It must trust.Contain 2 layers or 4 layers of casing ply inside air travel adjustment, bear bigger internal pressure to make it have, therefore hold
Loading capability greatly enhances.In general, under the conditions of identical function, the initial cost of air travel adjustment be traditional, pneumatic or
The half of hydraulic cylinder cost is lower.
Embodiment 7
The rubber air spring can be used as air damping isolator.With advantages below：
Good isolation cushioning ability：Air damping isolator can provide what other any damping isolators can not compare
The isolation damping effect of best degree.Lower intrinsic frequency can be provided by setting up outside caisson.Highly control essence
Really：Air spring is to adjust operation height by air pressure inside.Air spring does not produce static friction between miscellaneous part.
In the case where bearing capacity changes, automatic regulating system pressure may insure stable operation height.Isolation efficiency is stable
And independent bearing shock absorbing characteristicses：Air damping isolator is unique, and its system frequency will not be with payload
And too big change is produced, therefore identical air damping can be used in each mount point in the equipment for have uneven load
Isolator.Effectively prevent from resonating：Air spring shock mitigation system can be designed to two kinds of intrinsic frequencies, it is possible to by cutting
Intrinsic frequency is changed to prevent from resonating.Good horizontal stability：Air spring has good horizontal stability.It is effective to reduce
Noise：Air damping isolator can reduce structure-borne noise, because it does not have caused spring shake in normal spiral spring
It is dynamic, therefore its own does not produce noise.
Operation principle of the present utility model is：The rubber air spring can be used as air travel adjustment.With following excellent
Point：For air travel adjustment compared with common air cylinder device, its profile is short and small, and minimum air travel adjustment is compressible to
45mm height, and the height that three maximum bent capsule air travel adjustments are compressible to is only 122mm.Air travel adjustment
Possess unique crooking ability, it can keep stroke without forked type joint by a camber line.Crooking ability is high.It is empty
Gas travel adjustment has internal manipulation bar, piston or sliding seal unlike common cylinder.So in the absence of general
The problem of seal of logical cylinder formula suspension arrangement easily damages for dust.Air travel adjustment can easily be installed in narrow
In small space.Which save set-up time and expense.Air travel adjustment with flexibility characteristics can also compensate for due to
Height of level is irregular caused by work progress.Because air travel adjustment does not have sliding seal, therefore unlike general
Ventilation cylinder easily rubs impaired like that.And air spring is further applied on truck and bus suspension arrangement,
Under this unfavorable environmental condition, it can still adhere to hundreds thousand of kilometers, and its durability and service life are trustworthy.
Contain 2 layers or 4 layers of casing ply inside air travel adjustment, increased with making it have the internal pressure born, therefore large carrying capacity
Big enhancing.In general, under the conditions of identical function, the initial cost of air travel adjustment be traditional, pneumatic or hydraulic cylinder into
This half or lower.The rubber air spring can be used as air damping isolator.With advantages below：Good isolation damping
Ability：Air damping isolator can provide the isolation damping effect of other best degree that any damping isolator can not compare
Fruit.Lower intrinsic frequency can be provided by setting up outside caisson.Highly control is accurate：Air spring is to pass through inside
Air pressure runs height to adjust.Air spring does not produce static friction between miscellaneous part.In the feelings that bearing capacity changes
Under condition, automatic regulating system pressure may insure stable operation height.Isolation efficiency stabilization and independent bearing shock absorbing characteristicses：It is empty
Gas damping isolator is unique, and its system frequency will not produce too big change with payload, therefore
Identical air damping isolator can be used in each mount point in the equipment for have uneven load.It is effective to prevent altogether
Shake：Air spring shock mitigation system can be designed to two kinds of intrinsic frequencies, it is possible to be prevented altogether by switching intrinsic frequency
Shake.Good horizontal stability：Air spring has good horizontal stability.It is effective to reduce noise：Air damping is isolated
Device can reduce structure-borne noise, and because it does not have caused spring vibrations in normal spiral spring, therefore its own is not produced
Raw noise.
, it is necessary to illustrate in the description of this rubber air spring, unless otherwise clearly defined and limited, term
" setting ", " connected " and " connection " should be interpreted broadly, for example, it may be fixedly connected or be detachably connected, or one
Connect body；Can be joined directly together, can also be indirectly connected by intermediary, can be the connection of two element internals.
For the ordinary skill in the art, it can understand that specific in the utility model of above-mentioned term containing with concrete condition
Justice.
The better embodiment of this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, can also be on the premise of this patent objective not be departed from one skilled in the relevant art's possessed knowledge
Make a variety of changes.
