Description
Technical field
The present invention relates to automobile equipment technical field, specially a kind of blast pipe sleeve pipe with damping and silencing effect.
Background technology
But automobile exhaust pipe muffler in the market is all common, single noise-reducing structure, not only complex structure but also noise reduction effect is poor, because blast pipe easily shakes, can also so produce a large amount of noises, therefore, a kind of it is proposed that blast pipe sleeve pipe with damping and silencing effect.
The content of the invention
It is an object of the invention to provide a kind of blast pipe sleeve pipe with damping and silencing effect, to solve the problems, such as to be proposed in above-mentioned background technology.
To achieve the above object, the present invention provides following technical scheme：A kind of blast pipe sleeve pipe with damping and silencing effect, including tube wall, hush pipe, the tube wall is sandwich construction, first chamber is followed successively by from inside to outside, second chamber and the 3rd chamber, the inwall of the first chamber is provided with hole, one end of described hole connection rubber tube, and rubber tube is wave shape, the rubber tube is located inside first chamber, the other end of the rubber tube connects the inwall of second chamber and extends to the inside of second chamber, the hush pipe is the straight tube structure of endcapped, the front end of the hush pipe is connected with the other end of rubber tube, and noise reduction inside pipe wall is provided with bloop, the hush pipe is located inside second chamber, the end of the hush pipe connects the inner side of the 3rd chamber and extends to the 3rd chamber interior, sponge or foam are filled with 3rd chamber.
Preferably, described hole is evenly distributed on the inwall of first chamber.
Preferably, the inside of second chamber is filled with aluminum fiber or cellucotton.
Preferably, the tube wall outside is socketed with knop.
Compared with prior art, the beneficial effects of the invention are as follows：The sleeve pipe, the corrugated rubber tube being made up of rubber, cushioning effect can not only be played, but also the noise as produced by vibrations can be reduced, by being sponge, foam in the hush pipe and filled cavity of endcapped, the function of sound-absorbing, noise reduction can be preferably played, the volume of noise is greatly reduced.
