The invention belongs to the technical field of railway vehicles, and particularly relates to a wheel set assembly and a gauge-changeable bogie. The wheel set assembly comprises an axle, two wheels and two locking mechanisms, wherein the locking mechanisms correspond to the wheels in a one-to-one mode, the two wheels are oppositely arranged at the two axial ends of the axle through the corresponding locking mechanisms respectively, and the distance between the two wheels and the axle can be changed by operating the locking mechanisms. According to the gauge-changeable bogie, during gauge changing, the friction between the wheels and the axle is mainly between the sliding sleeves and the positioning bushings, part replacement repair is adopted during maintenance, the use state of the wheelset can be rapidly recovered, and the maintenance efficiency is improved; all the abrasion parts can be separated into independent accessories and can be independently replaced according to conditionsin the overhauling process, the maintenance cost is reduced, in addition, labeling operation can be carried out in the rail changing process, and good practicability is achieved.
本发明属于铁路车辆技术领域,尤其涉及一种轮对组成以及变轨距转向架。其中的轮对组成包括车轴、两个车轮以及两个锁定机构,锁定机构和车轮一一对应,两个车轮分别通过对应的锁定机构相对设置在车轴的轴向两端上,通过操作锁定机构,可使两个车轮在车轴之间的距离改变。本发明所示的一种变轨距转向架,在变轨时,车轮和车轴之间的摩擦主要为滑动套和定位衬套之间,维修时采用换件修,可迅速恢复轮对使用状态,提高维修效率;且各磨耗件均可分离成单独配件,检修时可根据情况单独更换,降低维修成本,另外,变轨时的操作可以标注化作业,具有很好的实用性。
