Abstract
An intermediate ring includes an annular body with side walls from which cavities extend into the material of the body. The cavities from a web with radially extending web walls, which are inclined with respect to the ring axis. The web is radially relatively rigid, but axially resilient. As a result the intermediate ring retains its shape but can easily adapt to the different shapes of the gaps between the two tires of the wheel set.
Claims4
An intermediate ring for installation between adjacent tires of a plural tire assembly on a vehicle, comprising:
- an annular body having generally flat, axially extending, inner and outer faces and radially extending side faces, said annular body having an axial thickness between said side faces and an axis;
- a plurality of substantially uniformly distributed cavities axially extending inwardly into said annular body from each of said side faces in an alternating manner around said annular body, each of said cavities being located substantially midway between said inner and outer faces and extending axially for a distance greater than one-half of said axial thickness;
- a web between said cavities having radial web walls sloping relative to said axis;
- and
- at least one ring part of solid, uninterrupted material on said annular body.
