Description

[0001] The present invention relates to the use of a drive system for a mobile device for separating and / or shredding feed material, in particular recycled material. The device can have a separating device and / or a shredding device for separating or shredding the feed material. Furthermore, the present invention also relates to a mobile device for separating and / or shredding feed material, in particular recycled material, having a separating device and / or a shredding device.

[0002] Drive systems for devices of the aforementioned type are generally known. In practice, a distinction is made between so-called "stationary" and "mobile" devices. Mobile devices are characterized not only by their location-based mobility but also by their ability to operate independently of the power grid. Stationary devices are specifically tied to a specific location and are not inherently mobile. Stationary devices are also powered by electrical energy supplied via the power grid. In principle, a stationary system could, of course, also be powered by a combustion engine. Stationary systems are specifically location-based systems that cannot simply move.

[0003] In the following, a distinction is made between network-connected, in particular stationary, and network-independent or off-network, in particular mobile, devices.

[0004] In practice, it has been found that both stationary and / or grid-connected and mobile and / or off-grid devices are generally required. For example, it is not possible to guarantee a connection to the power grid at every location where a device is used. Such devices are only used when needed. In recycling operations in particular, the devices are usually operated at a stationary and / or grid-connected location that ensures an energy supply via the power grid. At certain times or for certain purposes, however, this device should also be relocatable to other locations and therefore usable as a mobile and / or off-grid device. This is not possible with most devices known in practice, as they are designed either as stationary and / or grid-connected or as mobile and / or off-grid devices.

[0005] A few devices known from practice are known to be capable of being used both as stationary and / or grid-connected devices and as mobile and / or off-grid devices, meaning they can be powered via the power grid or via a motor that can be operated independently of the power grid. However, such devices are not designed for long-term use or continuous operation. The mobile and / or off-grid devices known from practice, both stationary and / or grid-connected and simultaneously comprise a multitude of individual electric drives for various device components. These drives are subject to high wear and tear under high loads and therefore require replacement relatively frequently.These electric drives are necessary due to the simultaneous design of the device as a mobile and / or grid-independent and stationary and / or grid-connected device in order to ensure a change from the power grid to a motor that can be operated independently of the power grid.

[0006] Due to the aforementioned problems, such devices are generally avoided because they are not suitable for long-term use. Therefore, in practice, it is common practice for a recycling facility to maintain a mobile and / or off-grid device for mobile and / or off-grid use in addition to a stationary and / or grid-connected device.

[0007] The object of the present invention is to avoid the aforementioned disadvantages of the prior art or at least to substantially reduce them.

[0008] The above object is achieved by the use of a drive system according to claim 1.

[0009] In the use according to the invention, it is provided that a drive system is used for a mobile and / or grid-free device comprising a separating device and / or a comminuting device for separating and / or comminuting feed material. The feed material is intended to be recycled material, in particular.

[0010] Grid-independent drive systems can also be referred to as grid-independent drive systems. In particular, a mobile drive system is envisaged.

[0011] The separation device can have at least one screening means, and the comminution device can have at least one comminution means. Various means are conceivable as screening means, such as spiral-shaft separators, flat-deck screens, and / or screen drums. Various means are also conceivable as comminution means, in particular comminution rollers.

[0012] According to the invention, it is further provided that the drive system has an electric motor, which can be connected to the power grid for power supply, for driving a drive means of the drive system, and an internal combustion engine, which is independent of the power grid, for selectively or alternatively driving the at least one drive means. A drive shaft is provided, in particular, as the drive means. In particular, the drive means or the plurality of drive means can be driven by the electric motor or the internal combustion engine. According to the invention, the drive system is designed such that the drive energy required to drive the drive means can be applied either by the electric motor or by the internal combustion engine. Furthermore, according to the invention, the drive means is coupled to at least one hydraulic pump of the drive system.

[0013] According to the invention, the aforementioned design ensures that the device can be operated both stationary and / or grid-connected, via the electric motor, and mobile and / or off-grid. Mobile and / or off-grid use of the device can be ensured by the internal combustion engine, which is independent of the power grid. The internal combustion engine requires a fuel, preferably diesel, as its drive energy. Other fuels are also conceivable, such as HVO 100 or hydrogen (H2).

[0014] A diesel engine is particularly preferred as the internal combustion engine. The fuel for driving the internal combustion engine, which is particularly self-sufficient, can be supplied independently of the power grid, which can ensure autonomous use of the device. Diesel engines are particularly characterized by their robustness.

[0015] The hydraulic pump, in turn, enables the separation device or shredding device to be hydraulically driven. Furthermore, hydraulic motors driven by the hydraulic pump can be used in the device. Energy efficiency is particularly high in this context, since the energy provided by the hydraulic pump can be used directly to drive the hydraulic motors. Unlike individual electric drives, hydraulic drives are characterized by high wear resistance.

[0016] Accordingly, according to the invention, a long-term use of a device that can be used both mobile and / or off-grid and stationary and / or on-grid can be ensured by the use of the drive system according to the invention.

[0017] The hydraulic pump used according to the invention is also advantageous because it eliminates the need for converting electrical energy into mechanical energy and, if necessary, for a subsequent conversion back into mechanical energy. The energy provided by the hydraulic pump can be used directly, resulting in high efficiency.

[0018] In a particularly preferred embodiment of the present invention, a control device is provided for selectively switching between the electric motor and the internal combustion engine, so that the drive energy required to drive the at least one drive means is provided either by the electric motor or the internal combustion engine. The control device can in particular be remotely controlled and preferably an external operator can control the control device, so that an external operator can also "switch" between the electric motor and the internal combustion engine. Accordingly, the control device makes it possible to directly influence the drive of the at least one drive means and to select the motor which is to provide the necessary energy depending on the operating situation. Accordingly, the device can in particular be switched from "grid-connected" or "stationary" to "mobile" or“off-grid” / “off-grid” or vice versa.

[0019] The hydraulic pump is preferably designed to directly drive a means of the separating device and / or a comminution means for comminution devices of the device or to drive at least one linear or rotary hydraulic motor of a screening means of the separating device or a comminution means of the comminution device of the device. Accordingly, the hydraulic pump can directly provide the required energy for the screening means or the comminution means. If necessary, the screening means or the comminution means is driven via a linear or rotary hydraulic motor, wherein the relevant hydraulic motor can be supplied with energy directly from the hydraulic pump. It is understood that further hydraulic pumps can also be provided, which in particular are not directly designed to drive the screening means of the separating device or the comminution means of the comminution device.their respective hydraulic motors are provided, but rather, as needed, to drive other means or devices of the device which, unlike the separating or comminuting device, are not in continuous operation. However, at least one hydraulic pump is preferably provided to directly drive the screening means or the comminuting means.

[0020] As previously explained, a plurality of hydraulic pumps can preferably be provided. A hydraulic pump can be designed as an adjustable and / or adjustable main hydraulic pump. The main hydraulic pump is preferably designed to directly drive the screening means or the comminution means or to drive the linear or rotary hydraulic motor of the screening means or the comminution means. In addition to the adjustable or adjustable main hydraulic pump, at least one further hydraulic pump can also be designed as a constant or adjustable secondary hydraulic pump. The secondary hydraulic pump preferably requires no adjustment and is particularly preferably a so-called "constant" pump. With a constant hydraulic pump, a continuous flow of hydraulic fluid is preferably provided, with a constant delivery rate being provided in particular for the secondary hydraulic pump.The hydraulic pumps can, in particular, be arranged side by side. Preferably, all hydraulic pumps are driven simultaneously by the drive means. In further embodiments, a plurality of drive means can also be provided for driving several hydraulic pumps, wherein each hydraulic pump can be assigned a drive means, but in particular, several hydraulic pumps can also be driven via one drive means.

[0021] In particular, the additional hydraulic pump, designed as a secondary hydraulic pump, can be configured to drive additional means of the separating device or the shredding device. These additional means can, in particular, be driven only on demand. Examples in this context include conveyor belts, alignment cylinders, or the folding function for conveyor belts, as they are only operated on demand. Furthermore, an on-demand drive can also be provided, for example, for other functions of the separating device or the shredding device, whereby the required working energy can be provided by the secondary hydraulic pumps.

[0022] In another particularly preferred embodiment of the present invention, hydraulic pumps are arranged one behind the other or in series on the drive means. In particular, the hydraulic pumps are designed to be sealed against one another, so that, in particular, no hydraulic fluid leaks out. As already explained, all hydraulic pumps can preferably be driven by a drive means, which is designed, in particular, as a drive shaft.

[0023] In another particularly preferred embodiment, the electric motor and / or the internal combustion engine are each connected and / or coupled to the at least one drive means via a connecting means. Only one motor, namely either the electric motor or the internal combustion engine, or both motors can be connected to the drive means via the connecting means. This also depends on whether both motors act directly or indirectly on the drive means. The connecting means enables, in particular, torque transmission from the electric motor or the internal combustion engine to the drive means and thus the drive of the drive means.

[0024] The connecting means is preferably designed as a belt. Corresponding pulleys for coupling to the belt can be provided on the electric motor and / or the internal combustion engine and / or the drive means, as will be explained below. In this embodiment, it is particularly preferred that the at least one drive means forms a belt transmission with the electric motor and / or the internal combustion engine. It is understood that a belt transmission can be formed between the electric motor and the drive means, or, if necessary, between the internal combustion engine and the drive means. Belt transmissions enable reliable power transmission between the respective motor and the drive means.

[0025] In a likewise preferred alternative, the connecting means is designed as a chain and / or traction means. In this embodiment, too, efficient torque transmission from the respective motor to the drive means can be ensured. In a further alternative, the connecting means is designed as a gear, in particular so that the at least one drive means forms a gear transmission with the electric motor or the internal combustion engine. Gear transmissions are particularly wear-resistant and enable reliable power transmission from the respective motor to the drive means. In this context, it is understood that the connecting means preferably provided for the electric motor and the internal combustion engine can also be designed differently or, if necessary, can be the same.Furthermore, a further alternative provides for the connecting means to be designed as a friction wheel, in particular so that the at least one drive means forms a friction gear with the electric motor and / or the combustion engine. Even with a friction gear, the torque transmission from the respective motor to the drive means can be ensured, while simultaneously ensuring long-term use.

[0026] Transmission means can be provided for coupling to the connecting means - however, these transmission means do not necessarily have to be present. In a particularly preferred embodiment, a transmission means for coupling to the connecting means is arranged on each of the electric motor and / or the internal combustion engine. The transmission means can in particular be designed as a pulley, gear and / or friction wheel, depending on the respective connecting means. The transmission means thus corresponds in particular to the connecting means. If the connecting means is designed as a belt, for example, the transmission means assigned to the electric motor and / or the internal combustion engine can in particular be designed as a pulley. However, if the respective connecting means is designed as a gear, it is advisable to also design the transmission means on the electric motor and / or the transmission means as a gear.The same applies to the design of the connecting element as a friction wheel.

[0027] In addition, a further transmission means for coupling with the connecting means can also be arranged on the drive means, in particular wherein the transmission means is designed as a pulley, gear wheel and / or friction wheel, in particular depending on the design of the respective connecting means, as has already been explained at the beginning in connection with the transmission means.

[0028] Thus, both the transmission means of the respective motor and the further transmission means associated with the drive means can be designed in such a way that coupling via the connecting means can be ensured.

[0029] In an alternative, likewise preferred embodiment, a transmission means is provided on the electric motor and / or the internal combustion engine for direct coupling to a further transmission means arranged on the drive means, preferably for torque transmission. In this embodiment, at least one connecting means, preferably both connecting means, can be omitted. It is particularly preferred that either the electric motor or the internal combustion engine is directly coupled to the drive means, and the respective other motor is coupled to the drive means via a connecting means.With direct coupling, it is provided that, in particular, the transmission means of the respective motor is arranged directly on the further transmission means associated with the drive means, so that, in particular, the respective motor—either the electric motor or the internal combustion engine—engages directly on the drive means. This embodiment ensures efficient power transmission from the respective motor to the drive means.

[0030] In the aforementioned embodiment, the transmission means is particularly preferably designed as a gear and / or friction wheel. Further embodiments that ensure a direct coupling of the transmission means to the further transmission means can be provided. If necessary, the further transmission means and the transmission means can also be omitted, particularly if either the electric motor or the internal combustion engine acts directly on the drive shaft.

[0031] In a further preferred embodiment, it is provided that the electric motor and the internal combustion engine can each be coupled to the at least one drive means via a coupling device and can be uncoupled from the at least one drive means, preferably to interrupt the torque transmission—i.e., to decouple. In particular, at least one coupling device is interposed between at least one further transmission means and the drive means. Alternatively or additionally, it can also be provided that at least one coupling device is interposed between at least one transmission means and the respective connecting means and / or the respective further transmission means.

[0032] The clutch device ensures that when switching between the combustion engine and the electric motor, the torque transmission of the no longer "active" motor can be interrupted, allowing the drive shaft to be driven only by the motor intended for the drive. The components connected to the "inactive" motor should then also no longer be moved, particularly to prevent damage to the device. This is ensured according to the invention by the clutch device, which enables, in particular, engagement and disengagement, thus enabling torque transmission as needed.

[0033] Particularly preferably, the coupling device is assigned at least one tensioning means associated with the electric motor and / or the internal combustion engine for releasing and tensioning a connecting means designed as a drag belt, and / or the coupling device comprises such a tensioning means. This embodiment is provided in particular when the connecting means on which the coupling device is intended to act is designed as a drag belt. In particular, when the drag belt is tensioned, the drive energy can be transferred to the drive means, while in the relaxed state, the electric motor or the internal combustion engine is decoupled from the drive means, particularly depending on whether this type of coupling device is provided for the electric motor or the connecting motor.

[0034] In a further alternative embodiment, the clutch device can comprise at least one clutch associated with the electric motor and / or the internal combustion engine, in particular a friction clutch and / or a dog clutch. This type of clutch also efficiently enables torque transmission between the respective motor and the drive means as needed, as well as decoupling in this regard.

[0035] Furthermore, in a further, particularly preferred embodiment of the inventive concept, it is provided that the clutch device has at least one freewheel. In particular, a freewheel can be interposed between at least one further transmission means and the drive motor means. Alternatively or additionally, it can be provided that at least one freewheel is interposed between at least one transmission means and the respective connecting means and / or the respective further transmission means. Preferably, one freewheel can be arranged on the drive means for the clutch to the electric motor and another freewheel can be arranged on the drive means for the clutch to the combustion engine. The freewheels efficiently enable coupling and decoupling to the respective motor as required. In this context, a freewheel can transmit torque in particular only in one direction of rotation.When the direction of rotation is reversed (or when the speed of the part actually being driven is greater than that of the driving part), the connection is automatically released. Various different freewheels are known in practice. One particularly well-known application of a freewheel is the hub of a bicycle. For example, the rear wheel continues to rotate when the pedal drive is operated more slowly, meaning the rear drive overtakes the drive or is stopped. As a result, in the case of a derailleur, the derailleur no longer rotates with the rear wheel, so that the chain is not thrown off due to the slow drive. Freewheels can be equipped with the following components, among others: clamping rollers, clamping bodies, pawls, claw rings and / or wrap springs.

[0036] According to the invention, the freewheel is designed in such a way that efficient decoupling can be ensured.

[0037] The aforementioned embodiments represent different possibilities for the arrangement and coupling of the respective motor to the drive means. Thus, the motors can be connected to the drive means via connecting means, or, if necessary, at least one motor can be connected directly to the drive means. This results in both the electric motor and the combustion engine being able to be connected or coupled to the drive means via a connecting means, each with a freewheel of the clutch device interposed, in particular such that two freewheels are arranged one behind the other on the drive means.

[0038] In a further embodiment, it can be provided that either the internal combustion engine or the electric motor is arranged directly on the drive means with the interposition of a freewheel to the clutch device - ie in particular in a line with the drive means - and the respective other motor (electric motor or internal combustion engine) is connected or coupled to the drive means via a connecting means with the interposition of a freewheel of the clutch device, in particular in such a way that two freewheels are arranged one inside the other.

[0039] Depending on whether the freewheels are arranged inside each other or one behind the other, the corresponding coupling or connection to the respective motor can be designed.

[0040] Furthermore, the present invention relates to a mobile and / or off-grid device for separating and / or comminuting feed material, in particular recycled material. The device according to the invention is provided with a separating device or a comminuting device. The separating device can have at least one screening means, or the comminuting device can have at least one comminuting means. In addition, the mobile and / or off-grid device also comprises a drive system. The drive system can have an electric motor, connectable to the power grid for power supply, for driving at least one drive means, in particular at least one drive shaft, of the drive system, and an internal combustion engine, in particular a diesel engine, independent of the power grid, for driving the at least one drive means.According to the invention, the drive system is designed such that the drive energy required to drive the drive means can be provided either by the electric motor or by the internal combustion engine. Furthermore, the invention provides that the drive means is coupled to at least one hydraulic pump of the drive system.

[0041] In this context, it is understood that the aforementioned design features of the drive system, as described in connection with the use of the drive system, are equally applicable to the mobile and / or off-grid device without the need for further explanation. Statements regarding the mobile and / or off-grid device can also be applied to the aforementioned use if necessary. In connection with preferred embodiments and advantages of the mobile and / or off-grid device, reference may therefore be made to the aforementioned statements.

[0046] The Fig. 1 shows a drive system 1 for a mobile and / or network-independent device 4, which is shown schematically in the Fig. 7 to 10. The Fig. 7 to 10 show that the mobile and / or off-grid device has either a separating device 2 or a comminuting device 3 and is therefore designed for separating or comminuting feed material, in particular recycling material. Not shown in detail is that the device described, among other things, in Fig. 1 shown drive system 1 is used for the device 4.

[0047] How Fig. 1 shows, the drive system 1 has an electric motor 5 which can be connected to the power grid for power supply and for driving at least one drive means 6 of the drive system 1 and an internal combustion engine 7 which is independent of the power grid and for driving the at least one drive means 6.

[0048] It is not shown in detail whether the electric motor 5 can be connected to the power grid, but this is intended.

[0049] In the Fig. In the embodiment shown in Figure 1, the drive means 6 is designed as a drive shaft. Other embodiments of the drive means 6 are fundamentally possible.

[0050] In the present case, a diesel engine is provided as the internal combustion engine 7, or the internal combustion engine 7 is powered by diesel fuel.

[0051] The Fig. The drive system 1 shown in Fig. 1 is designed such that the drive energy required to drive the drive system 1 can be applied either by the electric motor 5 or by the combustion engine 7, wherein the drive means 6 is coupled to at least one hydraulic point 8 of the drive system 1.

[0052] In Fig. 1 shows that a drive means 6 is connected to a plurality of hydraulic pumps 8. The hydraulic pumps 8 can be supplied with energy, which is necessary for operating the hydraulic pumps 8, via the drive means 6.

[0053] In Fig. 1 further shows that a control device 9 is provided for selectively switching between the electric motor 5 and the internal combustion engine 7, so that the drive energy required to drive the at least one drive means 6 is generated either by the electric motor 5 or by the internal combustion engine 7. The control device 9 can, in particular, take into account whether the electric motor 5 is connected to the power grid or whether a changeover / switchover, particularly one specified by a remote control unit, is to take place. Ultimately, the control device 9 enables switching between driving the drive means 6 via the internal combustion engine 7 or the electric motor 5.

[0054] It is not shown in detail that the hydraulic pump 8 is provided for directly driving a screening means 10 of the separating device 2 or a comminuting means 11 of the comminuting device 3 of the device 4. In Fig. 7 shows that a screening drum is provided as screening means 10, wherein the Fig. 9 as screening agent 10 a flat deck screen and the Fig. 10 shows a screen deck made of spiral waves or so-called “screw flights” as screening medium. Fig. 8 shows a comminution means 11 which is designed as a comminution roller with a roller base body and comminution tools 22 arranged on the outside of the roller base body.

[0055] The Fig. 4 also shows a drive system 1. In addition, the Fig. 4 further shows that the drive system 1 is designed to drive at least one linear or rotary hydraulic motor 12 of a screening means 10 of the separating device 2 or of a comminution means 11 of the comminution device 3. Fig. 4 two hydraulic motors 12, which are designed either as linear or rotary hydraulic motors. The arrangement of the hydraulic motors 12 on the hydraulic pumps 8 is shown only schematically. The hydraulic motors 12 can be supplied with hydraulic fluid and thus with the drive energy required for the drive via the hydraulic pumps 8.

[0056] The Fig. 1 shows a plurality of hydraulic pumps 8, wherein one hydraulic pump 8 is designed as an adjustable main hydraulic pump 13 and at least one further hydraulic pump 8 is designed as a constant secondary hydraulic pump 14. The Fig. 4 shows that in addition to the adjustable main hydraulic pump 13, an adjustable secondary hydraulic pump 14 is also provided.

[0057] The main hydraulic pump 13 serves in particular to drive the screening means 10 or the comminution means 11 and / or the hydraulic motor 12 for the screening means 10 and / or the comminution means 11.

[0058] The hydraulic pump 8, designed as a secondary hydraulic pump 14, can be designed to drive further means of the separating device 2 or the comminution device 3. Such further means are described, for example, in the Fig. 7 to 10. For example, the auxiliary hydraulic pump 14 can be provided for driving or displacing a conveyor belt 20, as shown in the Fig. 7, Fig. 9 and Fig. 10. The conveyor belts 20 are to be driven only when needed, and in particular not permanently / continuously. Fig. 8, a secondary hydraulic pump 14 can also serve as a required drive for a counter comb 21 interacting with the comminution tools 22. It is understood that the aforementioned means can also be driven, in particular, by hydraulic motors 12, which can be supplied with energy and / or hydraulic fluid as needed via the constant or adjustable secondary hydraulic pump 14.

[0059] In the Fig. 1 and Fig. 4 shows that the hydraulic pumps 8 are arranged one behind the other on or at the drive means 6, preferably sealing each other.

In Fig. 4 shows that only the internal combustion engine 7 is coupled to the drive means 6 by a connecting means 15, wherein the electric motor 5 is arranged, in particular, directly on the electric motor 6 without the interposition of a connecting means 15. Not shown in detail is the fact that only the internal combustion engine 7 can be coupled to the drive means 6 without a connecting means 15, wherein the electric motor 5 is connected to the drive means 6 via a connecting means 15.

[0061] In principle, it can also be provided that the motors 5, 7 are not arranged directly on the drive means 6, but no connecting means 5 is provided for each of them. Then, it can be provided that a transmission means 16 arranged on the motor 5, 7 interacts with a further transmission means 17 on the drive means 6.

[0062] In the Fig. 1, the connecting means 15 is designed as a belt, so that the at least one drive means 6 forms a belt transmission with both the electric motor 5 and the combustion engine 7. Fig. 4 shows that a belt transmission is formed only between the combustion engine 7 and the drive means 6.

[0063] It is not shown in more detail that the connecting means 15 can also be designed as a chain and / or traction means.

[0064] The Fig. 5 shows that the connecting means 15 is designed as a gear, which gear can then be coupled to a further transmission means 17. This further transmission means 17 can be assigned to the drive means 6 or arranged thereon. Not shown in detail is that, when the connecting means 15 is designed as a gear, the at least one drive means 6 forms a gear transmission with the electric motor 5 and / or the internal combustion engine 7.

[0065] In Fig. 6 schematically shows that the connecting means 15 is designed as a friction wheel, which also cooperates with a further transmission means 17 for the drive means 6. However, it is not shown in more detail that a friction gear is formed in this way between the at least one drive means 6 and the electric motor 5 and / or the combustion engine 7.

[0066] In Fig. 1 shows that a transmission means 16 is arranged on the electric motor 5 and the combustion engine 7 for coupling with the connecting means 15.

A pulley, a gear, and / or a friction wheel can be provided as the transmission means 16, in particular depending on the design of the connecting means 15 or the further transmission means 17, depending on whether the transmission means 16 interacts directly with the connecting means 15 or the further transmission means 17.

[0067] In addition, the Fig. 1, that on the drive means 6, as previously explained, a further transmission means 17 is arranged for coupling to the connecting means 15. It is not shown in more detail that the further transmission means 17 can also be directly coupled or connected to the transmission means 16 in further embodiments not shown in more detail. The further transmission means 17 can also be designed as a pulley, gear, and / or friction wheel—particularly depending on the design of the connecting means 15 and / or the transmission means 16.

[0068] It is not shown in more detail that a transmission means 16 is provided on the electric motor 5 and / or the internal combustion engine 7 for direct coupling with a further transmission means 17 arranged on the drive means 6, preferably for torque transmission, in particular wherein the transmission means 16 and / or the further transmission means 17 can be designed as a gear wheel and / or as a friction wheel.

In particular, at least one coupling device 18 can be interposed between at least one further transmission means 17 and the drive means 6, which also Fig. 1. Alternatively or additionally, it may be provided that at least one coupling device 18 is interposed between a transmission means 16 and the respective connecting means 15 and / or the respective transmission means 17.

[0070] In the embodiments according to the Fig. 2 and Fig. 3 are schematically the arrangements of the Fig. 1 shown motors 5, 7 on the drive means 6. Here, the coupling device 18 is particularly assigned to the drive means 6 or arranged in the drive means 6, so that the coupling device 18 acts between the further transmission means 17 and the drive means 6.

[0071] A coupling device 18 can also be provided if the motor 5, 7 acts directly on the drive shaft 6, as shown in Fig. 4. This is particularly useful when switching from one motor to the other and rotation of the inactive motor is to be avoided, in particular so that the torque transmission between the drive means 6 and the respective inactive motor is interrupted.

[0072] It is not shown that the coupling device 18 has at least one tensioning means assigned to the electric motor 5 and / or the internal combustion engine 7 for relaxing and tensioning a connecting means 15 designed as a drag belt, in particular wherein in the tensioned state of the drag belt the drive energy is transmitted to the drive means 6 and in the relaxed state the electric motor 5 or the internal combustion engine 7 is decoupled from the drive means 6.

[0073] It is also not shown in more detail that in further embodiments the clutch device 18 has at least one clutch, in particular a friction clutch and / or a dog clutch, associated with the electric motor 5 and / or the internal combustion engine 7.

[0074] The Fig. 2 and Fig. 3 illustrated clutch device 18 has a freewheel 19. The freewheel 19 is in the Fig. 2 and Fig. 3 is shown only schematically. However, different freewheels 19 known from the prior art are fundamentally suitable for use with the clutch device 18. In particular, a freewheel 19 can be interposed between at least one further transmission means 16 and the drive means 6. Alternatively or additionally, it can be provided that at least one freewheel 19 is interposed between at least one transmission means 16 and the respective connecting means 15 (assigned to the further transmission means 16 or directly interacting with it) and / or the respective further transmission means 17 (assigned to the further transmission means 16 or directly interacting with it).

[0075] A further alternative, which can also be implemented together with the aforementioned embodiments, provides that a freewheel 19 can also be arranged on the drive means 6 for the clutch to the electric motor 5 and a further freewheel 19 can be arranged on the drive means 6 for the clutch to the combustion engine 7, as is the case with Fig. 2 and Fig. Show 3.
