Abstract

A rubber elastic bearing for securing a drive unit in a motor vehicle in an uncoupled manner. The bearing can be assembled between as housing of a drive unit and a support component, and the bearing can be held at least indirectly in the support component in a form-fitting manner. A joining aid for the bearing is provided such that a secure joint of the form-fitting connection with the support component can be achieved.

First claim

The invention claimed is:

1. A rubber-elastic bearing configured for decoupled fastening of a drive unit, in a motor vehicle, the rubber-elastic bearing comprising:
a closed recess; and
an interlocking connection configured to interlockingly hold the rubber-elastic bearing in a carrier component, wherein the rubber-elastic bearing is installed between a housing of the drive unit and the carrier component, wherein the interlocking connection is formed by a joining aid,
wherein the joining aid extends into the closed recess at least in regions,
wherein the joining aid ends at a distance from one end of the recess, wherein the distance corresponds to an elasticity of the rubber-elastic bearing such that elasticity of the rubber-elastic bearing is not restricted by the joining aid to allow maximal deformation of the rubber-elastic bearing, wherein the joining aid further ends within the recess at a second distance from the interlocking connection, wherein a side wall of the joining aid is spaced from an inner side wall of the rubber-elastic bearing defining the recess.

2. The rubber-elastic bearing according to claim 1 , wherein the rubber-elastic bearing has indentations at least in regions, wherein the recess extends into a region of the indentation.

3. The rubber-elastic bearing according to claim 1 , wherein a geometric shape of an end of the recess cooperates with a corresponding geometric shape of the joining aid.

4. The rubber-elastic bearing according to claim 1 , wherein the rubber-elastic bearing is deformable.

5. The rubber-elastic bearing according to claim 1 , wherein the rubber-elastic bearing is mounted in the housing between a first housing part and a second housing part.

6. The rubber-elastic bearing according to claim 5 , wherein the joining aid is integral with the second housing part.

7. The rubber-elastic bearing according to claim 1 , wherein the joining aid is integral with the rubber-elastic bearing.

8. The rubber-elastic bearing according to claim 1 , wherein the rubber-elastic bearing has a connection element.

9. The rubber-elastic bearing according to claim 2 , wherein the indentations are radial grooves.

10. The rubber-elastic bearing according to claim 8 , wherein the connection element has an accordion shape.

11. The rubber-elastic bearing according to claim 8 , wherein the connection element has a stepped hollow-cylindrical profile.

12. The rubber-elastic bearing according to claim 8 , wherein the connection element surrounds the joining aid.

13. The rubber-elastic bearing according to claim 1 , wherein the joining aid has a tapering shape toward the carrier component.

14. The rubber-elastic bearing according to claim 1 , wherein the rubber-elastic bearing and the joining aid are symmetrical.

15. The rubber-elastic bearing according to claim 1 , wherein the rubber-elastic bearing has an annular groove that circumferentially surrounds a bore formed in the carrier component.

16. The rubber-elastic bearing according to claim 15 , wherein the rubber-elastic bearing has a joining region that receives an axial end of the joining aid, the joining region being configured to enable play of the axial end without impairing elasticity of the rubber-elastic bearing.

17. The rubber-elastic bearing according to claim 1 , wherein an axial end of the joining aid is spaced from an axial end of the rubber-elastic bearing that is proximate the axial end of the joining aid when the joining aid is inserted in the rubber-elastic bearing.

18. The rubber-elastic bearing according to claim 8 , wherein the connection element has a hollow-cylindrical profile, wherein the joining aid has a cylindrical profile, and wherein the entire circular wall of the joining aid is spaced from the interior wall of the connection element.
