Problems to be Solved by the Invention

[0007] Therefore, an object of the present invention is to provide a new device for driving a vehicle and a new vehicle. [Means for solving the problem]

[0008] This objective is achieved by the subject matter of the independent claim.

[0009] The apparatus comprises a housing, a drive train device, a locking device, and a support member, wherein the drive train device is at least partially located within the housing, the locking device comprises a housing element, the housing comprises a recess, the locking device is at least partially located within the recess and connected to the housing, the locking device is configured as a mechanical locking device for controlled locking of the drive train device, the support member is connected to the housing and is at least partially located outside the locking device such that removal of the locking device is possible only after removal of the support member, and the support member is configured to enable fastening of the apparatus. The support member can, as herein states, cover the locking device, making undesirable removal of the locking device more difficult or impossible.

[0010] According to a preferred embodiment, the drive train device is - Combustion engine, - Electric motor, - It comprises at least one drivetrain element from a first group of drivetrain elements consisting of a hybrid engine.

[0011] Because such engines are relatively heavy, it makes it difficult to disassemble the support members that bear the load of the device. Preferably, this drive train element is located at least partially within a housing.

[0012] According to a preferred embodiment, the drive train device is - Automatic transmission, - Manual transmission, - It comprises at least one drive train element consisting of a second group of drive train elements, which includes a clutch.

[0013] These drive train elements enable good locking of the drive train device. Preferably, these drive train elements are located at least partially within the housing.

[0014] According to a preferred embodiment, the minimum distance between the support member and the locking device is less than 5.0 cm, preferably less than 3.0 cm, more preferably less than 2.0 cm, even more preferably less than 1.0 cm, and more preferably less than 0.5 cm.

[0015] This ensures that the locking device is not disassembled without prior disassembly of the support members.

[0016] According to a preferred embodiment, at least a first fastening element is provided for fastening the locking device to the housing. The mounting makes disassembly even more difficult.

[0017] According to a preferred embodiment, the support member includes a projection extending toward the locking device in order to reduce the distance between the support member and the housing in the area of ​​the projection, compared to a configuration without the projection.

[0018] According to a preferred embodiment, the locking device comprises a controllable actuator to enable mechanical locking of the drive train device. Mechanical locks are more difficult to handle than electronic locks.

[0020] According to a preferred embodiment, the drive train device includes a transmission, and the locking device is configured to mechanically prevent a change in the position of the transmission when the locking device is activated. Thereby, the driver can be prevented from speeding away on normal road traffic.

[0021] According to a preferred embodiment, the drive train device is provided within a housing.

[0022] The vehicle includes such a device. Due to the compact design, it becomes more difficult to disassemble the vehicle outside the workplace.

[0023] Further details and advantageous further developments of the present invention will be described below, illustrated in the drawings, and design examples that should not be construed as limiting the present invention in any way, and will result from the dependent claims. Of course, the features described above and the features to be discussed hereinafter can be used not only in the specified combinations, but also in other combinations or by themselves, without departing from the scope of the present invention.

Modes for Carrying Out the Invention

[0025] Parts that are the same or have the same effect are provided with the same reference number below and are usually described only once. All diagram descriptions are reused to avoid unnecessary repetition. Terms such as left, right, top, and bottom are not usually absolute and may vary depending, for example, the installation location or a particular viewing angle. However, this is a preferred orientation.

[0026] Figure 1 shows a schematic longitudinal cross-section of the device 20, which comprises a housing 30 and a drive train device 40. The drive train device 40 includes drive train elements 41, 42, and 43. For example, drive train element 41 is an electric motor or a combustion engine, drive train element 42 is a transmission, such as an automatic or manual transmission, and drive train element 43 is a shaft for transmitting torque.

[0027] For example, the housing 30 has a housing region 30A in which a drive train element 41 and a drive train element 42 are provided in part, a housing region 30B in which a drive train element 42 and a drive train element 43 are provided in part, and a housing region 30C in which the drive train element 43 extends.

[0028] Figure 2 shows a side view of the apparatus 20 of Figure 1. The housing 30 may be configured as a one-piece or multi-piece housing 30 and has a recess 32. Exemplary fastening elements 33A, 33B and 33C are also provided, which are formed, for example, as female threaded holes or threaded rods attached to the housing 30.

[0029] Further fastening elements 34A are provided on the housing 30 and are configured, for example, as female threaded holes attached to the housing 30, or as threaded rods.

[0030] Figure 3 shows the device 20 from the front or generally from the side where the shaft 43 is located or accessible.

[0031] Further fastening elements 34B and 34C are provided to the housing 30, for example, by female threaded holes or threaded rods.

[0032] Figure 4 shows a side view corresponding to Figure 2, and shows the device 20 having a locking device 50 inserted into the recess 32. The locking device 50 is fixed to the housing 30 via three fastening elements 53A, 53B, and 53C that cooperate with fastening elements 33A, 33B, and 33C. Cooperation may occur, for example, via a nut and a threaded rod, or via a screw and a female threaded hole.

[0033] The locking device 50 has a housing element 52 that protects the locking device 50 from the outside. The housing element 52 is, for example, a cover or a partial housing. A controllable actuator 54 is shown schematically.

[0034] The locking device 50 is provided to enable, for example, locking or partially locking the drive train elements 41, 42, and 43 by preventing the rotation of the shaft 43 by the locking device 50, at least partially. Preferably, the locking device 50 is a mechanical locking device having a mechanical element that restrains predetermined movement of the drive train elements 41, 42, and 43. This example includes a locking device 50 that completely restrains the rotation of the drive train element 41, 42, or 43 when starting, or, if the drive train element 42 is configured as a transmission, locks the transmission in a parked position or, conversely, fixes it in place.

[0035] Such a locking device 50 is intended to make unauthorized use of the vehicle virtually impossible by making it particularly difficult to steal a vehicle on which the device 20 is installed and virtually impossible to drive away. In order to bypass the locking device 50, a thief may attempt to remove the locking device 50 from the device 20, for example by unscrewing the locking device 50 and replacing the cover.

[0036] The locking device 50 preferably includes an actuator to enable mechanical engagement with the drive train elements 41, 42, and 43. The locking device 20 is preferably configured as a parking lock actuator.

[0037] Figure 5 shows the apparatus 20 of Figure 4, with an additional support member 60 for the apparatus 20.

[0038] The support member 60 is bolted to the fastening element 34A in Figure 2, for example, by fastening elements 65, particularly screws or nuts. For example, the support member 60 may be fixed to the device 20 via two, three, four, or five fastening elements 65.

[0039] In the right-hand region of the figure, a support member 62 is provided, which functions as a support member for the device 20.

[0040] In an exemplary embodiment, the support member 60 extends over a portion of the locking device 50.

[0041] The support member 60 has a recess 68 that allows the device 20 to be attached to a component fixed to the vehicle. Alternatively, a pin or threaded rod may also be provided on the support member 60 to enable connection to a component fixed to the vehicle.

[0042] Figure 6 schematically illustrates a vehicle 10 having a main body fixed console 11, 12 and a device 20. The device 20 is attached to the consoles 11, 12 via support members 60, 62 and further support members 61, 63. The connection of the device 20 to the consoles 11, 12 occurs in a so-called close coupling. It is preferable to provide elastic elements between the consoles 11, 12 and the main body of the vehicle 10 in order to dampen mechanical vibrations and provide (partial) isolation between the device 20 and the main body.

[0043] The support member 60, for example, has a projection 67 and fastening elements 66 are provided for mounting. The fastening elements 66 are, for example, a screw threaded into the fastening element 34B in Figure 3, or a nut for cooperation with a screw rod.

[0044] Since the support member 60 extends over all or part of the locking device 50, the locking device 50 is either inaccessible or only partially accessible, and disassembly of the locking device 50 is only possible by disassembling the support member 60 beforehand. On the other hand, the fastening elements 53A and 53B in Figure 4 are shielded by the support member 60, and in the case of screws, the screws cannot be removed. Also, because the support member 60 is in the way, the locking device 50 cannot be pulled out from the recess 32 in Figure 2.

[0045] In this respect, the support member 60, as a bearing element, has the advantage of having a bearing function for the device 20, and therefore cannot be simply unscrewed or disassembled without something else supporting the device 20.

[0046] Figure 7 shows a schematic cross-sectional view of the details of the device 20. The housing 30 has a fastening element 33B in the form of an internal thread. The locking device 50 has a fastening region through which the fastening element 53B extends in the form of a thread. The support member 60 has a projection 69 that extends toward the fastening element 53B and has a distance 70 from the fastening element 53B, which is relatively short or zero such that there is contact or at least a short distance.

[0047] The distance 70 is preferably less than 5.0 cm, more preferably less than 3.0 cm, even more preferably less than 2.0 cm, even more preferably less than 1.0 cm, and more preferably less than 0.5 cm. The distance 70 is at least 0.0 cm, preferably at least 0.1 cm, and more preferably at least 0.3 cm. A distance 70 greater than zero is advantageous to allow mechanical stress in this range in the case of expansion caused by temperature changes.

[0048] The projection 69 prevents the screw of the fastening element 53B from coming loose.

[0049] Naturally, a wide range of modifications and alterations are possible within the scope of this application. [Explanation of Symbols]
