Friction clutch driven plate

摘要

A friction clutch driven plate has an internally splined hub, and externally a circular radial flange to rotate with the hub about the hub axis. The flange has teeth in its outer periphery which are in driving meshed engagement with teeth in the inner periphery of an annulus of friction material. That annulus is formed by separate successive arcuate sections or sectors of friction material. The sections of friction material can, axially of the hub, each move relatively to one another by a limited amount to improve the axial compliance of the friction annulus when in a clutch and clamped between a drive plate and a pressure plate. A holding strap extends around the outer periphery of the annulus to hold the sections thereof on the flange against centrifugal force.
