摘要
随着轨道车辆技术的不断发展,对转向架轻量化、低轮轨作用力等提出了更高的要求。国外多年的研究和试验表明,与轴箱外侧悬挂转向架相比,轴箱内置式转向架具有质量小、通过曲线能力强、轮轨磨耗小、噪声低等特点。我国对内置式转向架,尤其是轴箱内置式转向架的研究较少,在工程上的应用也尚属空白。介绍了国内外轴箱内置式转向架的技术研究和市场应用情况。介绍了中车长春轨道客车股份有限公司在对国内外典型的轴箱内置式转向架研究的基础上开发的200 km/h速度等级以上的轴箱内置式转向架的构架和主要技术参数。
With the continuous technological development of railway vehicles,higher requirements are put forward for bogie such as lightweight and low wheel-rail force.The research and tests abroad over the years have shown that compared with the out-board bogie,the in-board bogie has the features of small mass,strong curve passing capacity,low wheel-rail wear and low noise.Little research has been conducted on in-board bogie,especially that axle box in-board bogie in China and related engineering application is a blank field.The research and market application situation of axle box in-board bogie technology at home and abroad are introduced.With research background of the domestic and foreign typical in-board bogie,CRRC Changchun Railway Vehicles Co.Ltd.has developed the in-board high-speed bogie with speed level above 200 km/h,the structure and main parameters of which are introduced.
