Abstract
The invention relates to an automobile exhaust silencer which comprises a shell. An air inlet pipe, connection pipes and an air outlet pipe which are communicated with one another are sequentially arranged in the shell. The automobile exhaust silencer is characterized in that multiple air outlet through holes are formed in the walls of the air inlet pipe, the connection pipes and the air outlet pipe respectively, partition plates are arranged in the air inlet pipe and the connection pipes, communication through holes are formed in the partition plates, and the containing spaces of the connection pipes are larger than the containing space of the air inlet pipe and the containing space of the air outlet pipe; a damping material is arranged on the inner wall of the shell. The automobile exhaust silencer is simple in structure and good in silencing effect.
Description
Technical field
The present invention relates to noise reduction technical field, specifically a kind of automobile exhaust muffler.
Background technique
at present, automobile has entered in the life of ordinary family, noise miscellaneous can be produced during automobile running, automobile exhaust noise is exactly the one in car noise, along with the raising to car noise control overflow, automobile exhaust pipe also all loads onto baffler, the design of baffler is progressively paid attention to, but the structure of current automobile exhaust muffler is also comparatively complicated, erasure effect need to improve.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of structure simple, the good automobile exhaust muffler of erasure effect.
The technical solution adopted in the present invention is: provide a kind of automobile exhaust muffler, comprise housing, the suction tude of connection, connecting tube and steam outlet pipe is provided with successively in described housing, it is characterized in that: the tube wall of described suction tude, connecting tube and steam outlet pipe is equipped with multiple go out vent hole, dividing plate is provided with in suction tude and connecting tube, described dividing plate offers connection through hole, the holding space of connecting tube is all greater than the holding space of suction tude and steam outlet pipe; The inwall of described housing is provided with sound absorbing material.
After adopting above structure, automobile exhaust muffler of the present invention is all greater than suction tude and steam outlet pipe due to the holding space of connecting tube, the gas velocity entered is slack-off, noise obtains certain alleviation, make a part of gas successively by suction tude, connecting tube and steam outlet pipe by shunting, another part gas passes through in the space between vent hole ejection housing and each pipe, is absorbed by sound absorbing material, structure of the present invention is simple, and erasure effect obtains good improvement.
As preferably, described sound absorbing material is wave-like type, can strengthen the effect of noise reduction further.
As preferably, the excircle of described housing is provided with radiating fin, plays good effect to the radiating effect of housing.
Accompanying drawing explanation
Fig. 1 is the structural representation of automobile exhaust muffler of the present invention.
In figure, 1, suction tude, 2, housing, 3, connecting tube, 4, steam outlet pipe, 5, sound absorbing material, 6, radiating fin, 7, go out vent hole, 8, dividing plate.
Embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
as shown in Figure 1, automobile exhaust muffler of the present invention, comprise housing 2, housing 2 cross section is circular, the suction tude 1 of connection is provided with successively in housing 2, connecting tube 3 and steam outlet pipe 4, suction tude 1 and steam outlet pipe 4 extend outside housing 2, namely suction tude 1 is communicated with connecting tube 3, connecting tube 3 is communicated with steam outlet pipe 4, suction tude 1, the tube wall of connecting tube 3 and steam outlet pipe 4 is equipped with multiple go out vent hole 7, go out vent hole 7 and be all located at housing 2 inner region, dividing plate 8 is provided with in suction tude 1 and connecting tube 3, dividing plate 8 offers connection through hole, the holding space of connecting tube 3 is all greater than the holding space of suction tude 1 and steam outlet pipe 4, the volume namely holding gas in connecting tube 3 is all greater than the accommodation gas volume of suction tude 1 and steam outlet pipe 4, the inwall of housing 2 is provided with sound absorbing material 5.
In the specific implementation, sound absorbing material 5 is wave-like type in the present invention, and namely sound absorbing material 5 is wave-like type towards the surface of suction tude 1, connection 3 pipe and steam outlet pipe 4, and sound absorbing material 5 adopts acoustical cotton; The excircle of housing 2 is provided with radiating fin 6, and for improving the radiating effect of housing 2, radiating fin 6 is located on the part area of housing 2 excircle, facilitates taking of housing 2.
Claims (3)
