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 field of train variable gauges, discloses a locking mechanism for a variable gauge wheel set and the variable gauge wheel set. The variable gauge wheel set comprises a bearing sleeve and a locking rod, wherein the inner circumference of the bearing sleeve is provided with an annular positioning boss dividing the inner circumferential surface of the bearing sleeve intoa locking working surface and a press-fit working surface. The two opposite sides in the radial direction of the locking working surface are respectively provided with a set of gauge change grooves, each set of gauge change grooves comprises a plurality of gauge change grooves formed at the axial interval, and through notches are formed in the locking working surface below the two sets of gauge change grooves. The locking rod comprises two symmetrical locking pins and unlocking rods hinged to the two locking pins. The two locking pins are respectively inserted into a single gauge change grooveof the corresponding group to achieve locking, the unlocking rods extend out of the bearing sleeve from the notches and enable the locking pins to be separated from the current gauge change grooves under the external force to achieve unlocking. The locking mechanism can achieve the locking and the unlocking reliably to meet the variable gauge requirement of a train.

Description

technical field [0001] The invention relates to the technical field of gauge-changing rail vehicles, in particular to a locking mechanism for a gauge-changing wheel set and a gauge-changing wheel set. 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...
