The invention discloses a tractor air brake hill-start auxiliary system, and relates to the field of automobile air pressure valve control. The system comprises a two-way check valve, a brake foot valve, an air reservoir and a relay valve for controlling airflow to flow into a brake air chamber to realize wheel end brake, wherein the relay valve comprises a front axle relay valve, a driving shaftrelay valve and a trailer brake control valve; the two-way check valve is composed of two air inlets and one air outlet and comprises a front axle braking two-way check valve body, a driving shaft braking two-way check valve body and a trailer braking two-way check valve body; and an air inlet of the brake foot valve is connected with the air reservoir. The tractor air brake hill-startC1 auxiliarysystem can effectively avoid the risk that the vehicle slides on the slope.
