Working procedure of the present utility model is as follows:
Utilize the intensity of coil 3 controlling magnetic fields, and then control the rigidity of magnetic rheology elastic body 10.
As shown in Figure 2, under the effect of pressure, high-voltage oil liquid enters from filler opening A, and the magnetic rheology elastic body 10 being now connected with track bar 7 produces compressive strain under the effect of pressure, so filler opening A moves on gradually, is opened, and fluid flows out from oil outlet B.Along with the increase of pressure, the aperture of filler opening A increases gradually, thereby realizes the continuous adjusting of flow.
Coil 3 produces magnetic field under the effect of ECU (Electrical Control Unit), the increase along with magnetic intensity before unsaturation of the rigidity of magnetic rheology elastic body 10 increases gradually, the active force that magnetic rheology elastic body 10 acts on track bar 7 also increases gradually, thereby realize the control of the cracking pressure of filler opening A, and then realize the control of damping size.
As shown in Figure 3, when the oil liquid pressure at filler opening A place reduces, track bar 7 resets under self elastic reaction of magnetic rheology elastic body 10, the fluid of cut-off filler opening A.
The beneficial effects of the utility model are:
The utility model is simple and compact for structure, and cost is relatively cheap, easy to process.Can be controlled and be realized different cracking pressures by magnetic intensity, response be fast, realizes flow continuous control.
