ABSTRACT:
The diaphragm spring of the friction clutch is provided with a negative spring property region, for providing a spring force required for engaging the clutch disk between the pressure plate and the flywheel, which progressively diminishes with an increase in a clutch release stroke to a level smaller than a spring force provided by the return spring for the pressure plate. Thus, the reaction force applied to the clutch release assembly at the time of partially engaging the clutch is significantly reduced. In particular, this arrangement is highly suitable for incorporating a wear compensating arrangement which comprises a slide ring assembly which urges a support point of thereof abutting the diaphragm spring toward the pressure plate, and a wear detecting member which is frictionally engaged by the clutch cover and thereby restricts a movement of the support point of the slide ring assembly toward the pressure plate, the frictional force being greater than a normal spring force applied by the diaphragm spring but is smaller than a level of the spring force which will be reached when a wear of the clutch disk has progressed and an operating point of the diaphragm spring has shifted to a point of a higher spring load in the negative spring property region.
