Abstract

The invention belongs to the technical field of bogie systems, and particularly relates to a variable gauge bogie. The variable gauge bogie comprises an axle assembly, a sliding key assembly and an axle box assembly. The axle assembly comprises an axle and a bearing and wheel integrated mounting seat. The sliding key assembly comprises a sliding part. The axle box assembly comprises an axle box and a bearing. The position from a wheel seat to the end part of the axle is provided with a moving pair connecting part. The bearing and wheel integrated mounting seat comprises a bearing mounting seat and a wheel mounting seat which are mutually connected and further comprises a moving pair junction part. The moving pair junction part and the moving pair connecting part form an axial moving pair. The sliding part is of a cylindrical body. The outer side wall of the cylindrical body is in axial slidable connection with the axle box. The inner side wall of the cylindrical body is in axial fixed connection with the bearing mounting seat through the bearing. The wheel axial direction of the variable gauge bogie is adjustable to be adapted to different gauges, railway transportation of ''Silk Road Economic Belt'' is developed, and the problem that railway gauges are not uniform must be solved, therefore, it is very important and far-reaching to carry out design of the variable gauge bogie.

Description

technical field [0001] The invention belongs to the technical field of bogie systems, and in particular relates 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 gauge specifications, there ar...
