  • Patent number: 6662923
    Abstract: A pressure plate assembly for a friction clutch includes a housing for mounting to a flywheel; a pressure plate, held in the housing with the freedom to move in the same direction as that of a rotational axis (A); a stored-energy element; and a wear-compensating device acting in the path of force transmission between the stored-energy element and the pressure plate, where the wear-compensating device has at least one adjusting element, which can move in an adjusting direction to compensate for wear. A clearance-producing arrangement includes a gripping element provided on the pressure plate, which element comes or can be brought to rest against a blocking element (fixed in position relative to the housing arrangement upon the occurrence of wear. When the housing arrangement is being attached to the flywheel arrangement, the blocking element arrives in state in which it is able to enter into a blocking interaction with the associated gripping element.
