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 they rotate with but are axially slidable relative to the shaft. A spring acting on the intermediate plate lifts the intermediate plate when the clutch is disengaged. A lifting distance limitation device is associated with the intermediate plate and limits its lifting distance. The limitation device includes a self-acting readjustment device which readjusts the lifting distance as a function of the wear on the friction linings of the first clutch disk. A spring member extends between the intermediate plate and the pressure plate and acts on the intermediate plate in the engagement direction when the clutch is being engaged.
