Description
Technical field
The invention belongs to technical field of automobile, relate to a kind of vibration damper, particularly three anti-inclination vibration dampers of self-adapting type.
Background technique
Along with improving constantly of people's living standard, along with the continuous progress of science and technology, automobile has become requisite instrument in modern's life, and the life of people is more and more tightr.Along with people are to the raising of quality of life demand, also more and more higher to the requirement of car comfort, people have devised the shock absorbing apparatus of a lot of automobile for this reason, and as vibration damper, on automobile, mounting shock absorber is widely used with this technology of travelling comfort improving driver.
Existing vibration damper, such as the applicant is at a kind of automobile absorber [application number: 201220506156.3 of application in 2012; Authorization Notice No.: CN202971705U], comprise oil storage cylinder, guiding device, piston, piston rod and be arranged on the clutch release slave cylinder formation in oil storage cylinder, guiding device is arranged on the top open part of oil storage cylinder, piston rod is fixedly connected with the piston in clutch release slave cylinder through guiding device, and above-mentioned piston can be driven when piston rod is stressed to slide up and down in clutch release slave cylinder.
When the vibration damper of this kind of structure works, when piston slides up and down, the pressure oil in clutch release slave cylinder is entered in air-fuel mixture chamber by compression valve, or the pressure oil in air-fuel mixture chamber enters in clutch release slave cylinder by recuperation valve, and the flow direction of pressure oil is two-way flow.The vibration damper of this kind of structure, only include oil storage cylinder and clutch release slave cylinder, it is dual-tube shock absorber, and owing to being bidirectional-movement, vibration damper is when stretching or compression work, and only have the pressure oil of part to move in chamber at cylinder body, air-fuel mixture, the heat of generation is all positioned at the inside of vibration damper, not easy heat radiation, radiating effect is poor.And the vibration damper of this kind of structure, only the effect of damping is played in the vibration upper and lower to vehicle, for the inclination of vehicle and " nodding " problem inoperative.
Summary of the invention
The object of the invention is for the above-mentioned problems in the prior art, provide a kind of three anti-inclination vibration dampers of self-adapting type, pressure oil in this vibration damper is one-way circulation flowing, the pressure oil that after acting, temperature is higher againsts the outermost madial wall flowing of vibration damper, good heat dissipation effect, but also improve vehicle anti-side and incline or the ability of anti-" nodding ".
Object of the present invention realizes by following technical proposal: a kind of three anti-inclination vibration dampers of self-adapting type, comprise oil storage cylinder, clutch release slave cylinder, piston rod, base and guider, described clutch release slave cylinder is arranged in oil storage cylinder, described guider is fixed on the top of oil storage cylinder and clutch release slave cylinder, described base is fixed on the bottom of oil storage cylinder and clutch release slave cylinder, the inner of described piston rod is positioned at the active chamber of clutch release slave cylinder, outer end is stretched out outside clutch release slave cylinder and is connected with outside load-bearing material, it is characterized in that, also comprise outer shell, above-mentioned oil storage cylinder is arranged in outer shell, described guider has the opening being communicated with clutch release slave cylinder top and outer shell top, the end of described piston rod the inner is provided with one-way valve one, the bottom of described clutch release slave cylinder is provided with one-way valve two, described one-way valve one is identical with the direction of one-way valve two one-way conduction, described base position is also provided with inertia valve, described inertia valve has the function making the bottom of the bottom of outer shell and clutch release slave cylinder and oil storage cylinder be interconnected or cut off.
Active chamber is divided into the epicoele of one-way valve more than one and the cavity of resorption of one-way valve less than one by one-way valve one, when piston rod moves up, one-way valve one is closed, one-way valve two is opened, pressure oil in epicoele enters into cavity of resorption by opening, the madial wall that against outer shell, inertia valve and one-way valve two, and the pressure oil in oil storage cylinder also enters into cavity of resorption with the part of volume minimizing after supplementary piston rod pull-out by one-way valve two; When piston rod moves down, one-way valve one is opened, one-way valve two is closed, pressure oil in cavity of resorption enters into epicoele by one-way valve one, because piston rod enters, the volume that piston rod is positioned at active chamber increases, and the pressure oil in epicoele is flow in oil storage cylinder by opening, the madial wall that against outer shell, inertia valve.This piston lever of reducer is when stretching or compress, and pressure oil is all one-way circulation flowing, and reduce the quantity of one-way valve in vibration damper, structure is simple; Pressure oil in clutch release slave cylinder after acting intensification moves along the madial wall of outer shell all the time, good heat dissipation effect, long service life.And when vehicle produces centrifugal force or excess acceleration time, inertia valve is closed or part is closed, cut off the flow circulating or reduce instantaneously pressure oil of pressure oil, improve damping, produce great damping, greatly increase the suspension rate of one-sided or full car, increase the ability that vehicle anti-side is inclined or resisted " nodding ".
In above-mentioned three anti-inclination vibration dampers of self-adapting type, have installation cavity in described base, above-mentioned inertia valve is positioned at installation cavity, and the center of the two side up and down of described base has the oil through be connected with installation cavity respectively.Inertia valve is positioned at installation cavity, and this kind rational in infrastructure utilizes space, compact structure, and oil through makes outer shell bottom and clutch release slave cylinder bottom, oil storage cylinder all can be interconnected.
In above-mentioned three anti-inclination vibration dampers of self-adapting type, described inertia valve comprises valve rod, spool and a pair spring, described valve rod and piston rod are mutually vertical, and the two ends of valve rod are fixed on base, described valve core housing is in the center of valve rod, a pair described spring is enclosed within the two ends of valve rod respectively, and one end of every root spring is all resisted against on spool, the other end is all resisted against on base, the upper surface of described spool and lower surface fit with the madial wall of installation cavity respectively, and described spool and base have the gap passed through for pressure oil at oil through place.
