Description
Technical field
The present invention relates to chargers, and in particular to a kind of charger of bitubular inflatable hydraulic automobile damper.
Background technology
Vehicle shock absorber is one of important component of automotive suspension, to the ride comfort, comfort, safety of running car
Property, steering operation and passability play an important role.A kind of important feature of the bitubular inflatable hydraulic buffer as damper
Form is widely used on various vehicles.Its operation principle is that connecting rod moves back and forth in working cylinder, drive damper fluid from
It flows in working cylinder and oil storage cylinder to generate damping force repeatedly between the hole of valve system, slows down the top generated in vehicle traveling process
It winnows with a dustpan, vibrate.Since bitubular hydraulic vibration absorber can generate idle running phenomenon under high speed operation state, idle running distortion is formed, is influenced
Damper efficiency, and directly affect damper and inhibit wheel switch power amplifie, it is therefore desirable to it is injected into damper a certain amount of lazy
Property gas, make to form certain pressure in oil storage cylinder, so as to effectively improve the compensation ability of recuperation valve, and improve idle running
Critical speed, ensure damper can be worked normally in desin speed.
But current charger is largely to puncture oil sealing by air tube to be inflated, and oil sealing is caused in this way
Easily there are the failures such as oil sealing breakage, oil leak in the damper work later stage in irreversible destruction.Therefore it provides one kind avoids filling
Oil sealing is destroyed during gas, is that those skilled in the art are urgently to be resolved hurrily so as to extend the aerated equipment of damper service life
Problem.
Invention content
The technical problems to be solved by the invention are to provide a kind of charger of bitubular inflatable hydraulic buffer, utilize
When the charger is to oscillating damper inflation, to oil sealing fanout free region, the oil sealing service life is not influenced.
In order to solve the above technical problems, the technical solution used in the present invention is：A kind of bitubular inflatable hydraulic buffer
Charger, including stent, fixing axle is set on the top of the stent, the air charging system that can be rotated about is set in fixing axle；
The workbench that height can be adjusted is set in stent lower part, damper rest area is set between workbench and air charging system, in stent lower part also
If inflating controller, air source is connect by inflating controller with air charging system, and control air inlet is also provided on inflating controller
Floor push.
The air charging system is a gas chamber, and the lower ending opening of gas chamber, gas chamber opening is equipped with sealing ring.
The present invention is had following using the charger of the bitubular inflatable hydraulic buffer designed by above-mentioned technical proposal
Advantageous effect：
1. during oscillating damper inflation, to oil sealing fanout free region, the oil sealing service life is not influenced；
2. device structure is simple, no complicated machinery hydraulic structure, easily controllable and maintaining, and equipment volume is small, produces field
Ground occupies few；
3. it is easy to operate in production process, operating personnel's operation error step is reduced to greatest extent, conducive to safe and efficient production；
4. air charging system tooling is replaced convenient, is applicable to the production of variety classes damper.

Specific embodiment
The charger of bitubular inflatable hydraulic buffer of the present invention is illustrated below in conjunction with the accompanying drawings.
Referring to Fig. 1 to Fig. 5, the charger of bitubular inflatable hydraulic buffer of the present invention, including stent 6 and air tube 9,
The top of stent 6 sets fixing axle 13, and the air charging system 1 that can be rotated around fixing axle 13 is set in fixing axle 13.The inflation dress of the present invention
1 is put as a gas chamber 12, the lower ending opening of gas chamber 12, the opening of gas chamber 12 is equipped with sealing ring 11.Work is set in the lower part of stent 6
Platform 3, workbench 3 are connected through a screw thread with stent 6, and workbench 3 can be adjusted and fix with the length of damper 2, work
Damper rest area is set between platform 3 and air charging system 1, damper rest area is used to be to place damper to damper inflation.It is propping up
The lower part of frame 6 also sets inflating controller 4, and air source 7 is connect by inflating controller 4 with 1 pipeline of air charging system, inflating controller 4
On be also provided with control air inlet floor push 5.
When being inflated to damper, the arc surface of air tube 9 and the connecting rod 8 of damper 2 are fitted closely first, then by air tube
9 are inserted into the oil sealing 10 of damper 2, then air charging system 1 rotate by a certain angle around fixing axle 13, then damper 2 is installed
On workbench 3, rotary inflator 1 makes its face damper 2, and the height of adjustment workbench 3 extend into 2 upper end of damper
It in the gas chamber 12 of air charging system 1, then is sealed by the rubber seal 11 of 12 entrance of gas chamber, is fixed on damper 2
Between air charging system 1 and workbench 3.Step on floor push 5, the inert gas in air source 7 enter in the gas chamber 12 of air charging system 1 into
Row inflation, inflating controller 4 control inflationtime, limit aeration quantity number, the time reach after stop inflation.Treat that inflation finishes
Afterwards, damper internal pressure is about 0.6~0.8MPa at this time, and the rear sealing lip of oil sealing 10 squeezes air tube under internal pressure effect
9, the tip injection section of air tube 9 is expressed into the cavity that oil sealing 10 and connecting rod 8 are formed, while rear sealing lip and connecting rod 8 are tight
Contiguity is touched, and by the air seal for being filled with damper 2 inside damper, the inside of damper is made to form pressure.It grasps and subtracts
It shakes and device 2 and rotates outward, air charging system 1 is driven to rotate to certain angle, take out damper 2.Air tube 9 is by 10 bullet of oil sealing at this time
Go out part, air tube 9 need to only be taken out, oscillating damper inflation is completed.
The present invention is on probation through manufacturing experimently, and when overcoming existing oscillating damper inflation the defects of destruction oil sealing, extends making for oil sealing
It is the ideal charger of bitubular inflatable hydraulic automobile damper with the service life.
