Unlocking part applied to variable-gauge bogie

Abstract

The invention belongs to the technical field of bogie systems and particularly relates to an unlocking part applied to a variable-gauge bogie. The unlocking part comprises a V-shaped base frame, and two ends of the base frame are connected with the lower ends of locking parts respectively. Aiming at the problem of low transport efficiency when a train passes railways in different gauges, the unlocking part is provided and applied to the bogie to enable unlocking of a wheel adjusted and locked axially relative to an axle, and accordingly wheel set gauge of the bogie can vary to adapt to the railways in different gauges. Facing the problem of railway gauge nonuniformity is inevitable in development of 'Silk Road economic belt' railway transport, while providing the train with the variable-gauge bogie is a most economical and effective method for solving the problem of railway gauge nonuniformity, and therefore, developing variable-gauge bogie system design has quite important and profound significance.

Description

technical field [0001] The invention belongs to the technical field of bogie systems, and in particular relates to an unlocking part applied to a variable-gauge bogie. 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 g...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide an unlocking part applied to a variable gauge bogie for the problem of low transportation efficiency when trains pass through railways with different gauges, and the unlocking part is applied to the bogie to make the wheels relatively After the axle is adjusted in the axial direction and locked, it can be unlocked, so as to realize the change of the wheel set wheel gauge of the bogie to adapt to railways with different gauges

The locking rod of the locking part works alone, which is prone to the problem of asynchronous movement
