Summary of the invention
To the above-mentioned deficiency that existing technology exists, the purpose of this invention is to provide a kind of can in irritate the noise eliminator of motorcycle that the two catalyst of band of catalyst are installed after lacquer or the chromium plating again.
Technological scheme of the present invention is achieved in that the noise eliminator of motorcycle of the two catalyst of band, comprises muffler body leading portion, silencing apparatus dividing plate, preceding catalytic converter, back catalytic converter and catalyst sleeve pipe; The silencing apparatus dividing plate is fixed in the muffler body leading portion, and preceding catalytic converter is installed in the muffler body leading portion through the catalyst sleeve pipe with the back catalytic converter; The silencing apparatus dividing plate is provided with the hole, and the afterbody of back catalytic converter is placed in the hole, and catalyst sleeve pipe front portion passes from muffler body leading portion front port.It is characterized in that: the internal diameter and the catalyst sleeve pipe maximum outside diameter of said muffler body leading portion front port are suitable.
Said catalyst sleeve pipe two ends all have the enlarging structure, and catalyst sleeve pipe maximum outside diameter is positioned at enlarging place.
Be provided with the guiding flange around the hole on the said silencing apparatus dividing plate, the guiding flange is towards afterbody.Said back catalytic converter be provided with the silencing apparatus dividing plate on the corresponding guide cylinder in hole, the guide cylinder tail end has the closing in structure.The design of guiding flange and guide cylinder is beneficial to and is installed in catalyst in the muffler body leading portion from the front toward caudal directions.
The enlarging of said catalyst sleeve pipe front end has the closing in structure, and closing in internal diameter and outlet pipe external diameter are suitable.Can use original outlet pipe thus and need not it be changed, so adaptability is strong.
After the present invention improves acoustic wave filter structure; In the problem that guarantees to have solved under the prerequisite that cost does not improve silencing apparatus chromium plating and interior filling lacquer, can in irritate after lacquer or the chromium plating assembly welding catalyst again, thereby guarantee that catalyst is not etched and covers; And then the changing effect of assurance catalyst; Greatly improved the producing feasibility of silencing apparatus, and simple in structure, workable.
