Sealing arrangement between a constant velocity joint and a hub bearing unit of a motor vehicle wheel

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 inner and outer 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 an annular part secured on the wheel hub;
• wherein the radially inwardly projecting flange is axially clamped against a rigid annular part secured to or integral with the hub.
