Description
Technical field
The present invention relates to a kind of silencing means field, a kind of automobile exhaust muffler is related generally to.
Background technology
Mobile muffler, it is mainly used in reducing noise caused by the generator operation of motor vehicle, its principle is automobile row
Tracheae is made up of two different pipelines of length, and the two pipelines first separate to cross again, due to the length difference of the two pipelines
Value is equal to the half of the wavelength for the sound wave that automobile is sent so that two row sound waves interfere in superposition cancels out each other and weaken
The sound intensity, the sound for making to be transmitted through reduces, so as to play the effect of noise reduction.
The muffler of automobile is that it passes through drop for reducing automobile engine to exhaust noise critical component
Low, decay pressure at expulsion pulsation eliminates noise.The muffler of one superior performance, it can effective attenuation exhaust make an uproar
Sound, the power output of engine can not also be influenceed to greatest extent again.A kind of muffler of existing minicar, if
There is the housing of the closing of air inlet pipe and escape pipe, and the space in housing is separated into dilating effect and is total to by two pieces of orifice plates
Three chambers of ring effect, wherein air inlet pipe and escape pipe both pass through three chambers in housing, in the expansion chamber of centre,
Air inlet pipe and escape pipe are equipped with tube wall passage, and the mobile muffler soundproof effect of this structure is still not good enough, particularly pair
In the attenuation and unobvious of high frequency noise.Existing muffler internal structure is unreasonable simultaneously, and erasure effect is inadequate
Good, especially for the attenuation and unobvious of high frequency noise, and the gas in muffler shell body can produce air pressure backflow, right
The output powered belt of gas extraction system adversely affects, so as to increase the consumption of power output.Therefore design a kind of rational in infrastructure
Muffler be particularly important.
The content of the invention
In view of the above-mentioned problems, it is an object of the invention to provide a kind of automobile exhaust muffler is planted, the muffler structure is more
Adduction is managed, and farthest carries out noise reduction processing, is reduced output energy consumption, is improved automobile silencing effect, and be effectively reduced pair
The noise pollution of environment.
Technical scheme is used by the present invention solves above-mentioned technical problem：
A kind of automobile exhaust muffler, it is characterised in that including muffler shell, in addition to air inlet pipe and escape pipe, institute
State air inlet pipe and inside is extended to outside muffler shell, the escape pipe extends to outside, the air inlet from the inside of housing
Pipe is separated with escape pipe by baffle plate, and the inside of the muffler shell is provided with noise reduction thing, the air inlet pipe and escape pipe it is interior
Wall is concavo-convex thing, concavo-convex thing waviness on the inwall of air inlet pipe and escape pipe, the air inlet pipe inside muffler shell
Provided with some breather pipes one, the breather pipe one is evenly distributed on the both sides of air inlet pipe, and the breather pipe one includes passage one
With vent cap one, the passage one includes air admission hole one and venthole one；If the escape pipe inside muffler shell is provided with
Dry breather pipe two, the breather pipe two are evenly distributed on the both sides of escape pipe, and the breather pipe two includes passage two and ventilation
Duct two, the passage two include air admission hole two and venthole two；The noise reduction thing is filled in air inlet pipe, escape pipe and noise reduction
Gap between device enclosure interior；The outside of the housing of the muffler is provided with heat-sink shell.
Further, the air inlet pipe and escape pipe are into truncated conical shape, the isosceles of the cross section of the air inlet pipe and escape pipe
It is trapezoidal.
Further, the noise reduction thing is acoustical cotton.
Further, the noise reduction thing is provided with several, and several noise reduction things are distributed in muffler shell into honeycomb shape
Inside.
The advantage of the invention is that：
The automobile exhaust muffler is simple and reasonable, and erasure effect is very good, economical and practical, to greatest extent reduction pair
Environmental noise pollution, at the same can decelerating airflow move, while the full space between air inlet pipe and housing of sound-absorbing thing filling, simultaneously
Sound-absorbing thing is into honeycomb, and cushion area increase, guarantee more fully absorbs the energy that gas is brought, so that erasure effect is more
It is good.
