Description
Technical field
The present invention relates to automobile exhaust sound-attenuating system field, be specifically related to a kind of silencer muffler partition plate and silencing apparatus.
Background technique
The acoustic wave filter structure of existing band dividing plate generally adopts the dividing plate of the complete contact type with inwall, namely selects the dividing plate mated completely with housing section, by dividing plate and housing interference fit, or is completed the assembling of dividing plate and housing by the mode of resistance welding.
Because of dividing plate and the whole peripheral contact of housing, even if by interference fit or resistance welding mode, but owing to manufacturing factor or service wear, local location is still had to there will be the slight gap of elongate, the meeting turbulization when high-speed gas passes through gap by air-flow, and then produce ear-piercing howling, not only have impact on acoustic attenuation performance, and add the source of noise.Therefore, market is badly in need of a kind of diaphragm structure that effectively can solve this problem of howling that slight gap produces between dividing plate and housing.
Summary of the invention
The present invention aims to provide a kind of silencer muffler partition plate and uses the silencing apparatus of this dividing plate, and the present invention can avoid air and produce ear-piercing howling by during slight gap between dividing plate and housing, reduce further noise, has excellent acoustic attenuation performance.
Silencer muffler partition plate of the present invention, the outer of described dividing plate is provided with at least three boss.
Described dividing plate is provided with air inlet pipe hole, pore of giving vent to anger, air dispelling hole.
Described dividing plate is preferably circular, also can be designed to other shape according to the silencing apparatus shape of correspondence and structure, not as square, and rhombus etc.
When baffle design is circular, described boss is evenly distributed on the outer of dividing plate circumferentially.
A kind of silencing apparatus of the present invention, comprises housing and dividing plate, and described silencer muffler partition plate outer is provided with at least three boss, and boss contacts with interference fit with inner walls, forms space between the part of dividing plate outer except boss and housing.
The housing of described silencing apparatus comprises front cover, rear end cover, and described front cover is provided with suction port, and described rear end cover is provided with air outlet; At least one piece of dividing plate is installed in housing, dividing plate is provided with air inlet pipe hole, pore of giving vent to anger, air dispelling hole; Air dispelling hole on each piece of dividing plate and space are jointly as the loose gas part after the installation of silencing apparatus internal partition; Air inlet pipe hole on dividing plate and suction port alignment, the pore of giving vent to anger on dividing plate aligns with air outlet; Suction tude, through after the air inlet pipe hole on each piece of dividing plate, is communicated with suction port, and steam outlet pipe, through after the pore of giving vent to anger on each piece of dividing plate, is communicated with air outlet.
The housing of described silencing apparatus is preferably cylindrical, and described dividing plate is preferably circular accordingly.The housing of described silencing apparatus can also be designed to cuboid, prism etc. as required, and dividing plate is designed to square and rhombus etc. accordingly.
When the housing design of silencing apparatus be cylindrical, described dividing plate be designed to circle accordingly time, described boss is evenly distributed on the outer of dividing plate circumferentially.
Key point of the present invention is to be arranged at the boss on dividing plate outer, during assembling, dividing plate is contacted with the interference fit of housing by boss structure, dividing plate only have projection section and housing close contact, space is formed between all the other most of outer and cylindrical shells, the space of this part coordinates air dispelling hole to carry out design consideration as common loose gas perforated area, such design, just perfectly can solve the problem of the howling produced because of slight gap between dividing plate and housing, also can not cause the reduction of erasure effect simultaneously because of extra space.
Not easily there is the fine gap producing howling in the part that boss of the present invention is connected with housing, reason is as follows:
1. boss and body contact area few, more easily fit.
2. boss and housing are interference fit, and centering property is good, and bearing capacity is high, and can withstand shocks load;
3. shell body wall is thin, easily produces resiliently deformable, makes the laminating of boss and housing tightr;
In sum, the present invention solves the problem causing howling to produce because there is elongate gap between dividing plate and housing from design angle, thus make soundproof effect better, manufacture up-to-standard rate higher, quality of product is more stable, and silencer muffler partition plate provided by the invention is applicable to the silencing apparatus of all kinds of band dividing plate.
