Abstract
The utility model discloses a bidirectional buffer damper. The bidirectional buffer shock absorber comprises a piston rod, a working cylinder and a storage cylinder. The lower portion of the working cylinder is provided with a compression valve and a compensation valve. The lower portion of the piston rod is provided with a piston. The bidirectional buffer damper is characterized in that: the upper and lower surfaces of the piston are fixed with springs; the end portion of the piston rod is provided with a shoulder stair; a dust cover is sleeved on the piston rod and abuts against the shoulder stair; an oil seat in a flanging structure is arranged between a guider and the piston rod; the working cylinder body is composed of a first cylinder body and a second cylinder body in different diameters; and a transition section is arranged between the first cylinder body and the second cylinder body. Compared with the conventional bidirectional buffer damper, the conventional bidirectional buffer damper has is simple in structure and good in sealing; strenuous vibration of a car body is alleviated by carrying out secondary buffer; and therefore a damping effect is enhanced.
Description
Technical field
The utility model relates to a kind of vehicular shock absorber that improves stability in the Vehicle Driving Cycle process, is specifically related to a kind of bidirectional buffering vibration damper.
Background technique
The two-way function vibration damper is more and more popularized, the working principle of two-way function vibration damper is, impact and vibrations from road surface, transmission by cylinder body moves reciprocatingly piston with respect to clutch release slave cylinder in clutch release slave cylinder, by what compression valve and recuperation valve were controlled clutch release slave cylinder internal damping oil, flow to realize damping shock absorption.Very large the time, the damping oil flow in clutch release slave cylinder is larger when the impact in the external world and vibrations, and the working load of vibration damper is larger, the easy corrupted of vibration damper.I once applied for the utility model patent of a two-way function vibration damper by name before this, its technological scheme comprises piston rod, clutch release slave cylinder and the oil storage cylinder of coaxial setting, the 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, be fixedly installed spring on the piston upper and lower surface, the other end of spring is unsettled, and the spring of piston upper surface is around the piston rod surrounding.The spring of piston lower surface is a spring with piston coaxial, or arranges a plurality ofly around the piston center, surrounds circle.Its advantage is by in the piston upper and lower surface, spring being set, and does not affect the normal cushioning effect of vibration damper, when foreign impacts or vibrations, when larger, prevents that piston from moving up and down distance too large, avoids the vibration damper serious wear even to cause losing efficacy.But still have a distinct disadvantage, and complex structure, and because clutch release slave cylinder is cylinder type, connecting rod piston when buffering hydraulic, can only carry out first-level buffer, therefore causes cushion effect inadequate, easily causes the vehicle body strenuous vibration.
The model utility content
The purpose of this utility model is to provide a kind of bidirectional buffering vibration damper of new structure, and it is not only simple in structure, good airproof performance, and can carry out secondary buffer and alleviate the vehicle body strenuous vibration, strengthen damping effect.
for realizing this damping purpose, the technical solution of the utility model is: a kind of bidirectional buffering vibration damper, the piston rod that comprises coaxial setting, clutch release slave cylinder and oil storage cylinder, the clutch release slave cylinder bottom is provided with compression valve and recuperation valve, the bottom of piston rod is provided with piston, be fixedly installed spring on described piston upper and lower surface, described piston rod end is provided with the shoulder rank, described dust-proof cover is sheathed on piston rod and with these shoulder rank and offsets, be provided with the oil sealing of turnup structure between described guider and piston rod, described working cylinder is comprised of diameter different the first cylinder body and the second cylinder body, be provided with changeover portion between the first cylinder body and the second cylinder body.
As improvement of the present utility model, be provided with link between described clutch release slave cylinder and liquid storage cylinder, also be provided with limiting stopper on described piston rod, be provided with elastic device between described link and limiting stopper.
As improvement of the present utility model, also be provided with locking element on described piston rod, this locking element forms location with dust-proof cover and coordinates.
As improvement of the present utility model, described clutch release slave cylinder upper and lower is respectively arranged with filter screen.
The structural advantage of the utility model is: clutch release slave cylinder is the characteristics such as two-level oil cylinder forms, and connecting rod piston when buffering hydraulic, can carry out level 2 buffering, and cushion effect is larger, is difficult for causing the vehicle body strenuous vibration, and is simple and reasonable for structure.Oil sealing adopts turnup structure on the other hand, be sealed and matched with guider and oil storage cylinder, the sealing of vehicle shock absorber is improved, this turnup structure has increased the bearing capacity of vibration damper sealing part simultaneously, improve the internal pressure of bearing of vehicle shock absorber, thereby improved the durability of product.By architecture advances, when automobile running was on the road surface of comparatively jolting, the piston rod of vibration damper can be to the external movement of clutch release slave cylinder, thereby pressure elasticity device, progressively increase the recuperability of vibration damper by the pressure elasticity device, reach absorbing vibrational energy, relax the effect of road shocks.
