Description

Motorcycle triangle silencer

Technical field

The present invention relates to a kind of silencing apparatus, and in particular to a kind of motorcycle triangle silencer.

Background technology

It is growing with scientific and technological level, and the raising of people's level, various motor vehicles are as a kind of common friendship Logical instrument is widely applied in daily life, and motorcycle is a kind of.Since the factor of motorcycle power can produce Bigger noise, various noise elimination equipment are widely applied on motorcycle, to achieve the purpose that to reduce noise.

Noise eliminator of motorcycle is a kind of to allow air-flow by being the important spare part on motorcycle and the noise reduced device that declines One of.The quality of Muffler Performance not only influences the size of motorcycle noise, but also the power to engine, oil consumption, moment of torsion etc. Performance has large effect.

At present, noise eliminator of motorcycle generally comprises cone cylinder and straight tube, and the rear end of cone cylinder is connected with the front end of straight tube, straight tube The fixed tail-hood in rear end, and plurality of partitions is set in straight tube, form the several small anechoic rooms connected by conduit, high-decibel The noise of value is progressively spread by several small anechoic rooms, attenuation portions noise decibel value, but in this class formation, noise is direct The noise elimination chamber interior walls that sheet metal surrounds are hit, cause vibration noise larger, so what is exported after the processing of such silencer makes an uproar Sound is generally still up to more than 80 decibels, forms noise pollution.And the characteristics of silencer of said structure be frequency of noise elimination section compared with Width, but sound deadening capacity deficiency, while can not decay for some noise peak frequencies, so cannot preferably be eliminated the noise Effect., can be because of insufficient space on the motorcycle of some models furthermore the straight drum part of noise eliminator of motorcycle is mostly circular cross-section And install limited.

The afterbody of noise eliminator of motorcycle is typically provided tail pipe, which is arranged on the tail end of silencer, and the front end of tail pipe Stretch into silencer, the exhaust gas that motorcycle engine acting produces is discharged after silencer noise reduction from tail pipe.In motorcycle starting When, due to weather reason or in the case where igniting repeatedly fails to light, in-engine combustion mixture, which is known from experience, to be entered In silencer, when lighting a fire successfully, this part burning mixture is ignited, and flame is produced, when the flammable mixing in silencer When gas is more, the flame of generation can be sprayed from tail pipe.If motorcycle be afield, forest or other inflammable local rows Sail, the flame of ejection easily triggers fire.In addition, silencer is after prolonged use, its inner cylinder has carbon distribution generation, and carbon distribution is in height Mars can be produced under the action of warm exhaust gas, is sprayed from tail pipe, also becomes the reason for triggering fire, it is therefore desirable to set in silencer Catalyst is put, effective purified treatment can be carried out to the gas for entering silencer initial stage to be started in engine, while having flame Flame is obstructed outside tail pipe using flame arrest net when reaching tail pipe front end.

The content of the invention

The present invention seeks in order to solve the above technical problems, providing that a kind of output noise decibel value is low, noise elimination effect is good, useless Gas purification is complete, does not have the motorcycle triangle silencer of flame ejection.

To reach above-mentioned purpose, the technical solution adopted by the present invention is：A kind of motorcycle triangle silencer,

Including silencer cylinder, the both ends of the silencer cylinder connect exhaust pipe and tail pipe respectively, on the exhaust pipe Equipped with the anti-borrosion hole connected with lubricant reservoir, the silencer cylinder is welded by straight tube and cone cylinder, the straight tube it is transversal Face is triangle, and asbestos acoustic tube and steel mesh cylinder are set with the straight tube；

The rear end of the exhaust pipe is equipped with one piece of partition plate, institute from cone cylinder nozzle insertion silencer cylinder in the straight tube The side for facing exhaust pipe for stating partition plate is equipped with asbestos sound absorption pad, and the partition plate is equipped with communicating pipe, the rear end of the exhaust pipe Connect with partition plate, and correspond on the partition plate at exhaust pipe and be equipped with air-flow via, the tube wall of the exhaust pipe rear end is equipped with A plurality of stomatas；

The front end of the tail pipe is from straight tube rear end insertion silencer cylinder, and the front end outer side of the tail pipe is arranged with and disappears Flame net；

Cone cylinder partition plate is equipped with the cone cylinder, the exhaust pipe is stretched into straight tube through the cone cylinder partition plate, the cone cylinder every Plate is equipped with insertion tube, and the cone cylinder inner wall of the cone cylinder partition plate and its front end, which encloses, is set as resonator.

Wherein, the exhaust pipe being inserted into the silencer cylinder is equipped with catalyst.

Further, the exhaust pipe being inserted into the silencer cylinder is equipped with the catalyst of two series connection, is set between two catalyst There is secondary air-supplying device, waste gas purification is more thorough.

Wherein, the straight tube is wherein fixed with the outside of a seamed edge along its axially extending shield.

Wherein, the side opposite with the shield of the straight tube is equipped with installation lifting lug.

Wherein, the outer sheath of the exhaust pipe is equipped with anti-scald cover.

Since above-mentioned technical proposal is used, the present invention this have the advantage that compared with prior art：

1. the present invention is provided with asbestos sound absorption structure in straight tube inner wall, partition plate side, exhaust gas can be farthest absorbed The noise produced in silencer cylinder, noise elimination effect are good.

2. the present invention is provide with flame arrest net in the front end of tail pipe, prevent flame from being sprayed from tail pipe, avoid that fire occurs.

3. the present invention sets resonator in cone cylinder, can decay for some noise peak frequencies, effectively to reduce The exhaust noise of motorcycle.
