Patent ID: 7213696

Claim:
A friction clutch arrangement for a motor vehicle, said arrangement comprising: a clutch housing which can be fixed to a flywheel and can rotate about an axis of rotation; at least one pressure plate which is fixed against rotation with respect to said clutch housing and can move axially with respect to said clutch housing; at least one clutch disk which can be fixed against rotation with respect to a shaft, can rotate with respect to said clutch housing, and can engage a respective at least one pressure plate to transmit torque from said clutch housing to said shaft; a clutch spring arranged on said clutch housing and loading said at least one pressure plate axially toward said flywheel with a pressing force via a first force action point; a disengagement device comprising a sliding sleeve which is mounted concentrically on said shaft, and a first disengagement ring arranged on said sliding sleeve and operatively connected to said clutch spring at a second force action point, said sliding sleeve being axially displaceable on said shaft to introduce a disengagement force to said clutch spring via said second force action point, thereby producing a characteristic curve of disengagement force versus disengagement travel of said sleeve; and a compensation device which, during disengagement of said clutch, introduces a compensation force counter to said pressing force in a predefined section of said characteristic curve, thereby reducing said disengagement force in said predefined section, wherein said compensation device comprises a compensation spring arranged in a force transmission path between the clutch spring and the sliding sleeve.
