Abstract:
1. A torque transmission assembly, comprising first and second structural component parts for coupled engagement to one another for common rotation about an axis of rotation, said first structural component part having a first circumferential toothing and said second structural component part having a second circumferential toothing configured for coupled engagement of said first and second toothing, each of said first and second toothing comprising an axial end area and a plurality of teeth each having an axial end face, wherein the end face of at least one tooth of said first toothing extends axially beyond the end faces of others of said plural teeth of said first toothing, and wherein said end face of said at least one tooth of said first toothing is configured to circumferentially relatively deflect an opposing tooth of the plural teeth of the second toothing so that when the first and second structural component parts are moved relatively together to couplingly engage said first and second toothings and the end face of said at least one tooth of said first toothing is relatively moved into opposition with the end face of said opposing tooth of said second toothing, the configured end face of said at least one tooth of said first toothing deflects the end face of said opposing tooth of said second toothing to effect relative rotation of said first and second toothings and of said first and second structural component parts into coupled engagement of said first and second toothings and of said first and second structural component parts; wherein said first toothing comprises a plurality of said at least one tooth circumferentially distributed about said first toothing; wherein said first structural component part is a driven hub, and said second structural component part is a shaft; wherein said driven hub is the hub of one of a hydrodynamic clutch and a friction clutch arrangement; and wherein said shaft is the shaft of one of a pump shaft for a pressure fluid pump and a supporting shaft; and wherein the axial positions of said end faces of said plural teeth of said plurality of at least one tooth of said first toothing repeat in a substantially regular pattern circumferentially about said first toothing.
