Abstract
The invention provides an automobile exhaust muffler. The automobile exhaust muffler is characterized in that the muffler comprises a muffle shell and further comprises a gas inflow pipe and a gas outflow pipe; the gas inflow pipe extends into the muffler shell from the exterior of the muffler shell; the gas outflow pipe extends out of the muffler shell from the interior of the muffler shell; concave and convex articles are arranged on the inner wall of the gas inflow pipe and the inner wall of the gas outflow pipe and form wavy forms on the inner wall of the gas inflow pipe and the inner wall of the gas outflow pipe; a plurality of first ventilation pipes are arranged on the portion, inside the muffler shell, of the gas inflow pipe and evenly distributed on the two sides of the gas inflow pipe; a plurality of second ventilation pipes are arranged on the portion, inside the muffler shell, of the gas outflow pipe and evenly distributed on the two sides of the gas outflow pipe; and gaps between the gas inflow pipe and the inner portion of the muffler shell and between the gas outflow pipe and the inner portion of the muffler shell are filled with muffling matter. The automobile exhaust muffler is simple and reasonable in structure, and noise pollution to the environment is reduced to the maximum extent; and meanwhile, the sound absorbing matter forms a honeycomb structure, and therefore it is ensured that energy brought by gas is fully absorbed, and the muffling effect can be better.
Description
Technical field
The present invention relates to a kind of silencer field, relate generally to a kind of automobile exhaust muffler.
Background technique
Automobile
baffler, the noise produced when being mainly used in the generator operation reducing Motor Vehicle, its principle is
automobile exhaust pipethe pipeline different by two length is formed, and these two pipelines first separately cross again, due to these two pipelines length difference equal the half of the wavelength of the sound wave that automobile sends, make two row
sound waveinterfere when superposing and cancel out each other and weaken the sound intensity, the sound that biography is come reduces, thus plays the effect of noise reduction.
The muffler of automobile is used to the critical component reducing automobile engine to exhaust noise, and it carrys out stress release treatment by the pulsation of reduction, decay exhaust pressure.The muffler of a superior performance, it can effective attenuation exhaust sound, can also not affect again the output power of motor to greatest extent.The muffler of existing a kind of minicar, be provided with the housing closed of suction tude and steam outlet pipe, and by two pieces of orifice plates, the space in housing is separated into three chambers with dilating effect and sympathetic response effect, wherein suction tude and steam outlet pipe are all through the chamber of three in housing, in the expansion chamber of centre, suction tude and steam outlet pipe are equipped with tube wall vent, and the mobile muffler soundproof effect of this structure is good still not, particularly not obvious for the attenuation of high frequency noise.Existing muffler internal structure is unreasonable simultaneously, erasure effect is good not, particularly not obvious for the attenuation of high frequency noise, and the gas in muffler shell can produce air pressure backflow, adverse effect is brought to the outputting power of vent systems, thus will the consumption of output power be increased.Therefore design a kind of baffler rational in infrastructure and seem particularly important.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide kind of an a kind of automobile exhaust muffler, this muffler structure is more reasonable, farthest carry out noise reduction process, reduce and export energy consumption, improve automobile silencing effect, and effectively reduce the noise pollution to environment.
The present invention solves the problems of the technologies described above adopted technological scheme:
A kind of automobile exhaust muffler, it is characterized in that, comprise muffler shell, also comprise suction tude and steam outlet pipe, described suction tude extends to inside from muffler shell external body, described steam outlet pipe extends to outside from the inside of housing, described suction tude and steam outlet pipe are separated by baffle plate, the inside of described muffler shell is provided with unmuffle, the inwall of described suction tude and steam outlet pipe is concavo-convex thing, described concavo-convex thing is waviness on the inwall of suction tude and steam outlet pipe, the suction tude of muffler shell inside is provided with some breathing pipes one, described breathing pipe one is evenly distributed on the both sides of suction tude, described breathing pipe one comprises vent one and vent cap one, described vent one comprises inlet hole one and air outlet hole one, the steam outlet pipe of muffler shell inside is provided with some breathing pipes two, and described breathing pipe two is evenly distributed on the both sides of steam outlet pipe, and described breathing pipe two comprises vent two and vent cap two, and described vent two comprises inlet hole two and air outlet hole two, described unmuffle is filled in suction tude, gap between steam outlet pipe and muffler shell inside, the outside of the housing of described baffler is provided with heat-sink shell.
Further, described suction tude becomes truncated conical shape with steam outlet pipe, the isosceles trapezoid of the cross section of described suction tude and steam outlet pipe.
Further, described unmuffle is for being acoustical cotton.
Further, described unmuffle is provided with several, and several unmuffles become honeycomb shape to be distributed in the inside of muffler shell.
The invention has the advantages that:
This automobile exhaust muffler is simple and reasonable, erasure effect is very good, economical and practical, reduce to greatest extent environmental noise pollution, can move by decelerating airflow simultaneously, sound-absorbing thing fills full space between suction tude and housing simultaneously, sound-absorbing thing becomes cellular structure simultaneously, cushion area increases, and guarantee more fully absorbs the energy that gas brings, thus makes erasure effect better.
