Axle assembly applied to variable-gauge bogie

Abstract

The invention belongs to the technical field of bogie systems and particularly relates to an axle assembly applied to a variable-gauge bogie. The axle assembly comprises an axle and a bearing and wheel integrated mounting seat. The positions of a wheel seat of the axle to the ends are moving pair connection parts. The bearing and wheel integrated mounting seat comprises bearing mounting seats andwheel mounting seats which are mutually connected and further comprises moving pair joint parts. The moving pair joint parts and the moving pair connection parts form axial moving pairs. The purposesof the axle assembly are that aiming at the problem that when a train passes through railways with different gauges, the transport efficiency is low, the axle assembly is provided and applied to the bogie, so that wheels can be adjusted in the axial direction relative to the axle, and thus the wheel distance of a wheel set of the bogie is converted to adapt to the railways with the different gauges. Railway transportation of 'Silk Road Economic Belt' is developed, thus the problem that the railway gauges are not uniform is faced, and therefore, quite important and profound significance is achieved on development of design of a variable-gauge bogie system.

Description

technical field [0001] The invention belongs to the technical field of bogie systems, and in particular relates to an axle assembly applied to a variable-gauge bogie. Background technique [0002] 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 are two options to choose from. One is the method of transshipment of cargo boxes, that is, hoisting the cargo boxes from a train with one gauge specification to a train with another gauge specification; The bogie of one gauge specification is removed, and the bogie of another gauge specification is installed. The inefficiency of these two modes of transportation has brought many restrictions to the development of international intermodal transport.

Problems solved by technology

[0004] The object of the present invention is to provide an axle assembly applied to a variable-gauge bogie for the problem of low transportation efficiency when trains pass through railways with different gauges. The axle assembly is applied to the bogie so that the wheels are relatively Because the axle can be adjusted in the axial direction, so as to realize the transformation of the wheel set track of the bogie to adapt to the railway of different gauges
