Abstract
The utility model discloses a part for an automobile, in particular to an automobile muffler, which comprises a barrel body, a muffling baffle plate, an air inlet pipe, an air return pipe and an exhaust pipe, wherein the two ends of the barrel body are sealed. The automobile muffler is characterized in that the muffling baffle plate and an end cover of the barrel body are arranged in parallel, the air inlet pipe passes through the end cover of the barrel body and passes through the muffling baffle plate, the air return pipe passes through the muffling baffle plate, and the exhaust pipe passes through the muffling baffle plate. The automobile muffler has the beneficial effects that the automobile silencer uses stainless steel materials, is welded by an argon arc, the barrel body seams are welded through sewing, the corrosion resistance and the shock resistance are high, the service life is above 10 years, the muffling baffle plate is changed into a three-layer muffling baffle plate mode, thereby leading air in an air inlet diffusion chamber to directly impact the muffling baffle plate, and having extremely excellent muffling effect.
Description
(1) technical field
The utility model relates to a kind of vehicle component, particularly a kind of automotive muffler.
(2) background technique
Original silencing apparatus material comprises that sheet material, tubing and appurtenances are general steel plate, and the stack shell seam is crimping, and noise-reducing structure is two-layer silencing board.The shortcoming that this structure exists is: general steel plate material easy-to-rust, and working life, working life was shorter about 2 years; Stack shell seam crimping form easily produces the explosion phenomenon when engine displacement is big; Former two-layer silencing board form, the gas of air inlet explosion chamber directly impacts the inclusion end cap, influences erasure effect.
(3) summary of the invention
The utility model is in order to remedy the deficiencies in the prior art, and a kind of long service life, automotive muffler that soundproof effect is good are provided.
The utility model is achieved by the following technical solution:
A kind of automotive muffler, comprise sealed at both ends staving, silencing board, suction tude, muffler and outlet pipe, it is characterized in that: the end cap of described silencing board and staving be arranged in parallel, described suction tude is passed the end cap of staving and is passed silencing board, muffler, pass silencing board, outlet pipe passes silencing board.
The more excellent technological scheme of the utility model is: described suction tude is passed two silencing boards, the part of suction tude between two silencing boards is provided with some air outlet holes, described muffler passes three silencing boards, described outlet pipe passes another end cap of staving, and pass three silencing boards, be provided with air outlet hole between two silencing boards endways.
Described silencing board has three, and wherein two near the air inlet pipe ends, and one near the exhaust pipe end.Silencing board near the exhaust pipe end is provided with some return-air holes.
The beneficial effects of the utility model are: the utility model adopts stainless steel material, the argon arc welding, the stack shell seam is the seam weldering, not corrosion, shock strength height, reach working life more than 10 years, silencing board changes the direct impact sound reduction dividing plate of gas that three layers of silencing board form make the air inlet explosion chamber into, and erasure effect is very good.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Among the figure, 1 staving, 2 suction tude, 3 end caps, 4 silencing boards, 5 return-air holes, 6 mufflers, 7 outlet pipes, 8 air outlet holes.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises sealed at both ends staving 1, silencing board 4, suction tude 2, muffler 6 and outlet pipe 7, silencing board 4 be arranged in parallel with the end cap 3 of staving 1, described suction tude 2 is passed the end cap 3 of staving 1 and is passed silencing board 4, muffler 6 passes silencing board 4, and outlet pipe 7 passes silencing board 4.Suction tude 2 is passed two silencing boards 4, the part of suction tude 2 between two silencing boards 4 is provided with some air outlet holes 8, described muffler 6 passes three silencing boards 4, described outlet pipe 7 passes another end cap 3 of staving 1, and pass three silencing boards 4, be provided with air outlet hole 8 between two silencing boards 4 endways.Noise reduction has three every 4 plates, and wherein two near suction tude 2 ends, and one near outlet pipe 7 ends.Silencing board 4 near outlet pipe 7 ends is provided with some return-air holes 5.When using, gas moves along the direction that reference arrow is represented, silencing board 4 has three, has increased the run duration of gas in staving 1, strengthened erasure effect, the utility model adopts stainless steel material, the argon arc welding, and the stack shell seam is the seam weldering, not corrosion, shock strength height, reach working life more than 10 years, silencing board changes the direct impact sound reduction dividing plate of gas that three layers of silencing board 4 form make the air inlet explosion chamber into, and erasure effect is very good.
Claims (4)
1. automotive muffler, comprise sealed at both ends staving, silencing board, suction tude, muffler and outlet pipe, it is characterized in that: the end cap of described silencing board and staving be arranged in parallel, described suction tude is passed the end cap of staving and is passed silencing board, muffler, pass silencing board, outlet pipe passes silencing board.
2. automotive muffler according to claim 1, it is characterized in that: described suction tude is passed two silencing boards, the part of suction tude between two silencing boards is provided with some air outlet holes, described muffler passes three silencing boards, described outlet pipe passes another end cap of staving, and pass three silencing boards, be provided with air outlet hole between two silencing boards endways.
