Discharge chamber 7 is connected to, and exhaust solenoid valve 25 receives control information, and control discharge plenum 19 is communicated with the atmosphere.Pressure maintaining gas chamber 18 with it is defeated
Discharge chamber 7 is connected to, and 18 gas pressure of pressure maintaining gas chamber is identical as output 7 gas pressure of gas chamber, under the action of diaphragm plate spring 23, the
One anti-skidding diaphragm plate 21 remains turned-off, and output gas chamber 7 and brake chamber 17 are mutually indepedent, brake chamber 17 at the first anti-skidding diaphragm plate 21
Closing.Discharge plenum 19 is communicated with the atmosphere, and 19 gas pressure of discharge plenum is identical as atmosphere, and 19 gas pressure of discharge plenum is lower than
Second anti-skidding 22 other side brake chamber of diaphragm plate, 17 gas pressure, the second anti-skidding diaphragm plate 22 are opened to 19 side of discharge plenum, system
Room 17 of taking offence is connected to anti-skidding exhaust passage 20, and brake chamber 17 is vented to anti-skidding exhaust passage 20.At this point, 17 row of brake chamber
Gas pressure is lower than checking cylinder gas pressure after gas, and the anti-skidding diaphragm plate 10 of third is opened to 17 side of brake chamber, checking cylinder gas
It is discharged by brake gas from anti-skidding exhaust passage 20, brake-cylinder pressure reduces, and brake force reduces, and prevents wheel and track from occurring
Sliding leads to wheel tread flat.
Electronic brake control unit according to sensor information be calculated checking cylinder brake force it is suitable when, aerobraking control
Unit enters pressure maintaining mode.Under pressure maintaining mode, pressure maintaining solenoid valve 24 receives control information, control pressure maintaining gas chamber 18 and output gas chamber
7 connections, exhaust solenoid valve 25 receive control information, and control discharge plenum 19 is connected to output gas chamber 7.At this point, the first non-skid film
Plate 21 and the second anti-skidding diaphragm plate 22 are in closed state, and brake chamber 17 is completely isolated and keeps gas pressure constant.Accordingly
, 17 gas pressure of brake chamber is identical as checking cylinder gas pressure, and third diaphragm plate 10 is closed, and checking cylinder gas pressure is kept not
Become, keeps current braking effort.
Aerobraking control unit detects the gas pressure information of each branch, deceleration of electrons control by sensor module 4
Unit receives information and calculates, and control information will be obtained after calculating and is sent to aerobraking control unit, controls solenoid valve module 5
Complete the braking of rail vehicle and anti-skidding.Sensor module 4 and solenoid valve module 5 form control closed loop, realize output pressure
Closed-loop control, guarantee rail vehicle braking stablize.
