Abstract

A motor vehicle friction clutch with automatic wear compensation has a wear compensation element, which wear compensation element can rotate around a clutch axis. The friction clutch also includes an adjustment device, which adjustment device includes a worm rotatably mounted on a carrier. The wear compensation element is a worm gear that meshes with the worm to advance the wear compensation element along the clutch axis to compensate for wear. Axial play in the direction of the clutch axis is provided between the worm gear and the worm to detect wear of the friction linings.
