Abstract
The utility model discloses an automobile main silencer capable of reducing low frequency range noise, which comprises a casing, an air inlet pipe, an air outlet pipe, an air return pipe, a dimensional pipe and a partition plate. The automobile main silencer is characterized in that the casing is divided into three chambers, the air inlet pipe bypasses a first chamber from the outer side of the casing to extend into a second chamber, and the air return pipe penetrates from the first chamber to the third chamber. The air outlet pipe bypasses the second chamber and the third chamber from the first chamber to extend out of the casing, through hole sections are distributed on the air return pipe and the air outlet pipe, and the dimensional pipe extends into the second chamber from the third chamber. An inlet of the air outlet pipe in the first chamber is in a horn shape. The length of the through hole section of the air outlet pipe distributed in the third chamber is 100mm, the length of the through hole section of the air inlet pipe distributed in the second chamber is 75mm, and the length of the through hole section of the air return pipe distributed in the second chamber is 110mm. The automobile main silencer can effectively eliminate the low frequency range noise from 50 hertz (Hz) to 125 Hz.
Description
Technical field
The utility model relates to the auto parts field, is specifically related to a kind of automobile main muffler that can reduce the low-frequency range noise.
Background technique
During the motor car engine combustion gas, the pressure of waste gas changes rapidly at exhaust pipe mouth, produces vibration, and vibration produces noise.In the existing technology, in the outlet pipe of motor car engine, install silencing apparatus, silencing apparatus is used to consume flowed energy, reduces the pressure surge amplitude of air-flow, can play the effect that reduces noise.But in the silencing apparatus of existing motor car engine, it is big that air communication is crossed resistance, and the engine power loss that causes is big, oil consumption increases, and the power performance of automobile is descended, and the silencing apparatus of Hyundai Motor seldom can reduce the noise of low-frequency range.The utility model provides a kind of automobile main muffler that can reduce the low-frequency range noise to above technical barrier.
Summary of the invention
The utility model is to provide a kind of automobile main muffler that can reduce the low-frequency range noise, the low-frequency noise of eliminating 50-125HZ is had very big effect, and the utility model can improve the working life of silencing apparatus.
The technological scheme that the utility model adopts is: a kind of automobile main muffler that can reduce the low-frequency range noise; Comprise: housing, suction tude, steam outlet pipe, muffler, dimension pipe, dividing plate; It is characterized in that: dividing plate is divided into three chambers with housing, and suction tude reaches second chamber through first chamber outside housing, and muffler extends through the 3rd chamber from first chamber; Steam outlet pipe from first chamber through second chamber and the 3rd chamber; Reach outside the housing, be distributed with the through hole section on muffler and the steam outlet pipe, dimension Guan Congdi three chambers reach in second chamber.
Said steam outlet pipe is horn-like at the steam outlet pipe inlet of first chamber, and steam outlet pipe is distributed with the through hole section that length is 100mm at the 3rd chamber.
Said muffler is distributed with the through hole section that length is 110mm at second chamber.
Said suction tude is distributed with the through hole section that length is 75mm in second chamber.
The beneficial effect of the utility model is: the low-frequency range noise to eliminating 50-125HZ plays very big effect, increases the working life of silencing apparatus.
Description of drawings
Accompanying drawing is the structural representation of the utility model.Wherein, 1 is housing, and 2 is suction tude, and 3 is dividing plate, and 4 are the dimension pipe, and 5 is steam outlet pipe, and 6 is the through hole section, and 7 is the through hole section, and 8 is the through hole section, and 9 are the steam outlet pipe inlet, and 10 is muffler.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified: with reference to accompanying drawing; A kind of automobile main muffler that can reduce the low-frequency range noise comprises: housing 1, suction tude 2, steam outlet pipe 5, muffler 10, dimension pipe 4, dividing plate 3, and it is characterized in that: two dividing plates 3 are divided into three chambers with housing 1; Suction tude 2 reaches second chamber through first chamber outside housing 1; Muffler 10 extends through the 3rd chamber from first chamber, and steam outlet pipe 5, reaches outside the housing 1 through second chamber and the 3rd chamber from first chamber; Be distributed with through hole section 8 and 6 on muffler 10 and the steam outlet pipe 5, dimension is managed 4 and is reached second chamber from the 3rd chamber.
Steam outlet pipe 5 is horn-like at the steam outlet pipe inlet 9 of first chamber, and steam outlet pipe 5 is distributed with the through hole section 8 that length is 100mm at the 3rd chamber.
Muffler 10 is distributed with the through hole section 6 that length is 110mm at second chamber.
After the gas of motor vehicle emission gets into the automobile main muffler; Gas is come in from suction tude 2 earlier; After being inflated minimizing acoustic pressure power during through through hole section 7, successively get into behind muffler 10 and steam outlet pipe 5, cut down noisiness once more; Through the reduction of such one-level one-level, effectively eliminate the low-frequency range noise of 50-125HZ.
Through above mode of execution, the utility model is eliminated the low-frequency range noise of 50-125HZ effectively, can increase the working life of silencing apparatus.
