Abstract
The utility model discloses an inflatable bumper shock absorber director seal structure, it includes a hydraulic cylinder and piston rod, it holds sliding fit to have a director to be close to to aerify between hydro -cylinder inner wall and piston rod, stretching the end between gland and the piston rod, the director be equipped with an oil cup in, be equipped with the lubricated slot that accesss to piston rod and gland inner wall bottom the oil cup, the inner wall mid -mounting that contacts at director and piston rod has two at least these special sealing, install a guidance tape on this special the left side of sealing, install the type of Y for an axle circle on this special the right of sealing, install a dust ring at the director lateral surface with the oil cup department of correspondence between the piston rod. The utility model discloses have that the seal is good, piston motion is nimble, not fragile, not only makes driver and crew feel comfortable, can effectively improve bumper shock absorber life in addition.
Description
Technical field:
This utility model is that a kind of air filling type shock absorber guider being suitably mounted on vehicle be effectively improved intact stability seals structure.
Background technology:
Current automobile absorber has multiple, mainly there are hydraulic damper, air filling type shock absorber and adjustable damping formula amortisseur, hydraulic damper be move back and forth in hydraulic cylinder by piston, fluid along with flowing into another inner chamber from an inner chamber, orifice valve produces damping force and reaches the purpose of damping；Air filling type shock absorber is that the high pressure nitrogen by floating piston cylinder barrel one end compresses, and release process and the piston damping force that orifice valve produces in reciprocating motion carries out damping.This existing amortisseur, because design of Sealing Structure is unreasonable, poor sealing performance, causes motility and anti-wear performance poor, and stability in use is under some influence, and makes driver and crew not feel well, and the amortisseur life-span is low.
Summary of the invention:
The purpose of this utility model is to provide a kind of motility that can improve piston rod movement and wearability, it is ensured that a kind of air filling type shock absorber guider of vehicle operation stability seals structure.
nullThe technical solution of the utility model completes as follows，A kind of air filling type shock absorber guider seals structure，It includes a hydraulic jack and piston rod thereof，It is characterized in that: between oil cylinder inner wall and piston rod, be sliding combined with a guider near inflation end，The guider left end boss by oil cylinder exhaust ports is provided with a cushion collar，Guider inflation end oil cylinder outer wall there is a gland with threaded，The oil cylinder outer wall of the gland end of thread is provided with a locking nut，The right-hand member periphery of guider annular boss fixes between gland head inwall and oil cylinder end face，A lubricating cup it is provided with in the termination that guider reaches between gland and piston rod，It is provided with bottom lubricating cup and leads to piston rod and the lubricating channels of gland inwall，This special envelope of at least two is installed in the middle part of the guider inwall with plunger rod contacts，On the left side of this special envelope, one guidance tape is installed，On the right of this special envelope, one axle Y-shaped ring is installed，Lubricating cup corresponding position between guider lateral surface and piston rod is provided with a dust ring.The outer wall of guider is provided with O and back-up ring.
This utility model have good leak tightness, piston movement flexibly, be hardly damaged, not only make driver and crew feel comfortable, and amortisseur service life can be effectively improved.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
nullEmbodiment is described in detail in conjunction with accompanying drawing，It includes a hydraulic jack 2 and piston rod 1 thereof，Main improvements are to be sliding combined with a guider 4 near inflation end between oil cylinder inner wall and piston rod，The guider left end boss by oil cylinder exhaust ports is provided with a cushion collar 3，Guider inflation end oil cylinder outer wall there is a gland 8 with threaded，The oil cylinder outer wall of the gland end of thread is provided with a locking nut 7，The right-hand member periphery of guider annular boss fixes between gland head inwall and oil cylinder end face，A lubricating cup 10 it is provided with in the termination that guider reaches between gland and piston rod，The lubricating channels 9 leading to piston rod and gland inwall it is provided with bottom lubricating cup，This special envelope 13 of at least two is installed in the middle part of the guider inwall with plunger rod contacts，On the left side of this special envelope, one guidance tape 14 is installed，On the right of this special envelope, one axle Y-shaped ring 12 is installed，Lubricating cup corresponding position between guider and piston rod is provided with a dust ring 11.The outer wall of guider is provided with O 5 and back-up ring 6.Arranging O on guider, can prevent in-oil cylinder hydraulic oil seepage, back-up ring is damaged after being used for preventing O from once clamp-oning gap.Dust ring is set on guider and enters oil cylinder for preventing dust etc. to be attached to piston rod；Axle Y shape circle and this special envelope are used for preventing in-oil cylinder oil leakage；Guidance tape is used for preventing piston rod from being caused eccentric wear by lateral forces and guider generation friction, damages sealing；Guidance tape is because having self-lubricating property, the frictional force between piston rod and guide post can be reduced, after the lubricating channels arranged on guider injects grease, it is possible to reduce the frictional force between piston rod and guider further, too much grease side can be overflowed from the groove of guider opposite side；Use union (screwed)bonnet (UB to compress guider, and can prevent from getting loose with locking nut locking；Cushion collar is to prevent amortisseur from being damaged by excessive impulsive force, can improve, by above-mentioned improvement, motility, stability and the wearability that piston rod moves in oil cylinder, reaches to extend the service life of amortisseur.
