Abstract

An elastomer joint, in particular for chassis parts of motor vehicles, comprising a housing (6), an elastomer body (2) arranged in the housing (6), and a joint body (1) that is arranged in the elastomer body (2), is characterized in that the housing (6) has a cylindrical inner wall, and a spacer (4) is provided that is arranged at an axial end of the elastomer body (2) between the latter and the inner wall.

Claims

1. An elastomer joint, in particular for chassis parts of motor vehicles, comprising a housing, an elastomer body arranged in the housing, and a joint body that is arranged in the elastomer body, wherein the housing has a cylindrical inner wall, and a spacer is provided that is arranged at an axial end of the elastomer body between the latter and the inner wall.

2. The elastomer joint according to claim 1, wherein a support ring is arranged at the elastomer body, and the spacer is arranged at the support ring.

3. The elastomer joint according to claim 2, wherein the spacer and the support ring are one piece.

4. The elastomer joint according to claim 3, wherein the spacer is designed as an encircling collar on the support ring.

5. The elastomer joint according to claim 4, wherein the collar is provided with a chamfer so that a gentle transition is achieved to the inner wall of the housing.

6. The elastomer joint according to claim 1, wherein the spacer is an insert part having an L-shaped cross-section that encompasses the support ring.

7. The elastomer joint according to claim 6, wherein adjacent to the spacer, a transition element is arranged that has a wedge-shaped cross-section.

8. The elastomer joint according to claim 7, wherein the transition element is made of plastic.

9. The elastomer joint according to claim 6, wherein the spacer is adjacent to a split washer that engages in a groove of the housing.
