Abstract:
1. A sealing arrangement between a hub bearing unit for a motor vehicle wheel and an associated constant velocity joint, the hub bearing unit comprising a rotatable hub to which a driving ring is fixed for providing torque transmission to the hub from an outer, rotatable bell member of the constant velocity joint, the bell member having a tubular projection in telescopic relation with the driving ring, and a radial slot axially extending to an end side of the bell member facing a rotatable member of the hub beating unit, the driving ring and the tubular projection having respective outer and inner circular grooves accommodating a spring locking ring for releasably axially securing the joint bell to the driving ring, the locking ring having arms extending radially outwardly through the slot, a resilient sleeve being fitted with a first end thereof on an outer surface on the tubular projection, the radial slot and the arms of the spring locking ring being covered from the outside, a second other end of the sleeve having a radially inwardly projecting annular flange sealingly cooperating with a rigid annular part secured to or integral with the wheel hub; wherein the radially inwardly projecting flange is axially clamped against the rigid annular part.
