ABSTRACT:
A friction material and carrier assembly (which is to be used in the construction of a driven plate of a dry friction clutch) comprises a circular carrier plate having at its periphery radially extending spokes or paddles which are elastically pliable axially of the carrier plate. Two annular friction facings which are resilient and capable of flexing are bonded by respective layers of silicone rubber to opposite sides of the paddles. Each rubber layer can be formed by a plurality of strips or beads of rubber. The paddles arrangement is capable of sinuous flexing circumferentially of the assembly, and when the assembly is in a driven plate in a clutch applying the clamp load specified for the clutch, the overall axial thickness of the combination formed by the paddles and rubber layers and the friction facings is reduced by between 0.05 mm and 2.00 mm.
