The invention discloses a multifunctional self-walking trailer braking system, relates to the technical field of trailers, and solves the technical problem that braking of a multifunctional trailer cannot be met in the prior art. Comprising a first air source interface group, a second air source interface group, a first emergency relay valve, a first relay valve, a service braking electromagnetic valve, a second emergency relay valve, a three-way ball valve, a five-port two-position electromagnetic valve, a pneumatic control reversing valve, four double-cavity braking air chambers, four second relay valves, a quick release valve, a four-protection valve and four air storage devices. The system has a train working mode, a self-walking working mode with the tractor in the front and a self-walking working mode with the tractor in the rear, the braking problem of the self-walking trailer is solved in a one-stop mode, and the risk of brake failure caused by air leakage of the trailer is effectively reduced through a four-protection valve; by means of the emergency relay valve, major safety accidents caused by the fact that an air channel between the tractor and the trailer is disengaged or broken can be avoided.

    本发明公开一种多功能自行走挂车制动系统,涉及挂车技术领域,解决了相关技术中无法满足多功能挂车的制动的技术问题。包括第一气源接口组、第二气源接口组、第一紧急继动阀、第一继动阀、行车制动电磁阀、第二紧急继动阀、三通球阀、五口二位电磁阀、气控换向阀、四个双腔制动气室、四个第二继动阀、快放阀、四保阀和四个储气装置。本系统具有列车工作模式、牵引车在前的自行走工作模式和牵引车在后的自行走工作模式,一站式解决自行走挂车的制动难题,通过四保阀有效降低车辆因漏气而导致刹车失灵的风险,通过紧急继动阀可避免因牵引车与挂车之间的气路脱开或断裂后所产生的重大安全事故。
