Abstract

The invention discloses an automobile vent pipe with a super-strong sound-muffling function. The automobile vent pipe comprises a main pipe. The tail end of the main pipe is provided with two branch pipes in a branched mode, and the two branch pipes are in bilateral symmetry. An exhaust purifier is mounted on the main pipe. The gas inlet end of the main pipe is provided with a connecting flange. The tail end of each gas outlet pipe is provided with a dust cover. The main pipe, the branch pipes and the gas outlet pipes form a second-level sound-muffling system. The automobile vent pipe with the super-strong sound-muffling function is simple in structure and reasonable in design; through branching between the main pipe and the branch pipes and branching between the branch pipes and the gas outlet pipes, tail gas in the main pipe is distributed twice, vibration caused by too large airflow is greatly reduced, vibration of the vent pipe is reduced, and accordingly the good sound-muffling function is achieved; meanwhile, the automobile vent pipe with the super-strong sound-muffling function is novel in structure and remarkable in effect, also has a good dust prevention effect and has strong market competitiveness.

Description

A kind of automobile exhaust pipe with superpower silencing function
Technical field
The present invention relates to technical field of automobile, be specially a kind of automobile exhaust pipe with superpower silencing function.
Background technology
Automobile exhaust corrugated tube is also known as automobile exhaust pipe flexible pipe, and it is installed in the exhaustor between engine exhaust branch pipe and acoustic filter, and making whole gas extraction system is Flexible spacecraft, thus playing vibration and noise reducing, the convenient effect installed and extend the exhausting silencer system life-span. It is mainly used in Light-duty Vehicle, minicar and passenger vehicle, and its structure is that double-ply bellows is cladded with wire sets, and the structure of two ends straight section overcoat snap ring, for making soundproof effect more preferably, bellows interior can join telescopic joint or net. Material: main material is rustless steel SUS304, and cutting ferrule and adapter material can be rustless steel or aluminum-plated steel. Exhaustor is exhaust component very common on automobile, and its air inlet accesses since engine expellant gas, and discharges from the gas outlet of exhaustor. The gas outlet of existing automobile exhaust pipe is generally open, when the wind that knocks into the back is bigger, special automobile is in the local driving process that dust storm is bigger, it is possible to occur dust storm to pour in down a chimney into exhaustor, thus making the damage of coupled engines, even affect the runnability of whole automobile. It addition, automobile number increases quickly in recent years, incident traffic noise contamination phenomenon also becomes increasingly conspicuous. And the topmost noise of automobile is from the gas extraction system of automobile, i.e. motor vehicle exhaust emission noise, existing automobile exhaust pipe realizes reducing the effect of noise by installing deafener, but muffler structure is complicated and installs inconvenience.
Summary of the invention

A kind of automobile exhaust pipe with superpower silencing function of the present invention, its simple in construction, reasonable in design, by being responsible for and being in charge of, be in charge of and constitute repeatedly branch with escape pipe, make the tail gas in supervisor through twice shunting, substantially reduce the vibration owing to air-flow causes greatly very much, reduce the vibration of exhaustor itself, there is good silencing function; Meanwhile, adopt on supervisor and exhaust purifier is installed, it is possible to reduce the noxious gas emission in vehicle exhaust in air, cause atmospheric pollution, and exhaust purifier also has certain erasure effect, decreases sound pollution; It addition, described escape pipe end is provided with dust cover, it is ensured that at dusty wind weather, dust will not block exhaustor; Present configuration is novel, and effect is obvious, has the very strong market competitiveness.
Further, above-mentioned a kind of automobile exhaust pipe with superpower silencing function, described being in charge of is provided with fixed mount. Owing to exhaustor adopts twice grading design, exhaust emissions process easily produces vibration, growth over time, fracture phenomena, mounting and fixing support is there will be, it is ensured that stablizing of structure between each structure, do not have tube burst etc. and damage phenomenon, extend the service life of exhaustor.
Further, above-mentioned a kind of automobile exhaust pipe with superpower silencing function, the exhaust end of described escape pipe is provided with fixing edgewise.
Further, above-mentioned a kind of automobile exhaust pipe with superpower silencing function, described dust cover is provided with snap close, and described snap close is arranged on the end of escape pipe by locked fixing edgewise.
Further, above-mentioned a kind of automobile exhaust pipe with superpower silencing function, described snap close is provided with 2��4, is evenly distributed on dust cover surrounding.
Further, above-mentioned a kind of automobile exhaust pipe with superpower silencing function, it is provided with spring leaf inside described dust cover. Being provided with spring leaf inside dust cover, described spring leaf can play counteracting force, it is ensured that dust cover can be stably fixed to the end of escape pipe under the effect of snap close, does not have the phenomenon of landing.
Further, above-mentioned a kind of automobile exhaust pipe with superpower silencing function, described exhaust purifier is ternary catalyzing unit. Can effectively remove the harmful gass such as CO, HC and NO in vehicle exhaust, reduce the generation of atmospheric pollution.
Further, above-mentioned a kind of automobile exhaust pipe with superpower silencing function, described supervisor, be in charge of with escape pipe inside scribble zinc coat. It is coated with by zinc coat in pipeline, it is possible to ensure to be not result in corrosion phenomenon under the environment of pipeline long-time high temperature again, simultaneously because with part steam in tail gas, zinc coat ensure that the antiseptic property of exhaustor, effectively extend the service life of exhaustor.
Further, above-mentioned a kind of automobile exhaust pipe with superpower silencing function, the thickness of described zinc coat is 2��4 ��m.
Technique scheme can be seen that, there is advantages that described a kind of automobile exhaust pipe with superpower silencing function of the present invention, its simple in construction, reasonable in design, by being responsible for and being in charge of, be in charge of and constitute repeatedly branch with escape pipe, make the tail gas in supervisor through twice shunting, substantially reduce the vibration owing to air-flow causes greatly very much, reduce the vibration of exhaustor itself, there is good silencing function; Meanwhile, adopt on supervisor and exhaust purifier is installed, it is possible to reduce the noxious gas emission in vehicle exhaust in air, cause atmospheric pollution, and exhaust purifier also has certain erasure effect, decreases sound pollution; It addition, described escape pipe end is provided with dust cover, it is ensured that at dusty wind weather, dust will not block exhaustor; Present configuration is novel, and effect is obvious, has the very strong market competitiveness.
