  • Patent number: 4356901
    Abstract: An improved support is for a series of friction discs within a housing of a clutch, brake or the like of the type which includes a central member mounted for rotation relative to the housing. A series of reaction discs are alternatively disposed between the friction discs and are mounted for relative rotation with the central member. Each friction disc includes a plurality of generally axially extending tabs which are received within a plurality of slots in the adjacent friction disc to prevent relative rotation between the friction discs. A slot in a portion of the housing adjacent the last friction disc in the series receives the tabs thereof to prevent relative rotation of the entire series with respect to the housing. Axial force being applied to the series of friction discs and reaction discs produces frictional forces therebetween tending to reduce relative rotation of the housing and central member.
