Abstract:
A thrust plate assembly for a motor vehicle friction clutch with automatic wear compensation, comprising:a flywheel rotatably mounted for rotation about an axis of rotation;a housing fastened to said flywheel for rotation with said flywheel about said axis of rotation;a pressure plate connected to said housing so that said pressure plate is rotatable fixed to said housing and axially movable with respect to said housing, and said pressure plate having a friction face on a side of said pressure plate facing said flywheel;a diaphragm spring arranged between said housing and said pressure plate for urging said pressure plate toward said flywheel;an axially acting adjusting mechanism comprising a first adjusting ring facing said pressure plate and a second adjusting ring facing said diaphragm spring and arranged between said axially acting spring element and said pressure plate such that said axially acting spring element acts on said pressure plate via said axially acting adjusting mechanism, said axially acting adjusting mechanism having an adjustable axial length for compensating wear of the friction clutch;a play sensor having a wear detection portion axially displaceably arranged for axial displacement against friction relative to said pressure plate in response to the wear of the friction clutch and an actuator portion connected to said wear detection portion and operatively arranged relative to said adjusting mechanism for allowing an axial lengthening of said axially acting adjusting mechanism in response to the wear; anda device for securing at least a portion of said axially acting adjusting mechanism against rotation, wherein said device for securing against rotation is operatively connected for securing said second adjusting ring against rotation relative to said pressure plate and comprises a sheet-metal clip fastened to said pressure plate so that it is fixed with respect to rotation relative to said pressure plate and engaging a recess in said second adjusting ring.
