Abstract: A multi-disc clutch comprises a pressure plate, an intermediate plate and two clutch discs on both sides of the intermediate plate. A main spring urges the pressure plate towards a fly-wheel so that the clutch discs are in frictional engagement with the pressure plate, the intermediate plate and the fly-wheel. When the clutch disc is disengaged the pressure plate and the intermediate plate are lifted away from the fly-wheel. The lifting movement of the intermediate plate is effected by a release spring and is controlled by supporting the intermediate plate on a counter support which counter support is axially movable in response to the action of a clutch disengaging member. The counter support is established by a member which has an additional essential function within the clutch. For example, the counter support is established by the main spring or by a leaf spring connecting the pressure plate for common rotation with the clutch cover.

Abstract: A pressure plate unit for a pulled-type friction clutch comprises a presser plate which is connected with the diaphragm spring through retaining elements to ensure the disengagement action. The retaining elements extend substantially radially within a circle along which the pressure plate rests on the diaphragm spring. The retaining elements are secured non-rotatably in relation to the presser plate and the diaphragm spring. Different retaining elements are proposed. Distance bolts screwed into the presser plate with leaf spring elements can be used. Likewise U-shaped springs can be used which are hooked into radial openings of a bead of the presser plate. Furthermore the retaining elements can be secured on the diaphragm spring or an additional ring and locked with the pressure plate by means of a circumferential groove of the bead.
