The pump cover is internally fixed with a spring base, a spring is sleeved on the spring base, the upper end of the spring is matched with a pressing plate, the pressing plate is matched with a pump plug, and the pump plug is matched with a ring shaft in the pump body.

The pump body still be equipped with a manual brake connecting pipe outward, manual brake connecting pipe be in the same position with the connecting pipe.

The upper cover be equipped with three outlet duct, three outlet duct can connect three braking stall.

The valve core is arranged between the upper cover and the lower cover, a plurality of layers of convex shafts are arranged on the valve core, and the convex shafts are provided with vent holes.

The lower cover is provided with a plurality of air outlet pipes, and the side edges of the air outlet pipes are also provided with regulating valves.

The lower cover is internally provided with a compression spring which is matched with the valve core, and the compression spring is buckled on a convex shaft of the valve core.

The invention has the beneficial effects that: compared with the prior art, the double-boosting wheel cylinder integrated valve is connected with the hand brake integrated valve into a whole through the brake wheel cylinder, so that the brake wheel cylinder directly acts on the hand brake integrated valve, and a plurality of air outlet pipes on the hand brake integrated valve directly act on each tire, and the double-boosting wheel cylinder integrated valve has the advantages of good brake effect, stable brake and the like.
