Description
Technical field
The present invention relates to a kind of damping device, specifically, relate to a kind of long-stroke magnetic suspension shock absorber.
Background technique
The occasion of damping is needed generally to adopt the mechanical damper of spring and hydraulic piston parallel connection at vehicle etc. at present, spring plays the effect of buffering, piston plays the effect of damping, vibration damper is normally used for the shock and impact of the outside suppressing to be applied thereto, make vibrations on vibration damper, produce larger decay, thus reach the travelling comfort and stationarity that keep vehicle or equipment.After long-term use, spring wherein can produce lax or fatigue ruption to such vibration damper because of resiliently deformable repeatedly, make defective shock absorber and cannot use; The Sealing of hydraulic piston can, because of wearing and tearing and aging and produce oil leakage phenomenon, make vibration damper lose the effect of damper.Owing to being the vibration damper of contact-type, some HF noise signals produced in vibrations, are propagated into the other side of vibration damper, have influence on the travelling comfort of people by spring, liquid and piston.。
In damping device technical field, we retrieved following open source literatures, such as:
1, Chinese patent, application number: CN201010185898.6, title: a kind of automobile absorber assembly, summary: a kind of automobile absorber assembly, it is by connecting rod, tighten spring and spring, one is provided with for preventing the positioning seat of spring radial-play in the bottom of spring, namely one end of spring to be sleeved on positioning seat and low pressure on the end face of positioning seat, spring radially play can be prevented, thus avoid shock abnormal sound, dust cover is provided with in the joint of connecting rod, this automobile shock general name adopts common spring to carry out damping, therefore spring easily strains lax, repeated deformation easily produces lax.
2, Chinese patent, application number: CN201010190910.2, title: a kind of support shock absorber, summary: a kind of support shock absorber, it produces flange in one end of hollow shaft sleeve, the cylindrical of hollow shaft sleeve is loaded onto soft rubber sleeve and on the cylindrical of soft rubber sleeve, overcoat is installed, gland is fixed on one end of hollow shaft sleeve by the method for screw-thread fit.This support subtracts the traditional machinery type shock-absorbing of employing, easily makes shock-absorbing parts strain and be destroyed.
Summary of the invention
The object of the invention is the shortcoming and defect existed for above-mentioned vibration damper, the strong magnetism permanent-magnet material that magnetic pole is relative is adopted to replace spring and hydraulic piston, make novel magnetic suspension shock absorber, to overcome the problem of friction that existing machinery formula vibration damper exists, leakage of oil and noise transfer, simultaneously short in the deficiency such as magnetic suspension force is little by adopt the structure of taper magnet to solve stroke that Magnetic shock absorber in the past exists.
The solution of the present invention is by realizing like this: construct a kind of long-stroke magnetic suspension shock absorber, comprise damper cylinder, and be arranged on upper rings and the lower lift ring at damper cylinder two ends, described upper rings and the sliding accessory of damper cylinder connect, lower lift ring is fixedly connected with damper cylinder, is equipped with end permanent magnet inside described upper rings and lower lift ring, and described end permanent magnet comprises top permanent magnet and bottom permanent magnet, described top permanent magnet is connected with upper rings, and bottom permanent magnet is connected with lower lift ring; At least one piece of suspending permanent magnet is also provided with between described top permanent magnet and bottom permanent magnet, all sliding accessory connects described suspending permanent magnet with damper cylinder inwall, and the suspending permanent magnet magnetic force of described suspending permanent magnet and end permanent magnet and/or adjacent both ends repels each other and keeps neutral buoyancy between top permanent magnet and bottom permanent magnet.
For achieving the above object, long-stroke magnetic suspension shock absorber of the present invention, the principle of magnet two like magnetic poles repel each other is utilized to produce magnetic suspension force, by arranging the magnet that mutual magnetic force repels each other in damper cylinder, keep the balance of each permanent magnet, and each permanent magnet is all with damper cylinder, and sliding accessory connects, the permanent magnetic iron block quantity of placing is decided by the stroke of vibration damper, and the fast quantity of the longer magnet of stroke is more.The magnet of upper and lower end is connected with the suspension ring of upper and lower end soon respectively, two suspension ring are connected on two objects of needs isolation vibrations, when the stressed slide downward of upper rings, permanent magnet also moves down, the repulsion of the permanent magnet between adjacent strengthens, the pressure that opposing upper rings is downward, when the power putting on upper rings reduces gradually, the repulsion of permanent magnet spring, by upper rings pushed home.
In the present invention, as further improvement, described suspending permanent magnet comprise conical suspended permanent magnet and with conical suspended permanent magnet can be suitable concave edge suspending permanent magnet, described top permanent magnet and bottom permanent magnet are equipped with recess that can be suitable with conical suspended permanent magnet, and described conical suspended permanent magnet and concave edge suspending permanent magnet are alternately suspended in damper cylinder.Permanent-magnet material is adopted to make band taper permanent magnetic iron block or can the concave edge suspending permanent magnet of adaptive taper permanent magnet, the size of tapering depends on the stroke of vibration damper and the requirement of suspending power size, taper angle is less, stroke and suspending power larger, taper angle is larger, stroke and magnetic suspension force less, can according to use requirement determine.Permanent magnet in damper cylinder, all installs guide runner additional between permanent magnet and damper cylinder inwall, and each magnet piece can be slided up and down, and needs to add certain lubricant oil in damper cylinder, smooth and easy to ensure that all magnet can slide soon in the vertical direction.
In the present invention, preferably, conical suspended permanent magnet A is provided with, conical suspended permanent magnet B in described damper cylinder, and a concave edge suspending permanent magnet A, described conical suspended permanent magnet A, concave edge suspending permanent magnet A and conical suspended permanent magnet B arranges from top to bottom and is suspended in damper cylinder, adopts the conical suspended permanent magnet of 2 groups to coordinate 1 group of conical suspended permanent magnet B, can meet the needs of general automobile shock, 2 groups of magnet is the stroke in order to increase vibration damper, strengthens damping effect.
The present invention has following beneficial effect:
1. in the present invention, utilize the mutual expelling force between permanent magnet, make the repulsion between permanent magnet play the effect of damping.
2., in the present invention, permanent magnet is made taper permanent magnet and can the concave edge suspending permanent magnet of adaptive taper permanent magnet, the stroke of permanent magnet movement can be strengthened, strengthen shock-proof effect, with employing cylindrical magnet iron as compared with vibration damping material, doubly, shock-proof effect is obvious for the long 2-3 of shock-absorbing stroke.
3, the permanent magnet mechanism stable in the present invention, not fragile, be convenient to safeguard.
4, economy and durability of the present invention, structure is simple, low cost of manufacture.
