ABSTRACT:
In a frictional clutch assembly a diaphragm spring is supported by the clutch housing and engages a pressure plate such as to urge the pressure plate towards a driving member and effect frictional engagement of a clutch disc between the pressure plate and the driving member. The diaphragm spring is provided with radially extending slots extending from the radially inward edge of the diaphragm spring in radial outward direction. Tongues are provided between subsequent slots. The tongues are engaged by a clutch release unit for lifting the diaphragm spring from the pressure plate in view of disengagement operation of the clutch assembly. In view of reducing the length of the necessary clutch disengagement path of the radially inner ends of the tongues to be effected by the clutch release unit alternating tongues are deflected in opposite axial directions and a spacer assembly is provided between a first group of tongues deflected in a first axial direction and a second group of tongues deflected in a second axial direction.
