Description
Technical field
The utility model relates to the technical field of vibration damper, more particularly relates to the vibration damper that a kind of automobile is used.
Background technique
Vibration damper can both be seen on various automobiles, at present, mainly contain the hybrid vibration damper of hydraulic type vibration damper and oil gas on the market, they are mostly mainly by fuel tank, guide holder, piston and connecting rod constitute, the quality of its vibration damper quality can directly have influence on the travelling comfort of automobile, and hydraulic type vibration damper that occurs in the market and the hybrid vibration damper of oil gas they all to have a common shortcoming be exactly oily and air in same active chamber, because vibration damper is when work, its connecting rod and guide holder and oil sealing, rubbing action between piston and the clutch release slave cylinder, oil temperature in the vibration damper is constantly raise, gas and shock absorber oil in the vibration damper react under high temperature condition, shock absorber oil will produce emulsion, the damping property of vibration damper will be had a strong impact on, because the generation of shock absorber oil emulsion, increased the damping force of piston in clutch release slave cylinder, the reaction velocity of piston in clutch release slave cylinder will be slack-off, thereby make the earth-grasping force of automobile and handling all reduce greatly, because coexisting, its piston of air-cushion shock absorber in the market and air passageways in the clutch release slave cylinder, make effective vibration damping area of piston reduce greatly.
The model utility content
The purpose of this utility model provides a kind of simple in structure in order to solve the problems of the technologies described above exactly, low cost of manufacture, travelling comfort is good, the reaction velocity of piston is fast, effective vibration damping area of piston is big, can avoid shock absorber oil emulsion to occur, and can effectively improve the earth-grasping force of automobile and the Oil-gas Separation formula twin-tub vibration damper of handling.
The technical solution that the utility model adopts in order to solve the problems of the technologies described above is as follows:
Oil-gas Separation formula twin-tub vibration damper, it mainly is made of fuel tank, base, guiding device, piston, connecting rod, secondary fuel tank and the floating piston that is arranged in the secondary fuel tank, base is arranged on the opening of fuel tank one end, guiding device is arranged on the opening of the fuel tank the other end, connecting rod passes guiding device fixedlys connected with the piston in the fuel tank, described secondary fuel tank is connected with fuel tank, and offers air-filled pore on the secondary fuel tank between floating piston and the secondary fuel tank bottom.
Described fuel tank and secondary fuel tank link together by transport pipe is soft.
The base of described fuel tank is provided with the oil transportation hole, and transport pipe is connected with oil transportation hole on the base.
Described fuel tank and secondary fuel tank are fixed together by the connecting base that offers oil transportation channel.
The base of described fuel tank is provided with the oil transportation hole, and the oil transportation channel on the connecting base is connected with oil transportation hole on the base.
Described guiding device mainly is made of guide holder, lining and oil sealing, and lining and oil sealing are separately positioned on the guide holder inboard.
The inboard of described guide holder and the outside also are provided with seal ring.
The air-filled pore place that offers on the described secondary fuel tank is provided with valve.
Described floating piston is provided with seal arrangement.
Described seal arrangement is a seal ring.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is: simple in structure, low cost of manufacture, by increasing floating piston, just can very avoid the generation of vibration damper oil float phenomenon effectively, advantageously guaranteed the effectiveness in vibration suppression of vibration damper, it mainly is the maintenance and the maintenance of vibration damper for convenience that valve is set at the air-filled pore place again, by increasing a fuel tank again, just strengthen the working stroke of piston in fuel tank greatly, thereby improved the damping property of vibration damper greatly.
