Clutch unit for a motor vehicle

A clutch unit for a motor vehicle, said clutch unit comprising:

• a crankshaft starter-generator comprising a stator having a stator coil mounted on a stationary component, and a flywheel which can rotate about an axis of rotation, said flywheel having at least one permanent magnet with a pole field which can be moved past the stator coil, thereby forming a rotor;
• a first clutch by which a crankshaft of an internal combustion engine can be connected to said flywheel;
• a second clutch by which a transmission shaft can be connected to said flywheel, wherein at least one of said first and second clutches comprises a clutch disk which is axially flexible and can rotate about said axis of rotation, said clutch disk having a friction lining and an area which pretensions the friction lining into a position which is at an angle to a radially oriented position, said flywheel having a friction surface corresponding to each said clutch disk;
• a pressure plate for each said clutch disk, each said pressure plate having a friction surface which can exert an axial force against the respective clutch disk to press the disk against the respective friction surface of said flywheel;
• and
• separately operated actuating means for actuating each of said first and second clutches, whereby said first and second clutches can be engaged either independently or in common.
