Claims
- 1. A radial bush bearing, comprising a cylindrical outer sleeve defining an axial direction, a central bush core disposed in and spaced from said outer sleeve defining an annular gap therebetween, at least one elastomer body being fixed in and completely circumferentially filling said annular gap, said elastomer body being subject to radial compression as a major component of force acting on the radial bush bearing, and hollow conduits with given cross sections penetrating said at least one elastomer body in the axial direction, said hollow conduits being formed directly in said elastomeric material and having Venturi-like constrictions and smoothly merging transitions from regions with said given cross sections to said Venturi-like constrictions and smoothly merging transitions following said constrictions, wherein, when said elastomer body is radially compressed, said constrictions come into mutual contact first and, upon further compression, said hollow conduits collapse as well.
- 2. The radial bush bearing according to claim 1, wherein the bush bearing has a bush axis, and said hollow conduits extend parallel to the bush axis and penetrate the entire length of said at least one elastomer body.
- 3. The radial bush bearing according to claim 2, wherein said axially parallel conduits are disposed at a uniform mutual spacing on a cylindrical surface in said at least one elastomer body.
- 4. The radial bush bearing according to claim 3, wherein said at least one elastomer body has outer and inner peripheries being vulcanized onto said sleeve and said bush core.
- 5. The radial bush bearing according to claim 2, wherein said axially parallel conduits are radially spaced apart by different distances from the bush axis.
- 6. The radial bush bearing according to claim 5, wherein said at least one elastomer body has outer and inner peripheries being vulcanized onto said sleeve and said bush core.
- 7. The radial bush bearing according to claim 2, wherein said axially parallel conduits are spaced apart from one another with a variable meridial spacing.
- 8. The radial bush bearing according to claim 7, wherein said at least one elastomer body has outer and inner peripheries being vulcanized onto said sleeve and said bush core.
- 9. The radial bush bearing according to claim 2, wherein said at least one elastomer body has regions of lesser and regions of greater radial rigidity, and said axially parallel conduits have larger diameters in said regions of lesser radial rigidity.
- 10. The radial bush bearing according to claim 2, wherein said at least one elastomer body has an inner periphery being vulcanized onto said bush core, and said outer sleeve is axially pressed on said at least one elastomer body.
- 11. The radial bush bearing according to claim 2, wherein said at least one elastomer body has an outer periphery being vulcanized onto said sleeve, and said bush core is pressed into said at least one elastomer body.
- 12. The radial bush bearing according to claim 2, wherein said at least one elastomer body is fully vulcanized separately and is subsequently injected into said annular gap between said outer sleeve and said bush core.
- 13. The radial bush bearing according to claim 1, wherein said hollow conduits extend radially in a plurality of radial planes in said at least one elastomer body and terminate flush in said at least one elastomer body at a distance from said bush core.
- 14. The radial bush bearing according to claim 1, wherein said at least one elastomer body has axially parallel conduits and radial conduits ending between said axially parallel conduits.
- 15. The radial bush bearing according to claim 1, wherein said at least one elastomer body has regions of lesser and regions of greater radial rigidity, said axially parallel conduits are mutually spaced apart by a relatively smaller distance in said regions of lesser radial rigidity, and said axially parallel conduits are mutually spaced apart by a relatively larger distance in said regions of greater radial rigidity.
- 16. The radial bush bearing according to claim 1, wherein said at least one elastomer body is two axially disposed elastomer bodies, and including a radial collar disposed between said elastomer bodies and said bush core as a radial stop.
- 17. The radial bush bearing according to claim 16, wherein said radial stop has a smaller radial height than said elastomer bodies and has an outer periphery with an elastic covering disposed thereon.
- 18. The radial bush bearing according to claim 17, wherein said radial stop is also constructed as an axial stop.
- 19. The radial bush bearing according to claim 1, wherein said at least one elastomer body is constructed in one piece and has two ends, and including collars each being disposed as a radial stop on a respective one of said ends of said elastomer body.
- 20. The radial bush bearing according to claim 19, wherein said collars have a smaller radial height than said elastomer body and outer peripheries with elastic coverings disposed thereon.
- 21. The radial bush bearing according to claim 20, wherein said collars are also constructed as axial stops.
