The invention relates to the field of gauge change, and provides a gauge change wheel set and a rail vehicle. The variable gauge wheel set includes an axle, a pair of wheels, a pair of bushings, an outer sleeve and a linkage mechanism; a section of first non-self-locking thread is provided on the inner circumference of the bushing, and a pair of first non-self-locking threads have opposite directions of rotation. A pair of wheels are fastened on a pair of axle sleeves; two sections of the second non-self-locking thread forming a non-self-locking thread pair with the first non-self-locking thread are arranged at intervals on the axle; the wheels are installed on the axle through the axle sleeves, and the second A non-self-locking thread matches the second non-self-locking thread; the outer sleeve is rotatably connected outside the axle, and the linkage mechanism is installed between the axle and the outer sleeve to lock or unlock the rotation of the outer sleeve relative to the axle When the linkage mechanism unlocks the rotation of the outer sleeve relative to the axle and the wheels are in an unloaded state, by pushing a pair of wheels to rotate synchronously, the pair of wheels approach or move away from each other to realize gauge change. The track changing operation of the invention is simple, and the track gauge changing reliability is high.
Description
Technical field[0001]The present invention relates to the field of rail vehicles, in particular, relates to a mission-to-rail distance, and a rail vehicle.Background technique[0002]Transnational passenger transportation has grown rapidly in recent years, but due to differences in railways in various railways, thereby causing serious hindrances to transnational railways. In order to solve the problems of the railway of various railways, the problem of hindering the transnational railway transportation is proposed, and the train distance is proposed, that is, when the train is traveling to the railway of its country, by changing between the wheels on the axle The spacing is to adapt to the rails of the railway.[0003]However, the existing transition distance is complicated to the rail mechanism, and the milestable operation is cumbersome and the reliability is low.Inventive content[0004]The present invention is intended to address at least one of the technical problems present in the p...
