Abstract
The utility model discloses a sealing device for an inflatable shock absorber for vehicles, which comprises a guide holder and an oil seal assembly composed of an oil seal body, oil seal springs and oil seal frames, wherein the root on the primary lip opening of the oil seal body is provided with a seal washer connected with the oil seal body into a whole, and the seal washer makes the oil seal assembly hermetically matched with the guide holder. When the shock absorber is static or a connecting rod is compressed, the seal washer divides a liquid receiver and a working cylinder into two mutually isolated spaces in the position of the guide holder, so gas in the liquid receiver can not enter the working cylinder. At the same time, when the connecting rod is static, the gas in the liquid receiver can not enter the working cylinder and the oil liquid in the working cylinder can not enter the liquid receiver. The equal height state of the oil liquid in the liquid receiver and the working cylinder of the shock absorber can be avoided thoroughly; the idle course state of the shock absorber, which appears in the initial stage, can be eliminated for improving the comfort in vehicle running.
Description
Technical field
The utility model relates to a kind of automobile-used gas-filled shock absorber, specifically relates to the oil-sealing arrangement of automobile-used gas-filled shock absorber.
Background technique
Automobile-used gas-filled shock absorber is along with the development of automobile industry is used more and morely, the seal arrangement of conventional automobile-used gas-filled shock absorber comprises by the oil sealing body, oil seal spring, oil seal assembly and guide holder that oil tight skeleton is formed, this oil seal assembly is that main lip is held connecting rod tightly by the active force of oil seal spring, form motive sealing, it between connecting rod and the guide holder Spielpassung, when vibration damper is static, the very easy gap location between connecting rod and guide holder of gas in the vibration damper surge drum enters clutch release slave cylinder, and the fluid in the clutch release slave cylinder also enters surge drum from gap location easily, so often cause the air pressure in surge drum and the clutch release slave cylinder to equate, and then make vibration damper fluid high state such as in surge drum and clutch release slave cylinder, be in, cause the vehicle launch initial operating stage idle running to occur, can not form damping or produce abnormal sound, influence travelling comfort by bus.With regard to its basic reason, be not take any means to stop the gas in the vibration damper surge drum in clutch release slave cylinder, to flow at the guide holder place.
The model utility content
The utility model aims to provide a kind of seal arrangement of automobile-used gas-filled shock absorber, and the sealing device can effectively stop gas the flowing in clutch release slave cylinder in the vibration damper surge drum at the guide holder place.
The purpose of this utility model is achieved in that
The seal arrangement of automobile-used gas-filled shock absorber, comprise oil seal assembly and the guide holder formed by oil sealing body, oil seal spring, oil tight skeleton, wherein be provided with and the oil sealing body seal washer that fuses at the root of oil sealing body master lip, the sealing packing ring is oil seal assembly and guide holder and is sealed and matched, during the compression of static or connecting rod, the sealing packing ring is divided into two spaces that isolate mutually with surge drum and clutch release slave cylinder in guide holder punishment when vibration damper.
Because the utility model is provided with seal washer at the root of oil sealing body master lip, after assembling automobile-used gas-filled shock absorber, the sealing packing ring is oil seal assembly and guide holder and is sealed and matched, when connecting rod during at extensional motion, clutch release slave cylinder upper end part fluid backs down seal washer by connecting rod and guide holder, enters surge drum by the spill port that is arranged on the guide holder; And when connecting rod compresses, fluid in the clutch release slave cylinder enters surge drum, the surge drum oil mass increases, air pressure strengthens, seal washer is pressed on guide holder under the effect of pressure, surge drum and clutch release slave cylinder are divided into two spaces that isolate mutually in guide holder punishment, make the gas in the surge drum can not enter clutch release slave cylinder; Simultaneously when connecting rod is static, gas in the surge drum can not enter clutch release slave cylinder, fluid in the clutch release slave cylinder can not enter surge drum, high state generations such as vibration damper fluid is in have thoroughly been stopped in surge drum and clutch release slave cylinder, eliminate the idle running situation of vibration damper initial stage appearance, improved the travelling comfort of vehicle operating.
