A kind of variable gauge bogie end face drive mechanism

Abstract

The invention discloses an end surface driving mechanism for a gauge-changeable bogie. The end surface driving mechanism for the gauge-changeable bogie comprises a sliding sleeve, a driving sliding sleeve, locking arms, driving arms and driving roller assemblies; the driving sliding sleeve is mounted on the sliding sleeve through a bolt; two locking arm mounting threaded holes and driving arm mounting threaded holes are formed in the end surface of the driving sliding sleeve; the locking arms are mounted in the locking arm mounting threaded holes; the driving arms are mounted in the driving arm mounting threaded holes; the driving roller assemblies are mounted on the driving arms; and the driving roller assemblies roll on a ground assorted gauge-changeable driving rail to change the wheeltrack of a wheel pair. The end surface driving mechanism for the gauge-changeable bogie is suitable for an end surface driving type gauge-changeable bogie gauge changing device; and the problems thata wheel rim is seriously worn and non-uniformly stressed in the lateral direction during changing the gauge and a sliding shaft sleeve is easy to generate clamping stagnation or wear under an effect of a bending moment are solved.

Description

technical field The invention belongs to the technical field of bogie systems, and relates to gauge changing technology, in particular to a drive mechanism for a bogie end surface with variable gauge gauge. Background technique 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. 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 of the variable-gauge bogie....

AI Technical Summary

Problems solved by technology

At present, the wheelbase of the bogie wheelset is changed by applying a lateral force to the rim of the wheelset. Uniform and sliding bushings are prone to sticking or uneven wear due to the bending moment
