货车径向转向架原理及其运用

Development and Principle of Truck Radial Bogies

解决转向架曲线通过性能和横向稳定性之间的矛盾一直是车辆系统动力学长期研究的课题,采用常规转向架无法同时满足二者的要求。径向转向架的出现有效地解决了这一矛盾,其既能保证转向架曲线通过性能的要求,又能改善横向稳定性。简要介绍了国内外货车径向转向架的发展及其应用概况,并阐述了迫导向、自导向径向转向架的导向机理及其基本结构。对我国货车径向转向架的发展提出了建议。

Solving the conflict between curving performance and transverse stability is always a hard work in the fields of vehicle system dynamics in a long time. Using the conventional bogies can not meet the both requests at same time. The radial bogie, which not only meets the request of curving performance but also improves the hunting stability effectively, can solve the conflict. The application and development of radial bogies are introduced briefly, and the principles and structures of radial bogies are expounded. Suggestions are given for the development of radial bogies in our country.
