Abstract

A sleeve bearing for being received in an outer sleeve includes an inner part which extends in the axial direction, a bearing body, and a cage which encloses the bearing body circumferentially. The bearing body encloses the inner part, is made from an elastic material, and has at least two chambers. The cage is formed from at least two cage parts, the spacing of which can be varied in the radial direction. A sealed joint area is provided between the cage parts.

First claim

The invention claimed is:

1. A sleeve bearing for being received in an outer sleeve, comprising:
an inner part which extends in axial direction;
a bearing body enclosing the inner part and having at least two chambers for receiving a damping agent, wherein the bearing body is made from an elastic material;
a cage which encloses the bearing body circumferentially, wherein the cage is formed from at least two cage parts, the spacing of which is able to be varied in radial direction; and
a sealed joint area provided between the cage parts by the elastic material of the bearing body being ejected between the cage parts.

2. A sleeve bearing according to claim 1 , further comprising a front-side chamber cover which covers at least one of the chambers in an axial direction and seals the joint area.

3. A sleeve bearing according to claim 2 , wherein the chamber cover is slotted in the joint area.

4. A sleeve bearing according to claim 1 , wherein the cage parts are connected to each other and are able to move relative to each other via the elastic material.

5. A sleeve bearing according to claim 1 , further comprising joint surfaces which lie opposite each other in the joint area, wherein at least one of the joint surfaces is provided with a seal.

6. A sleeve bearing according to claim 1 , further comprising at least one sealing ring which encloses the cage circumferentially.

7. A sleeve bearing according to claim 1 , wherein the cage parts have ring segment-shaped legs on opposite axial ends of the cage and at a height of the at least two chambers, the chambers being opposite to each other, said legs interacting in a sealing manner.

8. The sleeve bearing according to claim 1 , wherein the cage parts are sealed against each other in their joint area such that hydraulic fluid contained in the sleeve bearing which serves to dampen the bearing cannot exit via the joint area.

9. A sleeve bearing for being received in an outer sleeve, comprising:
an inner part which extends in axial direction;
a bearing body enclosing the inner part and having at least two chambers for receiving a damping agent, wherein the bearing body is made from an elastic material;
a cage which encloses the bearing body circumferentially, wherein the cage is formed from at least two cage parts, the spacing of which is able to be varied in radial direction;
a sealed joint area provided between the cage parts; wherein the cage parts have or form ring segment-shaped legs on opposite axial ends and at a height of the at least two chambers which lie opposite each other, the sealed joint area being provided on free ends of the ring segment-shaped legs.

10. The sleeve bearing according to claim 9 , wherein the at least two chambers are sealed in the sealed joint area.
