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 people's life is more and more tightr.Along with the raising of people to quality of life demand, requirement to car comfort is also more and more higher, people have designed the shock absorbing apparatus of a lot of automobiles for this reason, and as vibration damper, on automobile, mounting shock absorber is widely used with this technology of travelling comfort that improves driver.
Existing vibration damper, for example the applicant is at a kind of automobile absorber [application number: 201220506156.3 of application in 2012; Notice of authorization number: CN202971705U], the clutch release slave cylinder that comprises oil storage cylinder, guiding device, piston, piston rod and be arranged in oil storage cylinder forms, 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, can drive above-mentioned piston to slide up and down in clutch release slave cylinder in the time that piston rod is stressed.
In vibration damper when work of this kind of structure, when piston slides up and down, the pressure oil in clutch release slave cylinder enters in air-fuel mixture chamber by compression valve, or 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, in the time of stretching or compression work, only has the pressure oil of part to move in chamber at cylinder body, air-fuel mixture, and the heat of generation is all positioned at the inside of vibration damper, be difficult for heat radiation, radiating effect is poor.And the vibration damper of this kind of structure, only to vehicle, the effect of damping is played in upper and lower vibration, inoperative for inclination and " nodding " problem of vehicle.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, provide one to turn to anti-inclination vibration damper, pressure oil in this vibration damper is that one-way circulation flows, the rear higher pressure oil of temperature of acting is pasting the outermost madial wall of vibration damper and is flowing, good heat dissipation effect, but also improved the ability of the anti-inclination of vehicle or anti-" nodding ".
The purpose of this utility model can realize by following technical proposal: one turns to anti-inclination vibration damper, 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, on described guider, there is the opening that is 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 conductions, described base position is also provided with inertia valve, described inertia valve has the function that makes the bottom of outer shell and the bottom of clutch release slave cylinder and oil storage cylinder be interconnected or cut off.
Active chamber is divided into more than one epicoele and the cavity of resorption of one-way valve below one of one-way valve by one-way valve one, in the time that 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 is pasting outer shell, inertia valve and one-way valve two, and the pressure oil in oil storage cylinder also enters into by one-way valve two part that cavity of resorption reduces to supplement the rear volume of piston rod pull-out; In the time that 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 flow in oil storage cylinder by opening, the madial wall that is pasting outer shell, inertia valve.This piston lever of reducer is in the time stretching or compress, and pressure oil is all that one-way circulation flows, and reduces the quantity of one-way valve in vibration damper, simple in structure; 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 in the time that vehicle produces centrifugal force or excess acceleration, inertia valve is closed or part is closed, cut off pressure oil circulate or moment is reduced the flow of pressure oil, improve damping, produce great damping, greatly increase the suspension rate of one-sided or full car, increase the ability of the anti-inclination of vehicle or anti-" nodding ".
Turn in anti-inclination vibration damper in above-mentioned one, in described base, have installation cavity, above-mentioned inertia valve is positioned at installation cavity, and the center of the two side up and down of described base has respectively the oil through being connected with installation cavity.Inertia valve is positioned at installation cavity, this kind of space that utilizes rational in infrastructure, and compact structure, oil through all can be interconnected outer shell bottom and clutch release slave cylinder bottom, oil storage cylinder.
Turn in anti-inclination vibration damper in above-mentioned one, described inertia valve comprises valve rod, spool and a pair of spring, described valve rod is mutually vertical with piston rod, and the two ends of valve rod are fixed on base, described valve core housing is in the center of valve rod, described a pair of spring is enclosed within respectively the two ends of valve rod, and one end of every 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 of passing through for pressure oil at oil through place.
