摘　　要：为解决不同轨距铁路区间直通运行问题,文章设计了一种适应1000 mm到1435 mm轨距变化的机车变轨距转向架及其轮对,通过对不同锁紧解锁方式的分析,选定了车轮锁紧式方案,并在此基础上确立了转向架总体方案和主要技术参数。文章重点分析了轮对及轨距变换过程,包括锁紧解锁机构内部结构、锁紧与解锁原理,以及销轴弹簧和轴向定位弹簧的设计。通过运动仿真分析,确立了销轴和楔形滑动块的摩擦因数。按照进入、解锁、变轨、锁紧和退出5个阶段描述了变轨过程,同时阐述了与变轨距轮对配合的地面变轨设施原理。文章提出的新型变轨距机车转向架方案及轮对的锁紧解锁原理和变轨过程,可作为后续开展变轨距机车转向架深入研究和工程化应用的参考。To facilitate through operation on railway lines with different gauges,this paper presents the design of a gauge-changeable locomotive bogie along with wheelsets that are adaptable to gauge changes between 1000 mm and 1435 mm.Based on a wheellocking mode that was selected after analyzing various locking and unlocking methods,the overall bogie solution and main technical parameters were established.The design focused on the wheelsets and the gauge-changing process,including the internal structure of the locking and unlocking device,the principles of locking and unlocking,and the design of the pin spring and axial positioning spring.Subsequent motion simulation analysis identified the friction coefficient between the pin and the wedge sliding block.The gauge-changing process was described in five stages:entry,unlocking,gauge changing,locking,and exit.Meanwhile,the principle of a ground transformation facility working in conjunction with the gauge-changeable wheelsets was explained.The new gauge-changeable locomotive bogie solution,alongside the locking-unlocking principle of the wheelsets and gauge-changing process proposed in this paper serve as a reference for further research and engineering application of gauge-changeable locomotive bogies.
