Description
Technical field
The utility model belongs to damping air spring product technical field, more particularly to double with height adjusting function
Piston air spring.
Background technology
In the prior art, conventional air spring constructions are made up of upper cover plate, rubber pneumatic bag, lower piston, after three's assembling
Form a sealing space.For air spring during compressing with recovery, internal pressure-air provides bearing capacity.Upper cover plate
The upper port of air spring is fixed with flange pressure ring with rubber pneumatic bag, lower piston is compressed solid with rubber pneumatic bag with vertical compression ring
Determine the lower port of air spring.In the operating condition, rubber pneumatic bag can turn down in lower port, then abut in lower piston surface
On, but the upper port of rubber pneumatic bag is constrained by flange pressure ring, does not turn down.It is piston-shaped to air spring bearer properties
Influence it is very big, but single flange air spring only has a lower piston, therefore, in the design process, can not flexibly adjust
The height and bearer properties of air spring.
Therefore, it is extremely urgent to research and develop a kind of double-piston air spring with height adjusting function.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, specifically discloses a kind of double-piston air spring, the sky
Gas spring has different crimped states under different working depths, and can provide different bearing capacitys and isolation characteristicses, its
It is applied widely, strong adaptability.
In order to reach above-mentioned technical purpose, the utility model is realized by following technical scheme：
A kind of double-piston air spring described in the utility model, including rubber pneumatic bag, the upper port of the rubber pneumatic bag
Upper piston is installed at place, is provided with lower piston at lower port, the bottom periphery of the upper piston is arranged with upper press ring, the top of lower piston
Portion periphery is arranged with lower pressure ring, and the upper press ring is vertical compression ring.
As the further improvement of above-mentioned technology, the upper press ring is compressed by ring squeezer, the upper press ring and upper piston
Bottom periphery be interference fit.
As the further improvement of above-mentioned technology, the lower pressure ring is compressed by ring squeezer, the lower pressure ring and lower work
The top periphery of plug is interference fit.
In the utility model, the shape of the upper piston does suitability change.
Compared with prior art, the beneficial effects of the utility model are：
(1) the flange pressure ring of the prior art for being used to rubber pneumatic bag being pressed on upper cover plate is substituted for by the utility model
Vertical compression ring, and by upper cover plate be substituted for needed for shape upper piston, turned in order to which rubber pneumatic bag can also be produced at upper port
Folding, and then upper piston and the coiled pressure condition of energy are abutted in, height regulation can carried out to air spring, so as in different height
Obtain different bearing capacitys and isolation characteristicses.
(2) in the utility model, upper piston can be designed to required shape, to reach different performance requirements.
(3) in the utility model, upper press ring can be unified for the vertical compression ring of standard component, reduce cost.
Brief description of the drawings
The utility model is described in detail with specific embodiment below in conjunction with the accompanying drawings：
Fig. 1 is the installation assembling schematic diagram of double-piston air spring described in the utility model.
Fig. 2 is crimped state of the double-piston air spring described in the utility model under relatively low working depth.
Fig. 3 is crimped state of the double-piston air spring described in the utility model under compared with high workload height.
Embodiment
As shown in Figure 1 to Figure 3, a kind of double-piston air spring described in the utility model, including rubber pneumatic bag 1, it is described
Upper piston 2 is installed at the upper port of rubber pneumatic bag 1, lower piston 3, the bottom periphery set of the upper piston 2 are installed at lower port
Provided with upper press ring 4, the top periphery of lower piston 3 is arranged with lower pressure ring 5, and the upper press ring 4 is vertical compression ring.The upper press ring 4 is logical
Cross ring squeezer to compress, the bottom periphery of the upper press ring 4 and upper piston 2 is interference fit.As the further of above-mentioned technology
Improve, the lower pressure ring 5 is compressed by ring squeezer, and the top periphery of the lower pressure ring 5 and lower piston 3 is interference fit.At this
In utility model, the shape of the upper piston 2 does suitability change.
Detailed description below installation of the present utility model and the course of work：
(1) when installing, the one end of rubber pneumatic bag 1 is arranged on upper piston 2, the other end is arranged on lower piston 3, Ran Houfen
Upper press ring 4 and lower pressure ring 5 are not put, and compressing pressure ring with ring squeezer obtains air spring assembly, as shown in Figure 1.
(2) air spring assembly described in Fig. 1 is inflated, pushed, it is ensured that the both ends of rubber pneumatic bag 1 produce turnover, obtain
To the crimped state shown in Fig. 2.
(3) in motion process, when desired working depth is higher, the rolled state of rubber pneumatic bag 1 is as shown in Figure 2；
When desired working depth is relatively low, the rolled state of rubber pneumatic bag is as shown in Figure 3.
From the foregoing, it will be observed that when carrying out height regulation to air spring 1, different carrying energy can be obtained in different operating height
Power and isolation characteristicses, applicable scope is wide, strong adaptability.
The utility model is not limited to above-mentioned embodiment, and every various changes or modifications to the utility model do not take off
From spirit and scope of the present utility model, if these changes and modification belong to the claims and equivalents of the utility model
Within the scope of, then the utility model is also implied that comprising these changes and modification.
