Specifically, when the tractor is not towing the trailer, the port P of the two-position three-way valve 206 is closed, and the port T of the two-position three-way valve 206 and the port a of the two-position three-way valve 206 are communicated, and at this time, the compressed gas in the gas supply device 100 is discharged from the first outlet of the gas supply device 100 and enters the tractor gas cylinder 201 and the trailer gas cylinder 207, respectively. When the automobile needs to be braked, the brake pedal is stepped, that is, the master cylinder 204 is opened, the compressed gas in the tractor gas cylinder 201 is discharged from the control gas outlet of the tractor gas cylinder 201 as the control gas pressure, and enters the master cylinder 204 through the control gas inlet of the master cylinder 204, because the port P of the two-position three-way valve 206 is in the closed state, the port T of the two-position three-way valve 206 is in the communication state with the port a of the two-position three-way valve 206, and the control gas pressure in the master cylinder 204 is discharged only from the second control gas outlet of the master cylinder 204, wherein a part of the control gas pressure enters the relay valve 202 through the two-position three-way valve 206 to open the relay valve 202, the compressed gas in the tractor gas cylinder 201 is discharged from the drive gas outlet of the tractor gas cylinder 201 as the drive gas pressure, and the drive gas pressure enters the brake air chamber 203 through the relay valve 202, and the brake mechanism is driven by the brake air chamber 203 to brake the tractor. It should be noted that the opening of the relay valve 202 is controlled by the input air pressure into the controller inlet, i.e. the larger the control air pressure, the larger the opening of the relay valve 202, the larger the output driving air pressure, and the larger the corresponding tractor braking force. The other part of the control air pressure enters the trailer valve 208 to open the trailer valve 208, the compressed air in the trailer air storage cylinder 207 is taken as the driving air pressure to be discharged from a driving air outlet of the trailer air storage cylinder 207, the driving air pressure enters the trailer service brake device 209 through the trailer valve 208, and the trailer service brake device 209 performs the braking action. It should be noted that the trailer service brake 209 is kept consistent with the braking of the tractor vehicle whether the tractor vehicle is towing the trailer or not, so as to ensure the balance and stability of the control air pressure output by the master cylinder valve 204.
When the tractor pulls the trailer, the port P of the two-position three-way valve 206 and the port a of the two-position three-way valve 206 are in a communicated state, and the port T of the two-position three-way valve 206 is in a closed state, at this time, the compressed gas in the gas supply device 100 is discharged from the first outlet of the gas supply device 100 and enters the gas cylinder 201 for the tractor and the gas cylinder 207 for the trailer respectively. When the automobile needs to be braked, the brake pedal is stepped, that is, the master brake valve 204 is opened, the compressed gas in the tractor gas storage cylinder 201 is used as the control gas pressure and is discharged from the control gas outlet of the tractor gas storage cylinder 201, and enters the master brake valve 204 through the control gas inlet of the master brake valve 204, and because the port P of the two-position three-way valve 206 and the port a of the two-position three-way valve 206 are in a communicated state, the port T of the two-position three-way valve 206 is in a closed state. A part of the control air pressure in the master cylinder valve 204 is discharged from the first control air outlet of the master cylinder valve 204, and enters the relay valve 202 through the proportional valve 205 and the two-position three-way valve 206 in sequence to open the relay valve 202, the compressed air in the tractor air cylinder 201 is discharged from the drive air outlet of the tractor air cylinder 201 as the drive air pressure, the drive air pressure enters the brake air chamber 203 through the relay valve 202, and the brake mechanism is driven by the brake air chamber 203 to brake the tractor.

Since the control air pressure is regulated by the proportional valve 205 before entering the relay valve 202 when the tractor pulls the trailer, the pressure of the control air pressure discharged from the first control air outlet of the brake master valve 204 is reduced by the proportional valve 205, and the opening degree of the relay valve 202 is reduced to reduce the driving air pressure output by the relay valve 202, and accordingly the braking force of the tractor is reduced, so that the braking force of the tractor is not greater than that of the trailer. Therefore, the deceleration of the tractor during braking is reduced to be not greater than the braking deceleration of the trailer, the coordination of the braking forces of the tractor and the trailer is realized, and the condition that the speed of the trailer is greater than the speed of the tractor to cause folding during braking to influence the safety of service braking is avoided.
