Abstract

A thrust plate assembly for a motor vehicle friction clutch with automatic wear compensation includes a housing fastened to a flywheel for common rotation about an axis of rotation. An axially displaceable pressure plate is connected with the housing so as to be substantially fixed with respect to rotation relative to it and has a friction face on a side facing the flywheel. An axially acting spring device presses the pressure plate toward the flywheel via an axially acting adjusting mechanism and accordingly can clamp a driven part arranged between the pressure plate and the flywheel. At least one play sensor is guided in the thrust plate assembly so as to be substantially axially displaceable against friction. A wear detection portion of the play sensor is axially displaceable in the thrust plate assembly in response to wear and an actuation portion of the play sensor cooperates with the adjusting mechanism for allowing an axial lengthening of the adjusting mechanism in response to wear. The thrust assembly also includes at least one device for securing the adjusting mechanism against rotation.
