Abstract
A friction clutch wherein the wear upon the friction linings of the clutch disc is automatically compensated for in response to each disengagement and subsequent engagement of the clutch whenever an adjustment for wear is necessary. The compensating unit is mounted between the axially movable pressure plate and the diaphragm spring of the friction clutch, and the extent of axial adjustability of the pressure plate to compensate for wear upon the friction linings is determined by an arresting unit having one or more sensors carried by the pressure plate and cooperating with the counterpressure plate and/or with the cover of the friction clutch. The compensating unit comprises a ring-shaped locating element which is biased by the diaphragm spring toward the pressure plate, and two sets of wedges having abutting ramps which can shift the pressure plate and the locating element axially relative to one another in response to angular movement of one set of wedges relative to the other set.
