Description
The utility model relates to the magnetic rheological liquid applied technical field.
Along with vying each other of express highway, traffic facilities development such as speed-raising railway etc. and passenger transport market, for satisfying quick, safe, the comfortable needs of passenger, the road speed of vehicle (no matter being automobile or rolling stock) improves constantly.But some circuits are owing to the restriction of conditions such as landform, and the radius of curve of circuit can't be amplified, and vehicle also must adapt to different road conditionss simultaneously.Therefore more and more come into one's own by the active that improves the vehicle suspension system parameter, the research of half active control technology, especially half ACTIVE CONTROL, adopt the shock absorber that becomes damping, adjust dumping force by real-time control, to adapt to the variation of condition of service such as road, vehicle, guarantee good driving comfort.Except number switch valve, electromagnetic damper, the change damping shock absorber that number adopts emr fluid of working as of development potentiality is arranged most in the adaptive damping device, it regulates the damping size by change electric field, magnetic field, responds (ms level), control soon accurately.Magnetic rheological liquid (MR Fluids based on magnetic rheology effect, claim intellectual material, metal nanometer material again) and the application of device in vehicle hanging half ACTIVE CONTROL, electrorheological fluid, magnetic flow liquid and electricity-magnetic flow liquid are based on electric rheological effect (ERE) and magnetic rheology effect (MRE) and the suspending fluid made, the new material of its viscosity be can under electric field, magnetic field or electricity-magnetic field effect, change respectively rapidly, intellectual material or intelligent liquid are called as.Wherein electric rheological effect was just found by American Wills Winslow as far back as nineteen forty-seven, but just come into one's own and make progress until the beginning of the eighties, at present, many in the world countries such as American and Britain, day, moral, method comprise that China is all in the research of carrying out this field.Begin to progress into applied research electrorheological fluid and device technology to the beginning of the nineties, for example change the viscosity of electrorheological fluid, make power-transfer clutch, shock absorber etc. thus and be applied to automotive field by the control electric field intensity.Owing to need high voltage electric field, cause to use to be restricted, thereby, magnetic rheology effect and magnetic flow liquid because do not have that Keep Clear-High Voltage, rheological effect is higher than electric current and becomes and come into one's own in the early 1990s, simultaneously, the electricity-magnetic rheology effect of electromagnetic field combined action or alternating action and rheology liquid also are suggested.The domestic and international at present mechanism to electricity, magnetic flow liquid, rheological effect has solved most of problem, but the settlement issues of the suspended particles of magnetic flow liquid does not also solve well, and this problem will solve fully on the mechanism and need the regular hour, so applied research is made slow progress.If can solve the stability problem of rheology liquid, so just can under the situation that does not rely on mechanism research, realize the practical application of magneto-rheological vibration damper from device architecture.
The purpose of this utility model provides a kind of adaptive transmission control, and it solves in the shock absorber working process settlement issues of particulate in the magnetic flow liquid effectively.
The purpose of this utility model can be realized by following technical scheme; Adaptive transmission control, adopt most of structure of conventional shock absorber to comprise the store oil cylinder barrel and place the interior piston body of store oil cylinder barrel, piston body is located at the bottom of piston rod, piston body and store oil inner wall of cylinder cooperation place are provided with seal ring, store oil cylinder barrel bottom end cover is provided with installation ring, a through hole is stamped in the upper end, piston rod places this through hole by seal ring, the piston rod that is provided with fairlead passes piston body and affixed, piston body radially is provided with through hole, be provided with iron core and coil at piston body near the through hole place, the lead of described coil is drawn the store oil cylinder barrel by the fairlead of piston rod.Before shock absorber work and work initial, fitting piston moves and attracts and discharge solia particle one soft magnet powder particle in the magnetic flow liquid successively.When shock absorber was not worked, electromagnet energising was adsorbed on the magnetic of deposition around the magnetic pole with the strongest suction, and outage subsequently discharges, and magnetic slowly comes off, energising once more behind the certain hour, and repeated several times makes magnetic in the uniform substantially suspension of cavity of resorption; When the shock absorber disturbance is worked, can adopt at piston and run to the following time energising absorption of interposition, when balance position is above, discharge; Also can adopt, adsorb along with reciprocating motion of the pistons and discharge with certain switching frequency; Particulate about can making after some circulations in two chambeies evenly is suspended in the liquid.Adopt the special piston body of magnetic flow liquid design of domestic prior art level, piston body radially be provided with through hole and within it portion be provided with main magnetic field, can change magnetic flow liquid when making its restriction, work of electromagnet and pass through the speed of restriction so that realize adjustable damping with main magnetic field control, this shock absorber core technology is to adopt the electromagnetic distu mode to make its rectangular distribution in liquid to the precipitation magnetic, adopt this technology can adopt the magnetic flow liquid of general quality, the whole vibration damper cost is reduced greatly.Main magnetic field control part and control desk are done together, beyond damper structure.Wish finally to promote in following field: half ACTIVE CONTROL of vehicles such as automobile and railway hangs; The self adaptation vibration isolation of automobile, transport vehicle, fixed equipment support of engine; The vibration isolation and the vibration damping of construction machinery and equipment, heavy motor vehicle, trainman's seat; Novel hydraulic spares such as high-speed hydraulic valve.
Effect of the present utility model and advantage are to adopt the direct solenoid iron construction, with control of fixed frequency switch or position detection control, realize absorption and release to particulate; Have characteristics such as simple in structurely be easy to realize, control is simple and convenient, reliability is high, effective cost is low, can be used for the vibration isolation and the vibration damping of self adaptation vibration isolator, driver's chair and the operator's compartment of change damping shock absorber, support of engine in the suspension of vehicle half ACTIVE CONTROL.
