Abstract

A rubber-metal sleeve bearing includes an inner sleeve, an outer sleeve disposed in concentric relationship to the inner sleeve, and an intermediate sleeve disposed in concentric relationship to the inner and outer sleeves and having first and second elastomer layers to connect the intermediate sleeve to the inner and outer sleeves, respectively. The intermediate sleeve has inner and outer surfaces, each having at least one non-round section, with the non-round section of the inner surface and the non-round section of the outer surface being arranged in offset relationship in a circumferential direction.

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 an axis;
an inner sleeve disposed in concentric relationship to the outer sleeve; and
an intermediate sleeve disposed in concentric relationship to the inner and outer sleeves and having first and second elastomer layers to connect the intermediate sleeve to the inner and outer sleeves, respectively, said intermediate sleeve having inner and outer surfaces, each having at least one non-round section, with the non-round section of the inner surface and the non-round section of the outer surface being arranged in offset relationship in a circumferential direction around the axis.

2. The rubber-metal sleeve bearing of claim 1 , wherein the inner sleeve has an outer surface having at least one non-round section, with the non-round section of the outer surface of the inner sleeve and the non-round section of the inner surface of the intermediate sleeve arranged adjacent to one another in a radial direction.

3. The rubber-metal sleeve bearing of claim 1 , wherein the inner and outer surfaces of the intermediate sleeve have each two non-round sections in opposition to one another.

4. The rubber-metal sleeve bearing of claim 1 , wherein at least one of the inner and outer surfaces of the intermediate sleeve has a spherical configuration, with the non-round section of the inner surface and the non-round section of the outer surface each being configured as flat areas.

5. The rubber-metal sleeve bearing of claim 1 , wherein the inner sleeve has an outer surface of spherical configuration, said outer surface having at least one non-round section which is configured as flat area.

6. The rubber-metal sleeve bearing of claim 1 , wherein the intermediate sleeve is made of plastic.

7. The rubber-metal sleeve bearing of claim 1 , wherein the intermediate sleeve is made by an extrusion process.

8. The rubber-metal sleeve bearing of claim 1 , wherein the inner sleeve and/or the outer sleeve is made of metal.
