Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the present invention is further illustrated, but protection scope of the present invention is not limited to this.
As shown in Figure 1, upper hanger 1 is hinged with piston rod 20 upper end, loop coil permanent magnet 2 is fixed on piston rod 20 and is positioned at the inner side of described permanent magnet 22, and coil permanent magnet 2 is uniformly tied with densely covered first coil, and first coil is connected with outer terminal circuit with centering coil through hole 6 via coil throughbore 3.Permanent magnet 22 is fixed on inside magnetic suspension cylinder barrel 21 casing wall, and magnetic suspension working chamber about 4 two ends are provided with buffer stopper 23 and lower buffer stopper 5.Magnetic suspension cylinder barrel 21 is fixing with oil storage cylinder barrel 19 to be connected, and contains magnetic flow liquid 10 in oil storage cylinder barrel 19 and work cylinder barrel 16.Piston rod 20 lower end is connected with electromagnetic piston 17, and electromagnetic piston 17 is provided with rebound valve 8 and flowing valve 18, and magnet exciting coil 7 is arranged on electromagnetic piston 17 through pre-load nut 9 pretension, and the second coil on described magnet exciting coil is connected with outer terminal circuit through centering coil through hole 6.Damping piston 12 is provided with compression valve 11 and recuperation valve 15, and work cylinder barrel 16 is hinged with oil storage cylinder barrel 19 lower end, and work cylinder barrel 16 lower end offers through hole 14, it is achieved the fluid circulation between work cylinder barrel 16 and oil storage cylinder barrel 19.Lower hanger 13 is hinged with oil storage cylinder barrel 19.
Upper hanger 1 is connected with vehicle body, and lower hanger 13 is connected with wheel, thus completes the installation of a kind of multi-state vehicle suspension.
Anti-vibration performance demand according to running car, suspension can be operated under " passively ", " half actively ", " actively " three kinds of operating modes.
When all not passing to electric current in coil permanent magnet 2 with magnet exciting coil 7, now suspension work is under " passively " operating mode.Rely on the mutual attractive force bearing vehicle body weight between permanent magnet 22 and coil permanent magnet 2 synonyms pole.When suspension is subject to road roughness impact, producing relative displacement between permanent magnet 22 and coil permanent magnet 2, graviational interaction makes it have the trend returning to equipoise.Cause that suspension loses effective travel for avoiding being subject to shock loading, upper buffer stopper 23 lower end plane and on lower buffer stopper 5 transverse plane be between the coil permanent magnet 2 being not powered on and permanent magnet 22 synonyms pole the extreme position of greatest attraction forces.Magnetic flow liquid 10 produces damping force effect by rebound valve 8, flowing valve 18, compression valve 11 and recuperation valve 15.Without outer energy input under this operating mode, suspension property is general.
When passing to electric current in only coil permanent magnet 2, now suspension work is under rigidity adjustable " half actively " operating mode.By changing size of current and direction, it is achieved the change of mutual attractive force between permanent magnet 22 and coil permanent magnet 2 synonyms pole, it is achieved the rigidity of magnetic suspension spring is adjustable.When passing to electric current in only magnet exciting coil 7, now suspension work is under damping adjustable " half actively " operating mode.Changing size of current and direction, changing magnetic induction around, thus changing the viscosity characteristics of magnetic flow liquid 10, it is achieved damp adjustable.Needing outside energy to input under this operating mode, suspension property is more excellent.
When the coil in coil permanent magnet 2 with magnet exciting coil 7 all passes to electric current, now suspension work is under " actively " operating mode.When needs suspension provides greater stiffness, change the electric current in coil permanent magnet 2 coil, it is made to produce and coil permanent magnet 2 magnetic field in the same direction, captivation between synonyms pole just increases, according to formula F=kx, when shift invariant, the increase of elastic force is the increase due to spring rate, and namely now the rigidity of suspension becomes big.When needs suspension provides less rigidity, changing the electric current in coil permanent magnet 2 coil so that it is producing the magnetic field reverse with coil permanent magnet 2, the captivation between synonyms pole just reduces, and in like manner can obtain, the rigidity of magnetic suspension suspension reduces.The rigidity realizing suspension with this is controlled.Change the electric current in magnet exciting coil 7, thus changing the magnetic induction of magnet exciting coil 7 surrounding magnetic field so that magnetic flow liquid 10 viscosity characteristics changes, it is achieved damp controlled.Carry out the combine regulation of suspension rate and damping according to road condition, obtain good anti-vibration performance.Needing extraneous higher-energy input under this operating mode, suspension property is optimum.
When multi-state vehicle suspension is operated in " passively " or damps under adjustable " half actively " operating mode, road roughness impacts and drives upper hanger 1 and lower hanger 13 relative motion, relative displacement is produced so that coil permanent magnet 2 coil produces faradic current between coil permanent magnet 2 and permanent magnet 22.This portion of electrical current can being reclaimed by outer terminal circuit, now suspension work is under " accumulation of energy " operating mode, it may be achieved the recovery of vibrational energy is stored, in order to follow-up use, is greatly reduced energy expenditure.
Described embodiment be the present invention preferred embodiment; but the present invention is not limited to above-mentioned embodiment; when without departing substantially from the flesh and blood of the present invention, those skilled in the art can make any conspicuously improved, replace or modification belongs to protection scope of the present invention.
