The invention relates to a wheel of a low-floor bogie. The wheel comprises a rim and a tread, wherein the tread consists of four segments of arcs and two segments of straight lines from the inner side to the outer side of the wheel in sequence; the rim consists of a rim inclined line, a wheel back inclined line and a horizontal straight line. Due to optimal design of the tread and the rim, an experiment shows that the wheel greatly reduces abrasion, the guide performance of the wheel is improved, and the service life of the wheel is prolonged; the cost of the wheel and the possibility of climb-on-rail are reduced; furthermore, the wheel serving as an independent wheel more adapts to a groove-shaped rail; two circles of mounting holes are formed in a wheel center and are respectively used for mounting a coupling and a braking disk, so that the wheel can be either used for a low-floor locomotive or used for a low-floor trailer, so that the interchangeability and the universality of the wheel are improved, and the cost is further reduced.
