Detailed description of the invention
In order to be more clearly understood from technical characteristic, purpose and the effect of invention, now the comparison accompanying drawing explanation present invention's is concrete
Embodiment, the most identical label represents same or analogous part.Accompanying drawing is merely to illustrate the present invention, does not represent this
The practical structures of invention and actual proportions.
Fig. 1 show a kind of embodiment of magnetic flow liquid damping-adjustable shock-absorber of the present invention, including cylinder barrel 10, upper end cover
3, piston rod 1, piston 5, diaphragm 7, bottom end cover 9, external oil circuit and damping regulation valve.
Described cylinder barrel 10 is hollow cylinder, and two ends are sealed by upper end cover 3 and bottom end cover 9 respectively, and described piston rod 1 passes
Upper end cover 3 is connected with piston 5, is provided with lining and oil sealing 2 between described piston rod 1 and upper end cover 3.The one of described cylinder barrel 10
Holding by piston rod 1 and external connection, the other end is by the circular connecting hole 17 processed on bottom end cover 9 and external connection.
Described cylinder barrel 10 is internal is divided into recovery chamber 4, compression chamber 6 and nitrogen chamber 8 the most successively by piston 5 and diaphragm 7;
It is filled with magnetic flow liquid in described recovery chamber 4 and compression chamber 6, in described nitrogen chamber 8, is filled with high pressure nitrogen.Described damping regulation valve
Being arranged on the outside of cylinder barrel 10, described external oil circuit includes external oil circuit a12 and external oil circuit b15, one end of damping regulation valve
Being connected by external oil circuit a12 and the hydraulic fluid port a11 restoring chamber 4, the other end is by the hydraulic fluid port of external oil circuit b15 with compression chamber 6
B16 connects;It is outside that described damping regulation valve is arranged on cylinder barrel 10, and corresponding piston 5 impulse stroke length, i.e. piston 5 is at hydraulic fluid port
Activity between a11 and hydraulic fluid port b16;Coil is full of in described damping regulation valve outer ring, and described coil electricity produces magnetic field, according to resistance
Buddhist nun regulates valve internal actual oil circuit layout and optimizes Distribution of Magnetic Field, to increase output damping force;Can by changing coil canoe
To change magnetic field space distribution, change magnetic field size by changing wire circle, magnetic can be changed by changing current strength in coil
Field intensity, magnetic field intensity changes, then the magnetic flow liquid viscosity being in magnetic field changes, and then regulation magnetic flow liquid leads to
The damping force produced during overdamp regulation valve internal oil passages, changes magnetic flow liquid circulation speed, thus limits piston 5 movement velocity.
Described damping regulation valve internal oil passages diameter is less, and length is relatively long, plays the effect of elongated damping hole.Preferably,
Described damping regulation valve internal oil passages a diameter of 1~3mm, is equivalent to the elongated damping hole of common shock absorber, plays generation damping force
Effect.Described damping regulation valve internal oil passages can be arranged voluntarily according to working condition requirement, to be made by magnetic field in changing damping regulation valve
Oil circuit length, the requirement of space magnetic field can be arranged by described coil canoe according to actual condition, Fig. 1 and Fig. 2 institute
Being shown as two kinds of oil circuit arrangements of described damping regulation valve and state two kinds of canoes of coil, wherein described in Fig. 1, damping is adjusted
Joint valve is damping regulation valve a13, and it is coil a14 that coil is full of in described damping regulation valve a13 outer ring, the magnetic field that coil a14 produces
Vertically through damping regulation valve a13, described coil a14 magnetic direction and described damping regulation valve a13 internal oil passages side
To parallel, now magnetic field is less to magnetic flow liquid viscosity influence.The valve of damping regulation described in Fig. 2 is damping regulation valve b18,
The coil that damping regulation valve b18 outer ring is full of is coil b19, and the magnetic field that coil b19 produces horizontally passes through damping regulation
Valve b18, described coil b19 magnetic direction is perpendicular with described damping regulation valve b18 internal oil passages direction, and now magnetic field is to magnetic
The impact of rheology fluid viscosity is bigger.So can arranging according to the damping internal actual oil circuit of regulation valve and optimizing Distribution of Magnetic Field, defeated to increase
Go out damping force.From Fig. 1 and Fig. 2, in Fig. 2, in damping regulation valve b18, oil circuit length is significantly greater than in Fig. 1 damping regulation
Oil circuit length in valve a13, when to damping regulation valve regulation area requirement little and to regulation required precision higher time use Fig. 1 institute
The embodiment shown, when require damping regulation valve regulation scope relatively big and to regulation required precision the highest time use the reality shown in Fig. 2
Execute mode.The longest by the oil circuit of magnetic fields, then damp adjustable range is the biggest, and degree of regulation is the lowest, otherwise then damps regulation
Range shorter, degree of regulation improves.
The course of work of the present invention:
Compression stage, piston rod 1 promotes piston 5 descending, and compression chamber 6 pressure rises, and compression chamber 6 produces pressure with restoring chamber 4
Difference, compression chamber 6 magnetic flow liquid enters damping regulation valve by external oil circuit b15, then flows into from external oil circuit a12 and restore chamber
4.Owing in compression chamber 6, pressure increases, diaphragm is pressed for 7 times, the further supercharging of nitrogen chamber 8 mesohigh nitrogen, nitrogen chamber 8 accumulation of energy,
Serve absorption impact, reduce the effect of vibrations.
Stabilization sub stage, pressure produced by the pressure of piston 5 equal to restoring chamber 4 pressure, is pressed by piston rod 1 equal to compression chamber 6
By force, equal to nitrogen chamber 8 internal pressure, piston rod 1 is equal to pressure plus restoring chamber 4 to the pressure of piston 5 to the pressure of piston 5
The contracting chamber 6 pressure to piston 5, compression chamber 6 to the pressure of diaphragm 7 equal to nitrogen chamber 8 internal high pressure nitrogen to diaphragm 7 pressure,
The most whole damper reaches balance.
Recovery phase, the pressure of piston 5 is reduced by piston rod 1, and in compression chamber 6, magnetic flow liquid promotes piston 5 up, restores
Chamber 4 pressure increases, and restores chamber 4 and produces pressure reduction with compression chamber 6, and magnetic flow liquid is from restoring chamber 4 through external oil circuit a12, damping
Regulation valve and external oil circuit b15 flow into compression chamber 6, and in the process, compression chamber 6 pressure reduces with pressure in nitrogen chamber 8,
Nitrogen chamber 8 releases energy, and helps damper to restore.
Owing to damping regulation valve internal oil passages diameter is less, length is relatively long, plays the effect of elongated damping hole, magnetic flow liquid
During by damping regulation valve, producing damping force, this damping force is directly proportional to fluid passage rate, thus limits fluid circulation speed
Degree, further, limits piston 5 downlink and uplink speed, serves the effect of bumper and absorbing shock.
Described damping regulation valve is arranged on outside damper cylinder barrel, by external oil circuit, magnetic flow liquid is drawn out to damping and regulates valve,
Damping regulation valve outsourcing has coil, regulates the magnetic flow liquid viscosity through overdamp regulation valve by changing coil current size, from
And change damper output damping force.The present invention is placed in outside cylinder barrel by damping regulation valve, it is simple to dispel the heat during work, the most just
In I&M;Coil is external, installs simple, and convenient heat radiation is without regard to sealing problem;In damping joint valve, oil circuit can basis
Actual requirement is arranged, changes damp adjustable range by changing damping oil circuit length.The present invention is realizing the adjustable basis of damping
On, original shock absorber structure to be changed less, processing I&M difficulty is relatively low, and achieves the continuously adjustabe of damping.
