Abstract

In a multiple disk clutch, a first clutch disk is located between a flywheel which forms a counter-pressure plate and an intermediate plate and a second clutch disk is located between the intermediate plate, on the opposite side from the first clutch disk, and a pressure-plate. The two clutch disks are attached to an output shaft so that they rotate with but are axially slidable relative to the shaft. The intermediate plate has balance edges each supporting a two-arm lever approximately at its center. The two-arm levers are disposed in planes approximately parallel to the clutch disks and they are arranged to pivot on the intermediate plate about an axis extending radially of the axis of rotation of the clutch. One arm of each lever is connected by a swivel joint to the clutch housing and the other arm is connected by a swivel joint to the pressure plate. A lifting spring prestresses the intermediate plate toward the pressure plate.
