Abstract

A pressure plate assembly for a friction clutch includes a housing, a pressure plate held in the housing arrangement with freedom to move axially, and a stored-energy element transmitting force along a path between the housing and the pressure plate. A wear-compensating device acting in the path of force transmission has at least one adjusting element able to move in an adjusting direction to compensate for wear. At least one spring element pretensions the minimum of one adjusting element for movement in the adjusting direction, where at least certain areas of the minimum of one spring element extend in the circumferential direction relative to the rotational axis (A). A support arrangement supports the area of the spring element extending essentially in the circumferential direction radially from the outside and/or radially from the inside relative to the rotational axis (A).
