Description
Technical field
The invention belongs to auto-parts technical fields, and in particular to a kind of mobile muffler.
Background technology
Mobile muffler is the important composition component of automobile, and the noise for advantageously reducing the generation of vehicle traveling process is dirty
Dye.Mobile muffler is broadly divided into resistive muffler, resistant noise-reducing device, impedance complex formula muffler according to operation principle.It is resistive
Muffler is exactly the sound absorption using sound-absorbing material, makes constantly by absorption gradually to be decayed along the noise that passage is propagated.It is resistive
Muffler is suitable for eliminating the noise of middle and high frequency.Resistant noise-reducing device is that the pipeline section of the connection abrupt change of cross-section or side connect on pipeline
Resonant cavity, using sound wave abrupt-change cross section occur reflection, interference phenomena such as, so as to achieve the purpose that noise elimination, be mainly used for narrowband
The control of noise and middle low noise.The impedance complex formula muffler used that resistive and two kinds of structure composites of resistance are got up is then knot
The two advantage has been closed, has realized good noise elimination effect in the range of basic, normal, high frequency.
At present, silencer casing is typically to be made by individual layer steel plate, can not effectively obstruct noise.Moreover, vapour
Vehicle muffler in use, inside some the sour curdling water generated due to engines tail gas liquefaction that can retain, it is long
If time is not excluded for, corrosion can be generated to muffler internal part (such as sound-absorbing material), directly affect muffler uses the longevity
Life.
The content of the invention
The present invention provides a kind of mobile mufflers, have many advantages, such as good corrosion resistance, good muffling effect and long lifespan.
To achieve the above object, the present invention provides following technical scheme：
A kind of mobile muffler, including shell, air inlet pipe, communicating pipe, air outlet pipe, first partition, second partition, the 3rd partition plate,
Shell is divided into four chambers by the first partition, second partition and the 3rd partition plate, and the outer casing bottom is oblique and distinguishes
It is connected with first partition, second partition and the 3rd partition plate, outer casing bottom intersects with first partition, second partition and the 3rd partition plate
Place is provided with osculum, and the air inlet pipe runs through first partition and second partition, and air inlet pipe is divided into two sections, and air inlet pipe leading portion is in cone
Shape, air inlet pipe surface are provided with gas port, run through first partition and second partition the communicating pipe, and connection pipe surface, which is provided with, to be led
Stomata, the air outlet pipe run through the 3rd partition plate, are surrounded outside air inlet pipe, communicating pipe and air outlet pipe and set sound absorbing layer, the sound-absorbing
Puigging is set between layer and shell.
Further, the outer casing bottom is tilted to the direction of air outlet pipe, and the gradient of outer casing bottom is 1 °~5 °.
Further, the material of the shell is titanium material.
Further, the material of the puigging is ABS resin.
Further, circular hole is offered on the first partition, second partition and the 3rd partition plate.
A kind of mobile muffler, its advantage are：
1. material used in shell of the present invention is titanium alloy material, good corrosion resistance, long lifespan, light weight meets automotive light weight technology
It is required that；
2. outer casing bottom of the present invention tilts, the sour curdling water that can generate engines tail gas liquefaction converges in itself and partition plate phase
It at friendship, and is discharged by osculum, so as to extend the muffler service life；
3. the pyramidal structure of air inlet pipe leading portion of the present invention can effectively play noise elimination effect by noise into line misregistration and diffusion.
