ABSTRACT:
A coupling clutch according to the teachings of the present invention is shown in its most preferred form as including first and second hubs having first and second splined interface discs received thereon. The first interface disc is biased away from the second interface disc and is movable towards the second interface disc by a piston reciprocally mounted to a housing and rotatably mounted to the first interface disc by a bearing mounted therebetween. The splines between the second interface disc and the second hub allow the second interface disc to cant to compensate for axial angular misalignment of the first and second hubs. The housing is further rotatably mounted to the second interface disc. A radially extending, annular lip is provided on the housing which is axially captured between a shoulder and a retaining ring provided on the first hub. Bushing bumpers are provided between the lip and the shoulder and between the retaining ring and the lip. Thus, axial movement of the housing is prevented with respect to the hub. In its most preferred form, the first disc includes a multiplicity of ball-receiving cavities and the second disc includes a carrier member having a multiplicity of balls allowing the same degrees of registry of the first and second discs during clutch activation.
