Description
The present invention relates to a kind of vehicle shock absorber, accompany oil groove and the vehicle shock absorber that is connected guides in the middle of particularly a kind of upper and lower oil seals.
Junction at four wheels of automobile and forward and backward bridge is installed with snubber, prior oscillating damper is a welded structure, can only one-shot usage, it only is provided with one sealing member and a guide, owing to can produce the eccentric wear phenomenon after piston rod is stressed, cause the wearing and tearing of piston and piston rod, greatly reduce the service life of product, because piston rod is single oil sealing sealing, therefore various foreign material sting saturating oil sealing easily, produce wearing and tearing and leakage phenomenon, have reduced dumping force, piston rod weares and teares too early, has shortened the service life of shock absorber.
The purpose of this invention is to provide middle oil groove and the vehicle shock absorber that is connected guides of accompanying of a kind of upper and lower oil seals oil tight, long service life.
The objective of the invention is to realize by following structure: the present invention is for accompanying oil groove and the vehicle shock absorber that is connected guides in the middle of a kind of upper and lower oil seals, in the outer oil cylinder inner cylinder is installed, inner cylinder is communicated with bottom valve, bottom valve is fixed on the inner bottom part of outer oil cylinder, inner cylinder is installed with piston rod, it is gentle to the glue ring that upper cover of piston rod is being adorned spacing iron hoop, the piston rod front end is fixedly mounting piston, one guides is sleeved on outer oil cylinder inner wall top, have in the connection on one guides, the oblique oil through of outer oil cylinder, fixing connecting panel on the outer oil cylinder outer wall, fixing spring tray in the middle, outer oil cylinder cylinder mouth is threaded with the disjunctor seat, and the interior suit of stepped appearance down oil sealing in the disjunctor seat, and following oil-sealing sleeve is contained on the piston rod, two guidess are fixed on down in the disjunctor seat on oil sealing top and put, have annular lubricant reservoir on the disjunctor seat on two guides tops, its top is the last oil sealing that is fixed in the disjunctor seat, and the loam cake of the portion of sealing up for being threaded with the disjunctor seat oils.
The present invention by piston rod on inner cylinder, following motion, produce dumping force, play damping of vibrations, the present invention is on the basis of a guides, the concentricity that can guarantee piston that cooperates by two locating surfaces of two guidess and a guides, prevent that eccentric wear from producing, the wearing and tearing of piston rod have been reduced, prolonged the service life of piston, the dumping force that has guaranteed piston effectively exists, this cooperation can guarantee on the piston rod at last oil sealing simultaneously, right alignment in the following oil sealing prevents oil sealing, following oil sealed excessive abrasion, two guidess can also prevent the destruction of extraneous metal object to the cylinder seal performance.The structure of lubricant reservoir of the present invention is very necessary, and it is lubricated that it can supply with two guidess, prevents that two guidess, piston rod from overheatedly wearing and tearing, the scratch phenomenon.Last oil sealing can guarantee lubricant reservoir sealing, prevent that all kinds of foreign material from entering, loam cake plays and compresses oil sealing and be connected with thread forms with the disjunctor seat simultaneously." O " shape seal ring is that damped cylinder is sealed, and prevents damped cylinder leakage of oil, gas leakage.Fixing screw is contained in the athwartship plane of outer oil cylinder outer wall, prevents from that outer oil cylinder cylinder mouth is threaded to move back with the disjunctor seat to buckle phenomenon, plays positioning action.The present invention can reduce piston wear, long service life, stable performance, and result of use is good, can extensively promote the use of.
