Problems solved by technology

However, in the existing variable-gauge train structure, the locking mechanism is complex in structure, cumbersome to operate, poor in reliability, and often cannot be locked and unlocked normally, which has become a restrictive factor hindering the development of variable-gauge trains

Abstract

The invention relates to the technical field of rail vehicle gauge change, and discloses a locking mechanism for a gauge change wheel set, which includes an outer sleeve and a locking pin; The boss axially extending along the outer sleeve is provided with a plurality of grooves at intervals along the length direction of the boss, and the locking pin is used to be inserted into the grooves, and can be locked under the action of an external force. Switching between multiple grooves is used for changing gauge. The locking mechanism of the present invention is simple in structure, easy to operate, and can reliably realize locking and unlocking, thereby conveniently and reliably realizing train gauge change, and solving the problem of continuous running of trains on tracks with different gauges.

Description

technical field [0001] The invention relates to the technical field of gauge change of rail vehicles, in particular to a locking mechanism for a wheel set of gauge change. Background technique [0002] With the rapid development of global economic integration, cross-border passenger and cargo 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 variable-gauge bogie is proposed, that is, when the train travels on the railways of other countries, by changing the wheels on its own wheelset The distance between them is adapted to the gauge of other countries' railways. [0003] In the process of changing the gauge of the train, relative motion will occur between the wheels on the same wheel set, and the lock...
