Claims11
A flexible member for rubber-sprung rail wheels with first and second concentric parts and with an annular gap between them, comprising:
- a rubber member adapted to fit in said annular gap;
- a current bridge;
- and
- an opening through said rubber member, wherein said opening is adapted to receive said current bridge, wherein said opening has an oval cross-section when said rubber member is in an unstressed state.
A rubber-sprung rail wheel, comprising:
- a wheel rim;
- a wheel tire disposed concentrically outside of said wheel rim;
- at least one rubber member disposed in an annular gap between said wheel rim and said wheel tire, wherein said rubber member has an opening through said rubber member, wherein said opening is adapted to receive a current bridge, wherein said opening has an oval cross-section when said rubber member is in an unstressed state;
- and
- a current bridge residing in said opening.
A rubber member for rubber-sprung rail wheels with first and second concentric wheel parts and with an annular gap between them, comprising:
- a rubber member disposed under prestressing in said annular gap between said first and second concentric wheel parts, said robber member having opposite outer bearing faces;
- a current bridge;
- and
- an opening provided between said outer bearing faces bearing against said wheel parts and said current bridge disposed in said opening;
- wherein said opening has an oval cross-section when said rubber member is in an unstressed state.
