ABSTRACT:
A pressure plate arrangement (1) for a friction clutch of a motor vehicle is proposed, wherein an adjustment device (19), which automatically compensates for the wear of the friction linings (21), is disposed in the support path between a diaphragm spring (13) and a pressure plate (11), stressed against a flywheel (1) by the diaphragm spring (13) via friction linings (21) of a clutch disk (23). The adjustment device (19) has a pressure path compensating member (31), for example in the form of a radially resilient cone-shaped ring, which automatically compensates for possible play between the diaphragm spring (13) and the pressure plate (11). Distributed in the circumferential direction, a plurality of play transfer devices (37) is axially movably guided and arrested (for example by self-locking). The play transfer devices (37) rest against the flywheel (1) of the clutch housing (9) fixedly connected therewith and have levers (43) which limit the maximal wear compensation path of the compensating member (31). In this manner a wear compensation, which is independent of possible wear compensation mechanism of a hydraulic clutch disengagement system, takes place within the clutch. In addition, the diaphragm spring (13) of the proposed pressure plate arrangement retains its original position in relation to the flywheel (1) or the clutch housing (9), regardless of a possible wear compensation.
