As shown in fig. 1, the structure of the hinge plate protection system of the hinged BRT bus is schematically shown, and the protection system is divided into an electric control part and an air path part.
The electric control part comprises an angle sensor F arranged in the middle of the hinge plate, the angle sensor is connected with a controller of the instrument panel H, and the controller controls the solenoid valve B to be electrified and powered off.
The air circuit part comprises an air storage cylinder A, an electromagnetic valve B and a relay valve D, wherein an air inlet 1 of the electromagnetic valve B is connected with an air outlet of the air storage cylinder A, and an air outlet 2 of the electromagnetic valve is connected with an air inlet 4 of the relay valve D.
In the scheme, under normal conditions, the electromagnetic valve B is a normally-closed electromagnetic valve and is in a power-off state, the air inlet 1 of the electromagnetic valve B is closed, and the air outlet 2 is communicated with the air outlet 3.
When the BRT bus is reversing or steering, and the angle of the hinge plate reaches 47-52 degrees (180-52 degrees when the angle of the hinge plate is normal), an angle sensor F arranged in the middle of the hinge plate recognizes the signal and sends the angle signal to a controller of an instrument panel H, the controller is electrified to an electromagnetic valve B through a CAN line control signal, an air outlet 3 of the electromagnetic valve B is closed, an air inlet 1 is opened, the air inlet 1 is communicated with an air outlet 2, air paths at two ends of the electromagnetic valve B are communicated, and an air storage cylinder A is ventilated to a relay valve 4 through the electromagnetic valve B. The air enters the air inlet 4 of the relay valve D, and pushes the piston in the relay valve D to compress the air in the relay valve D and enter the brake air chamber, so that the purpose of braking the rear axle is achieved. When the braking is released, the electromagnetic valve B is powered off, the air inlet 1 is closed, the air outlet 2 is communicated with the air outlet 3, air in the braking air chamber is discharged out of the atmosphere through the air outlet 3 of the relay valve D, and air above the piston of the relay valve D returns to the electromagnetic valve B and is discharged out of the atmosphere through the air outlet 2 and the air outlet 3.

When the angle of the hinge disc reaches 47-52 DEG, the electromagnetic valve B is electrified, the air inlet 1 and the air outlet 2 of the electromagnetic valve B are communicated with the air of the air reservoir A, and the air flows through the two-way valve C through the electromagnetic valve B, the piston in the two-way valve C is pushed to the 11 ports of the two-way valve C, so that the 11 ports of the two-way valve C are closed, the 12 ports and the 2 ports of the two-way valve C are communicated, and the air is led to the relay valve D, thereby achieving the purpose of braking.
When the BRT bus brakes, compressed air from the brake master cylinder E flows through the two-way valve C and enters the relay valve D, at the moment, a piston in the two-way valve C pushes towards the 12 ports of the two-way valve, and the 11 ports of the two-way valve are communicated with the 2 ports of the two-way valve, so that the purpose of braking is achieved.
