Abstract
The subject of the invention is a ball joint for motor vehicles, with two substantially hemispherical bearing shells (4, 5), set between a joint housing (1) and a ball head (3), of which the inner has on its outer side several ridges (8) for support in the joint housing (1). To simplify the mounting of the ball joint and to produce flat lubricant pockets (9) on the inner side of the inner bearing shell (4), it is proposed that the wall thickness (S1) of the inner bearing shell (4), designed in one piece, be greater, in the zone of the ridges (8) than the gap width between the joint housing (1) and the ball head (3), and that the wall thickness (S2), in the zone between the ridges (8), be equal to or less than half the wall thickness (S1) in the zone of the ridges (8), the inner bearing shell (4) being made of a soft-elastic plastic and the outer bearing shell (5 ) being made of a hard-elastic plastic.
