Locking piece applied to bogie with variable gauges

Abstract

The invention belongs to the technical field of bogie systems and particularly relates to a locking piece applied to a bogie with variable gauges. The locking piece comprises a lock rod and a lock block, wherein the lock block is positioned in an axle box and is connected to the upper part of the lock rod; and the lock rod is in slip connection with the axle box, and the lower part of the lock rodextends from the axle box to the outside of the axle box. Aiming at the problem of low transport efficiency when a train passes through railways with different gauges, the invention provides the locking piece, the locking piece is applied to the bogie, and wheels are adjusted relative to an axle in an axial direction and then can be locked, so that the wheel gauge between two wheels of the bogiecan be transformed so as to adapt to railways with different gauges. The railway transport developing the silk road economic belt has the problem of non-uniform railway gauges, and the most economic and effective method for solving the problem of non-uniform railway gauge specifications is to equip the bogie with variable gauges for the train, so that the development of design for the bogie systems with variable gauges has very important and profound significance.

Description

technical field [0001] The invention belongs to the technical field of bogie systems, and in particular relates to a locking piece 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 gau...

Problems solved by technology

[0004] The purpose of the present invention is to provide a locking piece applied to a variable gauge bogie for the problem of low transport efficiency when trains pass through railways with different gauges, and to apply the locking piece to the bogie so that The wheels can be locked after being adjusted in the axial direction relative to the axle, so that the wheel-to-wheel gauge of the bogie can be changed to adapt to railways with different gauges
