Description
Technical field
The invention belongs to duct equipment technical fields, and in particular to automobile silencing exhaust pipe.
Background technology
At present, with the continuous development of China's economy, motor vehicle has become to be popularized very much, and automobile has come into thousand ten thousand
Family, it is industrial also very extensive using ground with agriculturally motor vehicle.But since China's road traffic does not obtain but accordingly
Development, largely causes that road transport is crowded, in the quality problems plus motor vehicle design problem itself, manufacture and makes
The produced various failure in, along with many people do not observe traffic rules and regulations, so causes accident to occur again and again.It is many motor-driven
Vehicle accident can cause motor vehicle to burn or even motor vehicle can be made to explode, one major reason, be exactly exhaust pipe it is not heat-insulated or every
The effect of heat is poor, and the temperature for causing exhaust pipe is excessively high, can cause ignite oil pipe or fuel tank oil leak, triggers motor vehicle burning or quick-fried
It is fried.The principle of exhaust pipe noise reduction be by being reflected to exhaust airstream air-flow, the measures such as scattered, expansion, make the flow velocity of exhaust airstream
It reduces.So as to achieve the purpose that noise reduction.In addition, the development with automotive energy-saving emission-reducing, it is desirable that automobile reduces noise, energy saving
Consumption.Automobile exhaust pipe is one of important component in automobile exhaust system, the atmosphere pollution caused by motor vehicle exhaust emission and
Noise, it has also become one of important sources of city environmental pollution.The heat insulation of exhaust pipe is poor, makes troubles to client's use.
For example, automobile exhaust pipe overheat can make a pipeline leak, the volatilization that can also accelerate fuel oil causes to waste.Therefore, how vapour is researched and developed
Vehicle silencing exhaust pipe, has important practical significance.
The content of the invention
For problems of the prior art, it is an object of the invention to provide automobile silencing exhaust pipes.
The technical solution that the present invention takes is：
Automobile silencing exhaust pipe, including interconnected four air inlet pipe and an air outlet pipe, the link position of air inlet pipe is arc
Shape face, air inlet pipe are located at the one side opposite with air outlet pipe and are mutually parallel, and the air inlet pipe is connected with filter chamber, leads in filter chamber
It crosses exhaust manifold with outlet silencing cavity to be connected, metal netting is provided in outlet silencing cavity, the outlet silencing cavity passes through connection
Pipe is connected with echo chamber, and echo chamber one side is provided with bellows, and it is short that bellows both sides are provided with flange, connection short tube and fixation
Pipe, bellows are connected with each other with echo chamber, and the echo chamber is connected by air outlet pipe with outlet mouth of pipe, and outlet silencing cavity upper end is set
Fixed plate is equipped with, fixed plate is connected with each other by bolt and air outlet pipe, and cooler is provided on the exhaust tube body.
Further, the end of each air inlet pipe is both provided with square installing plate.
Further, the connection short tube is mutually permanently connected with fixed short tube.
Further, the filter chamber is internally provided with filter layer.
Further, the outlet silencing cavity is arranged to cochlea helical structure.
Beneficial effects of the present invention are：
The outlet silencing cavity of exhaust pipe and echo chamber cooperate to design in the present invention realizes echo and noise reduction work, gold respectively
Belonging to netting has the flexibility of height with anticorrosive, can effectively absorb noise and vibrations, it is therefore prevented that the thermal deformation of discharge duct,
Additionally by filter layer is set to realize filtering function, there is high-speed and high-efficiency, clean and safe, low cost, easy care, cooler avoids
High temperature during due to work makes the stress generated inside installing plate, extends service life.
Specific embodiment
Automobile silencing exhaust pipe, including interconnected four air inlet pipe and an air outlet pipe, the link position of air inlet pipe
For arcwall face, air inlet pipe is located at the one side opposite with air outlet pipe and is mutually parallel, and the air inlet pipe is connected with filter chamber, filter chamber
It is interior to be connected by exhaust manifold with outlet silencing cavity, metal netting is provided in outlet silencing cavity, the outlet silencing cavity passes through
Communicating pipe is connected with echo chamber, and echo chamber one side is provided with bellows, and bellows both sides are provided with flange, connection short tube and fixation
Short tube, bellows are connected with each other with echo chamber, and the echo chamber is connected by air outlet pipe with outlet mouth of pipe, outlet silencing cavity upper end
Fixed plate is provided with, fixed plate is connected with each other by bolt and air outlet pipe, and cooler is provided on the exhaust tube body.
Further, the end of each air inlet pipe is both provided with square installing plate.
Further, the connection short tube is mutually permanently connected with fixed short tube.
Further, the filter chamber is internally provided with filter layer.
Further, the outlet silencing cavity is arranged to cochlea helical structure.
The above is not limitation of the present invention, it should be pointed out that：Come for those skilled in the art
It says, on the premise of essential scope of the present invention is not departed from, several variations, modifications, additions or substitutions can also be made, these improvement
Protection scope of the present invention is also should be regarded as with retouching.
