摘要:
变轨距转向架轮对与常规转向架轮对结构相比,需要增设一套用于轨距变化的解锁- 锁紧装置,其作用是实现车轮滑移前的解锁和运行中的锁紧固定,是直接影响能否顺利实现轮对内侧距变化和确保列车运行安全的关键部件。介绍了高速变轨距动车组转向架解锁- 锁紧装置的结构及作用原理,分析了该装置工作时的受力状态,同时对该装置进行了强度分析和寿命计算。分析和计算结果表明:解锁- 锁紧装置满足设计要求。
Abstract:
Compared with the traditional bogie wheelset structure, the gauge-changeable bogie wheelset needs a set of unlockinglocking device for track gauge change. The effect of the device is to realize the unlocking before the wheel slip and the locking during operation. It is a key component that directly influences the change of the inner distance of the wheelset and ensures the safety of the train. The structure and action principle of the unlocking-locking device of the bogie with high-speed gauge-changeable EMUs was introduced, and the force state of the device during operation was analyzed. At the same time, the strength analysis and life calculation of the device were performed. Analysis and calculation results showed that the unlocking-locking device met the design requirements.
