ABSTRACT:
A ball joint for motor vehicles comprises a plastic bearing member (2) located between a ball head (1) or a ball and a joint housing (3). The bearing member has a rim flange (9) that lies against an inner step (10) in the joint housing (3). A closing part has an inner surface which lies under a preload against the rim flange (9) and an outer surface engaged by a rolled-in rim (13) of the joint housing (3). The rolling process is thereby simplified and, at the same time, securing of the bearing member against rotation is achieved, while smaller variations of the operational characteristics are attained. To this end, the joint housing (3) has a second inner step (12), displaced radially outward for supporting the inner surface of the rim of the closing part. The distance, in the axial direction of the stud, between the first inner step (10) and the outer step (12) determines the maximum deformation of the rim flange (9) by the closing part lying against the rim flange under preload.
