Abstract
A friction clutch for use in motor vehicles wherein a clutch plate can be clamped between an engine-driven flywheel and an axially movable pressure plate. The pressure plate is axially movably coupled to the housing of the clutch by a set of leaf springs, and the housing carries a tiltable diaphragm spring which biases the pressure plate toward the clutch plate in engaged condition of the friction clutch. That side of the pressure plate which faces the diaphragm spring carries an elastically deformable insert which is engaged by the diaphragm spring in engaged or disengaged condition of the friction clutch to thus reduce the likelihood of vibration of the pressure plate, particularly when the clutch is disengaged.
