Embodiment Construction

[0038] The ball joint for motor vehicles shown in the figure consists of a housing 1, which is designed here as an annular housing. The housing 1 has an inner cavity 2, which is in Figures 1 to 3 has a circular cross-section in the form of implementation, and in the Figure 4 The illustration of has a polygonal cross-section.

[0039] The bearing bush 3 is installed in the inner cavity 2 of the housing 1 . The bearing shell 3 consists of plastic and is used to mount and support a joint ball 4 , which is generally designated 5 , in a slidingly movable manner. Connect the connecting journal 9 of a spherical shaft head 5 on the joint ball head 4, it, especially by figure 2 It can be seen that a connecting thread 15 is provided for connecting to a vehicle component.

[0040] In addition by figure 2 It can be seen that a rod 14 is fastened to the housing 1 . In this embodiment the rod is integrated with the housing 1 .

[0041] The interior of the housing 1 has an inner s...

Abstract

The invention relates to a ball joint for automobiles, in particular for automobile pendulum struts, which has a housing (1) which is open at least at one end, and a bearing bush (3) is installed in the inner chamber (2) of the housing Inside, the bearing bush itself slidably supports a joint ball (4) of a spherical shaft (5). In this type of ball joint the cavity (2) has protrusions and / or depressions (7) or a polygonal cross-section along its inner shell surface (6) such that there is an interference with respect to the inner shell surface (6). The bearing shell (3) can be inserted into the housing (1) with local plastic deformation of its outer surface. In this case, the inner shell surface (6) has a pressurized area (19) which shortens the effective length of the protrusions and / or depressions.

Description

technical field [0001] The invention relates to a ball joint for a motor vehicle, in particular a ball joint for a pendulum strut of a motor vehicle. Background technique [0002] A ball joint of this type is known, for example, from DE 43 06 006 A1. It has a hollow cylindrical housing, in the inner cavity of which is mounted a bearing shell for slidably supporting the joint ball of a spherical shaft head. The bearing shells of known ball joints of very simple construction consist of plastic, which guarantee optimum frictional properties for the joint ball to be supported. The bearing shell disclosed in said document has a spherical bead which bears on one side on the end face of the housing. An annular flange is formed on the bearing shell on the side opposite the annular bead, which in the preassembled state has an axial length and outer dimensions corresponding to the outer dimensions of the bearing shell relative to the longitudinal center line of the bearing shell. D...
