Abstract
The invention discloses an inflatable type damper guider sealing structure. The inflatable type damper guider sealing structure comprises a hydraulic oil cylinder and a piston rod. A guider is arranged between the inner wall of the oil cylinder and the piston rod and close to the inflation end in a sliding fit mode. An oil cup is arranged in the end, extending between a pressing cover and the piston rod, of the guider. The bottom of the oil cup is provided with a lubrication trough leading to the piston rod and the inner wall of the pressing cover. At least two step seals are installed in the middle of the inner wall, making contact with the piston rod, of the guider. A guiding belt is arranged on the left of the step seals. A shaft Y-shaped ring is arranged on the right of the step seals. A dustproof ring is installed in the position, corresponding to the oil cup, between the outer side face of the guider and the piston rod. The inflatable type damper guider sealing structure has the advantages that the sealing property is good, a piston moves flexibly, damage is not liable to occur, a driver and a passenger feel comfortable, and the service life of a damper can be effectively prolonged.
Description
Technical field:
The present invention is a kind of air filling type shock absorber guider sealed structure being applicable to be arranged on vehicle and effectively improving vehicle stabilization.
Background technology:
Current automobile absorber has multiple, mainly contain oleo damper, air filling type shock absorber and adjustable damping formula vibroshock, oleo damper flows into another inner chamber by piston to-and-fro movement in hydraulic cylinder, fluid along with from an inner chamber, and orifice valve produces the object that damping force reaches damping; Air filling type shock absorber is that the high pressure nitrogen by floating piston cylinder cylinder one end compresses, and dispose procedure and the piston damping force that orifice valve produces in to-and-fro movement carries out damping. This kind of existing vibroshock, because design of Sealing Structure is unreasonable, poor sealing performance, causes handiness and wear resisting property poor, and stability in use is under some influence, and makes driver and crew feel uncomfortable, and the vibroshock life-span is low.
Summary of the invention:
It is an object of the invention to provide a kind of handiness and the wear resistance that can improve piston rod movement, ensure a kind of air filling type shock absorber guider sealed structure of vehicle operating stability.
The technical scheme of the present invention completes as follows, a kind of air filling type shock absorber guider sealed structure, it comprises a hydraulic ram 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 boss of guider left end by oil cylinder exhaust ports is provided with a buffering cover, inflate on end oil cylinder outer wall with the gland that has been threaded at guider, the oil cylinder outer wall of gland thread end is provided with a set nut, the right-hand member periphery of guider annular boss fixes between gland head inwall and oil cylinder end face, reach at guider and in the termination between gland and piston rod, it is provided with an oily cup, it is provided with, bottom oil cup, the lubricating channels leading to piston rod and gland inwall, at guider, at least two these spies seal with being provided with in the middle part of the inwall that piston rod contacts, a guiding band is installed on the left side of this special envelope, on the right of this special envelope, an axle Y-shaped ring is installed, oily cup corresponding position between guider outer side and piston rod is provided with a dustband.The outer wall of guider is provided with O and back-up ring.
The present invention has good leak tightness, piston motion flexibly, not easily damage, and not only makes driver and crew feel comfortable, and can effectively improve vibroshock work-ing life.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention.
Embodiment:
Embodiment is described by reference to the accompanying drawings in detail, it comprises a hydraulic ram 2 and piston rod 1 thereof, main improvements are sliding combined with a guider 4 near inflation end between oil cylinder inner wall and piston rod, the boss of guider left end by oil cylinder exhaust ports is provided with a buffering cover 3, inflate on end oil cylinder outer wall with the gland 8 that has been threaded at guider, the oil cylinder outer wall of gland thread end is provided with a set nut 7, the right-hand member periphery of guider annular boss fixes between gland head inwall and oil cylinder end face, reach at guider and in the termination between gland and piston rod, it is provided with an oily cup 10, it is provided with, bottom oil cup, the lubricating channels 9 leading to piston rod and gland inwall, at guider, at least two these spies seal 13 with being provided with in the middle part of the inwall that piston rod contacts, a guiding band 14 is installed on the left side of this special envelope, on the right of this special envelope, an axle Y-shaped ring 12 is installed, oily cup corresponding position between guider and piston rod is provided with a dustband 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 efficiency oil seepage, back-up ring is used for preventing O once damaged after squeezing gap. guider arranges dustband and enters oil cylinder for preventing dust powder etc. to be attached to piston rod, axle Y shape circle and this special envelope are used for preventing in-oil cylinder oil leakage, guiding band is used for preventing piston rod from causing inclined mill by lateral forces and guider generation friction, damages stopping property, guiding band is because having self-lubricating property, the frictional force between piston rod and tail rod can be reduced, after the lubricating channels arranged on guider injects lubricating grease, it is possible to reducing the frictional force between piston rod and guider further, too much lubricating grease side can be overflowed from the groove of another side of guider, adopt screw thread gland to compress guider, and pine can be prevented de-with set nut locking, buffering cover prevents vibroshock to be subject to excessive surging force and damage, and can improve, by above-mentioned improvement, handiness, stability and the wear resistance that piston rod move in oil cylinder, reaches the work-ing life of prolongation vibroshock.
