Abstract

A rubber-metal sleeve bearing includes an outer sleeve having a first outer edge and a second outer edge in opposing relationship to the first outer edge, when viewed in an axial direction. The first and second outer edges each have at least one section provided with radially inwardly recessed outer edge regions. An inner sleeve is disposed in concentric relation to the outer sleeve, and an intermediate sleeve is disposed concentrically between the outer and inner sleeves and connected to the outer sleeve via a first elastomer layer and to the inner sleeve via a second elastomer layer.

First claim

What is claimed as new and desired to be protected by Letters Patent is set forth in the appended claims and includes equivalents of the elements recited therein:

1. A rubber-metal sleeve bearing, comprising:
an outer sleeve having a constant inner diameter and having a first outer edge and a second outer edge in opposing relationship to the first outer edge, when viewed in an axial direction;
an inner sleeve disposed in concentric relation to the outer sleeve having at least one section in the form of a non-round outer surface; and
an intermediate sleeve disposed concentrically between the outer and inner sleeves and connected to the outer sleeve via a first elastomer layer and to the inner sleeve via a second elastomer layer, wherein the intermediate sleeve has outer and inner surfaces, each having at least two non-round sections every 90°, when viewed in a circumferential direction, said non-round sections of the outer and inner surfaces being arranged in offset relation to one another in the circumferential direction, with the non-round sections of the outer surface or the inner surface of the intermediate sleeve being configured to complement the outer edge regions of the outer sleeve, wherein the non-round sections of the inner sleeve and the non-round sections of the inner surface of the intermediate sleeve are oriented adjacent to one another.

2. The rubber-metal sleeve bearing of claim 1 , wherein the outer edge regions have a crescent-shaped configuration.

3. The rubber-metal sleeve bearing of claim 1 , wherein the non-round sections of the outer and inner surfaces of the intermediate sleeve oppose one another, when viewed in a radial direction.

4. The rubber-metal sleeve bearing of claim 1 , wherein at least one of the outer and inner surfaces of the intermediate sleeve is spherical in shape and the non-round sections are each configured as planar surfaces.

5. The rubber-metal sleeve bearing of claim 1 , wherein the outer surface of the inner sleeve is spherical in shape and the non-round sections are each configured as planar surfaces.

6. The rubber-metal sleeve bearing of claim 1 , wherein the intermediate sleeve is produced through an extrusion process.
