Abstract:
A thrust plate assembly for a motor vehicle friction clutch having automatic wear compensation, comprising:a housing connectable to a flywheel for rotation therewith about an axis of rotation; a pressure plate fixed with respect to rotation and axially displaceable relative to said housing; a force accumulator supported between said housing and said pressure plate; a wear adjustment device arranged in a support path of said force accumulator between said force accumulator and one component of one of said housing and said pressure plate, said wear adjustment device comprising at least one adjustment element displaceable for effecting wear compensation, said at least one adjustment element being preloaded in a wear adjustment direction; at least one play indicator arrangement including a blocking/detection element arranged on said one component and comprising a blocking section arranged for acting on said wear adjustment device to prevent the movement of said at least one adjustment element in the wear adjustment direction, said blocking/detection element further comprising a detection section; and a stop component having a stop face region and being arranged on another component of said thrust plate assembly other than said one component such that said stop component is displaceable relative to said one component in response to wear, wherein said detection section is arranged for interaction with said stop face region such that said blocking/detection element is movable into a position for releasing said at least one adjustment element and allowing movement of said at least one adjustment element in the wear adjustment direction via the interaction with said stop face region, said stop face region comprising at least two face sections having different axial positions with respect to said axis of rotation, wherein a position of said stop component relative to said another component is adjustable for selecting one of said at least two face sections for the interaction with said detection section.
