Abstract
A friction clutch having a counter-pressure plate and a pressing plate that is rotationally fixed and axially movable in relation to the latter, a cover part which is firmly connected to the counter-pressure plate, a lever spring clamped between the pressing plate and cover part having an encircling power rim and levers extending radially inward and distributed around the circumference and support zones extending radially outward, a clutch plate having friction linings which may be brought into frictional engagement between the counter-pressure plate and the pressing plate dependent on an axial engaging force applied to the levers contrary to the effect of a lining resiliency, a compensation spring effectively countering the lining resiliency between the counter-pressure plate and the pressing plate, and an adjusting device having a drive spring in the form of an opened ring situated on the lever spring.
