The invention discloses an urban rail vehicle frame control brake unit which comprises an electric connector, a common control unit, a weight-following valve, an electric air relay valve, a pressure reducing valve, a two-position three-way electromagnetic valve, a throttler and a plurality of pressure collecting and testing connectors. Six air passage ports are formed in the frame control brake unit and comprise a main air port, a standby brake load port, an air spring pressure port, a parking brake input port, a parking brake output port and a brake cylinder port; the main air port is connected with the common control unit through a cock, connected with the electric air relay valve and then connected with a third two-way valve through the pressure reducing valve and the two-position three-way electromagnetic valve. The frame control brake unit has the functions of service brake, emergency brake, standby brake load adjustment, emergency brake load adjustment, emergency load signal generation, parking brake superposition prevention and the like, in addition, the frame control brake unit adopts a mechanical fixed lever ratio weight-following valve structure for emergency brake, pureair brake is adopted, the response speed is high, and the safety is higher.

    本发明公开了一种城轨车辆架控制动单元,包括电连接器、常用控制单元、随重阀、电空中继阀、减压阀、两位三通电磁阀、节流器以及多个压力采集及测试接头;在所述架控制动单元上设置有六个气路口,包括总风口、备用制动载荷口、空气弹簧压力口、停放制动输入口、停放制动输出口以及制动缸口;所述总风口通过塞门与常用控制单元,所述总风口与电空中继阀连接,所述总风口经减压阀、两位三通电磁阀后,与第三双向阀连接。本发明同时具备常用制动、紧急制动、备用制动载荷调整、紧急制动载荷调整、应急载荷信号生成、停放制动防叠加等功能,此外,本架控制动单元紧急制动采用机械式定杠杆比随重阀结构,为纯空气制动,响应速度快,安全性更高。
