Abstract
The utility model discloses an oil seal device provided with a guider for a shock absorber, which pertains to sealing device and comprises a shell, a supporting shaft, a shell cap and an oil seal packing, wherein a guiding ring is sheathed on the supporting shaft in the shell, a guiding lining is additionally arranged in an annular gap between the guiding ring and the supporting shaft, an oil retainer is arranged at the outer end of the guiding lining, a framework oil seal is pressed at the outer end of the guiding ring, and the oil seal packing is embedded in an annular gap between the annular inner side of the framework oil seal and the supporting shaft. The oil seal device provided with the guider has simple structure and low cost, and is reasonably designed; and the oil retainer can prevent excessive hydraulic oil from impacting the oil seal, thus greatly alleviating aging and deformation of the oil seal, further guaranteeing the performances and various technical requirements of the shock absorber, enabling the performances of the shock absorber to be more stable, improving the quality and prolonging the service life of the shock absorber, and avoiding the phenomenon of unstable performances, reduced service life and the like of the shock absorber of the original design caused by leakage.
Description
Technical field
The utility model belongs to seal arrangement, particularly relates to a kind of shock absorber oil seal apparatus of tape guide device.
Background technique
Vibration damper is in restoring compression stroke, the active chamber internal pressure increases, because in the oil sealing and director assembly structure of vibration damper complement, guide bush and connecting rod have certain matching gap, compression recovery process mesohigh fluid directly impacts oil seal lip by this gap, the oily conductance of High Temperature High Pressure causes the aging distortion of rubber oil sea lip, reduces the oil sealing life-span, causes the oil sealing leakage of oil.
Summary of the invention
The utility model is intended to overcome the deficiencies in the prior art, and a kind of shock absorber oil seal apparatus of tape guide device is provided.
The shock absorber oil seal apparatus of tape guide device of the present utility model, constitute by housing, back shaft, shell cap and oil sealing packing, on the back shaft in housing suit guide ring, in the annular space of guide ring and back shaft, installed guide bush additional, outer end at guide bush is provided with flinger ring, outer end at guide ring is pressed with outside framework oil seal, inlay card oil sealing packing between the annular space of and back shaft inboard at the ring of outside framework oil seal.
As further improvement of the utility model, described flinger ring is to make with polytetrafluoroethylmaterial material.
The shock absorber oil seal apparatus of tape guide device of the present utility model, simple in structure, reasonable in design, cost is low, the structural design of flinger ring can prevent too much hydraulic oil bump oil sealing, reduce the aging metaboly of oil sealing greatly, thereby guaranteed performance and every technical requirements of vibration damper.Make its performance more stable, improved the quality and the working life of vibration damper.Avoid in the former design vibration damper unstable properties that causes owing to leaking, reduced phenomenons such as working life.
Description of drawings
Figure of description is the structural representation of the shock absorber oil seal apparatus of the utility model tape guide device.
Embodiment
The shock absorber oil seal apparatus of tape guide device of the present utility model, constitute by housing 1, back shaft 2, shell cap 3 and oil sealing packing 4, on the back shaft 2 in housing 1 suit guide ring 5, in the annular space of guide ring 5 and back shaft 2, installed guide bush 6 additional, be provided with flinger ring 7 in the outer end of guide bush 6, be pressed with outside framework oil seal 8 in the outer end of guide ring 5, inlay card oil sealing packing 4 between the annular space of and back shaft 2 inboard at the ring of outside framework oil seal 8.
The utility model adds a ring-type and keeps off oily element-flinger ring between guide bush and guider, the employing polytetrafluoroethylmaterial material is made, it has wear resistance and very little friction ractor preferably, and adopt interference fit between the connecting rod, the high temperature high pressure oil stream that comes out from guide bush and connecting rod is stoped by flinger ring, have only the gap of a small amount of fluid from flinger ring and lining and guider, through reaching the oil seal lip place after turning to for three times again, the throttling of oil liquid pressure this moment reduces, and oil mass seldom, can't directly impact oil seal lip, improve the oil sealing operating conditions, thereby improve the oil sealing life-span.Reduce the leakage of valve system simultaneously, increased the working pressure in the active chamber, guaranteed high turn of speed value, damping force is stable, and the plentiful slyness of indicator diagram has strengthened effectiveness in vibration suppression, improves its stationarity and well-formedness.
