The invention relates to the field of railway vehicles, and provides an axle, a wheel set and a railway vehicle. The axle comprises an axle body, and a mounting seat is arranged at the position, close to the inner side of the wheel pair, of the axle body; the fork arm comprises a single-arm end and a double-arm end connected to the single-arm end, the single-arm end is connected to the mounting base, and the double-arm end is used for being connected with the framework. According to the axle, efficient and stable connection between the axle and a framework is achieved, and meanwhile the overall structure and performance of a vehicle are optimized. The mounting base is arranged at the position, close to the inner side of the wheel pair, of the axle body, the single-arm end of the fork arm is connected to the mounting base, the double-arm end of the fork arm is used for being connected with the framework, and therefore the connecting strength between the axle and the framework is remarkably enhanced through the structure. Through the arrangement, the arrangement of an axle box body is omitted, so that the installation steps of the axle, the wheel pair and the framework can be simplified. And unnecessary space occupation is reduced, so that the vehicle design is more compact and efficient, and meanwhile, the loading capacity and the operation efficiency of the vehicle are improved.

    本发明涉及轨道车辆领域,提供一种车轴、轮对及轨道车辆。车轴,包括车轴本体,车轴本体上靠近轮对内侧的位置设置有安装座;叉臂,叉臂包括单臂端以及连接于单臂端的双臂端,单臂端连接于安装座,双臂端用于连接构架。该车轴实现了车轴与构架之间的高效、稳定连接,同时优化了车辆的整体结构和性能。通过在车轴本体上靠近轮对内侧的位置设置安装座,并设计叉臂以单臂端连接于该安装座,而双臂端则用于连接构架,这种结构显著增强了车轴与构架之间的连接强度。通过这样设置,省去了轴箱体的设置,由此即可简化车轴与轮对、构架的安装步骤。减少了不必要的空间占用,使得车辆设计更为紧凑、高效,同时也有助于提升车辆的载重能力和运行效率。
