Abstract
The utility model discloses a kind of automotive muffler, comprise housing, be arranged on the suction tude in housing, outlet pipe and arm, one end of described suction tude and arm forms the first anechoic chamber, the other end of described arm and outlet pipe form the second anechoic chamber, be provided with screw rod in described outlet pipe, the outer surface of described housing is provided with buffer layer, in described suction tude, outlet pipe and arm, be respectively arranged with muffle coating.The utility model utilizes combining of suction tude, outlet pipe and arm to reduce pressure and noise reduction, reduce silencing apparatus body internal pressure, improve the erasure effect of silencing apparatus, and the screw rod by arranging in outlet pipe, waste gas can be made to produce vortex and discharge more fast.
Description
Technical field
The utility model relates to technical field of automobile parts, particularly relates to a kind of automotive muffler.
Background technique
Automotive muffler, the noise produced when being mainly used in the generator operation reducing Motor Vehicle, to be automobile exhaust pipe be made up of the pipeline that two length is different its principle, 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, two row sound waves are interfered when superposing cancel out each other and weaken the sound intensity, the sound that biography is come reduces, thus play the effect of noise reduction, but the silencing apparatus internal structure of automobile is complicated at present, erasure effect is general, and silencing apparatus body internal pressure is easily too high, exhaust resistance is large, reduce the effect of noise elimination, and exhaust is easily obstructed, reduce silencing apparatus working efficiency.
Model utility content
For overcoming above-mentioned deficiency, the invention provides and a kind ofly can effectively reduce silencing apparatus body internal pressure and working efficiency is high, the automotive muffler of good muffling effect.
The technical solution adopted in the utility model is: a kind of automotive muffler, comprise housing, be arranged on the suction tude in housing, outlet pipe and arm, one end of described suction tude and arm forms the first anechoic chamber, the other end of described arm and outlet pipe form the second anechoic chamber, be provided with screw rod in described outlet pipe, the outer surface of described housing is provided with buffer layer, in described suction tude, outlet pipe and arm, be respectively arranged with muffle coating.
As the further setting of such scheme, described suction tude and arm are provided with pore, described pore is provided with silencing cotton.
As the further setting of such scheme, described screw rod is provided with screw piece, described screw piece is provided with pore.
As the further setting of such scheme, described buffer layer is inflated insert or steel net pad.
The utility model utilizes combining of suction tude, outlet pipe and arm to reduce pressure and noise reduction, reduce silencing apparatus body internal pressure, improve the erasure effect of silencing apparatus, and the screw rod by arranging in outlet pipe, waste gas can be made to produce vortex and discharge more fast.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: 1, housing; 2, suction tude; 3, outlet pipe; 4, arm; 5, the first anechoic chamber; 6, the second anechoic chamber; 7, screw rod; 8, buffer layer; 9, pore; 10, screw piece.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described further.
As shown in Figure 1, a kind of automotive muffler, comprise housing 1, be arranged on the suction tude 2 in housing 1, outlet pipe 3 and arm 4, described suction tude 2 forms the first anechoic chamber 5 with one end of arm 4, the other end of described arm 4 and outlet pipe 3 form the second anechoic chamber 6, screw rod 7 is provided with in described outlet pipe 3, the outer surface of described housing 1 is provided with buffer layer 8, described suction tude 2, muffle coating is respectively arranged with in outlet pipe 3 and arm 4, described suction tude 2 and arm 4 are provided with pore 9, described pore 9 is provided with silencing cotton, described screw rod 7 is provided with screw piece 10, described screw piece 10 is provided with pore 9, described buffer layer 8 is inflated insert or steel net pad.
Working principle of the present utility model is as follows: the waste gas of vehicular discharge is by entering after suction tude 2 imports, noise reduction of reducing pressure for the first time is done by the first anechoic chamber 5 that waste gas can enter housing 1, and import the second anechoic chamber 6 by arm 4 and do second time and to reduce pressure noise reduction, and exhaust gas section in suction tude 2 and arm 4 can directly be discharged in housing 1 to mix with the pore 9 on arm 4 reduce pressure by being arranged on suction tude 2, and subtract wave by the noise reduction of silencing cotton, subtract ripple sound-absorbing, passed through to produce vortex with the pore 9 be arranged on screw piece 10 by outlet pipe 3 screw piece 10 on the screw rod 7 and screw rod 7 of hollow shape again, and accelerate to discharge in air, in the whole process of waste gas by silencing apparatus, receive suction tude 2 simultaneously, the noise reduction of the muffle coating arranged respectively in outlet pipe 3 and arm 4 subtracts wave, the stronger erasure effect improving silencing apparatus.
