Problems solved by technology
[0004] Another problem in electric vehicles is that, unlike conventional vehicles such as internal combustion engine drives or hybrid vehicles, electrically driven vehicles for pure vehicle operation do not require a starting clutch for limiting the impact torque of the wheels, which Simultaneously acts as a slipping clutch due to slipping in overload situations
[0006] Therefore, the background art always has the disadvantage that shocks and overload moments are not adequately limited and the electrical connection between the output shaft and the input shaft is not allowed in the electric drive system of the motor vehicle, or that in a compact design the existing structures There is not enough space for the insulated connections described in the background
Additionally, replacement of worn insulation elements inside the motor or transmission is cumbersome and expensive

Embodiment Construction
[0046] figure 1 A first embodiment of a torque limiter 1 according to the invention for a motor vehicle powertrain system is shown. The torque limiter 1 has a torque input member 2 for transmitting the torque of the electric motor 3 in the direction of the transmission 4 . The torque limiter 1 has a slip clutch 5 for limiting the peak torque, which is designed as a multi-plate clutch with friction plates 6 which can be brought into frictional contact. Here, the input friction lining carrier 7 is connected to the torque input member 2 in a rotationally fixed manner. The torque limiter 1 has a torque output member 8 for transmitting torque to the transmission 4 . The torque output member 8 is connected in a rotationally fixed manner to the output lining carrier 9 of the slip clutch 5 . The torque flow is as follows: Torque is generated by the electric motor 3 and transmitted to the slip clutch 5 through the torque input member 2 . Torque is transmitted from the slip clutch 5...
