ABSTRACT:
A pressure plate assembly for a friction clutch including a housing having an axis of rotation; a pressure plate mounted in the housing with freedom to move axially relative to the housing; a stored-energy element mounted in the housing and transmitting force along a path from the housing to the pressure plate; a wear-compensating device in the path of force transmission, which device has at least one adjusting element free to move in an adjusting direction to compensate for wear; and a clearance-producing arrangement having at least one gripping element, which is attached to the assembly upon which the stored-energy element acts via the wear-compensating device. The minimum of one gripping element has a blocking section, by means of which it can make blocking contact with a blocking element when wear occurs. The clearance-producing arrangement also includes an arresting element which can be shifted in an arresting direction when the gripping element comes into contact with the blocking element, thereby arresting the gripping element in the shifted position correlating with the amount of wear which has occurred. A transport-securing device prevents moving the adjusting element in the adjusting direction and/or moving the arresting element in the arresting direction prior to attaching the housing to the centrifugal mass.
