Abstract
The utility model provides an exhaust pipe of automobile, including the blast pipe body, blast pipe body right -hand member is a coherent head of connecting the engine, and the left end is used for the air out head that gives vent to anger, and crooked shape that the blast pipe body was established according to automobile domain wiring orientation is equipped with three way catalyst converter and damping device in the end section part of blast pipe body, and last the overlapping of air out head has the dust cover, near coherent first of blast pipe body is equipped with the filter screen. This blast pipe adopts outer tube and inner tube bilayer structure to the acoustical panel is equipped with, the waste discharge noise of gas of car can be further reduces, adopt the wind cap, prevent that the sand blown by the wind from flowing backward into the blast pipe to the prevention is to the damage of engine, outer tube and inner tube are equipped with the insulating layer, can improve the thermal -insulated effect of blast pipe, prevent high temperature and the oil pipe or the oil tank oil leak of leading to igniting of blast pipe.
Description
Technical field
The utility model belongs to technical field of automobile, particularly a kind of automobile exhaust pipe.
Background technique
In recent years, along with the development of China's economy, huge numbers of families come into by automobile.Vehicle exhaust has become the No.1 pollution sources of a lot of central cities environmental protection.The power engine of current most of automobile is internal-combustion engine, can discharge a large amount of high-temperature tail gas during internal combustion engine and produce noise, but there is heat insulation or not heat insulation weak effect in motor vehicle exhaust, the temperature of outlet pipe can be caused too high, cause ignite oil pipe or fuel tank leakage of oil, cause Motor Vehicle burning.In addition, along with the development of automotive energy-saving emission-reducing, how effectively reducing the exhaust sound of motor, and high-temp waste gas can be made to discharge safely and effectively, is also the test to automobile industry.Usually, traditional automobile exhaust system realizes noise elimination noise reduction by fixing a silencer, but acoustic wave filter structure is complicated, and there is the unfavorable factor of installing inconvenience; And automobile is as in the place traveling that dust storm is larger, dust storm also may occur and pour in down a chimney into outlet pipe, thus make the damage of coupled engines, even affect the ride quality of whole automobile.
Model utility content
For the deficiencies in the prior art, the invention provides that a kind of cost of production is low, good heat-insulation effect, can also effectively prevent dust storm from pouring in down a chimney, can reduce simultaneously the automobile exhaust pipe of noise.
For realizing goal of the invention, the technological scheme that the present invention takes is:
A kind of automobile exhaust pipe, comprise outlet pipe body, described outlet pipe body right-hand member be connecting engine connect gas head, left end is the head of giving vent to anger for giving vent to anger, the curved shape that outlet pipe body is set as according to automobile chassis wiring direction, the end segment parts of outlet pipe body is equipped with ternary catalyzing unit and damping device, going out cover in a fit of anger has dust-proof cover, and connecing near gas head of described outlet pipe body is provided with filter screen.
As preferably, described outlet pipe body comprises outer tube and interior pipe, and described outer tube is fixedly connected with by multiple acoustical panel with interior pipe, forms a cavity, be provided with filter screen in each cavity between every two acoustical panels.
As preferably, in described acoustical panel, be filled with silencing cotton.
As preferably, with thermal-protective coating on described outer tube wall, inner tube wall is provided with thermal-protective coating.
The beneficial effects of the utility model are embodied in:
1. adopt outer tube and interior pipe double layer construction, and be provided with acoustical panel, the noise of automobile waste air can be reduced further;
2. adopt windshield, prevent dust storm from pouring in down a chimney into outlet pipe, thus the damage of prevention to motor;
3. outer tube and interior pipe are provided with thermal-protective coating, can improve the effect of heat insulation of outlet pipe, prevent the temperature of outlet pipe too high and cause ignite oil pipe or fuel tank leakage of oil.
Accompanying drawing explanation
Fig. 1 is the structural representation of outlet pipe of the present utility model;
Fig. 2 is the sectional view of the outlet pipe body in outlet pipe of the present utility model;
Wherein, 1. outlet pipe body, 1a. connects gas head, and 1b. gives vent to anger head, 2. ternary catalyzing unit, 3. damping device, 4. dust-proof cover, 5. filter screen, 6. acoustical panel, 7. silencing cotton, 8. filter screen, 9. thermal-protective coating, 10. thermal-protective coating.
Embodiment
Below in conjunction with specific embodiments and the drawings, the utility model is described.
A kind of automobile exhaust pipe as shown in Figure 1 and Figure 2, comprise outlet pipe body 1, described outlet pipe body right-hand member be connecting engine meet gas head 1a, left end is the 1b that gives vent to anger for giving vent to anger, the curved shape that outlet pipe body is set as according to automobile domain wiring direction, the end segment parts of outlet pipe body is equipped with ternary catalyzing unit 2 and damping device 3, on a 1b that gives vent to anger, cover has dust-proof cover 4, and connecing near gas head of described outlet pipe body is provided with filter screen 5; Described outlet pipe body comprises outer tube 11 and interior pipe 12, described outer tube 11 is fixedly connected with by multiple acoustical panel 6 with interior pipe 12, silencing cotton 7 is filled with in described acoustical panel, a cavity is formed between every two acoustical panels, filter screen 8 is provided with in each cavity, with thermal-protective coating 9 on described outer tube wall, inner tube wall is provided with thermal-protective coating 10.
Above embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that the common engineers and technicians in related domain make the technical solution of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
