The invention discloses a return rescue braking system for urban rail transit vehicles, which studies matching characteristics with functions and performance of a locomotive air brake and an interface relationship with an electrical system of a train, and can realize synchronous braking and relieving with the locomotive. Therefore, the braking synchronism during returning and rescue is ensured, and the longitudinal impulse of the train is reduced; the gas circuit design, the electrical design and the braking instruction conversion function of a certain type of urban rail transit vehicle under the working conditions of locomotive return and locomotive rescue are specifically researched, and the problems needing to be specially noticed in the design of matching the return rescue function with a train electrical interface and the like are proposed; when the system is integrated in a brake control unit, a train pipe penetrating through the whole train and an automatic brake system do not need to be arranged, and the equipment purchase cost is reduced; the purposes of improving the product integration level, improving the braking sensitivity, reducing the longitudinal impulse of the train, protecting bogie equipment and improving the braking effect of the train are achieved, and the application requirements for returning and rescuing of urban trains are met.
本发明公开了一种市域轨道交通车辆回送救援制动系统,本发明研究了与机车空气制动机功能、性能的匹配特性,以及与列车自身电气系统的接口关系,能够实现与机车的同步制动与缓解,以保证回送和救援时的制动同步性、减小列车纵向冲动;并具体研究了某型市域轨道交通车辆在机车回送、机车救援工况下的气路设计、电气设计和制动指令转换功能,并提出了回送救援功能与列车电气接口匹配等设计中需要特别注意的问题,本发明集成于制动控制单元中时无需设置贯穿全列的列车管和自动制动系统,降低了设备采购成本;实现了提高产品集成度、提高制动灵敏度、减少列车纵向冲动、保护转向架设备和提高列车制动效果的目标,满足市域列车回送、救援的运用要求。
