  • Patent number: 4044873
    Abstract: This invention relates to clutch driven plates having an annular component which carries the friction facings and which is mounted for limited rotary movement on a hub so that it extends between a pair of radially extending discs which are fixed to the hub by engagement of serrations formed at their inner peripheral edges in grooves in the hub. The hub has three spaced annular rims which co-operate to form two spaced annular grooves. The two outer rims taper outwardly and the central rim, which is cylindrical, locates a cylindrical spacer which spaces the disc apart. The grooves which receive the serrations are formed in the outer rims. During assembly of the clutch driven plate, the discs are forced axially on to the hub. The grooves are cut by the serrations during assembly and the material that is cut from each rim of the hub by the formation of the grooves is directed into the adjacent annular groove. Once the disc are located against the spacer, the hub is deformed to retain the discs on the hub.
