Abstract: A pressure plate assembly for a friction clutch includes a housing, a pressing plate arranged to rotate with the housing, and a force accumulator arranged to exert an axial force on the pressing plate. A wear take-up element between the accumulator and the pressing plate moves to adjust for wear, and an adjusting member is brought into a take-up starting position when wear occurs and is acted on by centrifugal force in order to carry out an adjusting movement wherein the adjusting member moves out of the take-up starting position. The adjusting member cooperates with the wear take-up element by way of a transmission member which moves with respect to the wear take-up element when the adjusting member is brought into the take-up starting position. During the adjusting movement, the transmission member is acted upon by the adjusting member and moves jointly with the wear take-up element.

Abstract: A pressure plate assembly for a friction clutch has at least one wear take-up element operable to move between a pressure plate and a force-exerting arrangement to compensate for the wear of the pressure plate.

Abstract: A wear take-up device in the path of force transmission between the pressure plate and the force-exerting arrangement includes at least one take-up element, which can be shifted to compensate for wear; a blocking element with a detection section which can come to rest against a stop fixed to the housing upon the occurrence of wear and which can move with respect to the pressure plate; and a wedge-like arresting element, which is pretensioned by a pretensioning arrangement toward a state in which the detection section is arrested and thus prevented from returning to its previous position. A retaining device opposes the pretensioning action of the pretensioning arrangement at least under the conditions in which the detection section has essentially not been moved out of an arrested position with respect to the pressure plate.
