Description
Technical field:
The present invention relates to a kind of controllable damping hydro-pneumatic spring, particularly a kind of wheeled armored vehicle is controlledDamping oil gas spring, belongs to wheeled armored vehicle independent suspension system field.
Background technology:
At present, wheeled armored vehicle suspension system is used hydro-pneumatic spring, its damping element and gas bulletSpring integrated design, taking certain the model Vehicle De L'Avant Blinde By Creussot grinding as basis, the damping of its hydro-pneumatic spring is notAdjustable control, cannot realize and should control damping, bears again gas spring bearing body to valve to beThe larger operating pressure of bringing, thus cannot regulate in real time damping according to pavement behavior, causeBasis power value is less, the defect that adjustable extent is narrow.
Summary of the invention:
The present invention is by the controllable damping element that is medium to magnetic flow liquid and gas spring is integrated establishesMeter, develops a kind of magnetorheological controllable damping hydro-pneumatic spring, and solving the damping of traditional oils air spring cannot be partlyThe problem of active adjustment.
The present invention adopts following technical scheme to realize:
A kind of controllable damping hydro-pneumatic spring, comprises upper connecting base, ball stud, cylinder barrel, piston rod, floatingMoving piston, lower connecting base and charge valve, cylinder barrel top is provided with MR damper, magnetorheological dampingDevice is connected with the control line being connected with external control system, and pressure measuring tie-in, piston rod are installed on cylinder barrelAnd between MR damper, can form between working chamber and cylinder barrel and form compensated cavity, working chamber and benefitRepay in chamber and be filled with magnetic flow liquid, the two is connected by hydraulic tube, and pressure limiting valve is installed on piston rod;
MR damper comprises piston body, coil rack, and coil, cuts apart ring and coil cover plate,In support damper, the piston body of miscellaneous part connects cylinder barrel, and coil rack is insulating materials, coil windingOn it, cut apart ring and be arranged between piston body and coil cover plate.
The invention has the beneficial effects as follows: this controllable damping hydro-pneumatic spring is by controllable damping element and air bulletSpring becomes one, and double flexible member and the damping element of doing plays the guide effect of suspension simultaneously, except holdingBe subject to the vertical load of vehicle, ensure that outside the correct guidance of the upper and lower motion of draft hitch, also possessing can rootAccording to pavement behavior, damping is carried out the function regulating in real time. Become basic controllable damp device with magnetic currentDependable performance, basic power value is larger, and adjustable extent is wide. Effectively improve wheeled armored vehicle flatAll cross-country speed, or it is equal under identical speed and pavement conditions, to effectively reduce body oscillating accelerationRoot value.
The present invention is mainly applicable to the independent suspension system of heavy Vehicle De L'Avant Blinde By Creussot and modification vehicle thereof.
Brief description of the drawings:
Fig. 1 is controllable damping hydro-pneumatic spring structural representation of the present invention;
Fig. 2 is controllable damping hydro-pneumatic spring MR damper structural representation.
Detailed description of the invention:
As Figure 1-Figure 2, controllable damping hydro-pneumatic spring upper connecting base 1 connection body and ball stud 2,MR damper 3 is arranged on cylinder barrel 5 tops, by control line 11 be connected with control system, cylinderCylinder is provided with pressure measuring tie-in 12 on 5, hydraulic tube 4 connects working chamber 13 and compensated cavity 14, pressure limiting valve6 be arranged on piston rod 7, floating piston 8 is arranged on piston rod 7 inside, lower connecting base 9 connectsKnuckle, charge valve 10 are arranged on lower connecting base.
In MR damper 3, piston body 15 connects miscellaneous part in cylinder barrel 5 supporting damping device,Coil rack 16 is insulating materials, and coil 18 is wound on it, cuts apart ring 17 and is installed on piston body 15And between coil cover plate 19, thereby damping adjusting device parallel clearance damping adjusting.
This controllable damping hydro-pneumatic spring upper end is connected with car body by Connection Block 1, and lower connecting base is passed through in lower end9 cylindricals and knuckle endoporus interference fit, and fix with fixed head, independent suspension frame unit born simultaneouslyFlexible member and damping element.
Controllable damping hydro-pneumatic spring structure is shown in Fig. 1, and Connection Block 1 is adopted with controllable damping hydro-pneumatic spring main bodyConnect with ball stud 2, while adapting to wheel hop, the variation of castor, leaning angle, increases controlledThe vertical stiffness of damping oil gas spring entirety, reduces and swings rigidity, alleviates additional side force. MagnetorheologicalDamper 3 is arranged on cylinder barrel 5 tops for parallel slit structure, by what introduced by external control systemControl line 11 is controlled by the current strength of coil 18, to change the method for magnetic flux, changes magnetic currentBecome liquid 20 viscosity, thereby reach the object of controlling damping. Pressure limiting valve 6 is installed on piston rod 7,Can in the time that system pressure acquires a certain degree, open valve release in pressure measuring tie-in 12 tests, protect magnetorheologicalDamper 3, avoids damaging because of greater impact. Can between piston rod 7 and MR damper 3Form working chamber 13, with cylinder barrel 5 between form compensated cavity 14, in working chamber 13 and compensated cavity 14Be filled with magnetic flow liquid 20, the rigidity hydraulic tube 4 of loop effect has been installed between the two. Piston rod 7Floating piston 8 is inside housed, cuts apart air chamber and magnetorheological liquid chamber, in air chamber, be filled with by charge valve 10High pressure nitrogen 21, as gas spring bearing body weight. By jointly forming controlled resistance with upper-partBuddhist nun's hydro-pneumatic spring, ensures that vehicle is in the time of different road traveling, realizes half initiatively control of suspension dampingSystem.
