A friction facing material and carrier assembly (2) for inclusion in a clutch driven plate. The assembly (2) comprises a metal carrier plate (4) having resiliently pliable spokes or paddles (14) at its outer periphery. Two annuli (20,22) of friction material forming friction facings are bonded to opposite sides of the paddles (14) by a respective layer of an elastomeric material, for example a silicone rubber. Each elastomeric layer is in the form of a spiral stripe extending substantially continuously from the outer to the inner periphery of the respective friction facing. For example, the facing (22) is bonded by an elastomeric spiral having three turns 24A, 24B and 24C. Preferably in a complete assembly (2), both spirals of elastomeric material are of the same hand with turns of one spiral opposite gaps between adjacent turns of the other spiral. |
