Abstract

A pressure plate assembly for a friction clutch includes a housing; a pressure plate held in the housing with freedom to move in the same direction as that in which a rotational axis (A) extends; 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 and/or between the stored-energy element and the housing arrangement, where the wear-compensating device has at least one adjusting element able to move in an adjusting direction to compensate for wear. A clearance-producing arrangement includes at least one gripping element, where the minimum of one gripping element has a body section, one end of which is attached to the assembly consisting of the pressure plate and the housing, between which assembly and the stored-energy element the wear-compensating device acts. The other end of the body section is designed with a blocking section projecting laterally from the body section to act on the wear-compensating device and to interact with a blocking element, which is able to shift position relative to at least part of the gripping element when wear occurs. It is in the area of its body secti…
