ABSTRACT:
The invention relates to a rubber-sprung rail wheel having a wheel tire (1), which has a peripherally-extending web (3) on the inner side (2) thereof, and a wheel rim (4) provided with two legs (6, 7) on the outer side (5) thereof, and two rubber rings (8, 9) that are arranged between the wheel tire (1) and the wheel rim (4). The rubber rings (8, 9) are arranged on both sides of the web (3) and are laterally delimited by the legs (6, 7). A first gap (12) is formed between the inner side (2) of the wheel tire (1) and the end edges (10, 11) of the legs (6, 7) and the rubber rings (8, 9) and a second gap (12) is formed between the outer side (5) of the wheel rim (4) and the end edges (13, 14) of the web (3) and the rubber rings (8, 9). The web (3) and the legs (6, 7) are configured in such a way that the rubber rings (8, 9) are inclined with respect to the central plane of the web (3). According to the invention, the rubber rings respectively have a conically expanded region on the inner diameter (14) and outer diameter (11), and a region having a constant wall thickness between the expanded regions.
