ABSTRACT:
A knuckle or swivel joint of the half-ball and socket type comprising a stud terminating in an enlarged diameter half-ball member disposed in the socket member and having a hemispherical recess engaged by the hemispherical convex surface of a retainer bearing member disposed in or, alternatively, made integral with the socket member. The retainer bearing member or, alternatively, a segment of the socket internal surface engaged with the half-ball peripheral surface is elastically pre-loaded in an appropriate direction which causes firm engagement of the diverse bearing surfaces in mutual contact, thus, among others, compensating for wear. The knuckle or swivel joint assembly of the invention is capable of transmitting substantial loads within a wide range of angular variations between the stud and the shank, or other member, rigidly connected to the socket.
