Three altitude valves 23 respectively correspondence be fixed on propons, drive axle, on the vehicle frame near follow-up bridge, first normally open solenoid valve 51,
Second normally open solenoid valve 52, the first normally closed solenoid valve 61, the second normally closed solenoid valve 62 are each attached on the vehicle frame of follow-up bridge adnexa；
First normally open solenoid valve 51, the second normally open solenoid valve 52, the effect of the first normally closed solenoid valve 61 and the second normally closed solenoid valve 62 are
Gas circuit is controlled to connect and close by the signal of telecommunication of controller；The effect of the first pressure limiting valve 71 and the second pressure limiting valve 72 be control with
The pressure at expulsion of dynamic bridge air bag, when gas pressure is higher than pressure limiting valve setting value, gas passage connected by pressure limiting valve；Work as gas pressure
During less than pressure limiting valve setting value, pressure limiting valve cuts out gas passage；The effect of deafener 9 is that the aerofluxuss for reducing follow-up bridge air bag are made an uproar
Sound.
Triple-axle coach axle load of the present invention distributes the operation principle of control system：
During normal vehicle operation, the first normally open solenoid valve 51 and the second normally open solenoid valve 52 are normally opens, the first normally closed electromagnetism
Valve 61 and the second normally closed solenoid valve 62 are normally offs；When needing to increase drive axle limit driving force, controller control first
Normally open solenoid valve 51 and the second normally open solenoid valve 52 are off-state, therefore between the second altitude valve 22 and the left air bag 45 of follow-up bridge
Gas circuit disconnected by the first normally open solenoid valve 51, the gas circuit between third height valve 23 and the right air bag 46 of follow-up bridge is normally opened by second
Electromagnetic valve 52 disconnects；Meanwhile, it is on-state that controller controls the first normally closed solenoid valve 61 and the second normally closed solenoid valve 62, therefore
The left air bag 45 of follow-up bridge is connected with the first pressure limiting valve 71, and the voltage limiting value of the first pressure limiting valve 71 is pressed less than the left air bag 45 of follow-up bridge
Power, in the left air bag 45 of follow-up bridge, gas can be discharged from the first deafener 81 after passing through the first pressure limiting valve 71；In the same manner, the right gas of follow-up bridge
In capsule 46, gas can be discharged from the second deafener 82 after passing through the second pressure limiting valve 72；The left air bag 45 of follow-up bridge and the right air bag of follow-up bridge
In 46, gas pressure reduces, and follow-up bridge axle load is transferred to drive axle, and now body gesture controls a propons left side by the first altitude valve 21
The right air bag 42 of air bag 41, propons controls the right air bag 44 of the left air bag 43, drive axle of drive axle with the second normally open solenoid valve 52 to keep,
When cancelling increasing limit driving force operating mode, it is normal that controller controls the first normally open solenoid valve 51 and the second normally open solenoid valve 52
Open state, the first normally closed solenoid valve 61 and the second normally closed solenoid valve 62 are that the normally off, second altitude valve 22 is normally opened by first
Electromagnetic valve 51 is inflated to the left air bag 45 of follow-up bridge, and third height valve 23 is by the second normally open solenoid valve 52 to the right air bag 46 of follow-up bridge
Inflation, altitude valve recovers, to drive axle suspension bags and the control of compliance suspension air bag, to recover normal vehicle operation.
In triple-axle coach axle load distribution control system of the present invention, the calculation procedure of the voltage limiting value of pressure limiting valve is：
A, drive axle suspension bags and follow-up bridge suspension bags type selection calculation
According to the empty fully loaded axle load of drive axle and follow-up bridge（Drive axle axle load is fully loaded with regulation limit value and requires）, in gasbag pressure identical
In the case of, design driven bridge suspension bags and follow-up bridge suspension bags；
B, determine under full-loading condition, drive axle suspension bags and follow-up bridge suspension bags relative pressure；
C, according to limit driving force require, calculate drive axle suspension bags needed for relative pressure, determine drive axle with servo-actuated bridge axle
Lotus ratio, determines follow-up bridge air bag relative pressure, i.e. pressure limiting valve voltage limiting value, and checks this follow-up bridge air bag；
D, checking computations follow-up bridge air bag relative pressure by 3 performance diagram of automatic load Inductance valve and step a calculate empty, full
During load, air bag relative pressure calculates 8 sky of yaw bar assembly, is fully loaded with setting angle；
C, 8 installation length of determination yaw bar assembly
Empty, the fully loaded height change difference of drive shaft plate spring suspension brackets is used as known conditions, and the fully loaded air bag for being calculated by step a is relative
Pressure is used as desired value, while the yaw bar assembly 8 for being calculated using step b is calculated in the setting angle of vehicle sky, full load
8 installation length of yaw bar assembly.
In sum, triple-axle coach axle load distribution control system of the present invention is dropped when needing to increase drive axle limit axle load
Low follow-up bridge gasbag pressure makes follow-up bridge axle load be transferred to drive axle to setting, controls the relative pressure in follow-up bridge air bag
Power, limits servo axis axle load, it is to avoid the driving axle load for being caused using altitude valve or ECAS system is transferred to servo axis in a large number
Problem, improve servo axis service life, reduce servo axis tire wear；And triple-axle coach axle load distribution control of the present invention
System has the characteristics that simple structure, simple installation, low production cost, production efficiency are high.
