Abstract
An elastomer bearing, includes a cylindrical inner metal part, a metallic outer sleeve arranged at a radial distance around the inner metal part; and an elastomer part arranged between the inner metal part and the metallic outer sleeve. The elastomer part has an outer sheath provided with a plastic layer. The outer sleeve is constructed as a one-piece extruded part made of lightweight metal, and the outer sleeve has an inner sheath surface provided with a profiling which form fittingly engages in the plastic layer.
Claims21
An elastomer bearing, comprising:
- a cylindrical inner metal part,
- a metallic outer sleeve arranged at a radial distance around the inner metal part;
- and
- an elastomer part arranged between the inner metal part and the metallic outer sleeve, said elastomer part having an outer sheath provided with a plastic layer, the outer sleeve being constructed as a one-piece extruded part made of lightweight metal, the outer sleeve having an inner sheath surface provided with a profiling which form fittingly engages in the plastic layer.
A method for producing an elastomer bearing, comprising:
- providing a cylindrical inner metal part, an elastomer part having a plastic layer on its outer sheath surface, and an outer sleeve, which is produced as one-piece extruded part from lightweight metal;
- pre-treating a surface of the cylindrical inner metal part;
- bringing the elastomer part into contact with the inner metal part;
- joining the elastomer part with the inner metal part with an adhesive or by vulcanizing;
- and
- pressing the outer sleeve onto the elastomer part during or after the joining, so that a profiling of an inner sheath surface of the outer sleeve comes into form fitting engagement with the plastic layer.
