Abstract
The utility model relates to a shock damper, which is provided with a liquid storage barrel, an oil cylinder, a piston, a piston rod, a bottom valve and an oil seal guide sleeve, wherein the inner side of the oil seal guide sleeve is pressed with an antifriction lining and a reinforced oil seal; a liquid containing space is arranged between the end surface of the antifriction lining of the oil seal guide sleeve and a lip of the reinforced oil seal; the oil seal guide sleeve is evenly distributed with a plurality of overflow holes which are communicated with the liquid containing space and the liquid storage barrel; the liquid containing space buffers and reduce the impact of high-pressure liquid stream to the lip of the reinforced oil seal. The utility model effectively protects oil sealing and avoids leakage, has the advantage of long service life and improves the technical performance of a shock absorber.
Description
Technical field:
The utility model relates to a kind of auto parts machinery, is specifically related to a kind of automobile absorber.
Background technique:
Automotive industry is a mainstay of the national economy industry, and the production of auto parts machinery will enter the blowout phase, and the luxury bus vibration damper production domesticization of introduction is an inexorable trend.The hydraulic damper that structure is fairly perfect be bitubular double-action, four valves, two hole structures, but its outside framework oil seal lip of these hydraulic damper is subjected to the rigid impact of high pressure liquid stream, and aging fast, seepage is serious, influences working life and technical performance.
Summary of the invention:
Technical problem to be solved in the utility model is: solve existing automobile hydraulic vibration damper outside framework oil seal lip be subjected to the rigid impact of high pressure liquid stream, aging fast, seepage is serious, the problem that influences working life and technical performance; And provide a kind of can reduce high pressure liquid stream to the impact of oil seal lip, alleviate oil sealing wear out, avoid seepage, the novel damping device of the performance that increases the service life, develops skill.
The technical solution adopted in the utility model is: this novel damping device suit oil cylinder in surge drum, piston set and piston rod in the oil cylinder, the oil cylinder two ends are installed bottom valve and oil sealing guide sleeve respectively, bottom valve is provided with compression valve and recuperation valve, piston is provided with rebuilt valve and flowing valve, be pressed into anti-friction bush and outside framework oil seal in the oil sealing guide sleeve, leave certain distance between anti-friction bush end face in the oil sealing guide sleeve and the outside framework oil seal lip, have one and hold liquid space, uniform a plurality of overflow holes on the oil sealing guide sleeve, overflow hole two ends are communicated with respectively and hold liquid space and surge drum inner chamber.
The utility model, is brought in constant renewal on structural design as the oil sealing guide sleeve for the direct vital part that influences vibration damper performance, life-span.The damping force of vibration damper changes along with distance, speed, time, variation of temperature, and the speed that piston rod pumps changes to maximum by zero, changes to zero by maximum again, is bearing the effect of alternate load.Because the road conditions of vehicle driving are not good, when the vibration damper vibration velocity was maximum, high pressure liquid stream was very big to the impact force of oil seal lip.For reducing to impact, the utility model between the lining cover end, leaves certain distance at oil seal lip, has bigger appearance liquid space, reduce high pressure liquid stream speed and pressure after overflow hole enters surge drum, replenish in-oil cylinder oil mass and oil consumption, eliminate foam and oxidation.This appearance liquid space is a kind of buffer for liquid flow impact, has alleviated the impact of high pressure liquid stream to oil seal lip, has protected outside framework oil seal, has prolonged working life, has avoided the quick aging and the seepage of oil sealing, has improved the technical performance of vibration damper.The utility model is simple in structure, and is reasonable in design, solved the technical barrier of the easy seepage of hydraulic damper, make the imported auto domestic part, having reduced cost, improved the competitive ability of product on market, is a product that fills the domestic gaps, through showing the merit test, speed characteristics, temperature characteristic test, endurance test, functional, every technical order is all above national sector standard, and is basic identical with import parts.

Embodiment:
Referring to Fig. 1, Fig. 2, this novel damping device suit oil cylinder 11 in surge drum 10, piston set 4 and piston rod 9 in the oil cylinder 11, oil cylinder 11 two ends are installed bottom valve 1 and oil sealing guide sleeve 7 respectively, bottom valve 1 is provided with compression valve 2, has the normal open throttling pore, and compression valve 2 is normally closed.Also be provided with recuperation valve 3 on the bottom valve 1, recuperation valve 3 also is normally closed.Piston 4 is provided with rebuilt valve 5, has the normal open throttling pore, and rebuilt valve 5 is normally closed.Also be provided with flowing valve 6 on the piston 4, flowing valve 6 is normally closed.Be pressed into anti-friction bush 12 and outside framework oil seal 8 in the oil sealing guide sleeve 7, and get out 6 overflow apertures and communicate with surge drum 10, in the oil cylinder 11 high-pressure spray is arranged, connect surge drum outward and contain low pressure oil, piston rod 9 connects pistons 4, installing ring, dust cover.
Referring to Fig. 2, be pressed into anti-friction bush 12 and outside framework oil seal 8 in the oil sealing guide sleeve 7, leave certain distance between anti-friction bush 12 end faces and outside framework oil seal 8 lips, have one and hold liquid space 13, uniform 6 overflow apertures 14 on the oil sealing guide sleeve 7, overflow hole 14 1 ends are communicated with and hold liquid space 13, and the overflow hole the other end is communicated with surge drum 10 inner chambers, and oil sealing guide sleeve 7 terminations also are fixedly connected with seal plug 15.
Referring to Fig. 1, when restoring stroke, piston rod 9 moves to right, and oil cylinder 11 epicoele oil pressure increase, fluid enters cavity of resorption by the normal open throttling pore on the rebuilt valve during low speed, the high pressure oil of epicoele is opened rebuilt valve 5 during high speed, enters cavity of resorption, and cavity space is little on the oil cylinder, cavity of resorption is big, speed increases and forms vacuum, and recuperation valve 3 is opened, and the oil in the surge drum is full of cavity of resorption.During compression stroke, piston rod moves to left, and the oil of oil cylinder 11 cavity of resorptions is closed rebuilt valve 5, pushes flowing valve 6 open and enters epicoele, and this moment, the oil of cavity of resorption was closed recuperation valve 3.During low speed, fluid enters surge drum by the normal open throttling pore on the compression valve 2.Along with the increase of speed, high pressure oil is opened compression valve 2, enters in the surge drum, works successively.
