Abstract
The invention relates to an automobile part, particularly to an automobile muffler. The automobile muffler comprises a muffler inner shell, a muffler outer shell, an air inlet pipe, an air outlet pipe and a division plate; the muffler outer shell is arranged outside the muffler inner shell; sound insulating materials are arranged between the muffler outer shell and the muffler inner shell; the division plate is arranged in the muffler inner shell and provided with air holes; the inner chamber of the muffler inner shell is divided into the air inlet chamber, the middle chamber and the air outlet chamber through the division plate; the air inlet pipe penetrates the muffler outer shell, the muffler inner shell and the division plate and is communicated with the air outlet chamber and the outside of the muffler outer shell; the air outlet pipe penetrates the muffler outer shell, the muffler inner shell and the division plate and is communicated with the air inlet chamber and the outside of the muffler outer shell; the portions of the air inlet pipe and the air outlet pipe, which are located in the muffler inner shell, are provided with the air holes. According to the automobile muffler, the double layers of shells are adopted, the sound insulating materials are added between the double layers of shells, and accordingly the noise elimination and sound insulation effect of the automobile muffler can be effectively improved, the exhaust noise of an automobile exhaust pipe is reduced, and the automobile noise environment on the road is optimized.
Description
Technical field
The present invention relates to a kind of auto parts machinery, relate in particular to a kind of automotive muffler.
Background technique
Silencing apparatus is the important measures of eliminating air power noise and stoping Aerodynamic Noise of A.It is a weight constituent elements in automobile exhaust system, is beneficial to the noise pollution reducing in vehicle traveling process, utilizes sound wave stack principle of interference to be made.Baffler is mounted in the low noise device that falls on the air-flow path of aerodynamic force equipment or in inlet and exhaust system.Existing automotive muffler is general only connects respectively suction tude and steam outlet pipe on suppressor case, although structure is simple, cost is also relatively cheap, and its soundproof effect is not very desirable, can not meet the requirement of people to sound-deadening and noise-reducing.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of mobile muffler, can play better the effect of sound-deadening and noise-reducing, meets people's requirement.
