Abstract

The present disclosure relates to a bearing arrangement having a bearing bush and a rubber/solid bearing which is inserted into the bearing bush with an outer sleeve and an elastomer material which is arranged therein. The bearing bush has inwardly pointing projections, and depressions are configured in the outer sleeve, into which depressions the projections engage.

First claim

The invention claimed is:

1. A bearing arrangement, comprising:
a bearing bush,
a solid bearing having an outer sleeve and an elastomer material arranged in the bearing bush, and
inwardly pointing projections in the bearing bush that engage depressions in the outer sleeve,
wherein each of the projections is arranged offset with respect to another of the projections in an axial direction and in a radial direction, and
wherein each of the depressions is arranged offset with respect to another of the depressions in the axial direction and in the radial direction.

2. The bearing arrangement according to claim 1 , wherein each of the projections has a length in the axial direction from 0.1 to 0.3 times shorter than a length of each of the depressions.

3. The bearing arrangement according to claim 1 , wherein, in a push-in direction, the depressions have a first bevel arranged at an angle from 20° to 40° with respect to an outer circumferential face of the outer sleeve.

4. The bearing arrangement according to claim 3 , wherein each of the projections engages the circumferential face of the bearing bush at an angle (δ) from 1° to 30°.

5. The bearing arrangement according to claim 1 , wherein the bearing bush is arranged so that a direction of force is applied in the radial direction of the solid bearing, and no projections and depressions are arranged in an angular region of +45° and −45° with respect to the direction of force, and no depressions and projections are arranged on a side that is opposite to the angular region in the radial direction.

6. The bearing arrangement according to claim 1 , wherein the solid bearing has an inner sleeve.

7. The bearing arrangement according to claim 1 , wherein the outer sleeve comprises a plastic material.

8. The bearing arrangement according to claim 1 , wherein the bearing bush comprises a metallic material.

9. The bearing arrangement according to claim 1 , wherein each of the projections is arranged as a latching tongue or a latching lip which is oriented into an interior space of the bearing bush.

10. The bearing arrangement according to claim 1 , wherein the bearing bush has a widened portion at one end.

11. The bearing arrangement according to claim 1 , wherein the outer sleeve has an outwardly projecting collar at one end.

12. The bearing arrangement according to claim 1 , wherein each of the projections has a length in the axial direction from 0.15 to 0.25 times shorter than a length of each of the depressions.

13. The bearing arrangement according to claim 1 , wherein, in a push-in direction, each of the depressions has a second bevel arranged at an angle from 40° to 60° with respect to an outer circumferential face of the outer sleeve.

14. The bearing arrangement according to claim 1 , wherein the bearing bush is a motor vehicle component.

15. The bearing arrangement according to claim 1 , wherein the solid bearing comprises a rubber material.
