<p>A bearing assembly for use with a motor vehicle wheel includes an inner sealing ring located within an outer sealing ring, and a constant velocity universal joint located within the inner bearing ring for driving a wheel hub. A contact seal is positioned between the spherical outside surface of the outer joint member of the universal joint and the inside surface of the inner bearing ring. The contact seal extends in the axial direction of the universal joint and has one end fitted into a groove in the inside surface of the inner bearing ring. A plurality of sealing lips extend inwardly from the inner surface of the contact seal into contact with the spherical outside surface of the outer joint member. The lips are spaced apart in the axial direction of the universal joint and extend perpendicularly to the spherical outer surface of the outer joint member. A reinforcing ring laterally encloses the outer surface of the contact seal.</p> |
