Rubber-sprung rail wheel

A rubber-sprung rail wheel comprising:

• a wheel tire having an inner side and a peripherally-extending web formed on said inner side;
• said peripherally-extending web defining a center plane;
• a wheel rim having an outer side facing toward said wheel tire;
• said wheel rim further including two legs on said outer side and said legs having respective end edges;
• two rubber rings disposed on opposite sides of said web and being laterally delimited by corresponding ones of said two legs;
• each of said end edges and the rubber ring adjacent thereto conjointly defining a transverse plane;
• said inner side of said wheel tire and said transverse plane conjointly defining a first intermediate space;
• said web and said rubber rings having respective end edges facing toward said outer side of said wheel rim;
• said end edges of said web and of said rubber rings facing toward said outer side and said outer side conjointly defining a second interior space;
• said web and said legs being so configured that said rubber rings are arranged inclined with respect to said center plane of said web;
• each of said rubber rings having inner and outer diameters;
• at least one of said rubber rings being subdivided into a first region having a boundary at said inner diameter and a second region having a boundary at said outer diameter and a mid region disposed between said first and second regions;
• and,
• said first and second regions each being conically shaped regions when viewed in section and said mid region having uniform wall thickness.
