One permanent magnet is arranged on the lower part of the cylinder body cover and on the upper part of the cylinder body bottom respectively; the upper end of a guide rod is connected with a dust cover, and the lower end of the guide rod is connected with a movable permanent magnet which can slide and move freely in the cylinder body; a current reversing key is arranged on an external round face of the external cylinder body, and the touching key of the current reversing key is contacted with the inner wall of the dust cover, and the current reversing key is connected with a circuit and the two field coils: the upper field coil and the lower field coil. The up and down movement of the movable permanent magnet is subjected to the damping effect of the upper and lower field coils and the upper and lower magnetic fields of the magnet, reaching the goal of shock absorption. The magnetic force shock-absorber with the advantages of simple structure and adjustable damping value can be used for the shock protection and shock resistance of automobiles, precision machine tools, etc.
Description
The utility model relates to a kind of vibration damping, antivibration device, particularly a kind of magnetomechanical damping device that is used for vibration dampings such as automobile, motorcycle, precision machine tool, antivibration.
Existing vibration damping equipment is useful on straight-linely as spring with have the damper of oil, air or other media, also is useful on the electromagnetic damper that rotatablely moves.In these dampers, except that electromagnetic damper, the other types damper all is difficult to adjust damping value at any time according to the operating mode situation.And, can only be used for rotation and twist motion for electromagnetic damper, and be unsuitable for directly being used in straight-line occasion.
The purpose of this utility model provides a kind of straight line motion occasion that is directly used in, the electromagnetism that its damping value can be adjusted at any time with the operating mode situation and the magnetic force vibration damper of permanent-magnet structure.
The purpose of this utility model is achieved in that
Whole vibration damper is made of dust-proof cover, guide rod, cylinder body and exciting circuit etc.Cylinder body below the tubular dust-proof cover is made up of inner cylinder body and outer cylinder body.Be set with two cartridge type coils concentric up and down between the interior outer cylinder body with cylinder body; Respectively there is one to go up permanent magnet and following permanent magnet under the lid of cylinder body and on the cylinder bottom.Extend into lower end of the guide rod in the inner cylinder body with its concentric that be connected and cylinder cap by cylinder body and last permanent magnet in the dust-proof cover, be connected with the movable permanent magnet iron that can in inner cylinder body, slide up and down.The outer cylinder body outer peripheral surface of cylinder body top have one with field coil up and down, and the current reverser that is connected with exciting circuit, the touching button of reverser and dust-proof cover inwall rubbing contact.
Advantage of the present utility model is to have used simultaneously electromagnetism and permanent magnetism, and its damping value can be adjusted good damping result with the variation of operating mode; It is simple in structure, easy to manufacture, is easy to control and pollution-free, and the life-span is long and easy to maintenance.
Below in conjunction with drawings and Examples the utility model is further described:
Accompanying drawing 1 is a structural representation of the present utility model.
As shown in Figure 1, the utility model is a telescopic shock absorber, it by dust-proof cover (2), guide rod (3), cylinder cap (12), up and down permanent magnet (4 and 10), interior outer cylinder body (5 and 6), up and down solenoid (7 and 9), movable permanent magnet iron (8), current reverser (13), connecting ring (1 and 11) and exciting circuit (15) are formed up and down.Exciting circuit (15) is made up of variable resistor R and power supply E.Wherein dust-proof cover (2), guide rod (3), last connecting ring (1) and movable permanent magnet iron (8) constitute an integral body, are connected by the movable part of last connecting ring (1) with the outside.Miscellaneous part constitutes one and is connected with the basic component of outside by following connecting ring 13.
The cylinder body of vibration damper (14) mainly is made up of interior outer cylinder body (5 and 6).Be set with two tubular field coils (7 and 9) up and down between the interior outer cylinder body (5 and 6).There are last permanent magnet (4) and cylinder cap (12) in the upper end of cylinder body (14).Following permanent magnet (10) is arranged at inner cylinder body (5) bottom.Cylinder cap (12) is passed in the upper end of guide rod (3) and concentric connection of dust-proof cover (2), lower end, upward permanent magnet (4) is connected with the movable permanent magnet iron (8) that freely slides up and down in inner cylinder body (5).Dust-proof cover (2) moves up and down along cylinder body (14) outer wall with guide rod (3).The current reverser (13) that links to each other with last lower coil (7 and 9) and exciting circuit (15) is housed on outer cylinder body (6) outer peripheral surface.The inwall rubbing contact of the touching button of reverser (13) and dust-proof cover (2).The size of each permanent magnet and the Number of ampere turns of last lower coil can be made according to the size design of required magnetic force.Exciting circuit is general simple straight bleeder circuit, also reverser (13) can be replaced by sensor and corresponding circuit thereof, and variable resistor R part also can increase sensor and correspondent control circuits.The reverser of present embodiment (13) has two groups of contacts up and down, and dust-proof cover (2) touches reverser (13) when moving up and down touching button makes its contact contact conversion, changes the purpose that goes up middle current direction of lower coil (7 and 9) and magnetic direction thereby reach.
When make movable permanent magnet iron (8) when moving downward because of vibration, dust-proof cover (2) moves downward the touching button that makes reverser (13) and presses to one group of contact, below, inhale mutually with the magnetic field of movable permanent magnet iron (8) in the magnetic field that exciting curent produces coil (7), and repel each other with it in the magnetic field that lower coil (9) produces, thereby produce damping force to hinder the motion of movable permanent magnet iron (8).Along with movable permanent magnet iron (8) moves downward, the electromagnetic force of two coils (7 and 9) weakens gradually to the effect of movable permanent magnet iron (8), and permanent magnet (10) is that repulsive force is increasing to the resistance that movable permanent magnet iron (8) produces down, has remedied the deficiency of electromagnetic force.And when movable permanent magnet iron (8) when moving upward, reverser (13) makes its one group of contact separation in below last one group of contact contact because of dust-proof cover (2) moves upward, make the current reversal in the lower coil (7 and 9) thus and produce opposite magnetic field, with the motion generation damping function of last permanent magnet (4) movable permanent magnet iron (8).When working conditions change, can by adjust variable resistor R also or the size of adjusting exciting curent by automatic control changing electromagnetic force, thereby reach the purpose that changes its damping value.
