Abstract
The utility model discloses a trifurcate automobile main muffler, which includes a housing, an air inlet pipe, an air outlet pipe, an air return pipe, a semi-closed pipe, a dimension pipe and baffle plates, and is characterized in that the two baffle plates divide the housing into three cavities; the air inlet pipe, the air return pipe and the semi-closed pipe are connected together in a third cavity so as to form a trifurcate shape; the inlets of the air inlet pipe, the air return pipe and the semi-closed pipe are arranged in a first cavity; the air inlet pipe extends from outside the housing to the third cavity through the first cavity; the air return pipe penetrates the third cavity from the first cavity; the air outlet pipe extends out of the housing from the third cavity; and the dimension pipe is arranged in the third cavity and wraps the air outlet pipe. The trifurcate automobile main muffler can effectively reduce the back pressure of the automobile exhaust gas, has excellent effect in removing 50 to 250HZ low-frequency noise, and can prolong the service life of the muffler.
Description
Technical field
The utility model relates to the auto parts field, is specifically related to a kind of triadius type automobile main muffler.
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 to reduce exhaust sound.Silencing apparatus dissipates exhaust energy through through reducing the pulse of exhaust pressure and decay exhaust pressure gradually, also cuts the power of consumption motor 10% ~ 15% simultaneously.But in the silencing apparatus of existing motor car engine; It is big that the air communication of automobile is crossed resistance; The engine power loss that causes easily is big, oil consumption increases; The power performance of automobile is descended, and the silencing apparatus of Hyundai Motor seldom can reduce the noise of low-frequency range, the elimination of low-frequency range noise does not also have mature technique.
Summary of the invention
The utility model provides a kind of triadius type automobile main muffler to above technical barrier, can effectively reduce the back pressure of automotive air discharging, the low-frequency noise of eliminating 50-250HZ is had good effect, and can improve the working life of silencing apparatus.
The technological scheme that the utility model adopts is: a kind of triadius type automobile main muffler comprises: housing, suction tude, steam outlet pipe, muffler, semiclosed pipe, dimension pipe, dividing plate, and it is characterized in that: two dividing plates are divided into three chambers with housing; Suction tude, muffler and semiclosed Guan Zaidi three chambers link together; Become three forked types, the inlet of suction tude, muffler, semiclosed pipe is at first chamber, and suction tude reaches the 3rd chamber through first chamber outside housing; Muffler extends through the 3rd chamber from first chamber; Steam outlet pipe reaches outside the housing from the 3rd chamber, dimension Guan Zaidi three chambers, and the dimension pipe is wrapping steam outlet pipe.
Said semiclosed pipe is horn-like at the inlet of first chamber, in the semiclosed pipe of second chamber the inside dividing plate is arranged.
Said steam outlet pipe is distributed with the through hole section at the 3rd chamber.
Said muffler and suction tude are distributed with the through hole section in the corner of the 3rd chamber, and the through hole section is fan-shaped distribution.
The beneficial effect of the utility model is: can effectively reduce the back pressure of automotive air discharging, the low-frequency noise of eliminating 50-250HZ had good effect, and can improve the working life of silencing apparatus.
Description of drawings
The internal structure schematic representation of Fig. 1 the utility model.
Wherein 1 is housing, and 2 is suction tude, and 3 is muffler, and 4 is semiclosed pipe, and 5 is the through hole section, and 6 is dividing plate, and 7 are the dimension pipe, and 8 is steam outlet pipe, and 9 is dividing plate, and 10 is the through hole section, and 11 is the through hole section.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified: with reference to accompanying drawing; A kind of triadius type automobile main muffler comprises: housing 1, suction tude 2, steam outlet pipe 8, muffler 3, semiclosed pipe 4, dimension pipe 7, dividing plate 9, and it is characterized in that: two dividing plates 9 are divided into three chambers with housing 1; Suction tude 2, muffler 3 and semiclosed pipe 4 link together at the 3rd chamber; Become three forked types, the inlet of suction tude 2, muffler 3, semiclosed pipe 4 is at first chamber, and suction tude 2 reaches the 3rd chamber through first chamber outside housing; Muffler 3 extends through the 3rd chamber from first chamber; Steam outlet pipe 8 reaches outside the housing from the 3rd chamber, and dimension pipe 7 is at the 3rd chamber, and dimension pipe 7 is wrapping steam outlet pipe.
Muffler 3 is distributed with through hole section 5,10 with suction tude 2 in the corner of the 3rd chamber, through hole section 5,10 is fan-shaped distribution.
At first the gas of motor vehicle emission is after suction tude 2 gets into silencing apparatus; Through hole section 5,10 at the 3rd chamber expands, and acoustic pressure power can diminish, when getting into first chamber through muffler 3 then; In semiclosed pipe 4, eliminate the acoustic pressure power of a part again; All gas expands at steam outlet pipe 8 again, reduces its acoustic pressure power, and then gaseous emission is gone out.Greatly reduce the acoustic pressure power of automobile emission gas like this.
The utility model can effectively reduce the back pressure of automotive air discharging, the low-frequency noise of eliminating 50-250HZ is had good effect, and can improve the working life of silencing apparatus.
