Description
[technical field]
The utility model relates to the technical field of the technical field of vibration damper, particularly adjustable electromagnetic shock absorber.
[background technique]
Vibration damper (Vibration Damper), concussion when vibration damper is mainly used to suppress rebound after spring shock-absorbing and the impact from road surface.When through uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, spring self also has to-and-fro motion, and vibration damper is used for suppressing this spring jump.Vibration damper is too soft, and vehicle body will jump up and down, and vibration damper will bring too large resistance too firmly, hinders spring normally to work.For general vibration damper, its damping is fixed, this has also determined that Designer can only get one between travelling comfort and motility, or choose the vibration damper that soft or hard is relatively compromised, and to allow a vehicle both comfortable, can have again certain motility, that just needs vibration damper automatically to regulate.But because traditional vibration damper lacks the function of adjusting self damping; therefore for the automobile that traditional shock absorber has been installed; the travelling comfort of automobile and motility are the two sides of contradiction; turn round and look at this and will lose that; although alleviate to a certain extent this contradiction by the adjustment meeting of hanging, also only just relax.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, a kind of adjustable electromagnetic shock absorber is proposed, can make by the electric current in electromagnetic coil is regulated, thereby accurately control the damping of vibration damper, make shock absorber adapt to current road conditions and driving demand, make automobile have travelling comfort and motility concurrently.
For achieving the above object, the utility model proposes a kind of adjustable electromagnetic shock absorber, comprise dust-proof cover, oil storage cylinder, clutch release slave cylinder, piston rod and electromagnetic piston, described dust-proof cover is installed on the top of oil storage cylinder, clutch release slave cylinder is installed in oil storage cylinder, the top of clutch release slave cylinder is provided with guide holder, guide holder top is provided with oil seal structure, described piston-rod end is positioned at clutch release slave cylinder through guide holder, described electromagnetic piston is installed on the end of piston rod, on electromagnetic piston, have some through holes, some electromagnetic coils are installed in electromagnetic piston, described oil storage cylinder adopts bottom valve to be connected with clutch release slave cylinder, magnetic flow liquid oil body is housed in described clutch release slave cylinder and oil storage cylinder.
As preferably, the upper end of described dust-proof cover is provided with upper bracket, and the lower end of oil storage cylinder is provided with undersetting, and upper end and the dust-proof cover of described piston rod are fixedly connected, and bearing makes the easier for installation, firm of vibration damper.
As preferably, in described electromagnetic piston all be distributed with 4 independently electromagnetic coils, the below of electromagnetic coil is provided with filter membrane, described bottom valve is positioned at the below of filter membrane, described bottom valve is provided with compression valve and recuperation valve.
As preferably, described magnetic flow liquid oil body contains ferrous compound particle, and the particle diameter of described ferrous compound particle is 15～20 μ m, and the aperture of described filter membrane is 3～10 μ m, and this suspension presents low viscous Newtonian fluid characteristic under zero magnetic field condition; And under strong magnetic field action, present the Bingham bulk properties of high viscosity, lazy flow, filter membrane can make magnetic flow liquid oil body freely pass through, but can not make ferrous compound particle pass through, ferrous compound particle is mainly present in the oil body in clutch release slave cylinder, keeps the magnetic flow liquid oil body in clutch release slave cylinder to there is good magnetic property.
The beneficial effects of the utility model: the utility model is by adopting electromagnetic piston, 4 independently electromagnetic coils are installed in electromagnetic piston, and the magnetic flow liquid oil body that installing contains ferrous compound particle in clutch release slave cylinder, this suspension presents low viscous Newtonian fluid characteristic under zero magnetic field condition; And under strong magnetic field action, present the Bingham bulk properties of high viscosity, lazy flow, therefore change self damping of vibration damper by controlling size of current in electromagnetic coil, change the hardness of damping, make shock absorber adapt to current road conditions and driving demand, make automobile have travelling comfort and motility concurrently.
