools, for example, by creating a plug connection.What has been said above regarding the design of the first signal interface and the first signal counterpart interface applies, including their interlocking capability as protection against unwanted disconnection, mutatis mutandis, to the third signal interface and the third signal counterpart interface.

[0069] Since a soil cultivation machine under discussion typically has not just several consumers, but several consumers operating according to different physical principles, such as electric motors for drive systems 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 drive system uses hydraulic motors or electric motors.Fluidic actuators can be, for example, piston-cylinder arrangements, which serve as steering actuators for steering the front and / or rear axle tracks or as lifting arrangements for raising and lowering components, such as the roof of the operator's station and the like.

[0070] As already indicated above, the transmission arrangement can generally include a transmission device, the transmission device comprising: an input-side coupling formation for the, preferably detachable, energy-transferring coupling with the energy-transferring interface, and at least one output-side coupling formation for the, preferably detachable, energy-transferring coupling with the at least one energy-transferring interface.

[0071] The above statements regarding the power supply system also apply, mutatis mutandis, to the transmission system: in principle, without utilizing a modular design, the transmission system can be rigidly mounted to the machine frame without a support structure, using individual fastening points and means. A transmission system interface with bearing configurations on the transmission system is then directly physically connected to individually designed, matching abutment configurations on the machine frame. In this case, the transmission system is the transmission arrangement.

[0072] However, the use of different force configurations on otherwise essentially identical body-type soil cultivation machines can necessitate, or at least make advantageous, the use of different transmission configurations. A third support device can serve to facilitate the use of different transmission configurations.

[0073] Therefore, according to a preferred embodiment, the transmission arrangement comprises a third support structure which supports the transmission device, wherein the third support structure includes a third bearing interface designed for a physical connection, preferably releasable, between the third support structure and a third bearing interface. The third support structure preferably also includes a transmission device 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 structure.

[0074] Therefore, a number of different transmission arrangements can be provided for a production set of components for manufacturing the soil cultivation machine, differing 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, to facilitate manufacturing and assembly, the third support devices are preferably of essentially the same construction and preferably differ only in their respective transmission device abutment points, since each transmission device will have its own transmission device bearing points in individually different locations.Once a transmission device is fixed to a third support device, the specific design of the transmission device's counterpart interfaces no longer matters for the further assembly of the transmission arrangement thus formed on the chassis soil processing machine.

[0075] For the third storage interface and the third storage counter-interface, the following preferably applies: that the third bearing interface and the third bearing counter-interface are designed for a direct connection to each other, preferably detachable as intended, or that the third bearing interface and the third bearing counter-interface are designed for an indirect connection, preferably detachable as intended, with at least one transmission switching device in between, wherein the transmission switching device is different from the third support device.

[0076] The statements made in the present application regarding the possible design of the first and second storage interfaces apply mutatis mutandis to the third storage interface accordingly.

[0077] The present invention also relates to a manufacturing kit for a self-propelled soil cultivation machine according to claim 13. The manufacturing kit is described and further detailed above. The manufacturing kit includes, among other things: A body-type soil cultivation machine comprising a machine base with a machine frame, a drive system as a first consumer of the soil cultivation machine, a chassis with a plurality of running gear that can roll on a surface, wherein the chassis supports the machine frame standing on the surface, wherein at least one running gear can be driven by the drive system, a working device as a second consumer of the soil cultivation machine, wherein the working device has a working tool designed for soil cultivation, an operator's station as a workplace for a machine operator operating the soil cultivation machine, and a control device for controlling the operation of the soil cultivation machine, the first bearing interface, the first signal interface and the at least one working energy interface. the manufacturing kit additionally includes: a plurality of force arrangements as described and further developed above, wherein the force devices of at least two force arrangements provide work energy on the basis of different physical operating principles.

[0078] Further developments of this manufacturing set are described in the above description in connection with the provision of a plurality of different power supply arrangements and / or in connection with the provision of a plurality of different transmission arrangements.

[0079] Each support structure from the aforementioned first, second, and third support structures may include a support frame or support structure that absorbs the weight of the functional equipment and / or arrangement supported by the respective support structure. To reduce weight without significant loss of load-bearing capacity, the support frame or support structure may be a truss frame or truss structure, preferably comprising struts and connecting nodes. A truss structure of a support structure may be designed to be disassembled or may be permanently joined, for example, by welding and / or riveting. A support structure may be designed as a single unit or in multiple 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.

[0080] 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 storage device. In The data storage device can contain an operating program with control commands executable by at least one integrated circuit. Furthermore, the data storage device can be used to store operating data during the operation of the tillage machine.

[0081] The present invention will be explained in more detail below with reference to the accompanying drawings. It illustrates: Fig. 1 a rough schematic side view of a first part of a first embodiment of a manufacturing set according to the invention and a self-propelled soil cultivation machine formed therefrom, comprising a body soil cultivation machine, a first force arrangement, a first energy supply arrangement and a first transmission arrangement, Fig. 2 a rough schematic side view of a second part of the first embodiment of the manufacturing set according to the invention, comprising a second force arrangement, a second and a third energy supply arrangement, a second transmission arrangement, as well as a first and a second support device in stand-alone positions, and Fig. 3 a rough schematic partial view of a second embodiment of the soil cultivation machine and the manufacturing set according to the present application.

[0082] The Figure 1 and 2The figures show, by way of example, a section of a first embodiment of a manufacturing set 8 according to the invention for the production of a self-propelled soil cultivation machine 10 in the form of a large soil or road milling machine.

[0083] The viewer of Figure 1 looks at a soil cultivation machine 10 or simply "machine" 10, which is manufactured from components of the production set 8, in the direction of the drawing plane of Figure 1 orthogonal machine transverse direction Q. A machine longitudinal direction orthogonal to the machine transverse direction Q is denoted by L and runs parallel to the drawing plane of Figure 1 A machine height direction H also runs parallel to the drawing plane. Figure 1 and orthogonal to the machine's longitudinal direction L and to the machine's transverse direction Q. The arrowhead of the machine's longitudinal direction L in Figure 1Points in the forward direction. The machine's vertical direction H runs parallel to the yaw axis Gi of machine 10, the machine's longitudinal direction L runs parallel to the roll axis Ro, and the machine's transverse direction Q runs parallel to the pitch axis Ni.

[0084] The self-propelled soil cultivation machine 10 includes a body soil cultivation machine 11 as a machine base.

[0085] The base soil cultivation 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 base soil cultivation machine 11 that are connected to the machine frame 12 and may be movable relative to it.

[0086] The machine body 14, the number of components of which increases during the assembly of the self-propelled soil cultivation machine 10, comprises front hydraulic lifting columns 16 and rear hydraulic lifting columns 18 on the body of the soil cultivation machine 11, which are connected at one end to the machine frame 12 and at the other end to front tracks 20 and rear tracks 22 respectively.

[0087] In the side view of Figure 1 It is not apparent that the machine 10 has two lifting columns 16 and 18 respectively, each with an associated drive 20 and 22, at both its front and rear ends. The front lifting columns 16 and the rear lifting columns 18 are coupled to the drives 20 and 22, respectively, in a manner known per se by means of a drive connection structure 24, such as a connecting fork spanning the respective drive 20 or 22 in the transverse direction Q of the machine.

[0088] The tracks 20 and 22 are shown as exemplary track systems. In the illustrated embodiment, they are essentially identical in construction and form the chassis 26 of the machine 10 and the hull-mounted soil cultivation machine 11. Alternatively, one or all of the tracks 20 and / or 22 can also be wheeled tracks. Each of the tracks 20 and 22 is driven by a motor, in the illustrated embodiment by a hydraulic motor 28.

[0089] In the illustrated embodiment, the running gear 20 and the running gear 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 circulating track 32 (labeled only on the front running gear 20) is arranged and guided for rotation. The inner guide structure is tiltable about a tilting axis parallel to the pitching axis Ni and connected to the running gear connection structure 24.

[0090] The distance of the machine frame 12 from the running gear 20 and 22 can be changed by the hydraulic lifting columns 16 and 18.

[0091] The soil cultivation machine 10 or the body soil cultivation machine 11 has a driver's platform 34 from which a machine operator can control the machine 10 via a control panel 36 with a control device 38 included therein.

[0092] A working device 40 is arranged beneath the machine frame 12, here exemplified as a milling device 40 with a milling drum 44, which is housed in a milling drum box 42 and serves as a working tool of the working device 40. The milling drum 44 is rotatable about a milling axis R extending transversely Q to the machine, in order to remove subsoil material during soil cultivation, starting from the contact surface AO of the subsoil U, to 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 means of the lifting columns 16 and 18 therefore also serves to adjust the milling or, more generally, the working depth of the machine 10 during soil cultivation. Alternatively or additionally, the milling drum 44 can be mounted on the machine frame 12 in a height-adjustable manner relative to the machine frame 12.

[0093] For the in Figure 1In the large road milling machine shown, the arrangement of the milling unit 40 in the longitudinal direction L of the machine between the front and rear tracks 20 and 22, respectively, is typical. Such large milling machines, as well as soil removal machines in general, can have a conveyor belt to transport the removed soil material away from the machine 10. A conveyor belt, which is also generally present on the machine 10, is shown here for the sake of clarity. Figure 1 not shown.

[0094] 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.

[0095] The operator's cab 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 so that it can be raised and lowered by means of a movement guide 52 and a hydraulic drive 54. Figure 1 The protective roof 50 is shown in its raised operating position, in which the machine 10 is ready for soil cultivation operation.

[0096] A first power arrangement 56 is arranged on the base of the soil cultivation machine 11 to form the soil cultivation machine 10. The base of the soil cultivation machine 11 receives a power arrangement as a central power plant of the machine 10, which provides essentially all of the work output of the machine 10.

[0097] The first power arrangement 56 comprises an internal combustion engine 58 as a first power unit and a first support unit 60. For further explanation of the design of the support unit 60, reference is made to... Figure 2 referred to where it is shown in isolation.

[0098] The floor-mounted soil cultivation machine 11 has a first bearing interface 62 on the machine frame 12 or on the machine body 14, at which the first support device 60 is fixed by a first corresponding bearing interface 64 arranged on the first support device 60. In the illustrated embodiment, the first bearing interface 62 is symbolized by three coupling elements 62a, to which three corresponding coupling elements 64a of the corresponding bearing interface 64 of the first support device 60 are coupled. For particular positional stability of the arrangement of the first support device 60 on the machine frame 12, the coupling elements 62a and the corresponding coupling elements 64a are designed to be complementary. The coupling elements 62a and the corresponding coupling elements 64a can be fixed to one another by threaded engagement or by other engagement.

[0099] For the sake of clarity, 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 in Figure 2 marked.

[0100] The first bearing counter-interface 64 is arranged on the functional side 60a of the first support device 60, which is associated with the machine frame 12. In this case, the functional side 60a is also a physical side of the first support device 60.

[0101] The internal combustion engine 58 is arranged on the functional side 60b of the first support structure 60, opposite the functional side 60a. For this purpose, the first support structure 60 has a power unit interface 66 on its functional side 60b, which is also a physical side of the first support structure 60. The internal combustion engine 58 is mounted to this interface by means of its power unit interface 68. The power unit interface 68 and the power unit interface 66 can be configured like a known engine mount for mounting an internal combustion engine in a vehicle frame.

[0102] In Figure 1 The power device counter-interface 66 is symbolized by two power device abutment formations 66a. The power device interface 68 is symbolized by two power device bearing formations 68a.

[0103] On the functional side 60b associated with the functional devices, a pump distribution gearbox 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 introductory description, has a transmission device counterpart interface 72 on its functional side 60b, symbolized by two transmission device abutment formations 72a.

[0104] The pump distributor gearbox 70, with its transmission device interface 74, is mounted at the transmission device counterpart interface 72 in a manner known per se. The transmission device interface 74 is symbolized by two transmission device bearing formations 74a, of which in Figure 1 For the sake of clarity, only the rights are marked with a reference symbol.

[0105] The pump distribution gearbox 70 and the first or third support device 60 form a transmission arrangement 76.

[0106] The internal combustion engine 58, for example a diesel combustion engine, has as an output element for the output of work performance or work energy an orthogonal to the drawing plane of Figure 1 The output shaft 78 acts as a working energy counter-interface, which in the operational state is coupled to an input hub 80 of the pump distributor gearbox 70 in a torque-transmitting manner.

[0107] The pump distribution gearbox 70 has a pulley 82 as its first mechanical output, which is driven by a Figure 1The only indicated drive belt 83 can be completed with a pulley 84 coupled to the milling drum 44 for torque transmission, forming 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 the rotational speed of the pulley 84 relative to the milling drum 44 by a certain transmission ratio and increases the torque by the inverse transmission ratio. Since the gear-side pulley 82 transmits the working energy necessary for the operation of the milling device 40, the gear-side pulley 82 forms the main output of the pump distribution gearbox 70.

[0108] A hydraulic pump 86 is arranged on a further output, more precisely on a secondary output of the pump distribution gearbox 70. During its operation, this pump delivers hydraulic fluid at an increased pressure level as fluidic energy via a quick-release coupling 88. The fluidic energy of the hydraulic pump 86 can be used by the hydraulic motors 28 for propelling the tillage machine 10, by the hydraulic drive 54 of the protective roof 48 for raising and lowering the protective roof 50, and by the steering mechanism 46 for steering the front lifting columns 16 and / or the rear lifting columns 18. The hydraulic pump 86 can raise the pressure of the hydraulic fluid present at the tillage machine 10 via the quick-release coupling 88.

[0109] 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 with the control unit 38 of the ground cultivation machine 11 or the ground cultivation machine 10, the ground cultivation machine 11 has a first signal interface 92, to which a first signal interface 94 of the internal combustion engine 58 can be coupled for data and signal transmission. The interface between the first signal interface 92 and the first signal interface 94 can be a plug, and the other interface can be a corresponding socket.

[0110] To supply fuel as a source of operating energy for the operation of the internal combustion engine 58, the internal combustion engine 58 preferably has a quick-coupling assembly 96 as an operating energy interface through which fuel can be supplied to the internal combustion engine 58.

[0111] To ensure the continuous operation of the internal combustion engine 58, a power supply arrangement 98 is provided on the chassis of the soil cultivation machine 11. The power supply arrangement 98 provides the internal combustion engine 58 with operating energy, i.e., in this case, fuel, during its operation.

[0112] The energy supply arrangement 98 is modular in design and comprises a tank 100 as the energy supply unit and a second support structure 102 for mounting on the machine frame 12 of the base tillage machine 11 or the tillage machine 10. The tank 100 contains a quantity of fuel which can be supplied to the internal combustion engine 58 via a fuel delivery line 104, which serves as an operating energy line and as part of an operating energy connection 106. The fuel delivery line 104 carries a quick-release coupling 108 as an operating energy interface, which can be quickly and tool-free connected to the quick-release coupling 96 on the internal combustion engine side to form the operating energy connection 106. In the coupled, fluid-transferring state, the quick-release coupling 96 and the quick-release coupling 108 form an operating energy coupling.

[0113] A pumping module 110 can be arranged in the fuel tank 100, which can be controlled by the control unit 38. For this purpose, the fuel tank 100 has a second signal interface 112, which is connected to a Fig. 1 The second signal interface 122, not shown, on the side of the hull soil processing machine 11 can be coupled for the transmission of signals and data (see. Figure 2 The second signal interface 122 can be designed like the first signal interface 92.

[0114] The fuel tank 100, as an energy supply unit for the tillage machine 10, has an individual energy supply unit interface 114, by means of which it is fixed to an equally individual energy supply unit counterpart interface 116 of the second support unit 102. The energy supply unit interface 114 has a plurality of energy supply unit bearing formations 114a, which are represented only symbolically. Each of these bearing formations is coupled to a complementary energy supply unit counter-bearing formation 116a and physically fixed to it.

[0115] The power supply arrangement 98 is fixed to the machine frame 12 or machine body 14 via the second support device 102 at a second bearing interface 118 of the machine frame 12. The second support device 102 has a second corresponding bearing interface 120 for fixing to the second bearing interface 118. The second bearing interface 118 is located in Figure 1 represented by two symbolically depicted coupling formations 118a, the second bearing counter-interface 120 is in Figure 1 represented by two symbolically depicted complementary coupling counter-formations 120a.

[0116] The second bearing counter-interface 120 is arranged on the functional and physical side 102a of the second support device 102 facing the machine frame 12, the power supply device counter-interface 116 on the opposite functional and physical side 102b of the second support device 102 facing away from the machine frame 12.

[0117] The soil cultivation machine 10 can thus be built modularly with regard to its supply of working energy or working performance and adapted to the respective customer requirements or boundary conditions of the use.

[0118] In Figure 2 Further components of manufacturing set 8 are shown. These are essentially functionally identical arrangements, devices, interfaces, and formations as in... Figure 1 , which differ from those of Figure 1 are designed, are in Figure 2with identical, but apostrophized, reference symbols. For their explanation, explicit reference is made to the description already given for the respective reference symbols. Figure 1 Reference is made to the above unless additional information is explicitly provided.

[0119] In Figure 2The section with the bearing interfaces 62 and 118 of the body-mounted soil cultivation machine 11 is shown in the lower left. Also shown there is a second signal interface 122 for the possible signal and data transmission connection of the power supply arrangement 98, also in configuration 98' or 98", with the control unit 38, as well as a third signal interface 124 for the possible signal and data transmission connection of the transmission arrangement 76, also in configuration 76', with the control unit 38. The power supply arrangement 98 to be connected, optionally in configuration 98' or 98", then has a corresponding second signal interface 112, and the transmission arrangement 76 to be connected, optionally in configuration 76', has a corresponding third signal interface 126.

[0120] Thus, in deviation from the transfer order 76, the Figure 1Another transmission arrangement 76', again as a pump distribution gearbox 70', is not fixed to the first support device 60 and also not to a separate third support device, but is directly mounted on machine frame 12 via corresponding transmission device bearing formations 74a' and abutment formations 72a'.

[0121] The pulley 82 on the output side of the pump distribution gearbox 70' remains unchanged, as does the pulley 84, which serves as the working energy interface for the tillage machine. However, the pump distribution gearbox 70' has a Figure 2A total of four mechanical auxiliary drives, each with a hydraulic pump 86' driven by it, each of which has a fluidic quick-coupling assembly 88 for dispensing hydraulic fluid under increased pressure. For the sake of clarity, only the two rightmost hydraulic pumps 86' of the pump distribution gearbox 70' are labelled.

[0122] By using four hydraulic pumps 86', a local control unit 128 can be used to control the pump distribution gearbox 70' or, more generally, the transmission arrangement 76', which can be coupled to the third signal interface 124 via a third signal interface 126.

[0123] In Figure 2An alternative power arrangement 56' with an electric motor 58' as the power unit is also shown. The output shaft 78', as the working energy interface of the power arrangement 56' of the electric motor 58', can be connected to the input hub 80' of the pump distribution gearbox 70' in a torque-transmitting manner.

[0124] Unlike the first power arrangement 56 with the internal combustion engine 58, the alternative power arrangement 56' requires operating energy in the form of electrical energy. For this purpose, an alternative energy supply arrangement 98' is provided, which includes an accumulator 130 as an energy storage device. Accordingly, the operating energy interface 96' and the operating energy counterpart interface 108' are designed as quick-connect electrical components, such as a plug and socket. Electrical cables therefore connect the electric motor 58' and its energy supply, the accumulator 130.

[0125] In contrast to Figure 1 The power supply arrangement 98' is not directly connected to the machine frame 12 via the second support structure 102', but indirectly via the first support structure 60'. The first support structure 60' then also serves as the power supply intermediary. In this case, the bearing interface 64 functions as both the first and second bearing interface 64 and includes not only the coupling elements 64a, but also the coupling elements 64a'. The coupling elements 120a' of the second bearing interface are located on the second support structure 102'. When the force arrangement 56' and power supply arrangement 98', pre-assembled as a functional module, are arranged on the base soil cultivation machine 11, the coupling elements 62a and 118a form a common bearing interface of the functional module, which serves as both the first and second bearing interface.

[0126] The coupling counter-formations 64a and 120a are shown in the figures with different shapes only as examples to graphically support their distinguishability. In fact, the coupling counter-formations 64a and 120a can be designed with identical shapes. This is even preferable with regard to manufacturing effort. The described possible identical shape also applies to the coupling formations 62a and 118a, as well as to at least two abutment formations from the power device abutment formations 66a, the transmission device abutment formations 72a', and the power supply device abutment formations 116a, and to at least two bearing formations from the power device bearing formations 68a, the transmission device bearing formations 74a', and the power supply device bearing formations 114a.

[0127] Instead of the power supply arrangement 98' with the electric accumulator 130, a module of a power supply arrangement 98" with a fuel cell 132 and an associated fuel tank 100" for conversion into electrical energy in the fuel cell 132 can alternatively be used. A control unit 113 controlling the operation of the fuel cell 132 can be connected to the control unit 38 on the base soil cultivation machine 11 via the second signal interface 112'. Such a power supply arrangement 98" can also be prepared for mounting on a second support structure 102' for arrangement on the base soil cultivation machine 11. The second support structure 102' can be mounted, like that of the power supply arrangement 98', indirectly via the first support structure 60' or directly on the machine frame via a second bearing interface.

[0128] Likewise, the energy supply arrangement 98‴ with a cable drum 134 arranged on it with a line arrangement 136 for connection to a site-side power supply can be used as a module prepared on the soil cultivation machine 10.

[0129] Thus, due to the different arrangements available in the production set 8, the soil cultivation machine 10 can be equipped with different power machines and different energy supply arrangements for supplying operating energy, as well as different transmission arrangements, and configured for different operating conditions with relatively little effort.

[0130] The above example of different modules is merely illustrative and not exhaustive.

[0131] In Fig. 3A second embodiment of a body-mounted soil cultivation machine, designed according to the basic concept of the present invention, is shown and designated 1011. Likewise, a second embodiment of the manufacturing kit, designed according to the basic concept of the present invention, is shown and designated 1008. The arrangement of one of the various power supply arrangements 1098', 1098" or 1098‴ shown at the second bearing interface 1118 completes the body-mounted soil cultivation machine and constitutes a second embodiment of a self-propelled soil cultivation machine.

[0132] Identical and functionally equivalent arrangements, devices, components and component sections as in the corresponding first embodiments. Figure 1 and 2 are in Figure 3 with the same reference numbers, but increased by the number 1000.

[0133] The second embodiments of the soil cultivation machine or body soil cultivation machine 1011 and assembly kit 1008 will only be described below insofar as they differ from the corresponding first embodiments of the Figure 1 and 2 to distinguish, whose description also serves to explain Figure 3 This applies unless otherwise stated below. The description of the Figure 1 and 2 is therefore also used to explain Figure 3 expressly referred to.

[0134] The essential difference between the body-mounted soil cultivation machine 11 of the first embodiment and the body-mounted soil cultivation machine 1011 is that the power assembly 1056' with the electric motor 1058' as the power unit, as well as the transmission assembly 1076' in the exemplary form of the pump distribution gearbox 1070', are directly and rigidly connected to the machine frame 1012 via corresponding bearing and abutment configurations. The power assembly 1056' and the transmission assembly 1076' are thus part of the body-mounted soil cultivation machine 1011.

[0135] The energy supply arrangements 1098', 1098" and 1098‴ alone can be connected to the body-level soil processing machine 1011, preferably detachably, via a second bearing interface 1118 and a second bearing counter-interface 1120 of a second support device 1102 or 1102' that is preferably complementary to this second bearing interface 1120.

[0136] Since the second support device 1102 or 1102' is 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' have Figure 3 the same second storage counter-interface 1120. The one in Figure 3 The only second support device 1102' is therefore apostrophized because, compared to the other second support devices 1102, it has a different power supply device counterpart interface 1116', which, however, is only intended to illustrate by way of example that a second support device can have any suitable power supply device counterpart interface on its functional side assigned to the power supply device.

[0137] The Figure 3only one power unit 1058' is shown. In fact, several partial power units can be arranged on the body soil cultivation 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.

[0138] This allows a soil cultivation machine to be individually equipped with the most suitable energy supply arrangement to meet specific requirements.
