Effect improves the versatility that this method uses, also, adjusting method is simple and convenient.
Between height of floor of the floor at the height of rail level and other end doors to rail level at an end door
Difference when being less than preset range, by controlling levelling valve 6 blow vent 4 of air spring 3 is connected with charger 10,
Pair air spring 3 corresponding with the floor at the end door is inflated；The height of floor at an end door to rail level
When difference between the height of the floor at other end doors to rail level is higher than preset range, by controlling levelling valve 6
The blow vent 4 of air spring 3 is set to be connected with the exhaust outlet of levelling valve 6, pair air corresponding with the floor at the end door
Spring 3 is exhausted.
It is understood that a car body 1 is corresponding with two frameworks 2, two air springs 3 are provided with each framework 2.
Therefore, a car body 1 is corresponding with 4 air springs 3.
Preferably, charger 10 is reservoir.
Preferably, preset range is -3mm~3mm.That is, in step S1, regulation air spring 3 four mounting surfaces to
During the measurement height of rail level, it is ensured that the margin of tolerance between four groups of measured values is -3mm~3mm；It is multiple adjusting in step S4
Floor at end door to rail level height when, it is ensured that the margin of tolerance between four groups of measured values is -3mm~3mm.Certainly,
Other numerical value can be chosen as preset range, no longer tire out one by one state and within protection domain herein.
In step S2, mark is positioned at position of the oil storage cylinder close to dust cover that two be vertical damper.It can also be arranged at
Other positions, no longer introduce one by one herein.
In step S2, by being that paste color mark reaches mark air spring 3 on the oil storage cylinder of vertical damper to two
The effect of height in deflation status.Wherein, colored marking can be red, yellow or the sign of the random color such as orange.
Further, in step S3, under the inflated condition of air spring 3 span of the time of pressurize be 5min~
15min.That is, under the inflated condition of air spring 3, pressurize 5min~15min, then, it is ensured that the working depth of air spring 3
No longer change.Wherein, the dwell time according to the structure of air spring 3 and the weight of car body 1 depending on, when can also be by pressurize
Between span be arranged to other number ranges, also within protection domain.
In height adjusting method provided in an embodiment of the present invention, the end door quantity on car body 1 is four.That is, in step
, it is necessary to adjust floor at four end doors to the tolerance between the height of rail level within preset range in S4.
Air suspension regulating system also includes the height control lever 7 of the control switch of levelling valve 6 and controlled with height
The height adjusting link 8 of the free end connection of lever 7, height adjusting link 8 are vertically arranged；Levelling valve 6 is located on car body 1, high
Degree adjustment bar 8 is located on framework 2；Levelling valve 6 is h to the height of framework 2, and the height of height adjusting link 8 is h0；
In step S4, by the height h for adjusting height adjusting link 80, the switch of control levelling valve 6；
Work as h=h0When, height control lever 7 is in horizontality, and levelling valve 6 is closed；
As h ＞ h0When, the free end of height control lever 7 is tilted down, and levelling valve 6 is opened by the row of air spring 3
The state of gas, until height control lever 7 is in horizontality；
As h ＜ h0When, the free end of height control lever 7 is inclined upwardly, and levelling valve 6 is opened to be entered to air spring 3
The state of gas, until height control lever 7 is in horizontality.
Car body 1 is correspondingly arranged with two frameworks 2, and the adjusting method of height control lever 7 is as follows：First adjust vehicle one end structure
The height of height adjusting link 8 on frame 2 is to operational height under inflated condition, then the height adjusted on vehicle other end framework 2 is adjusted
The whole height of bar 8 is so adjusted to height of the height floor away from rail level by end door everywhere repeatedly to operational height under inflated condition
Degree difference adjustment is within the margin of tolerance.
Pass through air suspension pipeline connection, air suspension pipeline between the air bag of two air springs 3 on each framework 2
Differential valve is provided with, the air bag inner air pressure of two air springs 3 is controlled in the range of design tolerance.Wherein, design is public
Poor scope is no longer discussed in detail herein depending on concrete structure.
In step S1, mistake of the tolerance within preset range between measurement height of four mounting surfaces to rail level is adjusted
Cheng Zhong, it is adjusted by adding and subtracting pad in the junction of 3 times mounting surfaces of air spring and framework 2.In air spring 3
When mounting surface is less than the minimum value of preset range to the tolerance between the measurement height of rail level, pacified by 3 times to the air spring
Dress face and the junction increase pad of framework 2, improve the mounting surface of air spring 3, and then ensure the mounting surface of the air spring 3
To the tolerance between the measurement height of rail level within preset range；An air spring 3 mounting surface to rail level measurement
When tolerance between height is higher than the maximum of preset range, by the junction of 3 time mounting surfaces of the air spring and framework 2
Pad is reduced, reduce the mounting surface of air spring 3, and then ensure the mounting surface of the air spring 3 to the measurement height of rail level
Between tolerance within preset range.
During the tolerance between adjusting measurement height of four mounting surfaces to rail level is within preset range, plus-minus
The method that pad is adjusted：
S11：Car body 1 is added and subtracted in diagonal position and padded in diagonal distortion on four air springs 3；
S12：Car body 1 is low in side on four air springs 3 and when opposite side is high, reached in side position plus-minus pad
The margin of tolerance.
By the above-mentioned means, the comfort level to plus-minus pad regulation can be effectively improved.
By taking levelling valve 6 provided in an embodiment of the present invention as an example, in the operating method that the gas leakage of levelling valve 6 detects such as
Under：Sa1：It is horizontal the height control lever 7 of levelling valve 6；Sa2：Close the isolation cock with steam vent, pressure

Firmly, do not allow bubble occur；Sa 4：Open the isolation cock with steam vent and isolation cock.The air pressure of pressure gauge rises to 8bar；
Reading on pressure gauge is down to 0bar；Sa 5：The exhaust outlet for isolating cock is sealed with liquid soap, does not allow bubble occur.
Row's charge inspection method of levelling valve 6 is as follows：Sb1：Close isolation cock；Sb2：By height control lever 7
Free end tilt down 15 °+5 ° (deviate inflation directions), the air pressure and pressure gauge reading in charger 10 will rise, gas
It is pressed in 3.5s ± 0.5s and rises to 4.55bar from 4bar；Sb3：The free end of height control lever 7 is tilted down 15 °+5 °
(deviate steam vent direction), the reading on air pressure and pressure gauge in charger 10 are down in 5s ± 1s from 4.55bar
4bar；Sb4：Isolation cock is opened, the free end of height control lever 7 is inclined upwardly and (deviates inflation direction again), specifically
Pressure rises to 4.55bar in 1.8s ± 0.5s from 4.0；Sb5：The free end of height control lever 7 is tilted down (inclined again
From steam vent direction), pressure is down to 4bar in 3s ± 1s by 4.55bar.
Preferably, height adjusting link 8 is expansion link.In order to adjust the height of height adjusting link 8.
In the present embodiment, height adjusting link 8 and the free end of height control lever 7 are hinged.
The gas outlet of charger 10 is connected with the air inlet of levelling valve 6 by inflation line 9, air spring 3
Blow vent 4 is connected with the gas outlet of levelling valve 6 by air suspension pipeline 5.
As shown in Fig. 2 each framework 2 is corresponding with two levelling valves 6, and levelling valve 6 and air spring 3 are one by one
It is corresponding.It is understood that each framework 2 is corresponding with two air springs 3, therefore, in the present embodiment, levelling valve 6
