When not turning knob 18, upper and lower two magnetism shielding hoods, 8 position is motionless, and magnetism shielding hood 8 does not cover permanent magnet 5, make,
Permanent magnet 5 in lower two piston assemblies fully comes out, then permanent magnet 5 produce magnetic field through the N poles of permanent magnet 5 →
The S poles of the other end → permanent magnet 5 of the end → damp channel → cylinder barrel → damp channel → piston only 4 of piston only 4,
Then damp channel produces very heavy damping power due to there is the action of a magnetic field, then；Now, upper and lower two piston assemblies all work, and produce
Raw very heavy damping power.
When damping adjusting power is needed, the position of two magnetism shielding hoods 8 can be adjusted by knob 18 is rotated to an angle
Put, make magnetism shielding hood 8 drive the movement of magnetism-guiding hood 7 to cover permanent magnet 5, when piston assembly is covered by magnetism shielding hood 8 and magnetism-guiding hood 7 completely
Afterwards, the magnetic field that permanent magnet 5 in magnetism shielding hood 8 is produced is shielded, it is impossible to the magnetic flow liquid generation effect outside magnetism shielding hood 8, then
Damping force reduces or does not produce damping.
In addition, the setting by drive mechanism, can make two magnetism shielding hoods 8 be in not covering permanent magnet 5 or cover
The state of a part for permanent magnet 5, the damping force that now MR damper is produced are maximum；Or magnetism shielding hood 8 cover with
Its permanent magnet 5 for coordinating, another magnetism shielding hood 8 do not cover the permanent magnet 5 coordinated with which, the resistance that now MR damper is produced
The damping force that Buddhist nun's power is produced when covering permanent magnet 5 than two magnetism shielding hoods 8 is little；Or two magnetism shielding hoods are in and cover completely forever
The state of magnet 5, the damping force that now MR damper is produced are minimum, close to zero.
The present invention is exemplarily described above in association with accompanying drawing.Obviously, the present invention is implemented
The restriction of formula.As long as employ the improvement of the various unsubstantialities that method of the present invention design and technical scheme are carried out；Or not
It is improved, the above-mentioned design of the present invention and technical scheme are directly applied to into other occasions, in protection scope of the present invention
Within.
