Abstract
The utility model relates to a damping vibration damper for magnetic fluid with adjustable gas, which is composed of a guide sleeve, a coil, a pressing cover, a cylinder, a piston, a magnetic fluid and a bottom cover, wherein, the inner part of the cylinder is filled with gas and provided with a piston, the piston is fixed by the guide sleeve, the pressing cover is arranged below the guide sleeve, the coil is arranged between the guide sleeve and the pressing cover, a gap between the piston and the cylinder is full of the magnetic fluid, and the bottom of the cylinder is provided with the bottom cover. Through the control of the coil current, the damping force can be adjusted; so the vibration damper is an ideal damping adjustable vibration damper.
Description
The utility model is a kind of magnetic fluid adjustable gas damping shock absorber, is used for the vibration damping of device such as vehicle.Belong to mechanical device.
Adaptive transmission control realizes that the adjusting of damping can realize that generally one is for regulating the aperture of throttle orifice by two kinds of methods; Its two viscosity for the adjusting working solution, the also main aperture of external research based on the adjusting throttle orifice, and realize that with adjusting working solution viscosity the application of damping adjusting does not almost have.China only limits to study the ride control shock absorber of regulating the throttle orifice aperture, does not also drop into and uses.And the throttle orifice ride control shock absorber, because the aperture of throttle orifice needs mechanical mechanism to carry out, the regular hour is wanted in the action of actuator, thereby has prolonged the response time, makes comparatively fast furnishing optimum value of damping.In grade damping vibration attenuation is arranged, damping has very big step increment in the transient process of each damping stage, thereby make and shaken body and be subjected to " impact ", the action of actuator can produce mechanical friction, produces abrasive dust inevitably, to the working oil fluidity adverse effect can be arranged, cause that simultaneously oil liquid temperature raises, also produce noise, fluid sealing difficulty is easily leaked.
The purpose of this utility model is in order to overcome above-mentioned deficiency, utilize the principle of magnet fluid sealing gas, serve as working medium by gas, magnetic fluid as the resistance of shock absorber regulator solution, and electromagnet is installed on vibration damper, the action of a magnetic field that electromagnet produces changes magnetic intensity in regulator solution one magnetic fluid by the regulating magnet electric current, thereby make regulator solution that different bearing capacities be arranged, reach the purpose of regulating damping.
This magnetic fluid adjustable gas damping shock absorber, form by pilot sleeve, coil, gland, cylinder barrel, cavity, magnetic fluid and bottom, be filled with gas in the cylinder barrel, piston is housed in the cavity, piston is equipped with gland by the pilot sleeve orientation under the pilot sleeve, between incorgruous sleeve and gland coil is housed, be filled with magnetic fluid in the gap between piston and cylinder barrel, bottom is equipped with in the cylinder barrel bottom.
The damping of this magnetic fluid adjustable gas damping shock absorber is regulated by current of electromagnet, and response is exceedingly fast.Even the adjusting of grade damping is arranged, the switching " steadily " between level and the level can not produce " impact ", and the adjusting of damping is by controlling the electromagnet current realization, thereby has eliminated mechanical friction, has eliminated noise yet.
Concrete structure of the present utility model is provided by accompanying drawing 1.
Fig. 1 is a magnetic fluid adjustable gas damping shock absorber plan view.
Main structure is among the figure: pilot sleeve 1, coil 2, gland 3, cylinder barrel 4, cavity 5, piston 6, magnetic fluid 7, bottom 8, gap 9.
Below in conjunction with accompanying drawing the utility model is described in detail.
The utility model is made up of pilot sleeve 1, coil 2, gland 3, cylinder barrel 4, cavity 5, piston 6, magnetic fluid 7 and bottom 8, be filled with gas in the cylinder barrel, piston is housed in the cavity, piston is by the pilot sleeve orientation, under the pilot sleeve gland is housed, between incorgruous sleeve and gland coil is housed, be filled with magnetic fluid in the gap 9 between piston and cylinder barrel, magnetic fluid is able to seal clearance under the action of a magnetic field that coil produces, bottom is equipped with in the cylinder barrel bottom.During use vibration damper is connected in and shaken on the object, during body excited by earthquake, therefore piston produces motion, the volume increase and decrease of the upper and lower cavity of being separated by piston is opposite, and air pressure one falls one liter, produces pressure difference, the gap that magnetic fluid is regulated between pressure extent and piston and cylinder barrel is relevant, the gap is big, and pressure difference is little, and the gap is little, pressure difference is big, the size in gap is subjected to the magnetic fluid of the action of a magnetic field and regulates, and the power in magnetic field has realized so just that by the size control of coil current pressure difference is the purpose that damping is regulated.It is a kind of desirable ride control shock absorber.
