The invention relates to the technical field of trailer braking, and provides a trailer control valve and a trailer braking system. The trailer control valve comprises a control port, a relay valve, an air inlet and a first air outlet, the control port is connected with a control cavity of the relay valve, and the air inlet and the first air outlet are respectively connected with a brake cavity of the relay valve; the traction force control valve is arranged in a pipeline from the control port to the control cavity and is connected with the air inlet; the traction force control valve has a first working state, and in the first working state, the control port is communicated with the control cavity through a first channel of the traction force control valve; the traction force control valve has a second working state, and in the second working state, the air inlet communicates with the control cavity through a second channel of the traction force control valve. The traction force control valve is integrated on the basis of a common trailer control valve, the braking force of the trailer can be actively controlled according to the vehicle state, active control over the traction force of the trailer is achieved, and the safety of the whole vehicle is improved.
本发明涉及挂车制动技术领域,提供挂车控制阀和挂车制动系统。挂车控制阀包括控制口、继动阀、进气口和第一出气口,控制口连接继动阀的控制腔,进气口和第一出气口分别连接继动阀的制动腔;还包括牵引力控制阀,设置在控制口通往控制腔的管路中、并连接进气口;牵引力控制阀具有第一工作状态,于第一工作状态,控制口经牵引力控制阀的第一通道连通控制腔;牵引力控制阀具有第二工作状态,于第二工作状态,进气口经牵引力控制阀的第二通道连通控制腔。本发明在普通的挂车控制阀的基础上集成牵引力控制阀,能够根据车辆状态主动对挂车的制动力进行控制,实现挂车牵引力主动控制,提高整车安全性。
