ABSTRACT:
The invention relates to a ball-and-socket joint which is intended especially for vehicle chassis. The inventive ball-and-socket joint comprises a joint bolt (1) which is provided with a ball joint (1.1), and a plastic joint housing (2) into which a bearing shell (3) is introduced in order to mount the ball joint (1.1) in such a way that it can turn and so that it can tilt within certain limits. The aim of the invention is to ensure that the joint can resist considerable static and dynamic loads in the direction of the joint axis (L) without increasing the cost and to enable the ball joint to be used as a radial joint and as an axial joint. To this end, a metal ring (4) is injected into the joint housing (2). The bearing shell (3) is placed in the joint housing (2) with a positive fit using the end section (4.3) of said ring, which is radially bent inwards and which is located in the area of the opening of the joint housing (2).
