摘　　要：为解决低地板有轨电车在雨雪、结冰天气运行中可能造成液压制动单元油箱通气装置堵塞的问题,对现有的油箱通气装置进行了结构优化设计。基于目前用到的液压制动单元油箱通气装置,改进了通气装置结构,且设计了一种新的通气塞组成。优化装置可以通过通气管路结构和通气塞组成双重防护来保障油箱与外界大气的畅通性。To solve the blockage issue with the fuel tank ventilation device of the hydraulic brake unit when low-floor trams run in rain,snow and icy weather,a structural optimization design was conducted for the existing fuel tank ventilation device.The structure of the current fuel tank ventilation device is improved,and a new vent plug is designed.The optimized device ensures smooth flow between the fuel tank and the outside atmosphere through double protection of the ventilation pipeline structure and the vent plug.
