Abstract

A friction clutch with a housing, a clutch disk having friction facings, and a diaphragm spring which presses a pressure plate against the clutch disk, contacts a knife edge formed at the pressure plate when the clutch is engaged, and lifts off from this knife edge to open the clutch. The housing and the diaphragm spring are connected so as to be fixed with respect to rotation relative to one another. The housing has a plurality of recesses which are arranged so as to be distributed along the circumference at the height of the knife edge. The diaphragm spring is provided on the radial outer side with a corresponding quantity of fingers, each of which engages in a recess when the clutch is open.
