Description

The dual coil electromagnetic vibration damper
Technical field
The utility model relates to a kind of vehicular shock absorber that improves stability in the Vehicle Driving Cycle process, is specifically related to a kind of dual coil electromagnetic vibration damper.
Background technique
In the Vehicle Driving Cycle process, in suspension system, because elastic element is hit, produce vibrations, for improving the Vehicle Driving Cycle smoothness, in suspension, with elastic element, be installed in parallel vibration damper.At present, the vibration damper that adopts on vehicle suspension mostly is passive type, such as traditional passive type hydraulic damper realizes cushioning effect by the damping that fluid flows through one-way valve, can not change the vibration damper damping constant according to traffic information, driver and passenger comfort level when driving can not get maximum satisfied.The active suspension system of employing damping force adjustable and spring rate can be according to the size of road conditions and Vehicle Driving Cycle condition change damping force and spring rate, to meet the requirement of riding comfort and travelling and driving safety.application number is that 201020628771.2 patent documentation discloses a kind of electromagnetic shock absorber, comprise upper cylinder, lower cylinder body, one end of upper cylinder is arranged in lower cylinder body, upper cylinder and lower cylinder body are slidably matched, in upper cylinder, be provided with decoupling rod, in lower cylinder body, be provided with the stir yourself axle, the lower end of decoupling rod is provided with the first permanent magnet, the upper end of movable axis is provided with the second permanent magnet, the first permanent magnet, the second permanent magnet is that the S utmost point same sex is oppositely arranged, it is characterized in that: on described decoupling rod, be provided with the first coil, on movable axis, be provided with the second coil, the first coil, the second coil is connected with the power supply of outside respectively, described decoupling rod, movable axis are threaded in respectively on upper cylinder, lower cylinder body.The shortcomings such as it is slow that this electromagnetic shock absorber exists the response time, and working life is short.
The model utility content
The purpose of this utility model is to provide a kind of dual coil electromagnetic vibration damper of new structure, its not only the response time fast, and can effectively solve the problem of clutch release slave cylinder wearing and tearing, longer service life.
For realizing this damping purpose, the technical solution of the utility model is: a kind of dual coil electromagnetic vibration damper, comprise clutch release slave cylinder, and in described clutch release slave cylinder, be provided with first piston bar, first piston, the second piston rod, the second piston; The first piston bar is connected with first piston, and the second piston rod is connected with the second piston; Described first piston bar is wound with the first coil, and described the second piston rod is wound with second coil opposite with the first coil winding-direction, and described the first coil is connected with power supply respectively with the second coil; In described clutch release slave cylinder, two ends are provided with guide holder; On first piston bar and the second piston rod, be respectively equipped with limiting stopper, between described limiting stopper and guide holder, be provided with the elasticity thing, between first piston and the second piston, be provided with the elasticity thing, the extension of described first piston bar is provided with limit stoper, described the second piston rod is the inner hollow-core construction that is provided with vestibule, the bottom of described the second piston rod radially is provided with oil duct, the two ends of described oil duct are connected conducting with described piston rod vestibule with the oil storage cylinder inner chamber respectively, the bottom of described clutch release slave cylinder is provided with bottom valve, on described bottom valve, is provided with magnet.
As improvement of the present utility model, the elasticity thing between described limiting stopper and wire seat is fixedly mounted on limiting stopper.
As improvement of the present utility model, described first piston bar and the second piston rod surface all are covered with a metal film layer.
As improvement of the present utility model, the first coil is connected with power supply with the fairlead that the wire of the second coil passes on clutch release slave cylinder.
The structural advantage of the utility model is: on first piston bar and the second piston rod, be equipped with coil on the one hand, coil produces magnetic force under the effect of electric current, thereby reaches the effect of damping; Simultaneously, between first piston and the second piston, be provided with the elasticity thing, can be in the situation that the effect of damping be played in power failure; Solved existing vibration damper due to the permanent magnet magnetization that is provided with permanent magnet and causes, the problem that the response time is slow.Magnet is set on the other hand in clutch release slave cylinder, by magnet, the clutch release slave cylinder thin iron powder that gets off that weares and teares is adsorbed, hydraulic oil in oil storage cylinder is kept clean, thereby alleviated when piston is reciprocating along the clutch release slave cylinder inwall in clutch release slave cylinder and the wearing and tearing of clutch release slave cylinder inwall, solve preferably the problem of clutch release slave cylinder wearing and tearing, simultaneously because hydraulic oil seems limpid after the thin iron powder of magnet adsorption, guaranteed the mobile smoothness of hydraulic oil, guarantee the stability of vibration damper, improved the comfort level of car.Change piston rod into hollow-core construction simultaneously, adjustable lever is built in the piston rod vestibule, not only can regulate as required, and compact structure, saved space.
