Abstract
A motor vehicle friction clutch with automatic wear adjustment comprises a flywheel which rotates about a rotational axis, a clutch housing positioned with contact on the flywheel to turn with the flywheel, a pressure plate that is non-rotationally connected to the clutch housing and can be axially displaced with respect to the flywheel and a clutch disc that is rotationally arranged between the pressure plate and the flywheel with interposition of friction linings around the rotational axis in relation to the flywheel. A membrane spring element is installed to pre-stress the pressure plate in the direction of the flywheel. At least one clearance sensor is provided at the pressure plate and the clearance sensor has a control lever segment which acts with the wear adjustment device and an axial stop segment which acts with the flywheel. Through a friction ratcheting of the control lever segment, the clearance sensor is fixated on the pressure plate by pre-stressing in the axial direction.
