Abstract

The invention relates to the technical field of changeable gauge of railway vehicles, and discloses a sealing structure for gauge-changeable wheelsets. The sealing structure comprises an outer ring, an inner ring and an elastic sleeve, wherein the inner diameter of the outer ring is larger than the outer diameter of the inner ring. One end of the elastic sleeve is fixedly connected with the innercircumference of the outer ring, the other end of the elastic sleeve is fixedly connected with the outer circumference of the inner ring, and the outer ring can drive the elastic sleeve to move relative to the inner ring together. The sealing structure for the gauge-changeable wheelsets has a simple and compact structure, and wheels and axles can be well sealed when gauge is changed.

Description

technical field [0001] The invention relates to the technical field of gauge change for rail vehicles, in particular to a sealing structure for a gauge change wheel set. Background technique [0002] In order to meet the transportation requirements between tracks of different gauges in neighboring countries, bogies with different inner distances of wheel sets are often replaced at the junction. This solution is costly and time-consuming. Spain and Japan successively invented variable-gauge bogies, which can run continuously between tracks of different gauges. [0003] Since the wheels and axles need to slide relative to each other when the gauge is changed, the lubricating medium needs to be encapsulated and the lubricating interface should be kept clean, so it is urgent to design a sealing structure here. Contents of the invention [0004] (1) Technical problems to be solved [0005] The present invention aims to solve at least one of the technical problems existing in ...
