Background technique
Air spring is a kind of industry accessories that can play support, buffering, braking, the highly function such as adjustment and angle adjustment; In airtight pressure cylinder, be filled with inert gas or gas mixture, make the pressure in cavity higher than atmospheric several times or tens times, utilize the cross-section area of piston rod be less than piston cross-section area thus produce pressure difference to realize the motion of piston rod.But current air spring is on the market that the stroke of stretching, extension is all less than the length of cylinder barrel by the structural limitations of himself, is not suitable for installing and using in the conditional occasion of part installing space, is thus necessary to carry out studying and improving for existing air spring structure.
Model utility content
One of the purpose of this utility model is for above-mentioned deficiency, a kind of air spring of multilevel hierarchy is provided, be less than the length of cylinder barrel with the extension stroke expecting to solve air spring in prior art, be not suitable for technical problems such as installing and using in the conditional occasion of part installing space.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
The air spring of a kind of multilevel hierarchy provided by the utility model, comprise the first cylinder barrel, the first described cylinder barrel inside is provided with first piston, described first piston is installed on the piston rod, described piston rod extends to the outside of the first cylinder barrel end through the first pilot seal mechanism, described first pilot seal mechanism is placed on the end of the first cylinder barrel, the front end of described first cylinder barrel is provided with the second piston, the outside of described first cylinder barrel is also set with the second cylinder barrel, the end of described second cylinder barrel is provided with the second pilot seal mechanism, described first cylinder barrel is through the second pilot seal mechanism, the front end of described second cylinder barrel is provided with tail and blocks up or the 3rd piston.
As preferably, further technological scheme is: described first pilot seal mechanism is placed between piston rod and the first cylinder barrel.
Further technological scheme is: described second pilot seal mechanism is placed between the first cylinder barrel and the second cylinder barrel.
Further technological scheme is: described first cylinder barrel is equal with the length of the second cylinder barrel, and described piston rod is equal with the length of the first cylinder barrel.
Further technological scheme is: be provided with O RunddichtringO between the inwall of described first piston and the first cylinder barrel, is also provided with O RunddichtringO between described second piston and the inwall of the second cylinder barrel.
Compared with prior art, one of the beneficial effects of the utility model are: by adopting multistage cylinder barrel, cylinder barrel is made namely to be the cylinder barrel of spring at the corresponding levels, it is again the piston rod of next stage spring, make air spring can obtain the extension stroke being greater than its cylinder barrel length by the mode mutually superposed, namely in a contracted state, take less space, comparatively be suitable for using in the conditional occasion of installing space, the air spring structure of a kind of multilevel hierarchy provided by the utility model is simple simultaneously, be suitable for industrialized production, be easy to promote.
Accompanying drawing explanation
Fig. 1 is the structural representation for illustration of the utility model embodiment;
Fig. 2 is the structural representation for illustration of the utility model another state of embodiment;
In figure, 1 be the first cylinder barrel, 2 be first piston, 3 be that the second pilot seal mechanism, 8 is for tail is stifled or the 3rd piston, 9 is O RunddichtringO for piston rod, 4 be the first pilot seal mechanism, 5 be the second piston, 6 is the second cylinder barrel, 7.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
Shown in figure 1, an embodiment of the present utility model is a kind of air spring of multilevel hierarchy, comprise the first cylinder barrel 1, and the first cylinder barrel 1 inside is provided with first piston 2, first piston 2 is arranged on piston rod 3, piston rod 3 extends to the outside of the first cylinder barrel 1 end through the first pilot seal mechanism 4, first pilot seal mechanism 4 is then placed on the end of the first cylinder barrel 1, what is more important, the front end of aforementioned first cylinder barrel 1 is also provided with the second piston 5, and the outside of the first cylinder barrel 1 is also set with the second cylinder barrel 6, and the end of the second cylinder barrel 6 is provided with the second pilot seal mechanism 7, first cylinder barrel 1 is through the second pilot seal mechanism 7, the front end of this second cylinder barrel 6 is provided with tail and blocks up or the 3rd piston 8, under the mentality of designing of aforementioned multistage air spring, by setting up piston, the mode of cylinder barrel and pilot seal mechanism arranges the air spring unit of next stage, further to increase the stroke that air spring stretches, and no matter increase what spring unit, under the contraction state shown in Fig. 2, the length of air spring is the length of most external cylinder barrel.
Go out as shown in Figure 1, above-mentioned first pilot seal mechanism 4 is placed between piston rod 3 and the first cylinder barrel 1, and the second pilot seal mechanism 7 is placed between the first cylinder barrel 1 and the second cylinder barrel 6
In the present embodiment, by adopting multistage cylinder barrel, cylinder barrel is made to be the cylinder barrel of spring unit at the corresponding levels, it is again the piston rod of next stage spring unit, make air spring can obtain the extension stroke being greater than its cylinder barrel length by the mode mutually superposed, namely in a contracted state, take less space, be suitable for very much using in the conditional occasion of installing space, in narrow space, obtain larger spread length.
According to another embodiment of the present utility model, for making above-mentioned multistage air spring unit, all there is identical stretching speed, need the structure with reference to conventional air spring, make to keep gap between the inwall of the outer wall of the first cylinder barrel 1 and the second cylinder barrel 6, and above-mentioned first cylinder barrel 1 also can be set to equal with the length of the second cylinder barrel 6, piston rod 3 also can be set to equal with the length of the first cylinder barrel 1, further to reduce space shared under air spring contraction state; On the other hand, leak with the gap between piston and inner wall of cylinder for preventing the gas in cylinder barrel, affect the elasticity of air spring, between first piston 2 and the inwall of the first cylinder barrel 1, and O RunddichtringO 9 can be set up between the second piston 5 and the inwall of the second cylinder barrel 6; As also needed to set up next stage air spring unit in actual use, also O RunddichtringO can be also set between piston and cylinder barrel.
Than that described above, also it should be noted that spoken of in this manual " embodiment ", " another embodiment ", " embodiment " etc., refer to the specific features, structure or the feature that describe in conjunction with this embodiment and be included at least one embodiment of the application's generality description.Multiple place occurs that statement of the same race is not necessarily refer to same embodiment in the description.Furthermore, when describing specific features, structure or a feature in conjunction with any embodiment, what advocate is also drop in scope of the present utility model to realize this feature, structure or feature in conjunction with other embodiments.
