Abstract

The utility model relates to an air filled double-piston shock absorber, which comprises a piston and connecting rod assembly and a cylinder barrel, wherein one end of the piston and connecting rod assembly is provided with a connecting bolt; the other end of the piston and connecting rod assembly orderly passes through an oil seal seat and an oil seal, is connected with an oil piston, and is fixed by a nut; the inner side of the cylinder barrel is provided with an air piston; the air piston and the inner wall of the cylinder barrel are formed into a compressed air cavity; an oil piston non-rod cavity is formed between the oil piston and the air piston; an oil piston rod cavity is formed between the oil piston and the oil seal; the oil piston is provided with a throttling groove. Because a lower cavity is filled with compressed air with high air pressure, the utility model makes an operating cavity of a shock absorber comprising the oil piston non-rod cavity and the oil piston rod cavity always filled with sufficient oil liquid. Therefore, an operating position can not be limited by an installing angle any longer. The utility model provides a condition for more compact design of the air filled double-piston shock absorber, has the advantages of stable resistance variation, no rigid impact of internal component and long service life of the absorber, and people on vehicles feel more comfortable.

Description

Specification gas-filled type double-piston vibration damper
Technical field
The utility model relates to a kind of vibration damper, especially a kind of gas-filled type double-piston vibration damper.
Background technique
The double-barrel structure of clutch release slave cylinder, outer oil storage cylinder, bottom repairing has determined its setting angle on vehicle to obtain considerable restraint in the traditional shock absorber, during work, if the relative vertical deflection angle of piston rod is excessive, because of inhaling sky, interior clutch release slave cylinder can not get in time replenishing of outer oil storage cylinder inner fluid and causes operational failure in the time of will causing piston motion.The traditional shock absorber structures shape product because the defective that the recovery resistance transition that inner shock-absorbing joint stream unit frequency of okperation hysteresis piston thick stick motion frequency produces is not sufficiently oily.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of rational in infrastructure, two air-chamber pattern arresters that using effect is good are provided.
The utility model solves the technological scheme that its technical problem adopts: this gas-filled type double-piston vibration damper, comprise piston rod part and cylinder barrel, piston rod part one end is provided with connecting bolt, and the other end passes oil sealing base successively, oil sealing is connected with oily piston, and fixes by nut; Be provided with the gas piston in cylinder barrel, gas piston and inner wall of cylinder form the compression air cavity, form oily piston rodless cavity between the gentle piston of oily piston, form oily piston rod chamber between oily piston and the oil sealing, have throttling groove on the oily piston.
The effect that the utility model is useful is: this product is because cavity of resorption is filled with the very high pressurized gas of air pressure, the vibration damper active chamber is comprised remain sufficient fluid in oily piston rod chamber and the Wu Gang chamber, thereby make the working position limited by setting angle, the compacter condition that provides of this position design of car is provided.The traditional shock absorber structures shape product because the defective that the recovery resistance transition that inner shock-absorbing joint stream unit frequency of okperation hysteresis piston thick stick motion frequency produces is not sufficiently oily.This product structure has just in time remedied this deficiency, show that the merit test shows its line smoothing, full, thereby change in resistance is steady, and inner member does not have rigid impulse, thereby has prolonged the vibration damper operating life, and it is more comfortable that the people on the car also feels.
Description of drawings
Fig. 1 is that the utility model master looks the sectional structure schematic representation;
Description of reference numerals: piston rod part 1, buffer ring 2, end cap 3, circlip 4, first O-ring seals 5, oil sealing base 6, cylinder barrel 7, gas piston 8, second O-ring seals 9, suspension ring link 10, attachment hole 11, nut 12, oil sealing 13, oily piston rod chamber 14, oil piston 15, throttling groove 16, packing ring 17, oil piston rodless cavity 18, compression air cavity 19, cushion collar 20.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
This gas-filled type double-piston vibration damper comprises piston rod part 1 and cylinder barrel 7, and piston rod part 1 one ends are provided with connecting bolt, and cylinder barrel 7 peripheral hardwares are useful on dust-tight end cap 3, and piston rod part 1 is provided with buffer ring 2 stretching out on the end of end cap 3.The other end of piston rod part 1 passes oil sealing base 6 successively, oil sealing 13 is connected with oily piston 15, and fixes by packing ring 17, nut 12; In cylinder barrel 7, be provided with gas piston 8, gas piston 8 forms compression air cavity 19 with cylinder barrel 7 inwalls, forms oily piston rodless cavity 18 between the oily piston 15 gentle pistons 8, forms oily piston rod chamber 14 between oily piston 15 and the oil sealing 13, oil sealing 13 is provided with cushion collar 20, has throttling groove 16 on the oily piston 15.Described cylinder barrel 7 opposite sides are connected with suspension ring link 10, have the attachment hole 11 that is used to connect suspension ring on the suspension ring link 10.Have seal groove on the gas piston 8, between seal groove and cylinder barrel 7 inwalls, second O-ring seals 9 is arranged.Have seal groove on the oil sealing 13, between seal groove and cylinder barrel 7 inwalls, first O-ring seals 5 is arranged.
Working principle: because compression air cavity 19 is filled with the very high pressurized gas of air pressure, the vibration damper active chamber is comprised remain sufficient fluid in oily piston rod chamber 14 and the oily piston rodless cavity 18, play damping function by throttling groove 16 between oil piston rod chamber 14 and the oily piston rodless cavity 18, thereby make the working position limited by setting angle.
