Abstract
A drive system for a motor vehicle includes an electric machine arranged for driving a driveshaft of a drive unit and obtaining electrical energy during rotation of the driveshaft. The electric machine has a stator arrangement and a rotor arrangement which is connectable to the driveshaft for common rotation. The rotor arrangement is connectable to the driveshaft via an elastic connecting arrangement.
Claims18
A drive system for a motor vehicle, comprising an electric machine selectively operable in one of a starter mode for driving a drive shaft and a generator mode for obtaining electrical energy from rotation of the drive shaft, said electric machine comprising a stator arrangement, a rotor arrangement, and an elastic connecting arrangement connected to said rotor arrangement for rotation with said rotor arrangement about an axis of rotation, wherein said rotor arrangement is connectable to the drive shaft via said elastic connecting arrangement such that said rotor arrangement remains centered relative to said stator arrangement during wobbling of the drive shaft relative to said axis of rotation and such that said rotor arrangement is maintained in a fixed relationship with respect to rotation relative to said drive shaft.
