变轨距转向架的应用发展及现状

Development and present situation of gauge-changeable bogie

随着经济的快速发展,我国和世界各国之间的物资运输日益增多。由于我国和其他周边国家轨距的不同,为国际联运和"一带一路"的建设带来了巨大的障碍,因此对变轨距转向架的需求日益增大。文章对变轨距转向架的变轨机构和变轨技术进行了研究和分析,阐述了变轨距转向架的应用及发展情况,并结合国内外变轨距转向架的应用情况,介绍了几种变轨距转向架,并对其关键技术进行了介绍分析,论述了变轨距转向架在"一带一路"背景下的研究意义和价值。

With the rapid development of economy, the transportation of goods between China and the world is increasing day by day. Because China and other neighboring countries have different gauges, which cause huge obstacles for intemational transport and ＂the Belt and Road＂ construction, there is a growing demand for gauge- changeable bogie. With analysis and research of rail gauge changing technology and gauge changing mechanism, the development and current status of gauge-changeable bogie are described. Combined with the operation of foreign gauge-changeable bogie, several key technologies of gauge-changeable bogie are introduced. Under the background of ＂the Belt and Road＂, the significance and value of gauge-changeable bogie is discussed.
