Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described, but protection domain of the present utility model is not limited to this.
As shown in Figure 1, upper hanger 1 is hinged with piston rod 20 upper end, toroid winding permanent magnet 2 to be fixed on piston rod 20 and to be positioned at the inner side of described permanent magnet 22, coil permanent magnet 2 is evenly tied with densely covered first coil, the 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 epitrochoidal chamber about 4 two ends are provided with bump rubber 23 and lower bump rubber 5.Magnetic suspension cylinder barrel 21 is fixedly connected with oil storage cylinder barrel 19, 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, electromagnetic piston 17 is provided with rebound valve 8 and flowing valve 18, excitation coil 7 is arranged on electromagnetic piston 17 through pre-load nut 9 pretension, and the second coil on described excitation coil is connected with outer terminal circuit through centering coil through hole 6.Damping piston 12 is provided with compression valve 11 and throttle compensating 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, and the fluid realized between work cylinder barrel 16 and oil storage cylinder barrel 19 circulates.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, completes a kind of installation of multi-state vehicle suspension thus.
According to the anti-vibration performance demand of running car, under suspension can be operated in " passive ", " half initiatively ", " initiatively " three kinds of operating modes.
When all not passing to electric current in coil permanent magnet 2 with excitation coil 7, now suspension work is under " passive " 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 be subject to road roughness impact time, produce relative displacement between permanent magnet 22 and coil permanent magnet 2, graviational interaction makes it have to return the trend of equipoise.Cause suspension to lose effective travel for avoiding being subject to impact load, on upper bump rubber 23 lower end plane and lower bump rubber 5, transverse plane is the end position of greatest attraction forces between coil permanent magnet 2 and permanent magnet 22 synonyms pole be not energized.Magnetic flow liquid 10 produces dumping force effect by rebound valve 8, flowing valve 18, compression valve 11 and throttle compensating valve 15.Without the need to outer energy input under this operating mode, suspension property is general.
