The invention relates to the field of variable gauges of railway vehicles, and provides an outer sleeve for a variable gauge wheel set, the variable gauge wheel set and a railway vehicle. The outer sleeve for the gauge-changeable wheel set is arranged outside an axle of the gauge-changeable wheel set in a sleeving mode, at least one first roller path is arranged in the inner periphery of the outersleeve, and inner splines are arranged at the positions, located in the two axial sides of the first roller path and spaced from the first roller path by a set distance, in the outer sleeve. The outer sleeve is ingenious in structural design, so that the connection structure of the axle and the wheels is simple, and the gauge-changeable reliability is high.

    本发明涉及轨道车辆变轨距领域,提供变轨距轮对用外套筒、变轨距轮对及轨道车辆。该变轨距轮对用外套筒用于套设在变轨距轮对的车轴外,所述外套筒的内周构造有至少一个第一滚道,所述外套筒内位于所述第一滚道的轴向两侧且距离所述第一滚道设定间距处分别设有内花键。本发明的外套筒结构设计巧妙,使得车轴与车轮连接结构简单,变轨距可靠性高。
