The invention belongs to the technical field of commercial vehicle parking braking, and discloses a pneumoelectric double-control auxiliary parking valve and a commercial vehicle braking system, the pneumoelectric double-control auxiliary parking valve comprises a two-way check valve, a pneumoelectric double-position three-way valve and an electric double-position three-way valve, a driving air inlet of the two-way check valve is connected with a driving foot valve control air; an air outlet of the two-way check valve is connected with a traveling relay valve or an air chamber, and an exhaust control port of the pneumatic control two-position three-way valve is connected with control air of a vehicle parking manual valve; and a control port of the electric control two-position three-way valve is connected with a self-resetting switch for controlling auxiliary parking of the vehicle. Pneumatic control and electric control are matched to control parking, and the graded parking function is achieved; and an original commercial vehicle braking system does not need to be changed, dependence on electricity is reduced, the parking reliability is improved, mechanical braking and inflation braking are well integrated, and the parking capacity and the parking stability of a vehicle are improved.

    本发明属于商用车辆驻车制动技术领域,公开了一种气电双控辅助驻车阀和商用车制动系统,气电双控辅助驻车阀包括双通单向阀、气控两位三通阀和电控两位三通阀,双通单向阀行车进气口与行车脚阀控制气相连,双通单向阀出气口与行车继动阀或气室相连,气控两位三通阀排气控制口与车辆驻车手动阀控制气相连;电控两位三通阀控制口与车辆控制辅助驻车的自复位开关相连。本发明采用气控和电控配合控制驻车,实现分级驻车功能;无需改变原有商用车辆制动系统,既减少对电的依赖性,提高驻车可靠性,又将机械制动和充气制动很好的集成在一起,提高车辆驻车能力和驻车稳定性。
