CLUTCH DRIVEN PLATE ASSEMBLY WITH MULTI-PART HUB

摘要

CLUTCH DRIVEN PLATE ASSEMBLY WITH MULTI-PART HUB : A clutch driven plate assembly (10) for use in an automotive vehicle having a multi-part hub assembly (11) with the capability of trapping lubricant in the gear teeth when the assembly is subjected to centrifugal force in operation. The hub assembly includes an inner hub (34) in axial splined engagement with the transmission input shaft (12), an outer hub (41) with an integral radial flange (49) and in splined engagement with the inner hub through helical splines (37,43). The inner hub is formed of a light weight non-metallic material, or the outer hub houses an annular spacer formed of an impact and sound-absorbing material to cushion the inner hub upon reciprocation thereof within the outer hub, the outer hub having end plates which act as a dam for lubricant within the intermeshing helical gear teeth.
