ABSTRACT:
To improve the corrosion protection at the connection site of the sealing cuff and the ball pivot, it is proposed, in a design in which the sealing cuff engages with an edge profile in a complementary profile of a retaining ring rigidly attached to the ball pivot, that at least the part (12) of the retaining ring (10) which is supported by the edge of the bearing lug (6) consists of a material whose value in the electrochemical series is lower than that of the material of the bearing lug (6) and of the ball pivot (2). By this construction the material of the retaining ring acts as an electrolytic sacrificial anode.
