End face drive centering and locking integrated gauge changeable bogie gauge conversion device

Abstract

The invention discloses an end face drive centering and locking integrated gauge changeable bogie gauge conversion device. The device comprises an axle box, an end face drive mechanism, a wheel set locking mechanism and an axle box end cover locating centering mechanism. The device is applied to a gauge changeable bogie, wherein wheels and axle sleeve of the bogie are arranged integrally and can slide integrally along an axle direction, and an axle and axle sleeve of the bogie in splined connection, the end face drive mechanism is arranged on the axle sleeve through a tapered roller bearing assembly, when the gauge is converted, the vehicle wheels and the axle sleeve can slide integrally along with an end face drive device along the axial direction of the axle to achieve the conversion ofthe gauge; the wheel set locking mechanism can lock the end face drive device under a certain gauge, thereby preventing the vehicle wheels and the axle sleeve from moving along the axial direction ofthe axle, the axial locking of the end face drive mechanism can be removed along the axial direction of the axle when the gauge is changed, and it is ensured that the vehicle wheels and the axle sleeve slide along the axial direction of the axle when the gauge is changed; and the axle box end cover locating centering mechanism is used for the locating centering of the axial direction of the axle when the gauge is changed.

Description

technical field [0001] The invention belongs to the technical field of bogie systems, and relates to gauge changing technology, in particular to a track gauge changing device of an end-face driving, centering and locking integrated variable-gauge bogie. 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 ...

AI Technical Summary

Problems solved by technology

At present, the track change of the bogie wheel set is achieved by applying a lateral thrust to the rim of the wheel set. This method not only causes wear on the rim of the wheel set, but also causes The lateral force is uneven, and the sliding bush is prone to sticking or uneven wear under the action of bending moment
