Abstract
The utility model relates to a novel muffler assembly with deadener disposed around the muffler pipe, comprising a muffler and an intake muffler pipe and an exhaust muffler pipe both with muffler holes arranged on connected to the two ends of the muffler, the muffler is made up of a molding barrel and two end closures welded on the two ends of the cylinder, characterized in that surfaces of the intake muffler pipe and the exhaust muffler pipe in the barrel are provided with deadener. The out surface of the intake muffler pipe and the exhaust muffler pipe in the barrel are packed with deadener, after going through the muffler pipe in the muffler cylinder, he the high frequency noise waveform is absorbed and filtered by the deadener packed out the muffler pipe, and the high frequency noise waveform is weakened a lot, then the frequency reduced noise waveform is discharged from the exhaust muffler pipe, and the boom in passengers' ears brought about is reduced a lot.
Description
Technical field
The utility model relates to a kind of silencing apparatus, especially relates to a kind of model muffler assembly that is provided with muffler material around hush tube.
Background technique
At present, the muffler assembly that is used for automobile exhaust system mainly comprises silencing apparatus and main muffler, the central silencer two ends are connected with intake noise reduction pipe and exhausting silencer pipe, be equipped with sound attenuation hole on intake noise reduction pipe and the tailpipe, sound attenuation hole is traditionally arranged to be 200 holes, and silencing apparatus is made up of staving and two end caps that are connected the staving two ends, and staving is the rectangular shape that a metal foil is rolled into both ends open, end cap is a rectangular sheet structure, and the shape of end cap matches with the port of staving.This muffler assembly is installed in when working on the automobile, because this silencing apparatus is a reactive muffler, so after noise enters silencing apparatus from the intake noise reduction pipe, silencing apparatus to the absorption of noise seldom, when noise when tailpipe is gone out, it is still higher that its frequency shows as high-frequency noise, makes that automobile noise when starting is bigger, directly has influence on passenger comfort.
The model utility content
The utility model silencing apparatus, mainly be lower to noise absorption efficient in order to solve the existing in prior technology silencing apparatus, when noise waveform when tailpipe passes through, its frequency is still higher, the problem of automobile noise bigger grade in bottom, pilot set position when starting provides a kind of and has absorbed the novel preferably rear muffler assembly of noise result by the silencing apparatus that makes that is provided with muffler material around hush tube.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of model muffler assembly, comprise intake noise reduction pipe and exhausting silencer pipe that silencing apparatus is connected with its two ends, be equipped with sound attenuation hole on intake noise reduction pipe and the exhausting silencer pipe, silencing apparatus is made up of moulding cylindrical shell and two end caps that are welded on the staving two ends, it is characterized in that: the intake noise reduction pipe in the described staving and the outer surface of tailpipe are provided with sound-absorbing material.The intake noise reduction pipe in the cylindrical shell and the outer surface of exhausting silencer pipe are surrounded by sound-absorbing material, the high frequency noise waveform is by in the silencer cylinder during hush tube, after passing the sound-absorbing material absorbing and filtering of sound attenuation hole outside wrapping in hush tube, its high-frequency noise waveform weakens greatly, after noise waveform after the frequency reducing is discharged by the exhausting silencer pipe, reduced the boom that high-frequency noise comes for passenger's ear sideband greatly.
As preferably, described cylindrical shell is the cylinder bodily form, and described end cap is frustoconic shape or half bowl-type.
As preferably, described sound-absorbing material is a Sound-proof material.Sound-absorbing material adopts the assimilation effect of noise Sound-proof material preferably, and noise is through behind the Sound-proof material, and major part all is absorbed.
As preferably, described sound attenuation hole is 500～1000 orders.The hole order of sound attenuation hole is 500～1000 orders, and acoustically effective is better.
As preferably, described Sound-proof material is a tubular structure, and Sound-proof material is set in the intake noise reduction pipe in the staving and the outer surface of exhausting silencer pipe.It is more abundant to absorb noise, helps the absorption to noise waveform.
Therefore, the utlity model has following characteristics: 1. simple in structure, reasonable in design; 2. the outer surface of intake noise reduction pipe in the staving of silencing apparatus and exhausting silencer pipe is provided with sound-absorbing material, and noise is behind the process absorbing and filtering of sound-absorbing material, and its frequency reduces greatly, and it is effective to eliminate the noise; 3. Sound-proof material is set in the intake noise reduction pipe in the staving and the outer surface of tailpipe with sleeve-shaped, and it is more abundant to absorb noise.
Description of drawings
