The invention provides a wheel set for a gauge-changeable bogie, and relates to the technical field of locomotive production and manufacturing. The wheel set for the gauge-changeable bogie comprises an axle, wheels and a rail changing device, the axle penetrates through the wheels and the rail changing device, the rail changing device comprises an axle box beam, and a locking groove is formed in the axle box beam; the axle box body is arranged in the axle box beam, and a locking protrusion is arranged on the outer wall of the axle box body. The sliding mechanism is arranged outside the axle box body and penetrates through the wheels; the locking mechanism is partially arranged in the axle box beam, and the locking mechanism is arranged between the end, close to the sliding mechanism, of the axle box body and the sliding mechanism. The sliding mechanism is configured to drive the wheels and the locking mechanism to move in the axial direction of the axle, so that the locking protrusions are selectively clamped to the locking grooves, and the locking mechanism selectively abuts against the axle box beam so as to be switched between the unloading unlocking state of the wheels and the bearing locking state of the wheels and used for changing the track gauge of the wheels. Wheel unlocking and unloading are synchronous, wheel locking and bearing are synchronous, the orbital transfer process is simplified, and cost is saved.

    本发明提供一种变轨距转向架用轮对,涉及机车生产制造技术领域。变轨距转向架用轮对,包括车轴、车轮及变轨装置,车轴穿设于车轮和变轨装置,变轨装置包括轴箱梁,轴箱梁内设置有锁紧槽;轴箱体设置于轴箱梁内,轴箱体的外壁设置有锁紧凸起;滑移机构设置于轴箱体的外部并穿设于车轮;锁止机构部分设置于轴箱梁内,锁止机构设置于轴箱体靠近滑移机构的一端和滑移机构之间;滑移机构配置为带动车轮、锁止机构沿车轴的轴向方向移动,使锁紧凸起选择性卡接于锁紧槽,锁止机构选择性抵接于轴箱梁,以在车轮的卸载解锁状态和车轮的承载锁紧状态之间切换,用于车轮变换轨距。车轮解锁与卸载同步,车轮锁紧与承载同步,简化变轨过程,节省成本。
