Abstract
A friction clutch, particularly suitable for automotive vehicles, comprises a clutch release bearing disposed in axial face-to-face relationship with a diaphragm spring. The spring is mounted inside a clutch cover assembly and has a plurality of centripetal radial fingers around a central hole. The release bearing is adapted to act in traction on these fingers by means of a transverse annular flange disposed inside the cover assembly. The fingers of the diaphragm spring are formed so as to provide a penetration passage through the diaphragm spring for the transverse annular flange, along a penetration direction which is at an acute angle to the median plane of the fingers of the diaphragm spring. A pull type release bearing is obtained by adding a bush forming the transverse annular flange to the drive member of a push type release bearing.
