Abstract
The present invention relates to an automobile shock absorber with an oil groove sandwiched and guides connected between an upper oil seal and a lower oil seal. One guide is sheathed on the upper part of the inner wall of an outer oil cylinder, and the other guide is provided with an inclined soaking through hole communicated with an inner oil cylinder and the outer oil cylinder. The outer wall of the outer oil cylinder is fixed with a connecting plate, the middle of the outer oil cylinder is fixed with a spring tray, and a cylinder port of the outer oil cylinder is in screwed connection with a body-connecting seat. The lower oil seal is sheathed in a step shape in the body-connecting seat and is sheathed on a piston rod, and the two guides are fixed on a body-connecting seat sleeve of the upper part of the lower oil seal. The body-connecting seat of the upper parts of the two guides is provided with an annular lubricating oil cavity, the upper part of the annular lubricating oil cavity is the upper oil seal fixed in the body-connecting seat, and the upper part of the upper oil seal is an upper cover in screwed connection with the body-connecting seat. The present invention has the advantages of capability of reducing the abrasion of a piston, long service life, stable performance, good using effect and capability of being widely popularized and used.
Description
The present invention relates to a kind of vehicle shock absorber.
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 vehicle shock absorber that the purpose of this invention is to provide a kind of oil tight, long service life.
The objective of the invention is to realize by following structure: the present invention is a kind of vehicle shock absorber, on, following oil-sealing sleeve is sleeved on the piston rod, 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, fix connecting panel on the outer oil cylinder outer wall, fixing spring tray in the middle, on, accompany oil groove and guides between the following oil sealing, outer oil cylinder cylinder mouth is threaded with the disjunctor seat, suit down oil sealing in the disjunctor seat stepped appearance, and two guidess are fixed on down in the disjunctor seat on oil sealing top and put, and 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 the sealing of lubricant reservoir, prevents that all kinds of foreign material from entering, and 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 button 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.
