Clutch driven plate assembly with a floating hub

A clutch driven plate assembly for an automotive vehicle clutch driving a transmission input shaft, comprising a multi-part hub assembly including an inner hub operatively connected to the transmission input shaft, an outer hub encompassing said inner hub and having an integral radial flange operatively connected to friction facings located between a engine flywheel and a clutch pressure plate, said inner hub having a radial flange at one end and a stop ring adjacent the opposite end, said radial flange having a surface facing the outer hub flange, a back plate positioned on said inner hub adjacent said stop ring, a plurality of intermeshing camming surfaces formed on the flange surface and facing surface of the outer hub so that relative rotation betwen the hubs will result in axial motion of the inner hub on the transmission shaft, and resilient means between said back plate and outer hub to yieldably bias the camming surfaces into engagement.
