Description

Technical Field

[0001] The utility model relates to the technical field of track gauge change of rail vehicles, in particular to a bogie for wheel pair track gauge change. Background Art

[0002] The main mode of trade and transportation between my country and other countries in the economic zone relies on the railway transportation of the Eurasian Continental Bridge. Since its opening, the China-Europe Express has continued to expand its operation volume, and the cargo transportation volume has repeatedly reached new highs, basically achieving full coverage of the main cargo sources in Central Asia, South Asia, West Asia and Europe. However, due to the different track gauges of railways in various countries, the China-Europe Express must change tracks during cross-border transportation, which not only increases costs, but also affects transportation efficiency, greatly hindering the development of railway transportation. After searching: Patent No. CN108909762B is a wheelset and bogie for a railway vehicle gauge-changing bogie, which includes a wheel, an axle and a locking assembly; the wheel hub is located on the outside of the wheel and a connecting sleeve is extended, the inner periphery of the wheel hub and / or the inner periphery of the connecting sleeve are provided with internal splines, and the two ends of the axle are respectively provided with external splines matching the internal splines, and the wheel and the axle are connected through the internal splines and external splines; the locking assemblies are respectively pressed on the outer periphery of the connecting sleeve of the wheel and are located in the axle box at both ends of the axle, and the locking assembly is used to drive the wheel to move or lock along the axial direction of the axle box to achieve wheel gauge change.

[0003] However, the above-mentioned bogie for wheelset track change still has some shortcomings. The spring and the rod body are set to lock the adjusted connecting sleeve and the wheel. Due to the elasticity of the spring, the rod body is easy to shake and disengage from the inner ring groove, and thus the connecting sleeve and the wheel cannot be locked stably, affecting the normal rotation of the wheel. When unlocking to adjust the wheelbase, due to the rebound force of the spring, the personnel need to hold it by hand all the time, affecting the convenience of operation. Therefore, we propose a bogie for wheelset track change to solve the above problems. Utility Model Content
