Clutch disc

摘要

In a clutch disc, a flange disc is secured to and projects radially outwardly from an axially extending hub. A friction lining carrier projects radially outwardly from the hub and for a portion of its radial extent it is coextensive with the flange disc. Circumferentially extending springs are seated between stop faces on the flange disc and the friction lining carrier and limit the rotational movement of the carrier relative to the flange disc. Friction members are positioned between the friction lining carrier and the flange disc. One or more contact members are positioned between the friction lining carrier and the flange disc with the contact member being rotatable relative to the friction members. During relative rotation the contact member makes contact with the friction disc and the contacting surface of the contact member extends obliquely of the surface of the friction member so that the axial force applied against the friction member varies in dependence on the extent of relative rotation therebetween.
