(5) though the external o is easy to coiling, but o directly contacts with the electromagnetic current fluid, thereby o is among the electromagnetic current fluid pressure field of alternation, simultaneously the also energising of intractable o and sealing problem for mesohigh electromagnetic current fluid;
(6) be bordering in the prior art of this electromagnetic current fluid piston assembly structure, cavity wall does not have magnetic shield in the o, thereby leakage field is serious, when the volume fraction of soft magnet powder is big in the electromagnetic current fluid especially
So;
(7) be similar in the prior art of this electromagnetic current fluid piston assembly structure, shunt the location, through-flow and that a collecting type structure makes the magnet case baffle plate of handling the o inner chamber every the magnetic difficulty.
Task of the present invention provides that o coiling cost is low, o separates with the electromagnetic current fluid, less than magneto-rheological fluid leakproof under 140 barometric pressure, the minimizing of o leakage field, fluid passage and every magnetic simple more and easily, reliability enhancing, long service life, processing and the cheap a kind of single-stage electromagnetic current fluid damper of assembly cost, to adapt to requirement of mass production.
For solving above-mentioned task, solution of the present invention is: design a kind of single-stage electromagnetic current fluid damper.This single-stage electromagnetic current fluid damper is made up of last magnet case (30), following magnet case (160), o (80) and connecting body (10), Sealing I (40), Sealing II (100); It is characterized in that: magnetic shield (50) serves as the skeleton of o (80); O (80) and magnetic shield (50) are arranged in magnet case (30) and the formed annular space of following magnet case (160); Last magnet case pole parts (180) and following magnet case pole parts (170) lay respectively at the inner chamber of o (80) and magnetic shield (50); Last magnet case (30) is provided with passage (20) and passage (60); Following magnet case (160) is provided with passage (90); Be provided with pole parts (180) on the last magnet case; Be provided with pole parts (170) on the following magnet case; Between the pole parts (170) of the pole parts (180) of last magnet case and following magnet case, formed an annular magnetic gap runner (70); Magnetic shield (50) with o (80), go up the pole parts (180) of magnet case, the pole parts (170) of magnet case is every magnetic down.
Described single-stage electromagnetic current fluid damper is characterized by series connection connection mutually between each runner (20,60,70,90), and this channels in series is the central core of circulation that the electromagnetic current fluid flows.
Advantage of the present invention is:
(1) o adopts outer formula coiling, thus fairly simple, cost is low;
(2) adopt structural design and necessary Sealing, o is separated with the electromagnetic current fluid, avoided the polishing action of electromagnetic current fluid for the o lead;
(3) o separates with the electromagnetic current fluid, thereby avoided o to be among the electromagnetic current fluid alternating pressure field, be easy to handle the energising of o with for sealing, leakproof problem less than 140 atmospheric mesohigh electromagnetic current fluids;
(4) cavity wall is provided with magnetic shield in the o, and leakage field is reduced;
(5) each components and parts is that separated superposition formula connects, thereby has reduced processing and assembly cost, helps producing in enormous quantities.
(6) in this single-stage electromagnetic current fluid damper structure, owing to adopted afflux one shunting structure, thereby the fluid passage of handling the o inner chamber is provided with and simple more and easily every magnetic;
(7) comprehensive above advantage prolongs cost reduction, reliability enhancing, the working life of single-stage electromagnetic current fluid damper.
