Elastic wheel for subway vehicle

The invention discloses an elastic wheel for a subway vehicle. The elastic wheel comprises a wheel rim (1) and a wheel core (4), and is characterized in that a rubber layer (2) with the bowl-shaped cross section is embedded between the wheel rim (1) and the wheel core (4) in an interference way; the width of the rubber layer (2) is smaller than the width of the wheel rim (1); the wheel core (4) is provided with an installing groove at the outer side of the rubber layer (2); an installing ring (3) and the installing groove are in interference fit; a screw bolt (5) passes through the installing ring (3) and the rubber layer (2), and is then connected with the inner side of the wheel core (4) through screw threads. The elastic wheel has the advantages that the structure is simple; the proper radial and axial rigidity is realized; the noise reduction and vibration isolation effects are good; the safety is high. 本发明公开了种地铁车辆用弹性车轮，包括轮辋(1)、轮心(4)，其特征在于：所述的轮辋(1)与轮心(4)之间过盈嵌合有截面呈碗型的橡胶层(2)，且橡胶层(2)的宽度小于轮辋(1)的宽度(4)；所述的轮心(4)
