The invention relates to an axle control type brake control system and a rail transit vehicle, the axle control type brake control system comprises an electronic brake control unit and a pneumatic brake control unit, the pneumatic brake control unit comprises a main gas circuit, and an emergency brake adjusting module, a service brake and anti-skid adjusting module and a remote relieving module are arranged on the main gas circuit. The emergency braking adjusting module comprises a pressure reducing valve and a first electric proportional valve, the service braking and anti-skid adjusting module comprises a second electric proportional valve, and the remote relieving module comprises a first electromagnetic valve and a second electromagnetic valve. The air inlet end of the main air path is used for being connected with a main air pipeline, and the air outlet end of the main air path is used for being connected with a basic braking unit. Precise control over the braking force of the train can be achieved, the service life of each valve in the control system is longer, the number of parts is smaller, the size is smaller, the system is more simplified, the weight is lighter, the response time of braking control can be greatly prolonged, and train operation can be safer.
本发明为一种轴控式制动控制系统及轨道交通车辆,轴控式制动控制系统包括电子制动控制单元和气动制动控制单元,气动制动控制单元包括主气路,在主气路上设有紧急制动调节模块、常用制动及防滑调节模块和远程缓解模块。紧急制动调节模块包括减压阀和第一电气比例阀,常用制动及防滑调节模块包括第二电气比例阀,远程缓解模块包括第一电磁阀和第二电磁阀。主气路的进风端用于与总风管路连接,主气路的出风端用于与基础制动单元连接。本发明可实现车辆制动力的精准化控制,控制系统中的各阀寿命更长,部件数量更少,体积更小,系统更加简化,重量更轻,制动控制的响应时间将会有很大的提高,并可使列车运行更加安全。
