Abstract

A ball and socket joint assembly for use in motor vehicle suspensions comprises a socket (6) and a spherical head (4) of a ball stud (2) with an interposed open-side bearing (11) and a closed-side bearing (20). The closed-side bearing (20) has a substantially semispherical concave seat surface (25) made up of a radially outer annular curved surface (26) and a radially inner annular curved surface (27). Under normal load, the outer surface (5) of the spherical head (4) is in sliding contact with only the inner surface (27), while under increased load, through resilient deformation of the bearing, both the inner and outer surfaces (26, 27) are brought into contact with the head, whereby small torque is required under normal load and the load withstanding capability is increased under heavy load. The bearings (11) and (20) abut each other whereby the load withstanding capability is further increased. A seal (60) has an interference fit on the socket. Lubricating grooves (32) are formed in the bearing (20). <IMAGE>
