Abstract
A structurally and/or functionally improved friction clutch device is disclosed. In particular, a servo spring for a clutch is to be provided which is suitable for series production. In particular, the servo spring is to be realized in the clutch while integrating already existing components. In particular, the servo spring is to keep a maximum disengaging force low. In particular, the servo spring is to operate only under worn conditions; in the new state and during separation it should be possible for it to be force-free. In particular, the total tolerance in the friction clutch device is to remain small, so that the susceptibility of the servo spring force to tolerance deviations is limited.
