Problems solved by technology

However, this bearing design does not allow radial tolerance compensation
In addition, multiple V-shaped bearings are bound together and become tangled with each other when the body is conveyed, thus creating feeding problems at the pivot assembly line

Embodiment Construction

[0034]The prior art bearing bush 1' shown in FIG. 1 has a cylindrical bush part 1a' and a V-shaped flange 1b' on the axial end of the bush part 1a'. When integrated into a bearing assembly (not shown), the V-shaped flange 1b' of the bearing bush 1' according to the prior art acts as a spring and thus helps to compensate for tolerances in the axial direction. However, radial tolerance compensation is not possible.

[0035] Figure 2a A bearing bush 1 according to the invention is shown. The bearing bush 1 comprises a cylindrical bush portion 1a and a radial flange 1b arranged at the axially upper end of the bush portion 1a. Such as Figure 2a and especially in Figure 2b As can be seen in , flange 1b has a mushroom-shaped cross-section to allow axial or axial and radial tolerance compensation in a bearing assembly, which will be referred to Figure 10 and 11 are described below.

[0036] The mushroom shape causes the flange 1b to act as a spring washer thus compensating the...

Abstract

The invention relates to a bearing bush (1) comprising an essentially cylindrical bush section (1a) and at least one radial flange (1b) arranged on an axial end of said cylindrical bush section (1a). The bearing bush according to the invention is characterized in that the at least one flange (1b) has a mushroom shaped cross section so as to allow axial and radial tolerance compensation in a bearing assembly. Furthermore the invention relates to a bearing assembly and a forming tool for producing a bearing bush.

Description

technical field [0001] The invention relates to a bearing bush comprising a substantially cylindrical bush part and at least one radial flange arranged on an axial end of said cylindrical bush part. Furthermore, the invention relates to a bearing assembly and to an advantageous use of the bearing assembly. Furthermore, the invention relates to an edging tool for producing a flange on a bearing bush. Background technique [0002] Bearing bushes, in particular plain bearing bushes, are widely used in various technical fields, for example in automotive engineering. Specifically, bearing bushings are used in door hinges, pedal linkage systems, shock absorbers, hoods, trunks, and sunroof mechanisms as well as in brake, suspension, and transmission components. Another important application is the use of plain bearing bushes in automotive seat linkages. Those car seat linkages are generally designed with little or no play to allow smooth and noiseless movement of the seat elemen...
