Abstract

A device for a vehicle drive train for generating and transmitting drive torque to components of the drive train. The device comprises a shaft which is connected to the components of the drive train, at least first and second bearings which support the shaft and an electric motor for generating the transmitted drive torque. The electric motor comprises a stator and a rotor which is fixed to the shaft. The rotor is supported by one or more bearing surfaces. The device also comprises elements disposed on the shaft via which drive torque can be transmitted to the components of the drive train while introducing transverse force into the shaft. The rotor of the drive motor is positioned on the shaft such that the bearing surface is located in the region of maximum deflection caused by the transverse force in the shaft.
