Abstract
The subject of the invention is a ball joint for motor vehicles with a bearing shell arranged between a joint housing and a ball head. The shell is provided at one end with elastically deformable ribs projecting from a stop surface. So that the ribs, after compensating for production tolerances, can absorb, in the elastically deformable zone, additional axial shock loads occurring in driving operation, it is proposed that the ribs be designed as square ribs, running radially, and separated by grooves from the stop surface adjoining their side walls, while the volume of each rib projecting above the stop surface, before mounting, is approximately equal to the free volume of the two grooves adjacent to it, so that the side walls of the grooves lying next to the stop surface act in the mounted condition as support walls for the elastically deformed ribs.
