The invention discloses an active ventilation system for a railway vehicle, and relates to the technical field of railway vehicle braking systems. The active ventilation system for the railway vehicle comprises an air supply control module, an electromagnetic valve module and a ventilation module, the air supply control module is communicated with the electromagnetic valve module through a pipeline, and the electromagnetic valve module is communicated with the ventilation module through a pipeline; the air supply control module comprises a first air supply pipeline, a second air supply pipeline and a third air supply pipeline, and the first air supply pipeline communicates with the second air supply pipeline and the third air supply pipeline. According to the invention, the problem that a long ramp exists due to the influence of terrains in the construction process of an urban rail transit line is solved, so that the problem that the temperature of a brake shoe and a wheel pair tread is too high and the tread is damaged due to frequent application of a braking system in the running process of a vehicle is solved.
本发明公开了轨道车辆用主动式通风系统,涉及轨道车辆制动系统技术领域。其中,该轨道车辆用主动式通风系统,包括:供风控制模块、电磁阀模块和通风模块,所述供风控制模块通过管路与所述电磁阀模块相连通,所述电磁阀模块通过管路与通风模块相连通;所述供风控制模块包括:第一供风管路、第二供风管路和第三供风管路,所述第一供风管路分别与所述第二供风管路和所述第三供风管路相连通。本发明,解决城市轨道交通线路在建设过程中,由于受到地形的影响,会存在长大坡道的问题,因此,在车辆运行过程中,制动系统会频繁施加,从而会造成闸瓦和轮对踏面温度过高,对踏面造成损伤的问题。
