The working principle is as follows: when the vehicle normally runs, the gas in the front axle gas storage cylinder 1 is connected with the gas inlet 13 of the hand brake switch and the gas inlet 19 of the front axle parking valve and respectively enters the hand brake switch 2 and the front axle parking valve 4, when the hand brake switch 2 is opened, the gas inlet 13 is communicated with the gas outlet 14 in a pneumatic mode and enters the relay valve 3 through the gas outlet 14 of the hand brake switch and the control port 15 of the relay valve; then the split gas is split by a gas outlet 16 of the relay valve, and the split gas respectively enters a front axle parking valve 4 and a rear axle parking valve 5 through a hand brake interface 18 of the front axle parking valve and a hand brake interface 22 of the rear axle parking valve; at the moment, the air pressure at the hand brake interface 18 of the front axle parking valve pushes the cylinder in the front axle parking valve 4 to the air inlet 19 of the front axle parking valve, and the air passage leading to 21 is sealed 19, so that when the vehicle is braked, the air in the master cylinder controller 12 can enter the front axle parking valve 4 through the control port 20 for normal vehicle braking and enter the brake cylinder 7 through the air outlet 21, and the brake cylinder 7 performs braking action; similarly, because the air inlet 23 of the rear axle parking valve is connected with the rear axle air reservoir 6, the air pressure at the hand brake interface 22 of the rear axle parking valve pushes the cylinder in the rear axle parking valve 5 to the air inlet 23, the seal 22 leads to the air passage of the air reservoir 23, so that during driving and braking, the air in the master cylinder controller 12 can enter the rear axle parking valve 5 through the control port 24 and enter the spring brake cylinder 8 through the air outlet 25 and the brake air chamber port 28 of the spring brake cylinder, and the spring brake cylinder 8 performs braking action. When the vehicle is parked, the hand brake switch 2 is pulled, so that the gas in the front axle gas cylinder 1 cannot enter the relay valve 3; at the moment, the air pressure at the air inlet 19 of the front axle parking valve pushes the cylinder in the front axle parking valve 4 to the hand brake interface 18 of the front axle parking valve, and the hand brake interface 18 is sealed; meanwhile, the air pressure of the front axle parking valve 19 enters the brake cylinder 7 from the air outlet 21, and the brake cylinder 7 performs braking action and parking; similarly, the air pressure at the air inlet 23 of the rear axle parking valve pushes the cylinder in the rear axle parking valve 5 to the hand brake interface 22 thereof, the hand brake interface 22 is sealed, and meanwhile, the air pressure of the rear axle parking valve 5 enters the brake air chamber port 28 of the spring brake cylinder from the air outlet 25 thereof for braking.
It should be noted that the air pressure of the front axle air reservoir 1 passes through the hand brake switch 2 and passes through the front wheel parking valve 4 and the rear wheel parking valve 5, when the air pressure is insufficient, the braking and parking effect is affected, so the relay valve 3 is arranged. The relay valve 3 works as an independent mechanism and is controlled by the hand brake switch 2.
