A friction clutch wherein the wear upon the friction linings of the clutch disc and, if necessary, upon the friction surfaces of the pressure plate and the counterpressure plate is compensated for by an adjusting unit which can shift the pressure plate toward the counterpressure plate to the extent which is necessary to compensate for wear. The friction clutch is further provided with a blocking or braking mechanism which can respond to the action of centrifugal force to prevent shifting of the pressure plate, e.g., in response to vibratory movements of the prime mover which transmits torque to the rotary components of the friction clutch, under circumstances when such shifting of the pressure plate is not necessary due to absence of wear, or additional wear, upon the pressure plate, the counterpressure plate and/or the friction linings. |
