Abstract
The invention discloses a suspension double-buffering damper, which comprises a working cylinder and a liquid storage cylinder, wherein a piston is movably arranged in the working cylinder, and the piston is fixedly connected with a piston rod. The suspension double-buffering damper is characterized in that the middle of the working cylinder is fixedly provided with a fixing ring; the upper surface and the lower surface of the piston are fixedly provided with springs; the working cylinder consists of a first cylinder block and a second cylinder block, wherein the first cylinder block and the second cylinder block have different diameters; a transition section is arranged between the first cylinder block and the second cylinder block; the pipe body surface of the piston rod is provided with oil tanks which are arranged in a spiral line; the head part of the piston rod is provided with a buffer gear; the buffer gear comprises two sets of serial buffer cushions and buffer blocks. Compared with the prior art, the suspension double-buffering damper has the advantages of simple structure and easiness in production, the practical deformation amount of the piston can be effectively lowered, and the service life of the damper is prolonged.
Description
Technical field
The present invention relates to a kind of vehicular shock absorber improving stability in vehicle travel process, be specifically related to a kind of hovering double buffering vibration damper.
Background technique
Two-way function vibration damper is more and more popularized, the working principle of two-way function vibration damper is, from impact and the vibrations on road surface, made by the transmission of cylinder body piston move reciprocatingly relative to clutch release slave cylinder in clutch release slave cylinder, control the flowing of clutch release slave cylinder internal damping oil to realize damping shock absorption by compression valve and recuperation valve.When the impact in the external world with when shaking very large, the damping oil flow in clutch release slave cylinder is comparatively large, and the working load of vibration damper is comparatively large, the easy corrupted of vibration damper.I once applied for the patent of invention of a two-way function vibration damper by name before this, its technological scheme comprises the coaxial piston rod, clutch release slave cylinder and the oil storage cylinder that arrange, clutch release slave cylinder bottom is provided with compression valve and recuperation valve, the bottom of piston rod is provided with piston, piston is provided with rebound valve and flowing valve, the top of clutch release slave cylinder is provided with guide holder and oil sealing, the top of oil storage cylinder is provided with dust-proof cover, piston upper and lower surface is fixedly installed spring, the other end of spring is unsettled, and the spring of piston upper surface is around piston rod surrounding.The spring of piston lower surface be one with the spring of piston coaxial, or arrange around piston centre multiple, surround circle.Its advantage is by arranging spring in piston upper and lower surface, does not affect the normal cushioning effect of vibration damper, when foreign impacts or when shaking larger, prevents piston from moving up and down distance too large, avoids vibration damper serious wear even to cause losing efficacy.But still there is a distinct disadvantage, complex structure, and due to clutch release slave cylinder be cylinder type, connecting rod piston, when buffering hydraulic, can only carry out first-level buffer, therefore causes cushion effect inadequate, easily causes vehicle body strenuous vibration.
Summary of the invention
The object of the present invention is to provide a kind of hovering double buffering vibration damper of new structure, it effectively can not only reduce the amount of deformation of piston reality, extends the life-span of vibration damper, and structure is simple, is easy to produce.
For realizing this damping object, technological scheme of the present invention is: a kind of hovering double buffering vibration damper, comprise clutch release slave cylinder and liquid storage cylinder, piston is movably set with in described clutch release slave cylinder, piston is fixedly connected with piston rod, the middle part of described clutch release slave cylinder is fixedly installed a retaining ring, described piston upper and lower surface is fixedly installed spring, described working cylinder is made up of different the first cylinder body of diameter and the second cylinder body, changeover portion is provided with between first cylinder body and the second cylinder body, the pipe shaft surface of described piston rod is provided with the oil groove of helical row, the head of described piston rod is provided with damping mechanism, described damping mechanism comprises the cushion pad and buffer stopper that two covers are arranged in series.
As improvement of the present invention, between described clutch release slave cylinder and liquid storage cylinder, be provided with link, described piston rod is also provided with limiting stopper, between described link and limiting stopper, be provided with elastic device.
As improvement of the present invention, described piston rod is also provided with locking element, this locking element and dust-proof cover form location fit.
As improvement of the present invention, described clutch release slave cylinder upper and lower is respectively arranged with filter screen.
The structural advantage of the present invention is: the features such as clutch release slave cylinder is two-level oil cylinder's composition, and connecting rod piston, when buffering hydraulic, can carry out level 2 buffering, and cushion effect is comparatively large, not easily causes vehicle body strenuous vibration, simple and reasonable for structure.On the other hand by increasing elastic device, when automobile running is on the road surface of comparatively jolting, the piston rod of vibration damper can to the external movement of clutch release slave cylinder, thus pressure elasticity device, the recuperability of vibration damper is progressively increased by pressure elasticity device, reach absorbing vibrational energy, relax the effect of road shocks.In addition, be provided with the oil groove of helical row on the pipe shaft surface of piston rod, lubricant oil is fully expelled in the matching gap of piston rod and cylinder body, and lubrication effect is better, contributes to the working life extending piston rod, reduces the probability that vibration damper breaks down.
