摘　　要：在小半径曲线较多的线路上,使用径向转向架有利于减少轮轨磨耗、降低铁路机车的运营维护成本。文章基于HX_(D)1C型机车三轴径向转向架技术,通过在HX_(D)1型机车转向架的底部加装一套下置式径向装置,研发了一种两轴径向转向架,并对构架、一系悬挂装置等进行了适应性修改。该转向架的整体方案与径向装置高度利用了HX_(D)1C型机车径向转向架的研究成果,将三轴径向转向架技术移植到两轴径向转向架,实现了平台化、系列化、简统化的目的,并对原有径向装置的潜在问题进行了改进。On the line with many small radius curves,the use of radial bogie is beneficial to reduce the wear of wheels and rails,and reduce the operation and maintenance cost of railway locomotive.Based on the technology of HX_(D)1C locomotive three-axle radial bogie,a two-axle radial bogie is developed by installing a set of lower placement type radial device at the bottom of HX_(D)1C locomotive bogie,and the frame and primary suspension device are modified adaptively.The overall scheme and radial device of the bogie highly use the research results of HX_(D)1C locomotive radial bogie,transplant the three-axle radial bogie technology into the two-axle radial bogie,achieve the purpose of platform,serialization and simplification,and improve the potential problems of the original radial device.
