A kind of Double-cylinder high-pressure magnetorheological shock absorber
Technical field
The present invention relates to damper technical field, specially a kind of Double-cylinder high-pressure magnetorheological shock absorber.
Background technique
MR vibration damper is to utilize inductive reaction, is with the input information from monitoring car body and wheel movement sensors
Real-time response is made to road conditions and driving environment in basis, and magnetic rheological liquid is a kind of soft grain suspension of magnetism, when set on damper
After electromagnetic coil in piston is powered, the magnetic field of coil will change the rheological behavior of magnetic rheological liquid, thus in no Electrical Control
Valve processed and mechanical device it is simple in the case of, generation is swift in response, the damping force that controllability is strong, and MR vibration damper has resistance
Buddhist nun's power is adjustable, and multiple is high, is easily achieved computer variable damping real-time control and spy compact-sized and that external input energy is small
Point is increasingly subject to the great attention of engineering circles.
But MR vibration damper is when in use, has the disadvantage in that when in use, the electric current inside electromagnetic coil
Measure smaller, when can not generate biggish magnetic field and having an impact to magnetorheological fluid, the damping effect that will lead to damper is reduced, vibration
In biggish situation, damping can not be carried out to it by damper, larger, the influence experience by bus so that vehicle jolts;Also,
In use, dust can be infected on the outside of position-limiting tube, leads to Caton phenomenon occur during damping, damping can not be carried out to it;
When being placed to damper, it will lead to damper directly with ground face contact, will lead to damper damage, influence damper
Normal use;Damper at work, can do reciprocal piston motion, can generate biggish heat, influence the use of damper
Service life.

The output end in source is electrically connected.
The working principle and process for using of this damper: during using Double-cylinder high-pressure magnetorheological shock absorber, firstly,
It needs that MR vibration damper is installed, during installation, upper mounting ring 13 is connect with automobile chassis, by lower installation
Ring 2 is connect with automobile tire, can be reduced the vibration generated in vehicle traveling process by MR vibration damper, be subtracted when magnetorheological
When shaking device work, the vibration that automobile generates can promote to be passed through electric current inside electromagnetic coil 1003, so that near electromagnetic coil 1003
Magnetic field is generated, low-flow can be presented in magnetorheological fluid under the influence of a magnetic field, so that the movement inside working cylinder 1 of piston 1001 is done
It pumps, the vibration generated in vehicle traveling process is eliminated, during being installed to MR vibration damper,
By holding rubber sleeve 7 and anti-skid chequer 9, it is smaller to be effectively prevented damper skin-friction force, causes damper to occur de-
It falls and damages, meanwhile, it is more comfortable when being installed in winter to damper, by placed seat 6, can be effectively avoided pair
When damper is placed, damper is directly in contact with ground, and damper is caused to be collided with and damaged, and is subtracted magnetorheological
During shaking device work, the magnetorheological fluid that working cylinder is 1 can pass through piston 1001 by deflector hole 1004, into another chamber
Room, at this point, magnetorheological fluid can also enter inside regulating tank 1005, and full of the elastomeric bladder 1006 inside regulating tank 1005, elasticity
Capsule 1006 is full of after magnetorheological fluid, it may occur that deformation, so that the elastomeric bladder 1006 full of magnetorheological fluid passes through adjustment hole 1007
Into inside deflector hole 1004, the diameter of deflector hole 1004 is adjusted, so that mistake of the MR vibration damper in work
Deflector hole 1004 can be adjusted according to the size of vehicle vibration pressure in journey, so that the damping effect of MR vibration damper
More preferably, applicability is stronger, when the vibration pressure that automobile generates in the process of moving is greater than resistance of the magnetorheological fluid under magnetic fields
Buddhist nun's power, when leading to not carry out damping to the vibration that automobile generates, piston rod 11 drives position-arresting disk 1202 in position-limiting tube 1201
Portion pumps, by the first damping spring 1203 and the second damping spring 1204 to generating in vehicle travel process
Vibration carries out secondary shock-absorbing, improves the damping effect of MR vibration damper, when MR vibration damper due to doing up and down for a long time
Reciprocating motion causes 1201 skin-friction force of position-limiting tube to increase, and when influencing to work normally, is lubricated by 1403 Duis of oil suction sponge ring
Lubricating oil inside chamber 1402 is absorbed, and is applied to 1201 surface of position-limiting tube by oil seepage hole 1404, reduces position-limiting tube
The frictional force on 1201 surfaces, so that MR vibration damper pumps more smoothly, so that damping effect is more preferably, when
Lubricating oil inside lubrication chamber 1402 is when being finished, by oil inlet 1405 to addition lubricating oil inside lubricator stand 1401,
During MR vibration damper work, due to constantly rubbing, biggish heat can be generated, at this point, passing through semiconductor system
Cold 8 generation low temperature, and conducted by working cylinder 1 to working cylinder 1, cool down to the heat generated inside working cylinder 1,
Damper internal heat excessively high the phenomenon that causing damper to burst is prevented, the service life of damper is extended.
