The concrete thing mode of implementing:
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
As shown in Figures 1 to 4, a kind of electrorheological fluid vibration damper of the present utility model, comprise piston rod 6 and the coaxial piston 1 that is fixed on its downside end, outer edge side coaxial rings at piston 1 is with inner cylinder tube 9, be covered with outer cylinder 13 at inner cylinder tube 9 outer rim covers, the top of inner cylinder tube 9 and outer cylinder 13 by guide holder 15 and oil sealing 14 with on the two coaxial piston rod 6 that is fixed on piston 1 top, its underpart and base 17 coaxial fixedlying connected, inwall lower end at inner cylinder tube 9 is embedded with supporting base 16, the outer rim of piston 1 is slided and is connected on the inwall of inner cylinder tube 9, piston 1 is the A chamber on top with inner cylinder tube 9 partitions, the B chamber of bottom, inner cylinder tube 9 cuts off by bottom support seat 16 and base 17 again the C chamber, inner cylinder tube 9 surrounds annular D chamber by the guide holder 15 on its top and the base 17 of bottom again with outer cylinder 13, on the end face of piston 1, be evenly equipped with four manholes 2 vertically, be axially arranged with two trapezoidal grooves in the internal face upper edge of manhole 2, trapezoidal groove is symmetrically distributed on the internal face of manhole 2, be inlaid in the trapezoidal groove with the insulating bush 3 of trapezoidal groove interworking, clamping has electrode 4 in insulating bush 3, clamping has arc positive electrode 41 in paracentral insulating bush 3, clamping has arc negative electrode 42 in the insulating bush 3 of the opposite side relative with it, on arc positive electrode 41 and arc negative electrode 42, radially be extended with integral type dividing plate 8, dividing plate 8 relatively equidistantly is interspersed on the internal face of through hole 2, place, axle center at piston rod 6 has metallic channel 7 vertically, in metallic channel 7, be embedded with lead 5, arc positive electrode 41 links to each other with power supply by lead 5, ground connection after arc negative electrode 42 and piston rod 6 conductings, compression valve 10 and recuperation valve 11 are housed on the supporting base 16 of inner cylinder tube 9 bottoms vertically, the coaxial dust-proof cover 12 that is fixed with in the upper end portion of piston rod 6, dust-proof cover 12 Open Side Down shroud is on outer cylinder 13 tops, upper end portion and piston rod 6 vertical weldings at piston rod 6 are connected to suspension ring 18, and base 17 downsides in the bottom are symmetrically welded with suspension ring 18.
During use, when wheel walks to the convex-concave road surface, wheel is when the vehicle body, and vibration damper is compressed, and piston 1 moves down, B chamber volume reducing, oil pressure raises, and flow through manhole 2 to the A chambeies at dividing plate 8 places that are interspersed of fluid are owing to have piston rod 6 in the A chamber, the volume that the volume that increases in the A chamber reduces less than the B chamber, part fluid promptly flow to laggard D chamber, C chamber by compression valve 10.Wheel is during away from vehicle body, vibration damper is stretched, this moment, damper piston 1 moved up, A chamber oil pressure raises, the flow through manhole 2 at dividing plate 8 places that are interspersed of fluid flows into the B chambeies, and same owing in the A chamber piston rod 6 is arranged, the fluid that is flowed into by the A chamber is not enough to replenish the volume that the B chamber is increased, produce certain degree of vacuum in the B chamber, the fluid in this moment D chamber is pushed recuperation valve 11 inflow B chambeies open and is replenished behind the C chamber.Under steam, can come automatically or the voltage on the manual tune electrode 4 according to the actual road conditions on road surface: when the voltage on the increase electrode 4, fluid stickiness in the through hole 2 increases thereupon, the fluid passing ability is poor, and it is big that the whole vibration damper damping becomes, when the voltage on the minimizing electrode 4, electric field in the through hole 2 dies down, the fluid stickiness of flowing through decreases, and passing ability is better, and the whole vibration damper damping diminishes.
Specific embodiment described herein only is that design of the present utility model is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
