Embodiment Construction

[0017] The drive of the differential gear 18 enables the transmission of the drive torque generated by the electric motor 12 to half shafts 20 a , 20 b connected to the wheels of the motor vehicle (not shown). The electric motor 12 has a rotor connected in a rotationally fixed manner to a hollow shaft 22 . The hollow shaft 22 is connected to a slip clutch 24 which is arranged functionally between the electric motor 12 and the gear unit 14 . The slip clutch 24 is designed as a multi-disc clutch and comprises outer disks 26 a and inner disks 26 b arranged alternately forming a disk pack. The disc springs 28 press the diaphragms 26a, 26b against each other with a predefined force in order to provide a well-defined coupling between the hollow shaft 22 coaxially surrounding the half shaft 20b and the input shaft 30 of the reduction gear 14 .

[0018] The speed reducer 14 is designed as a two-stage planetary gear transmission. The input shaft 30 is connected in a rotationally fixe...

Abstract

The invention relates to a torque transmission device for a motor vehicle having a locking mechanism for locking at least one wheel of the motor vehicle connected to an output shaft of the torque transmission device. The torque transmission device includes a differential gear connected to the output shaft and a drive unit, which are connected to each other in a drive-capable manner via a clutch unit. The locking mechanism can mesh with a rotatable component of the torque transmission device which is functionally arranged between the wheel and the clutch unit.

Description

technical field [0001] The invention relates to a torque transmission device for a motor vehicle having a locking mechanism for locking at least one wheel of the motor vehicle connected to an output shaft of the torque transmission device. Background technique [0002] Such torque transmission devices with locking mechanisms are used in many types of motor vehicles, especially in electric or hybrid vehicles. The locking mechanism can be used, for example, as a parking lock to prevent the motor vehicle from rolling when parked. Reliable locking is of particular importance here, so that the safety of the motor vehicle is always ensured even with high loads acting on the locking mechanism (for example, when the motor vehicle is parked on a slope). Such a locking mechanism must also be designed such that it can be inserted even when the motor vehicle is still rolling slowly. This requires a very robust design of the locking mechanism, which entails corresponding manufacturing ...
