The invention discloses an ATP speed measuring shaft brake linkage cutting system for a railway vehicle, and relates to a high-speed motor train unit braking system. The problem that in the application process of an existing ATP system, the safe braking distance cannot be guaranteed is solved. When the vehicle is in a parking state, a two-position four-way electromagnetic valve is in a power-off state, and an ATP speed measuring shaft braking cylinder air supply pipeline is in a conducting state, the air brake of an ATP speed measuring shaft is normally applied, and the corresponding UB safetyloop is in a disconnected state at the moment; when a train is started normally, the UB safety loop is in a closed state, a signal corresponding to the UB safety loop linkage control circuit is in anelectrified state, the two-position four-way electromagnetic valve is electrified, a port A2 is communicated with a port A3, a main air source enters the two-position four-way pneumatic valve throughthe port A3, the port A2 of the two-position four-way pneumatic valve is communicated with the port A3, a port A1 is blocked, the brake pressure output by the relay valve cannot reach a brake cylinder, and at the moment, the ATP speed measuring shaft air brake linkage cutting system keeps the cutting state of ATP speed measuring shaft air brake.

    轨道车辆用ATP测速轴制动联动切除系统,涉及高速动车组制动系统,解决现有ATP系统在应用过程中,无法保证安全的制动距离等问题,当车辆处于停放状态时,所述二位四通电磁阀处于无电状态,ATP测速轴制动缸供风管路处于导通状态,ATP测速轴的空气制动正常施加,此时对应的UB安全环路为断开状态;当列车正常启动,所述UB安全环路处于闭合状态,对应UB安全环路联动控制电路的信号为有电状态,二位四通电磁阀得电,A2端口与A3端口导通,总风源经A3端口进入到二位四通气动阀内,二位四通气动阀A2端口与A3端口导通,A1端口被阻断,则中继阀输出的制动压力无法到达制动缸内,此时ATP测速轴空气制动联动切除系统保持ATP测速轴空气制动的切除状态。
