Description
Technical field
The utility model relates to a kind of damping device, specifically, relates to a kind of long stroke magnetic suspension vibration damper.
Background technique
At present need the occasion of damping generally to adopt the mechanical damper of spring and hydraulic piston parallel connection at vehicle etc., spring plays the effect of buffering, piston plays the effect of damping, vibration damper normally is used for the shock and impact of the outside that suppresses to be applied thereto, make vibrations produce larger decay at vibration damper, thereby reach travelling comfort and the stationarity that keeps vehicle or equipment.Such vibration damper is after long-term the use, and spring wherein can produce because of resiliently deformable repeatedly and relax or fatigue ruption, makes defective shock absorber and can't use; The Sealing of hydraulic piston can and wear out because of wearing and tearing and produce oil leakage phenomenon, makes vibration damper lose the effect of damper.Owing to be the vibration damper of contact-type, some HF noise signals that produce in the vibrations propagate into the other side of vibration damper by spring, liquid and piston, have influence on people's travelling comfort.
In the damping device technical field, we have retrieved following open source literatures, for example:
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, be provided with a positioning seat that is used for preventing the spring radial-play in the bottom of spring, be an end of spring be sleeved on the positioning seat and low pressure on the end face of positioning seat, can prevent radially play of spring, thereby avoided the bump abnormal sound, be provided with dust cover in the joint of connecting rod, this automobile shock general name adopts common spring to carry out damping, therefore strain is lax easily for spring, and repeated deformation produces lax easily.
2, Chinese patent, application number: CN201010190910.2, title: a kind of support shock absorber, summary: a kind of support shock absorber, it is that a end at hollow shaft sleeve produces flange, load onto soft rubber sleeve at the cylindrical of hollow shaft sleeve and at the cylindrical of soft rubber sleeve overcoat is installed, gland is fixed on an end of hollow shaft sleeve by the method for screw-thread fit.This support subtracts adopts traditional machinery type shock-absorbing, destroyed so that the shock-absorbing parts strain easily.
Summary of the invention
The purpose of this utility model is the shortcoming and defect that exists for above-mentioned vibration damper, adopt the relative strong magnetism permanent-magnet material of magnetic pole to replace spring and hydraulic piston, make novel magnetic suspension vibration damper, to overcome the problem of friction, leakage of oil and noise transfer that existing machinery formula vibration damper exists, solve the deficiencys such as the short and magnetic suspension force of stroke that Magnetic shock absorber in the past exists is little by the structure that adopts taper magnet simultaneously.
Scheme of the present utility model is by such realization: construct a kind of long stroke magnetic suspension vibration damper, comprise damper cylinder, and the upper rings and the lower lift ring that are arranged on the damper cylinder two ends, described upper rings is joined with the damper cylinder cunning and is connected, lower lift ring is fixedly connected with damper cylinder, and described upper rings and lower lift ring inboard are equipped with the end permanent magnet, and described end permanent magnet comprises top permanent magnet and bottom permanent magnet, described top permanent magnet is connected with upper rings, and the bottom permanent magnet is connected with lower lift ring; Also be provided with at least one suspending permanent magnet between described top permanent magnet and the bottom permanent magnet, described suspending permanent magnet is all joined with damper cylinder inwall cunning and is connected, 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 balance to be suspended between top permanent magnet and the bottom permanent magnet.
For achieving the above object, the long stroke magnetic suspension of the utility model vibration damper, utilize the principle of magnet two like magnetic poles repel each other to produce magnetic suspension force, by the magnet that mutual magnetic force repels each other that arranges in damper cylinder, the balance that keeps each permanent magnet, and each permanent magnet is all joined with the damper cylinder cunning and is connected, and 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 respectively soon, two suspension ring are connected on two objects that need the isolation vibrations, when the stressed down sliding of upper rings, permanent magnet also moves down, the repulsion of the permanent magnet between adjacent strengthens, and the downward pressure of opposing upper rings is when the power that puts on upper rings reduces gradually, the repulsion of permanent magnet spring is with the upper rings pushed home.
In the utility model, as further improvement, described suspending permanent magnet comprise conical suspended permanent magnet and with conical suspended permanent magnet can be suitable the concave edge suspending permanent magnet, described top permanent magnet and bottom permanent magnet be equipped with can with the suitable recess of conical suspended permanent magnet, described conical suspended permanent magnet and concave edge suspending permanent magnet alternately are suspended in the damper cylinder.Adopt permanent-magnet material to make with taper permanent magnetic iron block or concave edge suspending permanent magnet that can 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 are just larger, taper angle is larger, stroke and magnetic suspension force are just less, can determine according to the requirement of usefulness.Permanent magnet in the damper cylinder all installs guide runner additional between permanent magnet and decompression cylinder inwall, each magnet piece can be slided up and down, and needs to add certain lubricant oil in the cylinder, soon can be smooth and easy at the upper and lower upward sliding to guarantee all magnet.
In the utility model, as preferred version, be provided with conical suspended permanent magnet A in the described damper cylinder, conical suspended permanent magnet B, and concave edge suspending permanent magnet A, described conical suspended permanent magnet A, concave edge suspending permanent magnet A and conical suspended permanent magnet B arrange from top to bottom and are suspended in the damper cylinder, adopt 2 groups conical suspended permanent magnet to cooperate 1 group of conical suspended permanent magnet B, can satisfy the needs of general automobile shock, 2 groups of magnet are in order to increase the stroke of vibration damper, to strengthen damping effect.
The utlity model has following beneficial effect:
1. in the utility model, utilize the mutual expelling force between the permanent magnet, so that the repulsion between the permanent magnet plays the effect of damping.
2. in the utility model, permanent magnet is made taper permanent magnet and concave edge suspending permanent magnet that can adaptive taper permanent magnet, can strengthen the stroke that permanent magnet moves, strengthen shock-proof effect, compare as vibration damping material with employing cylindrical magnet iron, the long 2-3 of shock-absorbing stroke times, shock-proof effect is obvious.
3, the permanent magnet mechanism stable in the utility model is not fragile, is convenient to safeguard.
4, the utility model economy and durability is simple in structure, low cost of manufacture.
