Abstract
The invention discloses an automobile noise reduction exhaust pipe which comprises an exhaust pipe main body. The two ends of the exhaust pipe main body are respectively an air connecting end communicated with an engine and an air outlet end for exhaust. The automobile noise reduction exhaust pipe is characterized in that a silencer is arranged between the air connecting end and the air outlet end, the exhaust pipe main body is further provided with a heat insulation layer, the heat insulation layer is made of a foam material or a filter material, and a temperature sensor is arranged on the surface of the one side of the heat insulation layer fixed with the exhaust pipe main body and is communicated with a controller of a cooling system. The automobile noise reduction exhaust pipe has the advantages of being simple in structure, high in practicality and good in noise reduction effect.
Description
Technical field
The present invention relates to auto parts machinery, specifically a kind of automobile noise reduction outlet pipe.
Background technique
Outlet pipe is installed between engine exhaust branch pipe and silencing apparatus, makes whole vent systems be Flexible spacecraft, thus plays vibration and noise reducing, the convenient effect of installing and extending the exhausting silencer system life-span.Outlet pipe is mainly used in Light-duty Vehicle, minicar and passenger vehicle, motorcycle, and exhaust pipe structure covers wire sets outside double-ply bellows, and the structure of two ends straight section overcoat snap ring, for making soundproof effect better, bellows interior can join slip joint or net.The main material of outlet pipe is stainless steel, and cutting ferrule and adapter material can be stainless steel or Aluminium Coated Steel.
In prior art, usually there are some potential safety hazards because of temperature overheating in outlet pipe, and dust removing effects is not fine, and thermal insulation is poor, fixes the situations such as dumb, therefore, be necessary to provide a kind of outlet pipe, to solve deficiency of the prior art.
Summary of the invention
According to the technical problem of above-mentioned proposition, and provide a kind of automobile noise reduction outlet pipe.The present invention mainly utilizes in outlet pipe main body, to set up thermal-protective coating and temperature transducer and silencing apparatus, thus plays the effect of noise reduction, temperature-controllable.
The technological means that the present invention adopts is as follows:
A kind of automobile noise reduction outlet pipe, comprise outlet pipe main body, the two ends of described outlet pipe main body be respectively be connected with motor connect gas end and the outlet side for being vented, it is characterized in that: be provided with silencing apparatus at the described middle part connecing gas end and described outlet side, described outlet pipe main body is also provided with thermal-protective coating, described thermal-protective coating adopts foam or Fiber Materials to make, the side surface that described thermal-protective coating and institute's outlet pipe main body are fixed is provided with temperature transducer, and described temperature transducer is connected with the controller of cooling system.
As preferably, described silencing apparatus is arranged in outlet pipe main body described in the side near outlet side.
As preferably, one section of described outlet pipe main body that described silencing apparatus is connected with described outlet pipe main body is telescopic pipeline.
Comparatively prior art is compared, and outlet pipe main body provided by the invention is provided with silencing apparatus, its body is also provided with thermal-protective coating, by temperature transducer, temperature is passed to cooling system, by the rising of cooling system control temperature; In addition, adopt telescopic pipeline, the effect of further noise elimination noise reduction can be played.
It is simple that the present invention has structure, and practical, the advantages such as noise reduction sound-deadening is effective, the present invention extensively can promote in automobile exhaust pipe field for the foregoing reasons.
