Embodiment Construction

[0035] According to FIG. 1 , a bearing shell 2 is inserted in an annular housing 1 , in which a ball pin 5 with a journal 3 and a joint ball 4 is slidably mounted. In this case, the ball pin 5 protrudes from the ball joint through an opening 6 provided in the bearing shell 2 and can be rotated about the longitudinal center axis 7 of the ball joint and pivoted transversely to this longitudinal center axis in the joint ball 4 Click to turn around. In the region of the opening 6 , the bearing shell 2 bears against the end face of the housing 1 via the outer shoulder 8 , whereas at the end of the bearing shell 2 facing away from the outer shoulder 8 the annular flange 9 extends from the housing 1 . Highlighted.

[0036] It can be seen from FIG. 2 that in order to secure the bearing shell 2 axially in the housing 1 , the annular collar 9 is turned radially outward by material deformation, wherein the turning is preferably effected using an ultrasonic deformation method. The ball ...

Abstract

The invention relates to a ball joint for a motor vehicle, in particular for a oscillating strut of a motor vehicle, the ball joint has a housing (1) open at least on one side, a bearing shell is inserted in the inner cavity of the housing, the bearing shell itself A ball joint that slidingly receives a ball pin. According to a first variant, the inner space has a projection along its inner side, which engages in the bearing shell in a form-fitting manner. Here, the protrusion is a triangular web (13). According to a second variant, the inner space has, along its inner side, a recess into which the bearing shell engages in a form-fitting manner, wherein the recess is an undercut.

Description

technical field [0001] The invention relates to a ball joint for a motor vehicle, in particular for a pivot strut of a motor vehicle, which has a housing which is open at least on one side, in which a bearing shell is inserted, which itself slides A ball joint that accommodates a ball pin. Background technique [0002] DE 43 06 006 A1 discloses a ball joint with an annular housing and a bearing shell inserted into the housing, in which a spherical pin is supported. In this case, the bearing shell has, on its outer circumference, a contour which, in order to prevent a rotational movement about the center axis of the ball pin, engages in a complementary contour of the inner diameter of the housing. [0003] In prior art ball joints, however, it occurs that the profile of the bearing shell loosens from the complementary profile of the housing as the ball joint continues to be used, so that the protection against torsion becomes ineffective. Contents of the invention [0004...
