Problems solved by technology

[0004] The object of the present invention is to provide a method for changing the gauge for the problem of low transport efficiency when trains pass through railways with different gauges. Based on this method, the wheels of the bogie can be adjusted axially relative to the axle, thereby Realize the transformation of the wheel set and track of the bogie to suit railways with different gauges

Embodiment 1

[0034] A gauge change method, comprising the following steps: step i. supporting the bogie to unload the wheels; step ii. unlocking the sliding parts to free the wheels; step iii. sliding the wheels to change the track.

[0035] The bogie is supported in the step i by means of axle box support. The support of the axle box is realized by the support rail installed on the ballast bed, and the support rail is arranged below the axle box.

[0036] In the step ii, the wheel is dissociated in such a way that the bearing mounting seat and the wheel mounting seat are integrally arranged to form an integrated bearing and wheel mounting seat, and the integrated bearing and wheel mounting seat is separately arranged from the axle, and the two can slide relative to each other in the axial direction. In the step ii, the wheel is in a locked state before unlocking. The locking method is to set a sliding piece between the axle box and the bearing, and set a locking piece between the sliding ...

Abstract

The invention belongs to the technical field of bogie systems and particularly relates to a gauge transformation method. The gauge transformation method comprises the following steps that (i) a bogieis supported, so that wheels are unloaded; (ii) sliding pieces are unlocked, so that the wheels are separated; and (iii) the wheels are slid to change rails. The purposes of the gauge transformation method are that aiming at the problem that when a train passes through railways with different gauges, the transport efficiency is low, the gauge transformation method is provided, based on the method,the wheels of the bogie can be adjusted in the axial direction relative to an axle, and thus the wheel distance of a wheel set of the bogie is transformed to adapt to the railways with the differentgauges. Railway transportation of 'Silk Road Economic Belt' is developed, thus the problem that the railway gauges are not uniform is faced, the situation that the variable-gauge bogie is provided forthe train is the most economical and efficient way to solve the problem of non-uniform railway gauge specifications, and therefore, quite important and profound significance is achieved on development of design of a variable-gauge bogie system.

Description

technical field [0001] The invention belongs to the technical field of bogie systems, and in particular relates to a gauge changing method. Background technique [0002] With the proposal of the "Belt and Road" strategic concept, the business exchanges between my country and neighboring countries through railway transportation have become increasingly frequent, and a number of international railway transport and regional transport channels have been developed between my country and neighboring countries. The "Silk Road Economic Belt", as one of the most important land trade routes connecting the Eurasian continent, has made the Eurasian Continental Bridge an important railway transportation link, bringing benefits to the people's economy along the road. However, due to historical reasons, railways in different countries and regions have adopted different gauge specifications. [0003] At present, when trains pass through railways with different gauge specifications, there a...
