Abstract

The invention discloses a variable gauge bogie wheel pair orbital transfer performance and reliability test stand. The test stand mainly comprises a motor, a motor support, a first coupling, a double-output shaft reducer, a concave base, a second coupling, a first bearing, a first bearing support, a second bearing, a second bearing support, a first gauge adjustment roller assembly, a second gaugeadjustment roller assembly, a variable gauge wheel pair, a gantry wheel pair fixing device and a pedestal, wherein the first gauge adjustment roller assembly or the second gauge adjustment roller assembly comprises a left guide rail, a right guide rail, a roller, a roller shaft, an adjustment pad and a locking nut, and the gantry wheel pair fixing device comprises a column, a supporting platform and a wheel pair fixing supporting block. The test stand is advantaged in that the structure is simple, the orbital transfer action of the variable gauge wheel pair can be simulated in a cycle mode, and a problem of difficulty in testing variable gauge performance and reliability of the wheel pair existing in a variable gauge train in the actual running process in the prior art is solved.

Description

Technical field [0001] The invention relates to the field of dynamic simulation and testing of rail vehicles, in particular to a rail-change performance and reliability test bench of a gauge-changeable bogie wheelset. Background technique [0002] With the vigorous development of the Silk Road Economic Belt, China has carried out larger, higher-level and deeper regional cooperation with countries along the route, and is committed to building an all-round interconnection network. Among them, railway transportation has become the most important road in Asia and Europe. However, the railways of different gauge specifications in different countries and regions have brought many restrictions on the development of international intermodal transportation. In order to solve the problems of international intermodal transportation caused by different railway gauges, the use of variable gauge bogies can Effectively solve the through operation of different gauges, which is time-saving and co...
