Description
Technical field
The utility model relates to chargers, and in particular to a kind of inflation of bitubular inflatable hydraulic automobile damper is set
It is standby.
Background technique
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 working principle is that connecting rod moves back and forth in working cylinder, drive damper oil liquid from
It flows to generate damping force repeatedly in working cylinder and oil storage cylinder 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, to effectively improve the compensation ability of recuperation valve, and improve idle running
Critical speed, guarantee damper can be worked normally in desin speed.
But current charger is largely to puncture oil sealing by air tube to be inflated, and is caused in this way to oil sealing
Easily there are the failures such as oil sealing breakage, oil leak in the damper work later period in irreversible destruction.Therefore it provides one kind avoids filling
Oil sealing is destroyed when gas, is that those skilled in the art are urgently to be resolved to extend the aerated equipment of damper service life
Problem.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of charger of bitubular inflatable hydraulic buffer,
When using the charger 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, technical solution adopted in the utility model is：A kind of bitubular inflatable is hydraulic to be subtracted
The charger of vibration device, including bracket, set fixing axle on the top of the bracket, and the inflation dress that can be rotated about is set in fixing axle
It sets；The workbench that height is adjustable is set in bracket lower part, damper rest area is set between workbench and air charging system, in bracket lower part
Inflating controller is also set, gas 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 charger of the utility model designed bitubular inflatable hydraulic buffer by adopting the above technical scheme, has
Following beneficial 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 maintenance, and equipment volume is small, raw
Is produced from place to occupy less；
3. easy to operate in production process, operator's operation error step is reduced to greatest extent, is conducive to safe and efficient
Production；
4. the replacement of air charging system tooling is convenient, is applicable to the production of variety classes damper.

Specific embodiment
The charger of the utility model bitubular inflatable hydraulic buffer is illustrated with reference to the accompanying drawing.
Referring to Fig. 1 to Fig. 5, the charger of the utility model bitubular inflatable hydraulic buffer, including bracket 6 and air tube
9, fixing axle 13 is set on the top of bracket 6, the air charging system 1 that can be rotated around fixing axle 13 is set in fixing axle 13.The utility model
Air charging system 1 be a gas chamber 12, the lower ending opening of gas chamber 12, the opening of gas chamber 12 is equipped with sealing ring 11.Under bracket 6
Portion sets workbench 3, and workbench 3 is connected through a screw thread with bracket 6, and workbench 3 can be adjusted and consolidate with the length of damper 2
It is fixed, damper rest area is set between workbench 3 and air charging system 1, damper rest area is used to be to place damping to damper inflation
Device.Inflating controller 4 is also set in the lower part of bracket 6, gas source 7 is connect by inflating controller 4 with 1 pipeline of air charging system, is inflated
The floor push 5 of control air inlet is also provided on controller 4.
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
In the oil sealing 10 of 9 insertion dampers 2, then air charging system 1 is rotated 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 gas 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.It is finished wait inflate
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 touching makes the inside of damper form pressure by the air seal for being filled with damper 2 inside damper.It grasps and subtracts
Vibration device 2 simultaneously rotates outward, and air charging system 1 is driven to rotate to certain angle, takes out damper 2.Air tube 9 is by 10 bullet of oil sealing at this time
Part out need to only take out air tube 9, and oscillating damper inflation is completed.
The utility model is on probation through manufacturing experimently, and the defect of oil sealing is destroyed when overcoming existing oscillating damper inflation, extends oil sealing
Service life, be the ideal charger of bitubular inflatable hydraulic automobile damper.
