Abstract
A device for actuating a friction clutch with automatic adjustment. An actuating movement for engaging and disengaging the clutch is transmitted to a pressing component. The adjusting device includes a sensing component that is biased in the direction of an adjusting movement and compensates for sensing play that occurs as a result of wear when the clutch is engaged, and that compensates for play that occurs when the clutch is disengaged after compensation of the sensing play in the movement transmission between the actuating component and the transmission component. When the clutch is engaged and wear is present, the sensing component moves out of contact against a spring component which, when the clutch is engaged and wear is present, comes into contact against a stop before the fully engaged state of the clutch is reached.
