End face and inner cavity between distance ultrasonic sensor, specially the first ultrasonic sensor 3e and the second ultrasonic sensor
8e。
Gas source includes storage cylinder 1, and the bottle body 1b of storage cylinder 1 is equipped with the storage cylinder pressure sensor for detecting its pressure
1a.Solenoid valve block specifically includes two two-position three-way valves and two 2/2-way valves and connect with two two-position three-way valves
Exhaust valve.Controller 6 is equipped with for the interface with each pressure sensor and ultrasonic sensor control connection, controller
The interface for connecting with the solenoid valve control in each solenoid valve block is additionally provided on 6 simultaneously, these interfaces are respectively that power supply connects
Mouth a, power interface b, the first cylinder first pressure sensor interface c, the first cylinder second pressure sensor interface d, the second gas
Cylinder first pressure sensor interface e, the second cylinder second pressure sensor f, storage cylinder pressure sensor interface g, the first ultrasound
Wave sensor interface h, the second ultrasonic sensor interface i.
Stabilizer bar Rigidity Matching is carried out using the stabilizer bar roll stiffness matching test device of the utility model
During test, controller 6 acquires the displacement of the piston rod of the first double-acting cylinder 3 and the second double-acting cylinder 8, controller
The angle of heel size of vehicle body is calculated according to the variable quantity of vehicle parameter and two cylinders.It is changed according to the roll stiffness set
The size of the roll force under the angle of heel is calculated, thus the control defeated active force identical with the roll force size of two cylinders.
The concrete operating principle of gas circuit is controlled referring to Fig. 2, wherein the first working hole and the second working hole respectively correspond cylinder
Epicoele and cavity of resorption, connection be connected on epicoele control valve and cavity of resorption control valve, meanwhile, epicoele control valve and cavity of resorption control
Valve passes through epicoele intake valve respectively and cavity of resorption intake valve is connected to air inlet.
A, B mouth of first and second solenoid valve block are separately connected the upper and lower cavity of left and right cylinder, state, define for convenience here
The cylinder of first solenoid valve block connection is left hand cylinder, and the cylinder of second solenoid valve group connection is right cylinder, 6 basis of controller
The roll stiffness value of detection information and design calculates the power output of left and right cylinder, and according to current cylinder pressure size（For
Facilitate expression, here labeled as left cylinder two-way pressure PL0 and PL1, right cylinder two-way pressure PR0, PR1）, calculate in left and right cylinder
Simultaneously left cylinder two-way pressure PL0 ' and PL1 ', right cylinder two-way pressure PR0 ', PR1 ' is marked in the setting air pressure of cavity of resorption.Comparison setting
The size of air pressure and current gas pressure, controller realize that the pressure of left and right cylinder controls by the control to the first and second solenoid valve block；
By taking left cylinder as an example：
When PL0 ' is greater than PL0, epicoele needs to improve pressure, the epicoele control valve M1 of the first control valve group be located at air inlet position,
Epicoele intake valve M2 is located at connection position, and A mouthfuls are connected to air inlet P, and upper cavity pressure improves.
When PL0 ' is less than PL0, epicoele needs to reduce pressure, the first control valve group epicoele control valve M1 be located at exhaust position, on
Chamber intake valve M2, which is located at, disconnects position, and A mouthful are connected to exhaust valve and are exhausted, upper cavity pressure reduction.
Similar, when PL1 ' is greater than PL1, the cavity of resorption control valve N1 of the first control valve group is located at air inlet position, cavity of resorption intake valve
N2 is located at connection position, and B mouthfuls are connected to air inlet P, and lower cavity pressure improves；
When PL1 ' is less than PL1, the first control valve group cavity of resorption control valve N1 is located at exhaust position, cavity of resorption intake valve N2 is located at disconnection
Position, B mouthfuls are connected to exhaust valve and are exhausted, cavity of resorption pressure reduction；

Position, epicoele intake valve M2, cavity of resorption intake valve N2 are adjusted to disconnection position.
Right cylinder pressure controling mode is similar with left side, is not repeating.
The independent control of the cavity pressure up and down of cylinder can realize the quick formation of cylinder upper and lower cavity pressure difference, in addition, working as vehicle
When rolling, cylinder has carried out stretching or compression movement under the drive of Suspension movement, cylinder interior gas due to volume variation,
Itself also produces pressure difference, this pressure difference resists Suspension movement, consistent with control pressure difference, is beneficial to the quick of pressure adjustment
It realizes.The side tilt angle of the stabiliser bar of different-stiffness is different from the functional relation that anti-side is gone all out, and these functional relations are all
Definite value, when needing the stabiliser bar to different-stiffness to carry out match test, it is only necessary to adjust the function of the control system of controller
Relationship.
Pressure and the holding that the working chamber of two telescoping cylinders is controlled by control system, enable telescoping cylinder to export and set
The anti-side that the stabilizer bar of specification generates is gone all out identical active force, when the stabilizer bar for needing to carry out different roll stiffness
Match test when, different size can be generated by the operating pressure of working chamber that control system adjusts telescoping cylinder
Anti-side go all out, to complete to use the stabilizer bar roll stiffness to the match test of the stabilizer bar of different rigidity
Matching test device avoids the stabilizer bar of replacement different rigidity, cumbersome, match test caused by solving therefore
Problem at high cost.
