Description

A kind of automobile exhaust and silencing means
Technical field
The present invention is a kind of automobile exhaust pipe, more particularly to a kind of automobile exhaust and silencing means.
Background technology
Also fine worries are brought while the generation of automobile brings convenient, such as caused by motor vehicle exhaust emission Air pollution problems inherent, car noise also should not be underestimated greatly very much to the interference that resident living is brought, existing exhaust system kind Class also has a lot, but more traditional in design structure, and loss rate ratio is very fast in addition, and the useful life of finished product is shorter, It is accomplished by changing after a period of time use, otherwise soundproof effect has just beaten very big discount, and the noise reduction principle typically used is By porous mode, the mode of sound-absorbing material is also filled, but vehicle exhaust temperature is higher, and sound-absorbing will be made for a period of time Material surface formation hardening and puigging or carbon distribution, have a great impact to sound-absorbing effect.
The content of the invention
Goal of the invention：For above-mentioned prior art and the deficiency of product, the present invention provides a kind of automobile exhaust pipe and noise reduction Device, the present invention has good muffling effect, and service life is long, simple in construction, easy-maintaining and unpick and wash feature.
Technical scheme：The invention discloses in a kind of automobile exhaust pipe and silencing means, including air inlet pipe outer tube, air inlet pipe Pipe, hush pipe, noise elimination chamber, acoustical lining, connecting spring, connecting tube, filtering chamber and escape pipe, described air inlet pipe outer tube Inside is provided with air inlet pipe inner tube, between described air inlet pipe outer tube and air inlet pipe inner tube in vacuum welding, with described air inlet pipe Pipe is connected with hush pipe, and noise reduction chamber is provided with inside described hush pipe, and described noise reduction chamber is fixed on by connecting spring Inside hush pipe, the connecting spring cavity of three floor acoustical lining, noise elimination chamber and hush pipe is provided with described muffler chamber room Interior to be filled with sound-absorbing material, the other end of described noise elimination chamber is connected by three connecting tubes with filtering chamber, described mistake Filter chamber indoor location has two layers of screen pack, and the other end of filter is connected with escape pipe.
Further, described sound-absorbing material has three layers, is followed successively by stephanoporate steel plate, steel fibre plate, acoustical cotton；
Further, multipath pipeline is used inside described connecting tube；
Further, described screen pack is asbestos material, and described screen pack has in the middle of double-layer structure, two layers of asbestos gauge Provided with ceramic pore filter.
Beneficial effect：A kind of automobile exhaust pipe and silencing means of the present invention, by setting air inlet pipe outer tube and disappearing Sound chamber, and filled by spring connection and vacuum, the vibrations of exhaust intraductal atmospheric pressure and the generation of noise are reduced well, are reached Arrived good noise reduction and erasure effect, in addition, the present invention is additionally provided with filter, reach further vehicle exhaust particle and The entrance of outside debris, causes automotive ignition failure etc., with very strong practicality, while also enhancing making for automobile exhaust pipe Use the life-span.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
