Abstract
A friction clutch, especially for motor vehicles, includes a housing connectable with respect to rotation to a flywheel of an internal combustion engine. A pressure plate is arranged in the housing and is urged by a spring toward the flywheel. A clutch disk with friction facings is arranged between the pressure plate and the flywheel such that the spring presses the friction facings ot the clutch disk against the flywheel. A compensation device with at least one element which is changeable along its axial dimension compensates for the change in position of the pressure plate caused by wear of the friction facings, wherein the contact pressure force of the spring acts on the pressure plate via the compensation device. A play transmitter includes two levers, one arranged on each side of the compensation device. One of the levers penetrates the other lever. The penetrated lever includes a stop element which limits the axial movement of the penetrated lever.
