Embodiment
The active vibration damper of a kind of twin-tub, comprise round cylinder, outside circle cylinder, spring seat (4) is housed, other parts are all in circle cylinder, in circle cylinder, head is equipped with black box (2), piston rod one (1) until justify the middle and lower part of cylinder and be connected to restoration valve component (8), is equipped with of compression valve assembly (9) through black box (2) near restoration valve component (8), the other end of compression valve assembly (9) is at the afterbody justifying cylinder, it is characterized in that, communicated with one-way valve (11) by oil pipe in the other end of the compression valve assembly (9) of the afterbody of circle cylinder, the asphalt channel (5) in round cylinder linked again by one-way valve (11) after electromagnetic valve component (13) by connected pipes (12), in circle cylinder, periphery is also provided with piston rod two (3), piston rod two (3) is provided with dust preventing component (6) in the middle part of periphery, piston rod two (3) bottom, periphery is provided with spring (7), piston rod two (3) periphery afterbody is provided with movable piston (10), piston rod two (3) is connected to movable piston (10) always, spring (7) is between dust preventing component (6) and movable piston (10).Spring (7) diameter is 4mm.Electromagnetic valve component is generally two position two-way valve (13).Have Sealing in the middle of movable piston (10), bottom has nut spacing, and effect is accumulation of energy, in addition, is the effect that lifting piston rod two is played in pressurization to top, and to vibration damper voltage supply above, pressurization makes it reach fuel feeding requirement.
Concrete development:
According to the working principle of vibration damper, we improve vibration damper.
Name Resolution: twin-tub: there is two clutch release slave cylinders not same-action.Active: there is open interface.ACTIVE CONTROL carried out to vibration damper performance, increases, be exaggerated vibration damper performance.
One, invention advantage:
Standard vibration damper feature: have 1, a low frequency range, 2, intermediate frequency zone, 3, high frequency region; Different damping road pavement and the vibrations size of automobile itself decay with impact size.
The active vibration damper advantage of twin-tub:
1, add low frequency range scope, effect comfort level enhances,
2, add the control strong shock resistance of high frequency region, can decay.Car load has the strong impact force of 1 meter of height.Shock absorber structure intensity with functionally can realize damping proportioning (there is this function in luxury car),
3, have turning function, work safety improves,
4, vehicle body lifting function, effect:
1): middle vehicle body of running at high speed reduces, earth-grasping force strong security at the bottom of center of gravity can be good, and the little oil consumption of windage economizes (there is this function in luxury car),
2): the body gesture adjustment when tempo turn, left and right height is different, and center of gravity shifts.
Two, common vibration damper working principle
There is oil cylinder, pilot seal assembly piston rod rebuilt valve compression valve shoe cream room
Working procedure: piston rod and vehicle body and spring chain, also compress when the vibrations on road surface are delivered to spring-compressed piston rod thereupon.1, the oil-feed of rebuilt valve one-way valve opens.2, utilize piston rod to move the change of oil pocket inner volume.Exudate force feed, through compression valve gap or aperture, produces damping vibration attenuation vibrations.Oil through compression valve returns shoe cream room.Complete compression damping function.
During recoil of spring, the work of piston rod rising rebuilt valve is set up damping by gap and orifice restriction and is suppressed spring to be beated.Compression valve one-way valve opens, from shoe cream room makeup oil, terminates.
Three, " the active vibration damper of twin-tub " working principle:
1, form sealed environment by solenoid valve group inoculated vibration damper specific hydraulic fluid (because rebuilt valve and compression valve are one-way throttle valves) deaeration.Be pressurized to 5 kg/cm.
2, piston rod one pressurized rises to top, and movable piston pressurized moves.Because diameter 4mm spring is arranged at movable piston top, movable piston balances stopping with it to spring force.Close oil filler and reach standard vibration damper function,
Operation program is identical with foregoing standard vibration damper function.According to data.Automobile in the process of moving vibration frequency up to 30 hertz when there being 5 kg/cm pressure can meet high frequency fuel feeding demand in system.
3, when injecting 5 kg/cm with upward pressure in system, compression valve block produces back pressure with recovery valve block, and its physical property is changed, and damping becomes large.Along with injection pressure strengthens, compression increases with recovery damping.There is adjustment damping function.
4, according to formula radius X radius X3.14x kg/cm.
Known piston diameter 60mm pressure 30 kg/cm piston rod two climbing power reaches the rise of 800 kilograms of piston rods two.(meet and raise tare condition) has lifting function
5, devise during piston rod one mobile working, separately, filler opening is equipped with one-way valve (11) to oil inlet and outlet, electromagnetic valve component oil outlet two position two-way valve (13).Vibration damper internal fluid passages asphalt channel (5) external connecting pipe road (12) forms performance loop.
Receive signal when cornering, oil outlet two position two-way valve is closed.Because filler opening has closed check valve.Piston rod one is changed vibration damper function by locked, becomes the supporting element between wheel and vehicle body.The centrifugal force solved in turning process increases vehicle body and occurs centre-of gravity shift vehicle body rollover phenomenon.(key problem that this technological invention will solve).(being also the defect of vibration damper on market, the reason that traffic accident is occurred frequently) makes the creativeness reform of safety member vibration damper.
Therefore, the invention travelling comfort is good, curved performance is good excessively.Can be used for luxury car and SUV go-anywhere vehicle etc.
Four, apply: in order to make the invention market-oriented as early as possible, plain edition car is selected: 1, and the active vibration damper of twin-tub, 2. steering angle sensor, vehicle speed sensor combine.
Working principle: rotation direction sensor, vehicle speed sensor are signaled, two position two-way valve is closed.The locked vibration damper that makes of piston rod becomes supporting element.
Effect: standard vibration damper adds turning security.The market demand is high.Fabricating cost is low, facilitates market access.
