The invention relates to a draw bar trailer braking system and a draw bar trailer. The draw bar trailer braking system comprises: a gas storage container having a container gas inlet and a container gas outlet; a release valve which is provided with a release valve air inlet, a release valve air outlet and a release valve connector, the release valve air inlet is used for being communicated with a tractor air supply pipeline, and the release valve connector is communicated with the container air outlet; an emergency relay valve which is provided with a relay valve air outlet, a first relay valve air inlet, a second relay valve air inlet and a relay valve connector, the relay valve air outlet is used for being communicated with brake control valves of axles, the first relay valve air inlet is used for being communicated with a tractor control pipeline, and the relay valve connector is communicated with a container air inlet; and the second relay valve air inlet is communicated with the release valve air outlet. After the tractor air supply pipeline and the tractor control pipeline are separated or broken, the traction rod trailer can automatically generate emergency braking, and safety accidents caused by loss of braking capacity are avoided.

    本发明涉及一种牵引杆挂车制动系统及牵引杆挂车。牵引杆挂车制动系统,包括:储气容器,具有容器进气口和容器出气口;释放阀,具有释放阀进气口、释放阀出气口以及释放阀接口,释放阀进气口用于与牵引车供气管路连通,释放阀接口与容器出气口连通;紧急继动阀,具有继动阀出气口、第一继动阀进气口、第二继动阀进气口以及继动阀接口,继动阀出气口用于连通各车轴的制动控制阀,第一继动阀进气口用于连通牵引车控制管路,继动阀接口与容器进气口连通,第二继动阀进气口与释放阀出气口连通。在牵引车供气管路和牵引车控制管路脱开或断裂后,牵引杆挂车能够自动产生应急制动,避免失去制动能力导致安全事故的发生。
