ABSTRACT:
A friction plate for a vehicle clutch assembly having an improved damper spring. The damper spring includes a compression coil spring member which is encapsulated within an elastomer. The elastomer fills the interior of the spring and the spaces between the individual spring coils. The spring-elastomer combination has a greater dampening effect than the total dampening effect of the spring and elastomer if acting independent of each other. A plurality of the encapsulated springs are mounted individually in axially aligned openings provided in an inner hub flange, a friction drive plate and a retainer plate, all of which are mounted concentrically with respect to each other, with the hub flange being integral with a clutch hub. The encapsulated spring rotatably couples together the friction drive plate and retainer plate with the hub. Friction elements are mounted on the outer periphery of the drive plate. The encapsulated spring absorbs the shock and reduces chatter upon the friction elements coupling engaging another clutch member, and transmits the coupling drive forces between the drive plate and hub.
