Abstract
A drive system for a motor vehicle includes a drive shaft with a flywheel mass arrangement provided thereon, an electric machine for driving the drive shaft and/or obtaining electric energy from the rotating drive shaft. The electric machine has a stator arrangement and a rotor arrangement which can be rotated by the drive shaft. The rotor arrangement is connected via the flywheel mass arrangement to the drive shaft. Furthermore, the rotor arrangement is connected to the flywheel mass arrangement via a connecting region having a higher resistance to thermal conduction than at least one of the regions that adjoins the connecting region.
Claims24
A drive system for a motor vehicle, comprising:
- a drive shaft arranged for rotating about an axis of rotation;
- a flywheel mass arrangement arranged on said drive shaft for rotating with said drive shaft;
- an electric machine having a stator arrangement and a rotor arrangement rotatable relative to said stator arrangement for rotation about said axis of rotation, said rotor arrangement being connected to said drive shaft via said flywheel mass arrangement and being operative for one of exerting a torque for rotating said drive shaft and obtaining electric energy from rotation of said drive shaft;
- and
- a connecting region arranged between a first adjoining region of said flywheel mass arrangement and a second adjoining area of said rotor arrangement, said connecting region connecting said rotor arrangement to said flywheel and having a higher resistance to thermal conduction than at least one of said first and second adjoining regions.
