Difference, and a kind of pressure change can only be accomplished, purposes is restricted.
Utility model content
The technical problems to be solved in the utility model is: in order to overcome the deficiencies in the prior art, this utility model
A kind of vibration and noise reducing dual rod type air spring is provided.
This utility model solves its technical problem and be the technical scheme is that a kind of vibration and noise reducing dual rod type gas
Spring, has cylinder barrel and piston component, and described piston component includes piston and piston rod, and piston is fixed on work
One end of stopper rod, and piston is positioned at cylinder barrel, vibration and noise reducing dual rod type air spring of the present utility model has two
Group piston component, two groups of piston components are symmetricly set on cylinder barrel two ends；It is respectively provided with inside the two ends of described cylinder barrel
Having vibration damping to seal structure, described vibration damping seals structure and includes two sealing rings, the inner ring of sealing ring and piston rod
Outer wall be tightly connected, the outer ring of sealing ring is connected with the inner wall sealing of cylinder barrel, and same vibration damping seals in structure
The curved surfaces that relative outer surface is evagination of two sealing rings, two piston phases of two groups of piston components
To surface be respectively provided with elastic bumps；The interior of described cylinder barrel has denoising structure, described denoising structure
Including hollow ring cavity and the acoustical panel of described cylinder barrel interior, described acoustical panel is arranged on described hollow
In annular housing.
In order to improve noise reduction, the inwall of described hollow ring cavity offers some bloops, described
Bloop is blind hole.
As preferably, described acoustical panel is cork.
In order to save cylinder barrel inner space, described elastic bumps is hemispherical projections, and the bullet on two pistons
Property protruding interlaced setting.
The beneficial effects of the utility model are, vibration and noise reducing dual rod type air spring of the present utility model, have two
Root piston and piston rod, and it is symmetricly set on the two ends of cylinder barrel, and avoid two pistons by elastic bumps
Between interference；It is provided with vibration damping inside the two ends of cylinder barrel and seals structure, not only make two piston rods be sealed,
Can play again buffering effect, and the curved surfaces that relative outer surface is evagination of two sealing rings, work as work
When stoppering two sealing rings of pressure, the curved surfaces of sealing ring deforms, the inside outward expansion of sealing ring stress,
Thus more improve the sealing property of sealing ring；It is provided with denoising structure, it is possible to effectively reduce inside cylinder barrel
The noise sent, improves comfort.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of vibration and noise reducing dual rod type air spring optimum embodiment of the present utility model.
In figure 1, cylinder barrel, 2, piston, 3, piston rod, 4, sealing ring, 4-1, curved surfaces, 5, bullet
Property protruding, 6, hollow ring cavity, 7, acoustical panel, 8, bloop.
Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are showing of simplification
Being intended to, basic structure of the present utility model is described the most in a schematic way, therefore it only shows and this utility model
Relevant composition.
As it is shown in figure 1, a kind of vibration and noise reducing dual rod type air spring of the present utility model, there is cylinder barrel 1 and two
Group piston component, described piston component includes piston 2 and piston rod 3, and piston 2 is fixed on the one of piston rod 3
Holding, and piston 2 is positioned at cylinder barrel 1, two groups of piston components are symmetricly set on cylinder barrel 1 two ends.
Being provided with vibration damping inside the two ends of described cylinder barrel 1 and seal structure, described vibration damping seals structure and includes two
Individual sealing ring 4, the inner ring of sealing ring 4 is tightly connected with the outer wall of piston rod 3, the outer ring of sealing ring 4 and cylinder
The inner wall sealing of cylinder 1 connects, and same vibration damping seals the relative outer surface of two sealing rings 4 in structure and is
The curved surfaces 4-1 of evagination, the surface that two pistons 2 of two groups of piston components are relative is respectively provided with elastic bumps 5；
Described elastic bumps 5 is hemispherical projections, and the interlaced setting of elastic bumps 5 on two pistons 2.
The interior of described cylinder barrel 1 has denoising structure, and described denoising structure includes described cylinder barrel 1 sidewall
Internal hollow ring cavity 6 and acoustical panel 7, described acoustical panel 7 is arranged in described hollow ring cavity 6.
Offering some bloops 8 on the inwall of described hollow ring cavity 6, described bloop 8 is blind hole.Described
