A kind of denoising device, including the spring being connected between upper bracket and undersetting, the top first coil of spring and
Elastomeric element is equipped between the second coil of top and between the second coil of lower part and lower part first coil of spring.
Technical solutions of the utility model further improvement lies in that: the elastomeric element is fixed by the connecting rod.
Technical solutions of the utility model further improvement lies in that: the connecting rod be 1, be arranged in upper bracket and lower branch
Between seat, connecting rod one end is fixed on undersetting, and the other end is flexibly connected with upper bracket or connecting rod one end is fixed on upper branch
On seat, the other end is flexibly connected with undersetting.
Technical solutions of the utility model further improvement lies in that: the connecting rod be 2, be separately fixed at upper bracket and
On undersetting.
Technical solutions of the utility model further improvement lies in that: annular with holes centered on the elastomeric element, elasticity
The thickness of component is less than the vertical range between two coils of spring.
Technical solutions of the utility model further improvement lies in that: the material of the elastomeric element be nanometer foam.
Technical solutions of the utility model further improvement lies in that: the elastomeric element is internal inert gas filled rubber
Rubber mat.
By adopting the above-described technical solution, the technological progress that the utility model obtains is:
A kind of denoising device of the utility model, is not only simple in structure, and is easily installed and dismantles, long service life, moreover it is possible to
It effectively reduces helical spring both ends first coil and noise that the second coil is generated due to contacting with each other, it is outstanding to reduce entire vehicle
The noise of frame system.
The utility model is kept away by being respectively provided with elastomeric element between the first coil of spring upper and lower ends and the second coil
Automotive suspension is exempted from use, has been produced between the first coil at helical spring both ends and the second coil due to contacting with each other
Raw noise, reduces the noise of entire vehicle suspension system.
By the setting of connecting rod, can effective secure resilient member, avoid elastomeric element due to spring coil
Squeeze and caused by fall off；One end of connecting rod is fixed, and the other end is movably connected on upper bracket or undersetting or connecting rod is
It two, is separately fixed on undersetting, is for that elastomeric element is enable to move with the compression of spring with upholding, it is ensured that bullet
Property component is constantly between the first coil at helical spring both ends and the second coil.
Elastomeric element is internal inert gas filled rubber pad, and one side rubber tool has good wearability, is very high
Elasticity, breaking strength and elongation, can effectively resist the friction of the first coil and the second coil at compressed spring both ends to it,
Long service life；Filled with inert gas in rubber pad, when rubber pad is squeezed by spring coil, gas can flow in rubber pad
It is dynamic, so that entire rubber pad is adapted to the extruding of camber of spring and spring to rubber pad, preferably reduces vibration and noise.

Specific embodiment
The utility model is described in further details below with reference to embodiment:
Embodiment 1
Such as Fig. 1, shown in Fig. 3, a kind of denoising device, including the spring 3 being connected between upper bracket 1 and undersetting 2, spring
Between 3 top first coil 31 and the second coil of top 32 and the second coil of lower part 33 and lower part first coil of spring 3
Elastomeric element 4 is equipped between 34.By being respectively provided with elastic portion between the first coil and the second coil of 3 upper and lower ends of spring
Part 4 avoids automotive suspension in use, due to phase mutual connection between the first coil at helical spring both ends and the second coil
