Abstract

The invention relates to the field of variable gauges of railway vehicles, and provides an axle for a variable-gauge wheel set and the variable-gauge wheel set. The axle for the gauge-changeable wheelset comprises an axle body. A central through hole is formed in the axial direction of the axle; an outer spline extending in the axial direction of the axle is arranged in the periphery, close to the middle, of the axle. First non-self-locking threads opposite in rotating direction are arranged on the portions, located at the two sides of the axial direction of the outer spline, of the peripheryof the axle respectively, a long circular hole penetrating in the radial direction of the axle is formed in the portion, located on the outer spline, of the axle, and the length direction of the longcircular hole is in the axial direction of the axle. At least one first roller path arranged around the axle in the circumferential direction is formed in the portion, located between one of the first non-self-locking threads and the outer spline, of the axle. According to the invention, the axle is ingenious in structural design, the connecting structure of the axle and the wheels is simple, andgauge-changeable reliability is high.

Description

technical field [0001] The invention relates to the technical field of gauge change of rail vehicles, in particular to an axle for a gauge change wheel set and a gauge change wheel set. 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 axle and wheel connection structure is complicated, and the reliability of gauge change is low. Contents of the invention [0004] The present inve...
