Abstract
The subject of the invention is an adjustable fastening of a ball joint (2) to a tie rod (1) for steering linkages of motor vehicles, with a ball-ended wrist pin (12) movable in all directions located in a universal joint housing (14), which is arranged in a fastening plate (16) with a bearing hole (18), a fastening element (screw 22) fixed on the tie rod, which passes through the bearing hole (18), so that the fastening plate (16) is supported swiveling around the fastening element (screw 22) and a locking element engaging with the fastening plate (16) for fixing of the ball joint (2) in a defined swiveled position. A fastening of this type which is adjustable simply and without special tools, has a low construction cost and nevertheless offers sufficient safety against an unintentional adjustment of the fastening during operation, is created by the fact that the locking element is a threaded joint (30), which is arranged perpendicular to axis (31) of the fastening element (screw 22) and engages with the gear-tooth system (19) arranged on the fastening plate (16).
