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

Embodiment Construction

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, and not to limit the present invention.

[0027] The mechanism of the present invention is suitable for an end-driven gauge changing bogie gauge changing device, and an end-driven gauge changing bogie gauge changing device consists of an axle box, an end driving mechanism, and wheel set locking The mechanism and the axle box end cover positioning and centering mechanism are assembled. The end drive mechanism is installed on the sleeve through the tapered roller bearing assembly. When the gauge is changed, the wheel and the axle sleeve can follow the end drive mechanism One-piece axial sliding on the axle to achieve the purpose of changing the gauge; the following embodiment is based on the existing gauge-changing bogie, and the structur...

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 [0001] The invention belongs to the technical field of bogie systems, relates to gauge conversion technology, and specifically relates to an end face driving mechanism of a gauge-changeable bogie. Background technique [0002] With the vigorous development of the Silk Road Economic Belt, my country has carried out larger, 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 become the most important road in Asia and Europe. One of the land trade channels in China, but the railways of different gauge specifications in different countries and regions have brought many restrictions on the development of international combined transport. [0003] For railways with different gauges, domestic and foreign efforts are devoted to the research of a gauge-changing bogie, which can adapt to railways with different gauges by changing the wheelsets of t...
