The operation principle of Electromagnetic Control arm used for electric vehicle is as follows:
Fluid resonant in damping hole 29 can produce Tuned mass damper effect, by change electromagnetism lining working chamber 27 in and liquid storage cylinder 26,28 in magnetorheological fluid performance, realize controlling magnetic flow liquid velocity of liquid assets in damping hole 29, it is not completely filled with magnetic flow liquid in liquid storage cylinder 26,28, there is also a part of nitrogen, make liquid storage cylinder there is compressibility.
When electromagnetism lining is static, working chamber 27, liquid storage cylinder 26,28 internal volume will not change, in three cavity volumes, pressure is equal, the magnetic flow liquid of each intracavity presents low viscous Newtonian fluid characteristic under zero magnetic field condition, working chamber 27 macroscopically will not difference flow with the magnetic flow liquid in liquid storage cylinder 26,28, and the performance now of electromagnetism lining is similar to tradition rubber bushing or hydraulic bushing characteristic.
Electromagnetism lining performance motion mode according to Fig. 8, when electromagnetism lining moves in X-direction, working chamber 27, liquid storage cylinder 26,28 volume now diminish, magnetic flow liquid in working chamber 27 flows to the liquid storage cylinder 26,28 of both sides respectively by damping hole 29, the mechanical energy of X-direction can be converted to heat and distribute during flowing through damping hole 29.As shown in Figure 5, 20 are passed through when there being electric current, 21, 22, 23, 24, during 25 outside line, owing to there is loop circuit in bottom, i.e. at working chamber 27 and liquid storage cylinder 26, corresponding magnetic field is produced in 28 spaces, magnetic flow liquid can change the viscosity of fluid according to the power in magnetic field, when working chamber 27 and liquid storage cylinder 26, during 28 internal magnetic field difference, working chamber 27 and liquid storage cylinder 26, in 28, the viscosity of magnetic flow liquid also can there are differences, and now flowed into liquid storage cylinder 26 by working chamber 27 by damping hole, magnetic flow liquid in 28 can be different in same external conditional stimulus down-off, also respective change can be there is in the damped coefficient produced in electromagnetism bush inside.By adjusting the outside size being passed through electric current, it is achieved the control to electromagnetism bush inside magnetic field intensity, then affect magnetorheological fluid performance, it is achieved electromagnetism lining mechanical property in the X direction.When the power in X-direction big the most to a certain extent time, rubber inner core inner tube can be fitted with rubber limited block 30, it is achieved controls the maximum of power in X-direction.
Electromagnetism lining performance motion mode according to Fig. 8, when electromagnetism lining moves in the Y direction, now working chamber 27, the volume of liquid storage cylinder 26,28 can reduce therewith, and there is gas in liquid storage cylinder 26,28 inside, there is compressibility, when working chamber 27 volume reduces, magnetic flow liquid can be by damping, 29 flow in liquid storage cylinder 26,28, control principle is identical when moving with X-direction, changes size of current, controls magnetic field intensity, thus control magnetic flow liquid viscosity, then adjust electromagnetism lining mechanical property in the Y direction.
Electromagnetism lining performance motion mode according to Fig. 8, when electromagnetism lining moves in γ direction, mainly both sides liquid storage cylinder 26, 28 work, when electromagnetism lining inner core 4 side is raised, when opposite side reduces, liquid storage cylinder 26 volume diminishes, liquid storage cylinder 28 volume increases accordingly, flowing relatively is done by damping hole 29 at two intracavity magnetic flow liquids, by changing input current size, the final viscosity controlling each intracavity magnetic flow liquid, and, when magnetic field intensity increases, the cutting performance meeting respective change of magnetic flow liquid, by both the above controlling factors electromagnetism lining mechanical property on γ direction.
According to the electromagnetism lining performance motion mode of Fig. 8, when electromagnetism lining moves in θ direction, rubber inner core 3, by shear action, can undertake a part of moment of torsion.As it is shown in figure 5, working chamber 27 internal volume does not haves a notable difference with time static, and now will be passed through electric current and increase, corresponding magnetic field intensity is strengthened, and the kinematics characteristic of magnetic flow liquid can level off to the kinetic characteristic of rubber, thus undertakes most of moment of torsion on θ direction.
Above in conjunction with accompanying drawing, this utility model preferred embodiment is described in detail, but this utility model is not limited to described embodiment.To those skilled in the art, in the case of without departing from principle of the present utility model and spirit, this embodiment is carried out multiple change, revises, replace and deformation still falls within protection domain of the present utility model.
