Friction clutch device for powertrain of combustion engine-driven motor car, has cup spring including spring tongues that are actuated by actuator and other spring tongues for supporting on housing to compensate increase of release force

摘要

The device (100) has a pressing plate moved between an engaging position and a disengaging position for actuation of the device relative to housing (102) in an extending direction of a rotational axis. A swingable cup spring (104) loads the pressing plate and couples a disk with friction linings and an actuator. The cup spring includes first set of L-shaped spring tongues (116) that are actuated by the actuator and second set of L-shaped spring tongues (106) for supporting on the housing to partially compensate increase of release force during wearing of the friction linings.
