Abstract
The subject of the invention is a ball joint including a stud having a ball head located in a bearing shell made of elastic material. The bearing shell, which exerts a radial pressure on the ball head, is mounted in a joint housing having substantially a pot shape. The bearing shell is provided on its outer surface with elastically deformable elevations, lying against the inner wall of the joint housing. The elevations are arranged on the shell surface of the bearing shell and are formed as ribs and bars extending in the axial direction and arranged alternatively on the shell surface circumference. The bars are separated from the ribs by grooves. The bar width, measured in the circumferential direction, is greater than the width of the ribs. The radial extent of the ribs is greater than that of the bars. The bars thus bear against the joint housing only in the case of large loads acting on the joint.
