Specific implementation mode
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments：
As shown in Figure 1, bus body lift control system includes gas receiver 1 and three gas circuit control modules, each gas circuit
Module can control two air bags simultaneously, and three gas circuit control modules control the left air bag 6 of front axle and the right air bag 7 of front axle, rear axle respectively
Air bag 10 and the right rear gasbag of rear axle 11 before left front air bag 8 and the left back air bag 9 of rear axle, the rear axle right side.
Gas circuit control module includes four-way connection 3, limit altitude valve 4 and automatically controlled lifting valve 5.It includes the to limit altitude valve 4
One air inlet 4-1, the second air inlet 4-12, the first gas outlet 4-21, the second gas outlet 4-22, third gas outlet 4-23 and exhaust
Mouth 4-3.Automatically controlled lifting valve 5 includes the first air inlet 5-11, the second air inlet 5-12, third air inlet 5-13, the first gas outlet
5-21, the second gas outlet 5-22, control mouth 5-4 and exhaust outlet 5-3.
Gas receiver 1 is connected to four-way connection 3, four-way connection 3 respectively with limit the first air inlet of altitude valve 4-1, second into
Gas port 4-12 and automatically controlled lifting valve control mouth 5-4 connections, limit altitude valve the first gas outlet 4-21 and automatically controlled lifting valve first
Air inlet 5-11 connections, limit altitude valve the second gas outlet 4-22 are connect with the second air inlet of automatically controlled lifting valve 5-12, and limit is high
Bottom valve third gas outlet 4-23 is connect with automatically controlled lifting valve third air inlet 5-13；The first gas outlet of automatically controlled lifting valve 5021 and
Two gas outlet 5-22 are connected with two air bags respectively.The break-make relationship of each interface is by electric signal and control in automatically controlled lifting valve 5
Mechanism of the ends the mouth 5-4 high pressure gas collective effect in automatically controlled lifting valve 5 realizes.
Bodywork height automatically controls when normal vehicle operation：At this time in automatically controlled lifting valve 5, the first air inlet 5-11 and first
Gas outlet 5-21 is connected to always, and the second air inlet 5-12 is connected to always with the second gas outlet 5-22, other in automatically controlled lifting valve 5 connect
Mouth is not connected to, and the inflation/deflation that the lifting of bodywork height is controlled air bag by limit altitude valve 4 is realized.When air bag height is less than design
When height value, the first air inlet 4-1 for limiting altitude valve 4 is connected to the first gas outlet 4-21 and the second gas outlet 4-22 simultaneously,
The high pressure gas exported from gas receiver 1 respectively enters electricity by limiting altitude valve the first gas outlet 4-21 and the second gas outlet 4-22
Lifting valve the first air inlet 5-11 and the second air inlet 5-12 is controlled, then passes through automatically controlled lifting valve the first gas outlet 5-21 and 5-22 points
Jin Ru not be in two air bags, airbag aeration, vehicle body lifting.When air bag height is equal to design height value, altitude valve 4 first is limited
Air inlet 4-1 is disconnected with the first gas outlet 4-21 and the second gas outlet 4-22 simultaneously, and air bag is in packing state, without charge and discharge
Gas, vehicle body are stablized in present level.When air bag height is higher than design height value, it is same to limit the first air inlet 4-1 in altitude valve 4
When disconnected with the first gas outlet 4-21 and the second gas outlet 4-22, and the first gas outlet 4-21 and the second gas outlet 4-22 simultaneously with
Exhaust outlet 4-3 is connected to, and gas, which passes through, in corresponding air bag limits height valve outlet 4-3 discharges, air bag deflation, and vehicle body declines.
Bodywork height manually controls：When forcing to be lifted bodywork height, only third air inlet 5-3 in automatically controlled lifting valve 5
It is connected to simultaneously with the first gas outlet 5-21, the second gas outlet 5-22, other interfaces are not connected in automatically controlled lifting valve 5.From gas receiver 1
The high pressure gas of output is successively through four-way connection 3, limit the second air inlet of altitude valve 4-12, limit altitude valve third gas outlet 4-
23, automatically controlled lifting valve third air inlet 5-3 enters in automatically controlled lifting valve 5, then by automatically controlled lifting valve the first gas outlet 5-21 and the
Two gas outlet 5-22 arrive separately at corresponding air bag, airbag aeration, vehicle body lifting.When vehicle body pressure is lifted to setting value, limit
Altitude valve the second air inlet 4-12 and third gas outlet 4-23 is disconnected, and third gas outlet 4-23 is connected to exhaust outlet 4-3, corresponding gas
Gas is discharged by exhaust outlet 4-3 in capsule, air bag deflation, and vehicle body declines；When vehicle body drops below setting value, altitude valve is limited
Third gas outlet 4-23 is disconnected with exhaust outlet 4-3, and the second air inlet 4-12 is connected to third gas outlet 4-23, gas receiver mesohigh
For gas by inflating path to airbag aeration, vehicle body lifting makes bodywork height be maintained in range of set value, forces lifting vehicle body
The limit value of height is realized by internal mechanism control in limit altitude valve 4.
When forcing to reduce bodywork height, only the first gas outlet 5-21, the second gas outlet 5-22 is same in automatically controlled lifting valve 5
When connected with exhaust outlet 5-3, other interfaces are not connected in automatically controlled lifting valve 5, at this point, gas is by exhaust outlet 5-3 in corresponding air bag
It is discharged in air, air bag deflation, vehicle body declines, and the Height that vehicle body declines is determined by the position of limited block in air bag.
Manually control a certain height during vehicle body is parked in pressure lifting and declines：When require vehicle body be parked in pressure lifting with
During decline when a certain height, total interface is not connected in automatically controlled lifting valve 5, and air bag is in packing state, air bag without
Inflation/deflation, vehicle body are maintained at height at that time.
It is emphasized that：The above is only the preferred embodiment of the present utility model, not appoints to the utility model
What formal limitation, any simple modification made by the above technical examples according to the technical essence of the present invention, etc.
With variation and modification, it is still within the scope of the technical solutions of the present invention.
