Description
Technical field
The present invention relates to automotive field, specifically a kind of automobile exhaust pipe with noise reduction and antirust function of automobile exhaust system.
Background technique
Along with the development of China's economy, it is very universal that Motor Vehicle becomes, present each family nearly all has an automobile, people are when selecting automobile, not only focus on the appearance of automobile, the safety and stability of automobile and environmental consciousness are also extremely valued, in recent years, urban motor vehicle increases very fast, incident traffic noise pollution environmental phenomenon also becomes increasingly conspicuous, automobile is noise pollution to the harm that environmental protection is maximum, investigation shows, motor vehicle noise accounts for 85.5% of urban traffic noise, along with the development of automotive energy-saving emission-reducing, require that automobile reduces noise, energy saving consumes.And the topmost noise of automobile is from the vent systems of automobile, i.e. motor vehicle exhaust emission noise, in order to reduce motor vehicle exhaust emission noise, meet the requirement of automobile environment-protection, traditional automobile exhaust system realizes noise elimination noise reduction by fixing a silencer, but acoustic wave filter structure is complicated, and install also inconvenient.
Meanwhile, the Motor Vehicle such as automobile in use, outlet pipe be one get rusty easily damage parts, particularly those mainly city short distance travel automobile, outlet pipe get rusty damage phenomenon more outstanding.Study by analysis, find outlet pipe get rusty easily most damage major reason, except the material with outlet pipe generally understood is relevant, when another major reason is because of each automobile running, owing to just starting working, whole section of outlet pipe or temperature is lower, the damp and hot waste gas that motor ejects through colder outlet pipe, can in outlet pipe particularly the silencing apparatus position of outlet pipe meet cold and produce condensed water.If automobile running time long enough, then outlet pipe slowly heating under the heating of waste gas, the condensed water produced can be fallen by heating evaporation, if but automobile does short distance to travel in city, running time long just end travels and flame-out parking, then outlet pipe does not also reach enough temperature, the condensed water produced also just also is not evaporated and remains in outlet pipe particularly in silencing apparatus, and the gases such as the sulfur dioxide of water in automobile exhaust gas, nitrogen dioxide can produce acid after being combined, corrode outlet pipe and make its damage that gets rusty easily.
summary of the invention.
Goal of the invention: in order to solve the deficiencies in the prior art, the invention provides a kind of structure simple, and working stability is reliable, conveniently can install and remove, have the automobile exhaust pipe of noise reduction and antirust function.
Technological scheme: in order to realize above object, a kind of automobile exhaust pipe with noise reduction and antirust function of the present invention, it comprises: outlet pipe body, silencing cotton, arc shaped surface, water-leaking hole, mounting hole and noise elimination portion, one end of described outlet pipe body is conical surface body, conical surface body is provided with mounting hole, the other end of outlet pipe body is exhaust outlet, turning in the middle of outlet pipe body is noise elimination portion, arc shaped surface is provided with in outlet pipe body, the middle of adjacent two arc shaped surfaces above outlet pipe body interior is provided with silencing cotton, by adding silencing cotton in outlet pipe body interior, for adsorbing noise and eliminating, the erasure effect of device can be improved, the middle of adjacent two arc shaped surfaces below outlet pipe body interior is provided with water-leaking hole, when automobile running terminates to stop, if short distance travels, when the condensed water that outlet pipe produces also is not remained in outlet pipe by fully evaporating, condensed water will directly flow out from the water-leaking hole outlet pipe, can not be accumulated in outlet pipe, reduce the condensed water in outlet pipe and the sulfur dioxide in automobile exhaust gas, the acid attack outlet pipe produced after the gases such as nitrogen dioxide combine makes its impaired situation that gets rusty easily occur.
As present invention further optimization, described outlet pipe body is " Z " shape, adds arc shaped surface in outlet pipe body interior, for increasing the area of contact with air, increases the area of contact with noise, and carries out counteracting process by " Z " shape structure to noise.
As present invention further optimization, internal surface and the outer surface of described outlet pipe body are provided with electrodeposited coating, described electrodeposited coating is nickeling layer, promote resistance to corrosion and the abrasive resistance of outlet pipe body, effectively can prevent from water-leaking hole, do not leak the water removed and occur in the situation of outlet pipe body internal corrosion outlet pipe.
As present invention further optimization, through mounting hole, outlet pipe body is fixed on the tracheae of automobile by bolt or screw, described bolt or screw are coated with one deck nickel, increase resistance to corrosion and the abrasive resistance of bolt, effectively can prevent from being often parked in outdoor automobile and run into dew or when raining heavyly, the situation that bolt is corroded occurs.
Beneficial effect: a kind of automobile exhaust pipe with noise reduction and antirust function of the present invention, compared with prior art, has the following advantages:
1, by adding silencing cotton in outlet pipe body interior, for adsorbing noise and eliminating, the erasure effect of device can be improved;
2, add arc shaped surface in outlet pipe body interior, for increasing the area of contact with air, increase the area of contact with noise, and by " Z " shape structure, counteracting process is carried out to noise;
3, bottom outlet pipe, water-leaking hole is added, when automobile running terminates to stop, if short distance travels, when the condensed water that outlet pipe produces also is not remained in outlet pipe by fully evaporating, condensed water will directly flow out from the water-leaking hole outlet pipe, can not be accumulated in outlet pipe, the acid attack outlet pipe produced after the gas such as the sulfur dioxide of condensed water in automobile exhaust gas, nitrogen dioxide reduced in outlet pipe is combined makes its impaired situation that gets rusty easily occur;
4, by plating one deck nickel in outlet pipe body interior and outside, promoting resistance to corrosion and the abrasive resistance of outlet pipe body, effectively can prevent from water-leaking hole, do not leak the water removed and occur in the situation of outlet pipe body internal corrosion outlet pipe;
5, the bolt by being connected with the tracheae on automobile by outlet pipe body plates one deck nickel, increases the resistance to corrosion of bolt and abrasive resistance, effectively can prevent from being often parked in outdoor automobile and run into dew or when raining heavyly, the situation that bolt is corroded occurs.
