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.
