Aiming at solving a problem that the conventional automobile shock absorber easily leaks oil, the utility model provides a self-tightening oil seal shock absorption assembly. The shock absorption assembly mainly comprises two sleeved cylinders and piston rods which can move along axial directions of the cylinders, wherein an inner barrel cavity is a working cavity, and a cavity formed between an inner barrel and an outer barrel is an oil storage cavity; the working cavity is divided into an upper cavity and a lower cavity; the upper cavity and the lower cavity are softly separated through a circulation resetting valve component; the piston rods move in the upper cavity along the axial direction in a reciprocating manner; the bottom of the working cavity and the bottom of the oil storage cavity are softly sealed by compensation compression valve components; and self-tightening oil seal parts are arranged on the top of the working cavity and the top of the oil storage cavity and comprise ship-type pressing blocks, rectangular pressing blocks arranged in the ship-type pressing blocks and flat pressing blocks positioned below the ship-type pressing blocks. Therefore, the durability of the shock absorber is improved, and the shock absorber can be used safely for a long time.
Description
Technical field
The utility model relates to automotive field, particularly relates to the auto parts machinery field, relates to the automobile shock assembly more specifically.
Background technique
The structure of vibration damper is that the piston rod that has piston inserts in the tube, in tube, is full of oil.Throttle orifice is arranged on the piston, make that the oil in two-part space that is separated by piston can complement each other.Damping produces during through throttle orifice at the oil with viscosity, and throttle orifice is more little, and damping force is big more, and the viscosity of oil is big more, and damping force is big more.If the throttle orifice size is constant, when the vibration damper operating rate was fast, the absorption of affects impact was crossed in damping.Therefore, in the outlet port of throttle orifice a discoid leaf spring valve is set, when pressure became big, valve was backed down, and it is big that the throttle orifice aperture becomes, and damping diminishes.Because piston is a bidirectional-movement, so in the both sides of piston the leaf spring valve is housed all, is called compression valve and rebound valve respectively.
Vibration damper can be divided into double barreled and monotubular formula by its structure.Double barreled is meant that vibration damper has inside and outside two tubes, and piston moves in inner core, because the entering and the extraction of piston rod, the volume of oil increases and contraction thereupon in the inner core, therefore will be through exchanging the balance of keeping oil in the inner core with urceolus.So four valves will be arranged in the dual-tube shock absorber, promptly two throttle valve on piston above-mentioned, be contained in the flowing valve and the recuperation valve of the completion exchange interaction between the inner/outer tube in addition.
Move nearly vehicle body at automotive wheel, vibration damper is by compression the time, and this moment, the vibration damper inner carrier moved down.The volume reducing of piston lower chambers, oil pressure raise, and the fluid flowing valve of flowing through flows to the chamber (epicoele) above the piston.Epicoele is by piston rod a part of space that accounted for, thereby the volume that reduces less than cavity of resorption of the volume that increases of epicoele, so a part of fluid is just pushed compression valve open, flows back to oil storage cylinder.These valves form the damping force that suspension moves by compression to the saving of oil.Away from vehicle body, vibration damper is stretched vibration damper at wheel, and at this moment the piston of vibration damper moves up.The piston upper chamber oil pressure raises, and flowing valve is closed, and the fluid in the epicoele is pushed rebound valve open and flowed into cavity of resorption.Because the existence of piston rod, the fluid that comes from epicoele stream is not enough to be full of the volume that cavity of resorption increases, and instigator's cavity of resorption produces a degree of vacuum, and at this moment the fluid in the oil storage cylinder is pushed recuperation valve open and flow to cavity of resorption and replenish.Because the throttling action of these valves, therefore play damping function when doing stretching exercise to being suspended in.
Since the rigidity of rebound valve spring and pretightening force design greater than compression valve, under same pressure effect, rebound valve and corresponding normal open slit and passage section amass summation less than compression valve and corresponding normal open slit channel cross-sectional area summation.This makes damping force that the extension stroke of vibration damper produces greater than the damping force of compression stroke, reaches the requirement of rapid damping.
Therefore, fluid is decisive role for the damping effect of damping assembly, but wearing out owing to accessories such as oil seal washer or packing rings; And vibration damper is aging; Vibration damper often is easy to generate the phenomenon of leakage of oil in use for some time, and the lighter influences the comfortable feel of driving and taking, weight person's generation that possibly cause the accident; Therefore find a kind of vibration damper of not easy oil leakage to become auto parts machinery manufacturing field, particularly vibration damper manufacturing field problem demanding prompt solution.
Summary of the invention
The utility model is to the problem of the easy leakage of oil of present automobile absorber; A kind of self-tightening oil seal damping assembly is provided; Described damping assembly is mainly by the cylinder of two fits and can form along the piston rod of cylinder axial motion; Said inner core cavity is that the cavity that forms between active chamber, inner core and the urceolus is an oil storage chamber; Said active chamber is divided into upper cavity and lower chamber, and through circulation rebuilt valve soft separating of assembly, said piston rod is to-and-fro motion vertically in upper cavity between said upper cavity and the lower chamber; The bottom of said active chamber and oil storage chamber is through the soft sealing of compensation compression valve assembly; The top of said active chamber and oil storage chamber is provided with the self-tightening oil seal parts, the flat briquetting that said self-tightening oil seal parts comprise ship type briquetting, are positioned over the rectangle briquetting in the ship type briquetting and are positioned at ship type briquetting below.
As further improvement, also include connecting ring, said connecting ring comprises connecting ring and following connecting ring, is individually fixed in the top and the urceolus bottom of piston rod.
As improvement further, ring and outer shroud in said connecting ring comprises are provided with resilient infill between said interior ring and the outer shroud.
Owing in the utility model, increased this member of self-tightening oil seal parts; And further disclose the flat briquetting that said self-tightening oil seal parts comprise ship type briquetting, are positioned over the rectangle briquetting in the ship type briquetting and are positioned at ship type briquetting below, the cooperation through ship type briquetting and rectangle briquetting has improved encapsulation; Because the two ends of ship type briquetting are protruding; So guarantee in use,, also do not influence sealing effect even small vibrations or fluctuation are arranged.So can guarantee after the oil-proof or permanent use of damping assembly oil-proof basically, thereby improved the durability of vibration damper, guaranteed the use that vibration damper is permanent, safe.
