Cross and detect the attachment means between rod member and the first control arm to cause the first control arm to carry out at the swing of any angular position
During reason, detection rod member can keep good annexation between the first control arm；At the same time, rod member upper end is detected with
The setting of the Auxiliary support rod member at end then may be such that detection rod member is carried out in motion process relative to the first control arm, pass through auxiliary
Supporting bar for the first control arm to carry out auxiliary propulsion processing, with the transport vehicle being directed under complex road condition in this application
Instantaneous height control device according to its internal part moving situation to judge the change of the instantaneous height of vehicle when so that the first control
Reset effect of the arm processed in the case where detection rod member promotes further is ensured, while can also avoid detecting rod member directly for the
One control arm is promoted and damage phenomenon occurs in connecting portion caused by possibility.
Using the haulage vehicle instantaneous height control device being directed under complex road condition of above-mentioned technical proposal, it is in actual work
It can be detected during work based on the 3rd control arm being connected on vehicle body vehicle bridge with the bodywork height state for vehicle,
It is embodied in：When vehicle by load is overweight and the factor such as the transient change of low-lying road conditions is influenceed when, there is car in vehicle
Body sinkage, the 3rd control arm carry out downward vertical motion therewith, and when vehicle is by load or fluctuating road conditions
When the factors such as transient change influence, there is vehicle body and moves up phenomenon in vehicle, and the 3rd control arm can carry out upward vertical fortune therewith
It is dynamic.Annexation between first control arm, the second control arm and the 3rd control arm then can be according to the motion of the 3rd control arm
State is entered with causing the second control arm to be swung up and down with the 3rd control arm relative to the link position of itself and the first control arm
And the adjustable side of the first control arm is driven to carry out horizontal hunting processing relative to its control terminal.
During above-mentioned first control arm is swung, its intake valve or vent valve can be promoted in inlet plenum or
Processing is opened and closed in gas bleed chamber；By taking the motion process of intake valve as an example, when the first control arm is towards inlet chamber indoor sport
During so that it being contacted with intake valve, intake valve is opened under its influence, with the air compressor for causing intake valve to be connected
Air-flow is inputted in towards air spring, so that obtain air spring is able to rise processing under ventilatory effect, to compensate vehicle appearance
Vehicle body sinkage.When vehicle body actual height is resetted under above-mentioned compensating action, the 3rd control arm returns initial shape
State, the second control arm and the first control arm are also in initial position again, and now intake valve is no longer influenced by the first control arm
Control and then can re-close.Conversely, when there is vehicle body rise phenomenon in vehicle, the first control arm, the second control arm and
3rd control arm counter motion, to cause vent valve to repeat the job step of above-mentioned intake valve, cause air after vent valve unlatching
Air in spring is discharged among air, causes the associated components in the height and the application of vehicle body to be returned to normal work shape
State.
The haulage vehicle instantaneous height control device being directed under complex road condition in the application is passing through above working method
While realizing the control and regulation processing for bodywork height, its continuation that can also change for height of vehicle body is entered
Row detection process.When vehicle due to factors such as road condition changes and cause bodywork height occur transient change when, the first control arm with
Above-mentioned working method carries out oscillation adjustment processing, and the first control arm is in the course of the work, and it also may be such that the first control arm institute
The detection chambers of detection rod member towards the correspondence position of connection are moved；The detection piston that detection rod member is connected drives detection
Damping fluid in chamber is flowed by turning on pipeline towards support chamber, to be carried out for the support end body in support chamber
Propulsion is handled.If for bodywork height merely due to when road surface rises and falls and carries out transient change, the amplitude of fluctuation of the first control arm is smaller,
Therefore it can not provide enough propulsion dynamics and forward displacement to detection rod member and detection piston, therefore support the resistance in chamber
Buddhist nun's liquid can not form enough supporting times for support end body, cause support end body to be able to a certain degree of pressure in the starting stage
After contracting, i.e., counter motion can be carried out relative to the pushing direction of damping fluid in the presence of elastomeric spring, make it that damping fluid is anti-
Flowed to via support chamber towards detection chambers, and reverse impetus is formed for detection piston, cause the first control arm
It is returned to initial position rapidly under the reverse impetus of above-mentioned detection piston, and then reversely drives the second control arm, the 3rd
The vehicle bridge of control arm and vehicle is returned to normal operating conditions.
The above-mentioned haulage vehicle instantaneous height control device being directed under complex road condition, it not only can be in the bodywork height of vehicle
Processing is adjusted for bodywork height during being changed, to cause vehicle to be in good stable state in real time, and can
According to the factor and the difference of the continuation of its impact effect that influence bodywork height and then carry out different journeys for bodywork height
The balance adjustment processing of degree, especially causes vehicle to cause the vehicle body stability of vehicle to produce instantaneous become because track rises and falls
During change, you can adjusted in time for bodywork height of the above-mentioned transient change process for vehicle, to ensure vehicle in the above
Moment reduces the risk of its rollover, and can be in the above-mentioned up-and-down surfaced road of vehicle derailing so that the bodywork height of vehicle recovers as early as possible
To normal condition, to ensure that vehicle will not be travelled surely in journey is subsequently run over due to the too high or too low of automobile body to it
It is qualitative to impact.
In addition, the haulage vehicle instantaneous height control device being directed under complex road condition in the application is directed to inlet plenum side
And the set location of different support chambers and support end body is respectively adopted in deflation chamber side, it can be directed to the first control valve
Adjustable side when being moved into inlet plenum and caused by vehicle vehicle body rise phenomenon, to cause the inspection of inlet plenum side
The direction of motion when damping fluid surveyed in chamber is moved into support chamber is identical with vehicle body mass motion direction；And for
The adjustable side of first control valve to gas bleed chamber moved when and caused by vehicle vehicle body reduce phenomenon, it also may be such that
Damping fluid in the detection chambers of deflation chamber side is identical with vehicle body mass motion direction to the direction of motion in chamber is supported；It is above-mentioned
The motion mode of support chamber internal damping liquid can enable its overall transfer efficiency further improve.
