Abstract
The utility model relates to a permanent suspension damper whose homogeneities are connected in series relative to a line. The permanent suspension damper whose homogeneities are connected in series relative to a line is characterized in that a plurality of permanent magnets whose homogeneity magnetic poles are opposite are arranged in a telescopic cylinder, and are mutually kept definite distance under the action of homogeneity repulsion. The distance of the permanent magnets is nearer, and repulsion force is larger. The mutual repulsion force can provide non-linear elasticity for two ends of the telescopic cylinder. Due to the fact that the elasticity and a bounce range are square inverse relation, therefore, excellent high-frequency shock isolation can be provided for the two ends of the telescopic cylinder. The permanent suspension damper whose homogeneities are connected in series relative to a line has simple structure, hard and soft compromise, infinite working life, strong cold resistance, high reaction speed, high speed motion, and no noise. The permanent suspension damper whose homogeneities are connected in series relative to a line can be used for all the equipment needed to isolate vibration of an automobile, a motorcycle, a train, a bicycle, an aeroplane, etc.
Description
The utility model relates to a kind of vibration damper.The permanent-magnet suspended damper of forming by the relative permanent magnet of the some straight lines series connection same sexes, abrasionproof lasso, top cylinder, doffing, loam cake, lower cover and rotating shaft etc. particularly.
In vibration damper in the past,, generally adopt steel helical spring or leaf spring (tower spring) to reach the purpose of damping for the effective isolation vibrations.Because above two kinds of springs all are to utilize the restorable ability of object, elastomeric deformation is directly proportional with suffered load, i.e. Hooke (HOOKE) law.When load doubles, elastomer deformation also doubles, and this relation generally is linear.Because the frequent deformation that this spring need carry out repeatedly when work is easy to generate plasticity, and self-oscillation easily takes place, and easily produces tired, fracture, temperature is low more obvious more.Its working life is limited, because elasticity is linear, load is little, deformation is big, and noise is big, the high-frequency vibration isolating power is little, and functional reliability is low.
The purpose of this utility model be exactly the vibration damper that will change in the past be to utilize the restorable ability of object to obtain elasticity.This kind novel damping device is with the relative permanent magnet of the straight line series connection same sex (S-N N-S S-N ...) the resulting magnetic suspension of repulsive force that produced between per two same pole reaches good vibration isolation.Because the elasticity that magnetic suspension provided does not have any object deformation, reliable operation does not have fatigue, and non-cracking is low temperature resistant, the work noise free, and the life-span is unlimited.Because elasticity that magnetic suspension produced is that inverse square concerns that along with the continuous increase of load, the variable in distance between two magnet is more and more littler in the increase of load with the variable in distance between two magnet, promptly load and distance be changed to non-linear.This characteristic can improve the vibration isolation performance greatly, can provide bigger load, and the extending amount of permanent-magnet suspended damper is very little, and can avoids self-oscillation, and high frequency oscillation is had extremely strong buffer action.This kind novel damping device, volume is little, load is big, and when with neodymium iron boron (Nd-Fe-B) when doing magnet, its cylinder diameter is 5.5 centimetres.Height is 5.5 centimetres, and heavily about 840 grams the time can provide the most about 1000 kilograms magnetic suspension force.In sum, this permanent-magnet suspended damper damping effect is fabulous, hard and soft taking into account, carry big, low temperature resistant undeformed, do not have fatigue, non-cracking, volume is little, noise is little, simple in structure, safe and reliable, long service life.All need completely cut off in the traffic tool and production and lifestyle device of vibrations to can be used for automobile, train, motorcycle, bicycle, battlebus, aircraft etc.
With reference to the accompanying drawings permanent-magnet suspended damper is elaborated below: accompanying drawing 1 is the single-stage permanent-magnet suspended damper, and accompanying drawing 2 is the multiple permanent magnet suspended damper.When vibration damper carries, doffing (7) is pressed into top cylinder (6), because the quiet permanent magnet (1) in the top cylinder, moving permanent magnet (2), free permanent magnet (3) distance between them is compressed, again because permanent magnet is the series connection of the straight line same sex, under the effect that the same sex is repelled each other, powerful repulsive force has overcome the pressure that carrying is produced, make it keep the suspension balance, two same sex magnet distance is near more, the repulsive force that is produced is just big more, the vibrations that therefore moving permanent magnet (2) is produced can not pass to quiet permanent magnet (1), thereby play effective cushioning effect.(4) be loam cake, (5) are the abrasionproof lasso, and (8) are dustproof bellows, and (9) are lower fulcrum bar, and (10) are lower cover, and (11) are rotating shaft.
Claims (5)
1, a kind of permanent-magnet suspended damper that is used for isolating vibrations, it is characterized in that being made up of quiet permanent magnet (1), moving permanent magnet (2), free permanent magnet (3), loam cake (4), abrasionproof lasso (5), top cylinder (6), doffing (7), lower cover (10) and rotating shaft (11), the equal same sex of each permanent magnet is relative.
2, permanent-magnet suspended damper according to claim 1 has at least a quiet permanent magnet (1) and moving permanent magnet (2) to constitute.
3,, have at least a free permanent magnet (3) to constitute according to claim 1 described permanent-magnet suspended damper.
