Abstract: A friction clutch for coupling a drive shaft of a motor vehicle engine to a transmission input shaft of a motor vehicle transmission. An input disk carrier is couplable to the drive shaft and an output disk carrier is couplable to the transmission input shaft. A return spring positions the output part in a defined initial position relative to the input part. The return spring allows a higher pressing force between the input part and the output part in the engaged state when the friction lining is in a worn condition than when the friction lining is in the non-worn condition. Through the use of the return spring to also transfer torque, a pressing force that reduces as the friction linings become worn can be compensated for by changing the direction of force of the torque introduced through the return spring for reliable engagement of the friction clutch.
