Patent ID: 8413750

Claim:
A device for a vehicle drive train for generating and transmitting drive torque to components ( 3 , 13 ) of the drive train, the device comprising: one of a one-piece and a multiple-part shaft ( 2 ) being operatively connected, on an output side thereof, to the components ( 3 , 13 ) of the drive train; at least first and second bearings ( 4 , 5 ) rotatably supporting the shaft ( 2 ); and an electric drive motor ( 1 ) for generating at least a portion of the transmitted drive torque, the drive motor ( 1 ) comprising at least a stationary stator ( 9 ) and a rotor ( 7 ) which is non-rotatably connected to the shaft ( 2 ), and the rotor ( 7 ) being supported on the shaft ( 2 ) via at least one bearing surface ( 8 ); wherein means ( 12 ) is disposed on the shaft ( 2 ) by which drive torque is transmittable to the components ( 3 , 13 ) of the drive train while introducing at least one transverse force into the shaft ( 2 ), the rotor ( 7 ) of the drive motor ( 1 ) is positioned on the shaft ( 2 ) such that the bearing surface ( 8 ) is located in a region of maximum ( 15 ) deflection caused by the transverse force in the shaft ( 2 ) and centered with respect to the region of the maximum ( 15 ) deflection so as minimize tilt of the rotor ( 7 ) relative to the stator ( 9 ) upon deflection of the shaft ( 2 ).
