  • Patent number: 4537296
    Abstract: The clutch driven plate assembly includes a hub assembly connectable to a driven shaft and interconnected driven and spring retainer plates rotatably mounted upon the hub assembly. The hub assembly has an inner hub and an outer hub having a driven flange between the plates. A plurality of circumferentially spaced aligned windows are provided in the plates and flange, with at least one compression spring retained within each set of aligned windows thereby defining a yieldable connection between the plates and flange. The inner hub has a cylindrical body provided with a pair of outwardly directed converging hub flanges and the outer hub has a central opening of the same shape as the hub flanges and oversized with respect thereto and loosely receiving the inner hub flanges for limited relative rotation. A back plate is spaced from the inner and outer hubs and secured to the flange, and a resilient spacer is interposed between and bears against the inner and outer hubs and back plate.
