Abstract
A pressure plate assembly for a friction clutch includes a housing for mounting to a centrifugal mass; a pressure plate, which is mounted 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, 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 a gripping element provided on the pressure plate, which, when wear occurs, comes to rest or can be brought to rest against a blocking element, which is fixed or can be fixed in place relative to the housing arrangement. During or after the connection of the housing arrangement to the centrifugal mass arrangement, the blocking element arrives in or can be brought into a state in which it can enter into a blocking interaction with the associated gripping element.
