Description
Technical field
The present invention relates to automobile shock technical field, specially a kind of magnetic suspension shock absorber and using method.
Background technology
At present the occasion of damping is needed typically using the mechanical damper that spring and hydraulic piston are in parallel, bullet in vehicle etc.
Spring plays a part of buffering, and piston plays a part of damping, and damper is typically used for the shake of the outside for suppressing to be applied thereto
It is dynamic to make vibrations that larger decay is produced on damper with impact, so as to reach the comfortableness that keeps vehicle or equipment and steady
Property.After long-term use, spring therein can produce lax or fatigue rupture to such damper because of elastic deformation repeatedly,
Make defective shock absorber and cannot use；The seal of hydraulic piston can make damper because of abrasion and aging and produce oil leakage phenomenon
Lose the effect of damper.Damper due to being contact, in vibrations produce some HF noise signals, by spring,
Liquid and piston travel to the other side of damper, have influence on the comfortableness of people.
Therefore, people start to develop contactless damper, and we retrieved following some open source literatures, for example：
One, Chinese patent, 2016.1.201, Guangxi University, long-stroke magnetic suspension shock absorber, application number CN102808882B should send out
It is bright to have the advantages that：
1. in the invention, using the mutual expelling force between permanent magnet so that the repulsion between permanent magnet plays the effect of damping.
2. in the invention, the concave edge suspension for making taper permanent magnet and can be adapted to taper permanent magnet permanent magnet is forever
Magnet, can increase permanent magnet movement stroke, increase shock-proof effect, with using cylindrical magnet iron as vibration damping material phase
Than suspension stroke is long 2-3 times, and shock-proof effect is obvious.
3rd, the permanent magnet mechanism stable in the invention, is hardly damaged, and is easy to safeguard.
4th, the invention economy and durability, simple structure, low cost of manufacture.
Two, Chinese patent, permanent-magnet suspended damper Cui Han puts down
1994.11.23 CN2183468Y 。
The utility model is related to a kind of damper.Particularly by some linear strings in conjunction with the relative permanent magnet of property, abrasionproof lasso,
The permanent-magnet suspended damper of the compositions such as top cylinder, lower cylinder, upper lid, lower cover and rotating shaft.
In conventional damper, in order to effectively isolate vibrations, typically using steel helical spring or leaf spring（Tower spring）
To reach the purpose of damping.Because both the above spring is using the restorable ability of object, the deformation of elastomer and institute
The load received is directly proportional, i.e. Hooke（HOOKE）Law.When load doubles, elastomer deformation also doubles, this relation
It is usually linear.Because this spring operationally needs the frequently deformation for carrying out repeatedly easily to produce plasticity, easily occur certainly
Impulse and swing, and be also easy to produce fatigue, fracture, temperature is more low more obvious.Its service life is limited, due to elastic linear, load is little,
Deformation is big, and noise is big, high-frequency vibration isolating power is little, and functional reliability is low.
The purpose of the utility model seeks to change conventional damper to be obtained using the restorable ability of object
Elasticity.This kind of shock damper is in conjunction with the relative permanent magnet of property with linear string（S-N N-S S-N ...）Each two same magnetic
Magnetic suspension between pole obtained by produced repulsive force is reaching good vibration isolation.Due to the elasticity that magnetic suspension is provided
Without any object deformation, reliable operation is low temperature resistant without fracture without fatigue, and work noiselessness, and the life-span is unlimited.Due to magnetic suspension institute
Distance change of the elasticity of generation between the increase of load and two magnet turns to inverse square relation, with the continuous increasing of load
Plus, the change of the distance between two magnet is less and less, i.e., load turns to non-linear with the change of distance.This characteristic is greatly improved
Vibration isolation performance, it is possible to provide larger load, and the stroke very little of permanent-magnet suspended damper, and can avoid from impulsing
Swing, there is extremely strong buffer action to high frequency oscillation.This kind of shock damper, small volume, load are big, when with neodymium iron boron（Nd-
Fe-B）When doing magnet, its cylinder diameter is 5.5 centimetres.A height of 5.5 centimetres, the largest of about 1000 can be provided when weighing about 840 grams
Kilogram magnetic suspension force.In sum, this permanent-magnet suspended damper damping effect is fabulous, hard and soft to take into account, and carries big, low temperature resistant
It is undeformed, without fatigue, without fracture, small volume, little noise, simple structure, safe and reliable, long service life.Can be used for automobile, fire
Car, motorcycle, bicycle, battlebus, aircraft etc. all need isolation vibrations the vehicles and production and lifestyle device in.
It is perfection that this two patents are seen, actually used to use, and is that soldier is played on paper,
1. it is complicated that the vehicles run on road, and the normal super changes in amplitude of damper Jing, permanent magnet is very easy to smash.
2, in the case of carrying, the amplitude of vibration of damper is very little, and maglev region is limited.
3, such magnetic suspension shock absorber is the principle repelled each other according to the magnetic same sex, and the size of repulsive force is flat with distance
Side is inversely proportional to, and with magnetic field intensity into back-to-front ratio, this is magnetomechanics First Law, is Coulomb's law, then authoritative theory, also must
Reality must be met,, through multiple authentication, permanent magnet does not meet magnetomechanics First Law for I, permanent magnet repelling at a distance,
Closely do not repel or attract, so, such magnetic suspension shock absorber is pseudo- proposition.In the magnetic suspension in the fields such as damper, bearing
Technology, actually used all to go wrong as long as having used the repulsive force of permanent magnet, loss is heavy, and a law is occurred in that
Leak, problem is not imaginable.
The present invention is relevant with automobile absorber, especially with regard to a kind of magnetic suspension shock absorber.
The content of the invention

Larger decay is produced on shake device, so as to reach the comfortableness and stationarity that keep vehicle or equipment, the magnetic suspension of the present invention subtracts
Shake device well beyond and existing damper can be substituted, advantage that with other damping noise reduction modes can not be when.
Fig. 1 is referred to, in shock absorber body 11, when two permanent magnet same sexes of AB are relative, in the y-axis direction, when A consolidates
Fixed, B is mutually exclusive in the range of h1, and is that repulsive force increases with the diminution of distance, in the range of h2, repulsive force be with
Attraction is also reduced or becomes in the diminution for distance.This feature of permanent magnet is not meet present magnetic force theory
's.And, existing theory is also only illustrated in y-axis direction, tells that in the direction of the x axis, AB is just without table in the direction of the x axis
When relative, B is a libration point, and this equalization point has and a little changes, and B just produces a power, this power we claim it to cry side
Thrust, this side-thrust only occurs in the magnetic induction width of A, and more than this width, the direction of side-thrust becomes reverse, becomes
Side suction.And x-axis is actually perpendicular to a face of y-axis, side-thrust is the power on this face.Above-mentioned discovery, I
It is referred to as side dianoetic to it.
