Abstract

The utility model discloses a double-valve spring shock absorber. The double-valve spring shock absorber comprises a piston rod, a working cylinder and an oil storage cylinder. The piston rod, the working cylinder and the oil storage cylinder are coaxially arranged. 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, a rebound valve and a flow valve. The top of the working cylinder is provided with a guide base and an oil seal. The top of the oil storage cylinder is provided with a dust cover. A spring is arranged at the bottom in the working cylinder. The bottom of the spring is provided with a magnet. The end portion of the piston rod is provided with a shoulder step. The dust cover is sleeved on the piston rod and abuts against the shoulder step. The upper portion and the lower portion of the working cylinder are respectively provided with filter screens. Compared with the conventional double-valve spring shock absorber, the double-valve spring shock absorber has following advantages: iron scrap can be effectively absorbed so that the abrasion problem of the working cylinder can be resolved; the shock absorber is simple in structure, longer in service lifetime and better in shock-absorbing effect.

Description

The bivalve spring damper
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 bivalve spring damper.
Background technique
Vibration damper is the necessary equipment of motor vehicle, its working principle is, when relative movement appearred in vibrations between vehicle body and vehicle bridge, the piston in vibration damper moved up and down, and the damping oil in the vibration damper clutch release slave cylinder flows in another chamber through different holes from a chamber repeatedly.Friction between hole wall and damping oil and the intermolecular interior friction of fluid at this moment forms damping force to vibrations, and making the thump Conversion of Energy is damping oil heat energy, then absorbed and be dispersed in atmosphere by vibration damper.Friction process can produce iron filings, is mingled in damping oil the aggravation fretting wear.Foreign impacts or vibrations are when too large, and piston moves up and down distance and speed aggravation, and the load that easily causes vibration damper to bear is excessive and lost efficacy.For this reason, the applicant has applied for the multiple-effect vibration damper before this, the piston rod, clutch release slave cylinder and the oil storage cylinder that comprise 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, rebound valve and flowing valve, and the top of clutch release slave cylinder is provided with guide holder and oil sealing, and the top of oil storage cylinder is provided with dust-proof cover, it is characterized in that the clutch release slave cylinder inner bottom part is provided with spring, the spring bottom is provided with magnet.Its advantage is damping oil to be kept clean the iron adsorption in damping oil, the wearing and tearing of reducing friction.But, in practical application, still there is defect, as fail effectively to solve because iron filings produce the problem that causes the clutch release slave cylinder wearing and tearing, working life is shorter etc.
The model utility content
The purpose of this utility model is to provide a kind of bivalve spring damper of new structure, and it can not only effectively adsorb the problem that iron filings solve the clutch release slave cylinder wearing and tearing, and simple in structure, longer service life, and damping effect is better.
for realizing this damping purpose, the technical solution of the utility model is: a kind of bivalve spring 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, 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, the clutch release slave cylinder inner bottom part is provided with spring, the spring bottom is provided with magnet, 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, described clutch release slave cylinder upper and lower is respectively arranged with filter screen.
As improvement of the present utility model, described piston rod is the inner hollow-core construction that is provided with vestibule, described piston rod vestibule is built-in with adjustable lever, and the bottom of described piston rod radially is provided with oil duct, and the two ends of described oil duct are connected conducting with described piston rod vestibule with the oil storage cylinder inner chamber respectively.
As improvement of the present utility model, described piston rod surface is covered with a metal film layer.
As improvement of the present utility model, described guide holder is provided with through hole.
The structural advantage of the utility model is: have additional on the one hand filter screen, can keep damping oil clean iron adsorption in vibration damper, avoid accelerating fretting wear because of iron filings, extend the life-span of vibration damper, make vibration damper that working state preferably be arranged.Adopt on the other hand shoulder rank on piston rod and locking element to realize fixing to dust-proof cover not there will be situation loosening or that come off, make fixing more stable to dust-proof cover, also improved the reliability under the vibration damper working state simultaneously.
The accompanying drawing explanation
Fig. 1 is the utility model embodiment's structural representation.
Wherein: 1. dust-proof cover, 2. piston rod, 3. guide holder, 4. clutch release slave cylinder, 5. flowing valve, 6. recuperation valve, 7. compression valve, 8. oil storage cylinder, 9. rebound valve, 10. spring, 11. magnet.
Embodiment
In conjunction with the embodiments the utility model is further illustrated with reference to the accompanying drawings.
As shown in Figure 1, a kind of bivalve spring damper, the piston rod, clutch release slave cylinder and the oil storage cylinder that comprise 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, 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, the clutch release slave cylinder inner bottom part is provided with spring, the spring bottom is provided with magnet, described piston rod end is provided with the shoulder rank, and described dust-proof cover is sheathed on piston rod and with these shoulder rank and offsets, and described clutch release slave cylinder upper and lower is respectively arranged with filter screen.Wherein, described piston rod is the inner hollow-core construction that is provided with vestibule, and described piston rod vestibule is built-in with adjustable lever, and the bottom of described piston rod radially is provided with oil duct, and the two ends of described oil duct are connected conducting with described piston rod vestibule with the oil storage cylinder inner chamber respectively.Described piston rod surface is covered with a metal film layer.Described guide holder is provided with through hole.
Though it is pointed out that above-described embodiment is to the utility model detailed text description of contrasting, these text descriptions are just to the simple description of the utility model mentality of designing, rather than to the restriction of the utility model thinking.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
