Abstract

A coupling assembly for connecting a hub bearing unit with a constant velocity joint includes a bell member of a constant velocity joint having a tubular section disposed about a driving ring and having an end surface facing a hub member end surface and an inner circumferential surface defining a bore. The inner surface has inner splines engageable with driving ring outer splines and a tapering surface section. A sealing member is disposed between the hub and bell end surfaces and seals the space between the surfaces. An annular retainer disposed within the bell bore has a tapering outer circumferential surface engageable with the inner surface section of the bore such that the tubular section is retained between the retainer outer surface and the hub end surface, preventing disengagement of the splines and compressing the sealing member between the end surfaces. A connector connects the retainer with the hub.
