High speed train non-power wheel pair axle box device for standard-narrow gauge conversion

Abstract

The invention provides a high speed train non-power wheel pair axle box device for standard-narrow gauge conversion. A slip mechanism is mounted on a non-power axle; the slip mechanism is used for driving wheels to slip on the non-power axle during rail changing; a locking locating pin is arranged between the slip mechanism and an axle box rotating arm beam and used for locking and fixing the slipmechanism before and after gauge changing; a bearing seat is mounted at the bottom of the axle box rotating arm beam and used for bearing a train during slipping; and axle locating mechanisms are arranged at two ends of the non-power axle are used for realizing the axle locating of the axle. According to the high speed train non-power wheel pair axle box device for the standard-narrow gauge conversion, the distance between backs of the wheel pairs is variable through the slipping of the slip mechanism on the non-power axle so as to realize the standard-narrow gauge conversion; therefore, problems that the prior art cannot adapt to gauge change and needs to change the bogie because the distance between backs of the wheel pairs in the prior art is fixed are solved.

Description

technical field [0001] The invention relates to a wheel-to-axle box device for a high-speed train set, in particular to a non-powered wheel-to-axle box device for a high-speed train set that can realize quasi-narrow gauge conversion. Background technique [0002] Due to the different railway gauges adopted by countries around the world, in the process of cross-border transport, when domestic passenger and freight railway vehicles run from 1435mm gauge lines to 1000mm gauge lines, it is necessary to replace the bogies that meet the requirements of different gauges. [0003] In the traditional bogie non-powered wheel-to-axle box device, the wheels are installed on the axle through interference fit, and the two are relatively fixed, so the inner distance of the wheel set remains unchanged, which can only meet the operation requirements of one gauge. When passing lines with different gauges, it is necessary to stop and go back to the warehouse to replace the bogie that adapts to...

Problems solved by technology

[0004] In order to solve the problem that the inner distance of the traditional bogie wheel set is fixed and the conversion function of quasi-narrow gauge cannot be realized, reduce the manpower and material costs caused by bogie replacement during cross-border transport, and improve operational efficiency, the present invention provides a quasi-narrow gauge conversion function. The non-powered wheel-to-axle box device for high-speed EMUs with narrow gauge conversion enables high-speed EMUs to pass directly without changing the bogies when running from a 1435mm gauge line to a 1000mm gauge line
