Abstract
The utility model provides a double-barrel shock absorber which comprises a position rod, a work cylinder and an oil storing cylinder, which are coaxially arranged with one another, wherein a compression valve and a compensation valve are arranged at the lower part of the work cylinder, a position is arranged at the lower part of the position rod, the position is provided with a rebound valve and a circulation valve, a guide base and an oil seal are arranged at the top of the work cylinder, a dust cover is arranged at the top of the oil storing cylinder, a magnet is fixedly arranged in each of the middle of the lower end of the piston rod and the middle of the position at the bottom of the work cylinder, and one opposite ends of the magnets are homopolar, which are N poles or S poles at the same time. The shock absorber has the working principle that electromagnets are electrified to generate the magnetism; and one opposite ends of the electromagnets are repellent mutually, so that the outside impact and shock can be slowed down, and the excessive wear of the shock absorber can be avoided when the impact or the shock is too high.
Description
Technical field
The utility model relates to the vibration damper field, relates in particular to a kind of dual-tube shock absorber that has electromagnet.
Background technique
Dual-tube shock absorber is a vibration damper commonly used at present and technological comparative maturity; Its working principle is; When relative movement appearred in vibrations between vehicle body and vehicle bridge, the piston in the vibration damper moved up and down, and the damping oil in the vibration damper clutch release slave cylinder flows in another chamber through different holes from a chamber repeatedly.The intermolecular interior friction of friction between hole wall and damping oil and fluid at this moment forms damping force to vibrations, and making the thump Conversion of energy is damping oil heat energy, is dispersed in the atmosphere by the vibration damper absorption again.Traditional dual-tube shock absorber only relies on flowing of damping oil and moving up and down of piston, will impact and vibrations discharge.
Summary of the invention
In order to overcome the above problems, the utility model discloses a kind of dual-tube shock absorber that has electromagnet.This dual-tube shock absorber is provided with the relative electromagnet of homopolarity through bottom in the cylinder body of vibration damper, in vibration damper work, and electromagnet energising, the electrode homopolar-repulsion can slow down that damping oil that foreign impacts or vibrations cause flows and piston moves up and down.
Dual-tube shock absorber comprises piston rod, clutch release slave cylinder and the oil storage cylinder of coaxial setting, and the clutch release slave cylinder bottom is provided with compression valve and recuperation valve; The bottom of piston rod is provided with piston, rebound valve and flowing valve; The top of clutch release slave cylinder is provided with guide holder and oil sealing, and the top of oil storage cylinder is provided with dust-proof cover, is set with magnet respectively in the middle of the piston of the centre of piston-rod lower end and clutch release slave cylinder bottom; The end that magnet is relative is a homopolarity, is the N utmost point or the S utmost point simultaneously.
Magnet is the electromagnet of bar shaped.
When vibration damper is not worked, the electromagnet no electric circuit, electromagnet does not have magnetic, can not repel each other; In the time of vibration damper work, connect the power supply of electromagnet, electromagnet produces magnetic; And be that homopolarity is relative, repel each other, make the mutual repulsion of electromagnet can slow down extraneous impact and vibrations; Avoid foreign impacts or vibrations violent, cause damping oil to flow violent and piston dried move down too big; Cause the vibration damper corrupted, even lost efficacy.
Description of drawings
Fig. 1 is the structural representation of this dual-tube shock absorber,
Accompanying drawing is indicated tabulation: 1-dust-proof cover, 2-piston rod, 3-guide holder, 4-clutch release slave cylinder, 5-flowing valve, 6-recuperation valve, 7-compression valve, 8-oil storage cylinder, 9-rebound valve, 10-electromagnet.
Embodiment
Further illustrate the utility model below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1; The utility model comprises piston rod 2, clutch release slave cylinder 4 and the oil storage cylinder 8 of coaxial setting; Clutch release slave cylinder 4 bottoms are provided with compression valve 7 and recuperation valve 6, and the bottom of piston rod 2 is provided with piston, rebound valve 9 and flowing valve 5, and the top of clutch release slave cylinder 4 is provided with guide holder 3 and oil sealing; The top of oil storage cylinder 8 is provided with dust-proof cover 1; Be set with electromagnet 10 respectively in the middle of the piston of the centre of piston rod 2 lower ends and clutch release slave cylinder 4 bottoms, electromagnet 10 relative ends are homopolarity, are the N utmost point or the S utmost point simultaneously.
Fig. 1 is that the N of electrode is extremely relative, and during vibration damper work, electromagnet 10 energisings produce magnetic, form the power of repelling each other between the last lower magnet.As foreign impacts or when vibrations, piston rod 2 moves down, and power-on and power-off magnet 10 is approaching, and repulsive force is big more each other, foreign impacts or vibrations, magnet up and down the closer to, repulsion is big more.The repulsion of magnet can slow down the impact or the vibrations in the external world, reaches the effect of damping.
