Abstract
A radial bush bearing, in particular for motor vehicles, includes a cylindrical outer sleeve, a central bush core disposed in and spaced from the outer sleeve defining an annular gap therebetween, at least one elastomer body being fixed in and completely circumferentially filling the annular gap, and hollow conduits with given cross sections penetrating at least a portion of the at least one elastomer body. The hollow conduits have Venturi-like constrictions and also have enlargements with the given cross sections following the constrictions.
Claims21
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.
