A split type structure is adopted for the air sac compensation split type magneto-rheological fluid seat damping absorber, a damping cylinder body and an excitation unit are separately placed, then the excitation unit can be freely placed and designed, and even a plurality of excitation units can be connected in series so that higher damping force can be obtained. The air sac compensation split type magneto-rheological fluid seat damping absorber comprises a hydraulic cylinder 1, a compensating air sac 2, a lower installation hole 3, a connecting pipe 4, an externally-arranged excitation unit 5, an upper installation hole 6, the piston rod 7, a piston 8 and the like.
Description
Technical field
The utility model relates to a kind of air bag and compensates split type magnetic flow liquid seat damping shock absorber, be specifically related to adopt magnetorheological damping cylinder body and excitation unit split-type structural, use magnetic flow liquid as working medium, use withstand voltage, oil resistant air bag magnetic flow liquid seat damping shock absorber by way of compensation, belong to the damping vibration attenuation technical field.
Background technique
Magnetic flow liquid be a kind of by strong magnetism solid superfine particle evenly spread to form in the carrier fluid the solid-liquid stable suspersion liquid system of mixing mutually, it not only has the flowability of liquid but also have the strong magnetism of solid ferrormagnetic substance.Because being shear yield strength and the magnetic intensity after moment, reversible and its rheology, the rheology of magnetic flow liquid under magnetic field effect have stable corresponding relation, be a kind of intelligent controlled fluid material of function admirable, be widely used in novel damping shock absorber field.Magnetic flow liquid seat damping shock absorber adopts integrative-structure more at present, and namely the excitation unit unites two into one with piston.Though this structure is succinct, the design of magnetic circuit and runner is subjected to the restriction in space, and manufacture cost is higher.The compensation of piston rod idle running is gone up and is all adopted the mode of compensation cylinder to carry out usually, the compensation cylinder can provide very high gas pressure, can reach 2MPa usually, the damper rod motion that in time compensating line speed is very high, but there is processed complex equally, takies drawbacks such as larger volume simultaneously.Consider that the common linear velocity of seat damping shock absorber is very low, load simultaneously is less situation again, adopts the compensation air bag to replace the compensation cylinder, simplifying technology, reduces under the situation of volume, also can satisfy the piston rod idle running compensation under the low load of low speed.
Summary of the invention
It is simple that the purpose of this utility model provides a kind of processing, and the air bag that can satisfy the piston rod idle running compensation under the low load of low speed simultaneously again compensates split type magnetic flow liquid seat damping shock absorber.Air bag compensates split type magnetic flow liquid seat damping shock absorber and adopts split-type structural, and resistance cylinders and excitation unit are placed apart, can compare like this and freely place and design the excitation unit, even a plurality of excitations unit of can connecting is to obtain higher damping force.
The technical solution that realizes above-mentioned purpose is as follows:
A kind of air bag compensates split type magnetic flow liquid seat damping shock absorber, comprise oil hydraulic cylinder, external excitation unit and compensation air bag, described oil hydraulic cylinder and external excitation unit adopt the split-type design split to place, described compensation air bag is fixed on the bottom of hydraulic cylinder body inside, compensates as the piston rod idle running.Described split type magnetic flow liquid seat damping shock absorber also comprises following mounting hole, connecting tube, goes up mounting hole, piston rod and piston; Wherein, piston is positioned in the oil hydraulic cylinder, is connecting piston rod.
Further, be full of the working medium magnetic flow liquid in the described oil hydraulic cylinder, material aluminium or stainless steel non-magnet material are made.
Further, described compensation air bag material selects for use ethylene-propylene acetoacetic ester (EEA) to make; Be full of certain pressure gas in the described compensation air bag, select nitrogen or argon gas usually for use, the volume differences that moves up and down and cause in order to compensating piston.
Further, described connecting tube is joined together to form the working medium loop with external excitation unit and oil hydraulic cylinder.Described mounting hole down and last mounting hole are in order to be mounted on split type magnetic flow liquid seat damping shock absorber on the seat.
Preferably, described external excitation unit is a plurality of series connection.
The utility model compared with prior art has following distinguishing feature and good effect: one, and vibration damper cylinder body and excitation unit adopt split-type structural, can freely design the size of excitation unit; They are two years old; The compensation air bag is placed on hydraulic cylinder body inside, can obtain bigger free travel; Its three, adopt the compensation air bag as the idle running compensation of mesolow pressure range, manufacturing process is easy.
