The present invention can improve the ride comfort of automobile and handling stability and the needs to damping force, on good road surface
On, apply less electric current, it is thus achieved that good automobile ride, poor road surface increases electric current, reaches
To preferable damping property, when motor turning or braking, increase electric current, reduce automobile side inclination angle respectively
And the angle of pitch, it is achieved that to automobile gesture stability.In order to reach that automobile ride control and handling stability are controlled,
Magneto-rheological vibration damper must export enough damping forces, in order to export bigger absorber damping force, except knot
Structure size, magnetic rheological liquid model select and outside annular damper path clearance, are necessary for increasing coil arrangement
The number of turns, increase the controlled damp channel length of magnetic flow liquid.The present invention has and is mainly characterized by as follows: (1)
The present invention includes that annular damper passage and lower annular damper passage all can be by magnetic field controls so that controlled
The length of annular damper passage increases one times, it is possible to significantly promote the damping force of the present invention；(2) coil
Easily arranging, the vibroshock of same size, the present invention can increase the number of turns that coil is wound around, thus enhances
The magnetic field of annular damper passage, reaches to increase the purpose of damping force.It also avoid monotubular unicoil vibration damping simultaneously
The problem that device piston crown axial dimension is long, has fully ensured that the free travel of vibroshock, it is ensured that whole
The convenience installed on car.(3) owing to adding coil turn, while fully ensuring that damping force output,
Suitably damp channel gap can be increased, prevent magnetic flow liquid from blocking in annular damper passage, also avoid
There is the situation of sudden change in vibroshock inner magnet rheology hydraulic coupling, it is to avoid showing of deformity occurs in damping force curve
As, it is ensured that reasonably vibroshock external characteristics.
As shown in Figure 1, 2, 3, when the present invention is in stretching travel, piston 22 and piston rod 26 drive
The magnetic flow liquid of upper piston area flows up, and magnetic flow liquid clamp-ons the upper annular resistance of upper end under the effect of the pressure
In Buddhist nun's passage, being acted on by coil magnetic field at upper annular damper channel position, viscosity increases, flow resistance
Increase, after magnetic flow liquid flows through annular damper passage, enter in the cavity between inner core 9 and urceolus 6,
Then the cavity of resorption of piston 22 is flowed into by lower annular damper passage, equally in the lower annular damper passage of lower end
Also can be by the action of a magnetic field of coil, magnetic flow liquid viscosity increases, and flow resistance increases, electric current added by coil
The biggest, magnetic flow liquid is the biggest at resistance suffered by upper annular damper passage and lower annular damper passage, magnetic flow liquid
Absorber damping force is the biggest.When magneto-rheological vibration damper is in compression travel, magnetic flow liquid flowing is in opposite direction.
Such as Fig. 1, shown in 4, in stretching travel, the pull-out of piston rod 26 makes to vacate one inside vibroshock
Partial volume, this partial volume is promoted cylinder piston 12 by the high pressure nitrogen in cylinder block 11 so that nitrogen cylinder
Piston 12 lower end magnetic rheological liquid enters the lower cavity of piston 22 by annular damper passage under vibroshock.
In same compression travel, the magnetic flow liquid that piston rod accounts for enters nitrogen cylinder by lower end annular damper passage
Body piston.
