近十年来,在铁道车辆转向架技术的发展中出现了一股新的潮流,许多国家的铁路和铁路工业部门竞相研制径向转向架,取得了较大的进展,引起了世界范围内的广泛注意。径向转向架的设计思想,不同于传统三大件和H形构架转向架,它具有许多独特的优越性。这主要是克服了蛇行稳定性与曲线通过能力的矛盾,能够在保证足够的直线运行稳定性的同时减少轮缘、踏面和钢轨的磨耗,减少机车的燃料消耗,特别适应于在多曲线小半径线路上高速重载车辆的运用要求,具有很大的技术经济意义。
In recent ten years, there has been a new trend in the development of railway vehicle bogie technology. In many countries, the railway and railway industry departments have been racing to develop radial bogies. Great progress has been made and a worldwide note. Radial bogie design idea, different from the traditional three-piece and H-shaped bogie, it has many unique advantages. This mainly overcomes the conflict between the meandering stability and the curve passing ability, and can reduce the wear of the rim, the tread and the rail while reducing the locomotive fuel consumption while ensuring sufficient linear stability. In particular, The requirements for the application of high-speed heavy-haul vehicles on lines are of great technological and economic significance.
