Abstract
A friction clutch wherein stray axial and/or radial and/or angular movements of the pressure plate relative to the counterpressure plate, clutch disc, clutch housing and/or clutch spring are opposed by a damper having prestressed resilient portions forming part of a sensor, which latter abuts the clutch spring, and bearing against a finished, partly finished or rough-finished internal surface of the pressure plate. The sensor forms part of a unit which automatically compensates for wear upon the pressure plate, counterpressure plate, clutch spring and/or friction linings of the clutch disc in response to repeated engagement and disengagement of the friction clutch.
