Abstract:
A motor-vehicle clutch, comprising:a clutch housing rotatably mounted about an axis of rotation;a pressure plate rotatably mounted about said axis of rotation for rotation about said axis of rotation with said clutch housing and axially movably mounted for axial movement relative to said clutch housing, said pressure plate having protrusions projecting from a side of said pressure plate facing said clutch housing, and said protrusions having bearing surfaces arranged parallel to a plane of rotation of said pressure plate;a diaphragm spring supportably arranged between said clutch housing and said pressure plate for urging said pressure plate against a clutch disk; andan adjustment ring arranged between said diaphragm spring and said pressure plate having first and second supporting surfaces arranged parallel to said plane of rotation of said pressure plate, said first and second supporting surfaces being connected by an oblique surface so that said first supporting surface is at a different axial distance from said pressure plate than said second supporting surface, said bearing surfaces of said pressure plate selectively abutting one of said first and second supporting surfaces, wherein said adjustment ring is rotatable relative to said pressure plate and manually adjustable between a first position wherein said first supporting surfaces bear against said bearing surfaces and a second position wherein said second supporting surfaces bear against said bearing surfaces.
