A Gauge Changing Device of a Gauge Changing Bogie Driven by an End Face

Abstract

The invention discloses an end surface driving type gauge-changeable bogie gauge changing device. The end surface driving type gauge-changeable bogie gauge changing device comprises an axle box, an end surface driving mechanism, a wheel pair locking mechanism and an axle box end cover positioning and centering mechanism; the end surface driving mechanism is mounted on an axle sleeve through a tapered roller bearing assembly; when the gauge is changed, a wheel and the axle sleeve can slide together with the end surface driving mechanism in the axial direction of an axle so as to realize the gauge changing; the wheel pair locking mechanism can lock the end surface driving mechanism at one gauge so as to prevent the wheel and the axle sleeve from jumping in the axial direction of the axle andcan also release the locking of the end surface driving mechanism in the axial direction of the axle during the changing of the gauge so as to guarantee that the wheel and the axle sleeve axially slide together along the axle during the changing of the gauge; and the axle box end cover positioning and centering mechanism is used for axial positioning and centering of the axle during the changingof the gauge. According to the end surface driving type gauge-changeable bogie gauge changing device, the problems that the wheel flange wear is serious, the lateral force is uneven and the sliding axle sleeve is easy to generate clamping stagnation or uneven wear under an effect of a bending moment are solved.

Description

technical field [0001] The invention belongs to the technical field of bogie systems, and relates to gauge changing technology, in particular to an end-face-driven track gauge changing device for variable-gauge bogies. Background technique [0002] With the vigorous development of the Silk Road Economic Belt, my country has carried out larger-scale, higher-level, and deeper regional cooperation with countries along the route, and is committed to building an all-round interconnection network. Among them, railway transportation has increasingly become the most important part of the Eurasian road. However, railways with different gauge specifications in different countries and regions have brought many restrictions to the development of international intermodal transport. [0003] Aiming at railways with different gauges, domestic and foreign are committed to researching a variable-gauge bogie, which can adapt to railways with different gauges by changing the wheel set wheelbase...

AI Technical Summary

Problems solved by technology

At present, the change of the wheelbase of the bogie wheel is realized by applying a lateral force to the wheel rim of the wheel set. all

Aiming at the problems of severe wheel rim friction and uneven lateral force of the existing variable-gauge bogie, an end-drive type variable-gauge bogie gauge changing device is proposed
