Description

A kind of motorcycle exhaust pipe

Technical field

The present invention relates to motorcycle accessories fields, and in particular to a kind of motorcycle exhaust pipe.

Background technique

Existing motorcycle exhaust pipe is mostly hollow cylinder shape, is built-in with silencer, before exhaust pipe nozzle with start Machine exhaust outlet connects, and the gas of engine discharge silencer in exhaust pipe and exhaust pipe is released from exhaust outlet.But existing exhaust Pipe is made of the metal material of stainless steel, and is mono-layer tube structure mostly, the gas warp that when motorcycle driving is discharged from engine The tube wall of stainless steel exhaust pipe conducts and keeps its surface temperature very high, can be to artificial at scald.

Motorcycle exhaust pipe is the important component of motorcycle, and the main effect of exhaust pipe is after engine combustion is discharged Exhaust gas.The exhaust gas of motorcycle emission sweeps along the carbon particle impurity of a large amount of pernicious gases to cause serious pollution to environment, If disposed not in time, over time, can greatly be endangered to people's lives and health care belt.

Meanwhile most of exhaust pipes are all made of aluminium production, but the thermal expansion coefficient of aluminium is larger, in addition exhaust pipe Vibration, the expansion with exhaust pipe aluminium, so loosening would tend to occur in the bolt and nut of fixed exhaust pipe in engine operation The phenomenon that, as exhaust pipe loosening will increase noise.

Summary of the invention

The purpose of the present invention is to provide a kind of motorcycle exhaust pipes, caused by the prior art above-mentioned multinomial scarce to solve It falls into.

A kind of motorcycle exhaust pipe, including exhaust pipe, cylinder exhaust outlet are threadedly coupled with exhaust pipe, the exhaust Pipe is externally provided with sound proof housing, is equipped with filter device in exhaust pipe, which includes tube wall filter and outlet end filter, institute Tube wall filter is stated in exhaust pipe, is connect with exhaust inside pipe wall, the tube wall filter ecto-entad includes supporting network, mistake Filter core, filter screen and filter layer, the outlet end filter be set to exhaust outlet end, the input end of the exhaust pipe with start Machine cylinder exhaust port is threadedly coupled, and the input end and cylinder exhaust outlet of exhaust pipe are equipped with clamp device, is gone back in exhaust pipe Equipped with silencer.

Preferably, the exhaust pipe is bipartial structure, and angle is 160 °, and the silencer is separately positioned on exhaust pipe two In the pipeline of intercept form, which is both ends wide-mouth, and the side wall of the structure of middle position osculum, silencer is equipped with sound attenuation hole.

Preferably, the clamp device includes casing, and casing is fixed on the outer wall of exhaust pipe input end, casing and engine Cylinder exhaust port is equipped with threaded hole in corresponding position, is bolted to connection.

Preferably, the exhaust pipe is equipped with tail gas content analyzer.

Preferably, the outlet end is honeycomb.

The present invention has the advantages that exhaust pipe is externally provided with sound proof housing, the noise that motorcycle awing manufactures can be eliminated, is subtracted Noise pollution in few city, tube wall filter includes supporting network, filtration core, filter screen and filter layer, multilayer mistake from inside to outside Motorcycle tail gas cleaning efficiency can be improved in filter, plays good filtration, reduces atmosphere pollution, outlet end end has added one to go out again Mouth end filter, plays multiple purifying, may filter that PM2.5 in tail gas, and prevention air quality reduces, and system is breathed in reduction crowd The generation for disease of uniting, exhaust pipe have bending curvature, and filter device filter efficiency can be improved, and exhaust pipe is equipped with tail gas content analysis Device, whether the pollutant load that can detecte tail gas is exceeded, and outlet end is honeycomb, can reduce air pressure when tail gas has been arranged, mention High safety, exhaust pipe are first threadedly coupled with cylinder exhaust outlet, are passing through casing and cylinder exhaust outlet spiral shell Bolt is fixed, and the direction of bolt and the direction of vibration of exhaust pipe are in plumbness, prevents bolt falling.

Specific embodiment

To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to Specific embodiment, the present invention is further explained.

As depicted in figs. 1 and 2, a kind of motorcycle exhaust pipe, including exhaust pipe 1 and filter device, exhaust pipe 1, which is externally provided with, to disappear Acoustic shell 11, filter device include tube wall filter 2 and outlet end filter 3, and tube wall filter 2 is set in exhaust pipe 1, with exhaust Inside pipe wall 6 connects, and 2 ecto-entad of tube wall filter includes supporting network 7, filtration core 8, filter screen 9 and filter layer 10, outlet end mistake Filter 3 is set to exhaust outlet end 4, and exhaust pipe is externally provided with sound proof housing 11, can eliminate the noise that motorcycle driving manufactures on the way, subtract Noise pollution in few city, tube wall filter include supporting network 7, filtration core 8, filter screen 9 and filter layer 10 from inside to outside, more Motorcycle tail gas cleaning efficiency can be improved in layer filtering, plays good filtration, reduces atmosphere pollution, outlet end end adds again One outlet end filter, plays multiple purifying, may filter that PM2.5 in tail gas, and prevention air quality is reduced, exhaled in reduction crowd The generation of desorption system disease.

As shown in Figure 1, exhaust pipe 1 is bipartial structure, angle is 160 °, and silencer 12 is separately positioned on exhaust pipe two-section In the pipeline of formula, which is both ends wide-mouth, and the side wall of the structure of middle position osculum, silencer 12 is equipped with sound attenuation hole, The sound that gas flowing issues can be reduced, noise is reduced.

As shown in figure 3, clamp device includes casing 13, casing 13 is fixed on the outer wall of exhaust pipe input end 16, casing 13 It is equipped with threaded hole in corresponding position with cylinder exhaust outlet 15, is fixedly connected by bolt 14, exhaust pipe 1 is first and starts Machine cylinder exhaust port 15 is threadedly coupled, and is fixed by casing 13 and 15 bolt of cylinder exhaust outlet, the direction of bolt 14 It is in plumbness with the direction of vibration of exhaust pipe, prevents bolt 14 from falling off.

It is worth noting that, exhaust pipe be equipped with tail gas content analyzer 5, can detecte tail gas pollutant load whether Exceeded, outlet end 4 is honeycomb, can reduce air pressure when tail gas has been arranged, improve safety.

As known by the technical knowledge, the present invention can pass through the embodiment party of other essence without departing from its spirit or essential feature Case is realized.Therefore, embodiment disclosed above, in all respects are merely illustrative, not the only.Institute Have within the scope of the present invention or is included in the invention in the change being equal in the scope of the present invention.
