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.

Pressure plate assembly

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 section that the minimum of one gripping element interacts with the blocking element.

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).
