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.

A coupling clutch comprising, in combination: a first hub for receipt of a first shaft in a non-rotatable condition; a second hub for receipt of a second shaft in a non-rotatable condition; a first disc; means for slideably mounting the first disc on the first hub; means for biasing the first disc in a first axial direction towards a first axial position on the first hub; means for moving the first disc in the opposite axial direction towards a second axial position; a second disc, with the second disc being selectively engageable with the first disc to rotatably relate the first disc and the second disc; means for slideably mounting the second disc on the second hub; and means for substantially preventing slideable movement of the second disc with respect to the second hub and for allowing canting of the second disc with respect to the second hub to take up angular misalignment of the first and second shafts; with the means for slideably mounting the first disc on the first hub comprising, in combination: crown splines formed on the first hub; and splines formed in the first disc complementary to and for slideable receipt on the crown splines of the first hub; with the means for slideably mounting the second disc on the second hub comprising, in combination: crown splines formed on the second hub; and splines formed in the second disc complementary to and for slideable receipt on the crown splines of the second hub, wherein the crown splines on the hubs allow further canting of the discs with respect to the hubs to take up considerable more angular misalignment of the first and second shafts with the substantially equal rotational backlash.
