Abstract

The invention relates to the field of variable gauges, and provides a variable gauge wheel set and a rail vehicle. The gauge-changeable wheel set comprises an axle, a pair of wheels, a pair of shaft sleeves, an outer sleeve and a linkage mechanism. A section of first non-self-locking thread is arranged in the inner periphery of each shaft sleeve, the rotating directions of the first non-self-locking threads are opposite, and the pair of wheels is fastened on the pair of shaft sleeves; two sections of second non-self-locking threads which form a non-self-locking thread pair with the first non-self-locking threads are arranged on the axle at intervals; the wheel is mounted on the axle through a shaft sleeve, and the first non-self-locking thread is matched with the second non-self-locking thread; the outer sleeve is rotatably connected outside the axle; the linkage mechanism is installed between the axle and the outer sleeve and used for locking or unlocking rotation of the outer sleeverelative to the axle, and when the linkage mechanism unlocks rotation of the outer sleeve relative to the axle and the wheels are in an unloading state, the pair of wheels is pushed to synchronously rotate to get close to or get away from each other so as to achieve gauge changing. Gauge changing is simple, and the track gauge changing reliability is high.

Description

technical field [0001] The invention relates to the technical field of gauge-changing rail vehicles, in particular to a gauge-changing wheel set and a rail vehicle. Background technique [0002] Cross-border passenger and freight transportation has grown rapidly in recent years. However, due to the different gauges of railways in various countries, it has caused serious obstacles to cross-border railway transportation. In order to solve the problem that the different gauges of railways in various countries hinder cross-border railway transportation, a train with variable gauge is proposed, that is, when the train travels to the railway of another country, the distance between the wheels on the axle is changed. The spacing is adapted to the gauge of other countries' railways. [0003] However, the existing gauge-changing wheelset has a complicated track-changing mechanism, cumbersome track-changing operation, and low reliability. Contents of the invention [0004] The pre...
