Background technique
Magnetic rheological valve is compared with the conventional hydraulic control valve, and magnetic rheological valve is controlled flow by the magnetic flow liquid of valve by the size of control field coil electric current, does not have the mechanical part that moves, with respect to traditional mechanical valve, the magnetic flow liquid control valve has simple in structurely, and volume is little, be easy to control, speed of response is fast, and operational noise is low, and is wear-resistant, the reliability height, low cost and other advantages.Magnetic rheological valve is existing to be widely used.
The hydraulic control scope of magnetic rheological valve has the qualifications of itself.The flow direction of first magneto-rheological fluid in the magnetic gap space must be vertical with the direction in magnetic field; Next is the liquid chunnel of magneto-rheological fluid in the magnetic gap space.Under given boundary dimension, energy consumption, response time and given magneto-rheological fluid prerequisite, can obtain High Pressure Difference by following approach: the first is pressed the magnetic saturation intensity size of magneto-rheological fluid, place magnetic intensity maximum and be not more than the magnetic gap space of magneto-rheological fluid magnetic saturation intensity magneto-rheological fluid, make the magnetic rheology effect maximum that is produced; It two is to improve the flow channel length of magneto-rheological fluid in the magnetic gap space.In the actual design,, very difficult when realizing above two kinds of approach simultaneously because described magnetic gap space is limited.
The pressure reduction that how to improve magnetic rheological valve enlarges the hydraulic control scope of magnetic rheological valve, is the technical problem that the industry needs to be resolved hurrily.
For solving the problems of the technologies described above, Chinese patent discloses in the passage of a plurality of magneto-rheological fluids at magnetic rheological valve, the damping device (as the damp channel of damping piston, damped cylinder, damping coil control and damper etc.) of magnetic flow liquid is set, a kind of magnetic rheological valve structure is disclosed as Chinese patent, it is to form disc liquid flowing resistance passage between magnetic conduction disk and this end face, form annular liquid flowing resistance passage between the outer ring surface of magnetic conduction disk and the cylinder barrel again, be communicated with by the center hole of disc liquid flowing resistance passage, form a complete liquid chunnel with profit in-core portion.Structure although it is so can be provided with two groups or more satisfying the requirement of pressure, flow, but such structure do not utilize coil magnetic field fully and can strengthen the volume of valve, increases magnetic rheological valve assembling difficulty, rate of fault.
Summary of the invention
In order to overcome in the prior art, for increasing the damping device of the magnetic flow liquid that the magneto-rheological fluid channel resistance is provided with in the magnetic rheological valve, complex structure, increase the magnetic rheological valve volume, increase the technical deficiency of the rate of fault of magnetic rheological valve, the present invention proposes a kind of magnetic rheological valve structure of spiral liquid flow passage, magneto-rheological fluid is flowed along the liquid chunnel non-rectilinear, thereby extended the path length that the electromagnetic current fluid flows, improved utilization ratio for the limited magnetic line of force, under magnetic gap size permanence condition, improve the size of the controlled fluid pressure reduction of electromagnetic current fluid under the equal electric current [strength, reach energy-conservation and reduce the purpose of magnetic rheological valve equidimension.
The present invention realizes that the technological scheme one that goal of the invention adopts is, a kind of magnetic rheological valve of spiral liquid flow passage, comprise: valve body, coil brace, field coil, positioning disk and magnetic conductive disk, field coil is wrapped on the coil brace, magnetic conductive disk is arranged on the two ends of coil brace, positioning disk and magnetic conductive disk coaxial line are installed, form liquid chunnel between the corresponding end face of positioning disk and magnetic conductive disk, on the corresponding end face of described positioning disk and magnetic conductive disk, one group of block arc is set, and block arc forms spiral yarn shaped liquid chunnel on the end face of positioning disk.
On the corresponding end face of positioning disk and magnetic conductive disk, one group of pin is set, the block arc via pins is connected with the positioning disk end face.Described block arc is every the magnetic metallic material, and the arc curvature on the block arc is corresponding with the curvature of spiral yarn shaped liquid chunnel.Described positioning disk diameter greater than the circumference that block arc is set on, one group of pod apertures is set.
The invention has the beneficial effects as follows that magnetic rheological valve is simple in structure, make easy for installationly, do not increase the magnetic rheological valve volume, enlarge the control range of magnetic rheological valve.Structure of the present invention places magnetic intensity big and be not more than the magnetic gap space of magneto-rheological fluid magnetic saturation intensity magneto-rheological fluid, makes the magnetic rheology effect maximum that is produced; In limited magnetic gap space, improved the flow channel length of magneto-rheological fluid simultaneously; When having made full use of poly-magnetic cross section limited in the magnetic field, utilizing can also further poly-magnetic every the magnetic pressure circle; Require to significantly improve the pressure reduction of magneto-rheological fluid under the prerequisite at equal magneto-rheological fluid and traffic requirement, comparable size requirement, equal response time requirement, equal energy consumption.
