Friction facing material and carrier assembly.

摘要

A friction material and carrier assembly 2 (which is to be used in the construction of a driven plate of a dry friction clutch) comprises a carrier plate 4 having radially extending spokes or paddles l4 which are elastically pliable axially of the carrier plate. Two annular friction facings 20 and 22 which are resilient and capable of flexing are bonded by respective layers 24 of silicone rubber to opposite sides of the paddles. Each rubber layer 24 can be formed by strips or beads of rubber for example the layer bonding facing 22 to the paddles consists of annular strips 24A, 24B, 24C, 24D and 24E. The paddles l4 arrangement is capable of sinuous flexing circumferentially of the assembly 2, 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 l4 and rubber layers 24 and the friction facings 20 and 22 is reduced by between 0.05 mm and 2.00 mm.
