As shown in Figure 1, Figure 2, Figure 3 shows, antivibrator, MR valve and accumulator connect to form closed-loop path by hydraulic tube.
When piston rod (21) is moved in antivibrator, the magnetic flow liquid flowing in antivibrator cylinder body (19) is oppressed.Magnetic flow liquid flows through magnetic
Rheology valve, is passed through a certain size electric current to magnet exciting coil in MR valve (6), due to magnetic conduction disk (4), valve body (3) and valve
Core (7) is No. 10 steel permeability magnetic materials, because the magnetic line of force that galvanomagnetic-effect is formed passes through magnetic conduction disk (4), valve body (3) and valve element (7)
Form closed-loop path.The axial fluid course that the magnetic line of force had both been formed perpendicular to magnetic conduction disk (4) and valve body (3), and perpendicular to leading
The radial flow of liquid passage that magnetic disk (4), valve body (3) are surrounded with valve element (7).When magnet exciting coil (6) is powered, due to the action of a magnetic field,
Magnetic flow liquid at radial and axial fluid course its viscosity can increase, and yield stress strengthens.Magnetic flow liquid flows through the two and leads to
Road, just must pull against the intermolecular power of this catenation, so as to cause magnetic flow liquid to flow through the resistance increase of valve, can slow down
Or the flowing of prevention liquid, so as to produce pressure differential.By adjusting size of current in magnet exciting coil (6), magnetic flow liquid can be changed
Yield stress, it is poor with the inlet and outlet pressure needed for reaching, and then the pressure of the interior left chamber of change antivibrator cylinder body (19) and right chamber
Difference, reaches the purpose for adjusting output damping force.
