Abstract
A friction clutch for use in motor vehicles wherein the pressure plate is automatically shifted toward the counterpressure plate for the friction linings of the clutch disc in dependency on the extent of wear upon the counterpressure plate, pressure plate and particularly the friction linings. The pressure plate is non-rotatably but axially movably coupled to the housing of the friction clutch and is biased toward the friction linings by resilient means including a diaphragm spring or a set of coil springs. The adjusting unit which changes the position of the pressure plate as a function of the extent of wear mainly upon the friction linings can employ cooperating wedges including a set of wedges on the housing and a set of wedges on the resilient means.
