Abstract

The invention provides a silencer clapboard and a silencer. At least three lug bosses are arranged on the outer edge of the clapboard, and the clapboard is provided with an air inlet pipe hole, an air outlet pipe hole and air venting holes and is connected trough the in an interference fit and contact between the lug bosses and the shell. The silencer comprises the shell and the clapboard, wherein the at least three lug bosses are arranged on the outer edge of the silence clapboard, the lug bosses are in interference fit and contact with the inner wall of the shell, and a gap is formed between a part, except for the lug bosses, on the outer edge of the clapboard and the shell. According to the silencer clapboard and the silencer, the gap is reserved between the part, except for the lug bosses, on the outer edge of the clapboard and the shell, the harsh whistler generated when air passes through the small gap between the clapboard and the shell is avoided, the excellent sound proofing property is ensured, so that the manufacturing yield is high, and the product quality is stable; and the silencer clapboard is suitable for various silencers with clapboards.

Description

A kind of silencing apparatus dividing plate and silencing apparatus
Technical field
The present invention relates to automobile exhaust sound-attenuating system field, be specifically related to a kind of silencing apparatus dividing plate and silencing apparatus.
Background technique
The dividing plate of the general employing of the acoustic wave filter structure of existing band dividing plate and the complete contact type of inwall is namely selected the dividing plate that mates fully with the housing cross section for use, by dividing plate and housing interference fit, perhaps finishes the assembling of dividing plate and housing by the mode of resistance welding.
Because the whole periphery of dividing plate and housing contacts, even by interference fit or resistance welding mode, but because manufacturing factor or service wear, still have local location the slight gap of elongate can occur, meeting turbulization when high-speed gas passes through the gap by air-flow, and then produce ear-piercing howling, not only influence acoustic attenuation performance, and increased the source of noise.Therefore, be badly in need of a kind of diaphragm structure that can solve this problem of howling that slight gap produces between dividing plate and housing effectively on the market.
Summary of the invention
The present invention aims to provide a kind of silencing apparatus dividing plate and uses the silencing apparatus of this dividing plate, and the present invention produces ear-piercing howling in the time of can having avoided air by the slight gap between dividing plate and housing, has further reduced noise, has good acoustic attenuation performance.
Silencing apparatus dividing 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, the pore of giving vent to anger, air dispelling hole.
Described dividing plate is preferably circle, the also shape that can be designed to other according to silencing apparatus shape and the structure of correspondence, and not as square, rhombus etc.
When baffle design was circle, described boss was evenly distributed on the outer circumference of dividing plate.
A kind of silencing apparatus of the present invention comprises housing and dividing plate, and described silencing apparatus dividing plate outer is provided with at least three boss, and boss contacts with interference fit with inner walls, the dividing plate outer except boss part and housing between form the space.
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 the air outlet; At least one dividing plate is installed in the housing, and dividing plate is provided with air inlet pipe hole, the pore of giving vent to anger, air dispelling hole; Diffusing gas part after install as the silencing apparatus internal partition jointly in air dispelling hole on each piece dividing plate and space; Air inlet pipe hole on the dividing plate and suction port alignment, the pore of giving vent to anger on the dividing plate aligns with the air outlet; Suction tude is communicated with suction port after passing air inlet pipe hole on each piece dividing plate, and steam outlet pipe is communicated with the air outlet after passing the pore of giving vent to anger on each piece dividing plate.
The housing of described silencing apparatus is preferably cylindrical, and described dividing plate is preferably circle 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 of silencing apparatus is designed to cylindrically, when described dividing plate was designed to circle accordingly, described boss was evenly distributed on the outer circumference of dividing plate.
Key point of the present invention is to be arranged at the boss on the dividing plate outer, during assembling, dividing plate contacts with the interference fit of housing by boss structure, have only projection section closely to contact with housing on the dividing plate, form the space between all the other most of outers and cylindrical shell, the space of this part cooperates air dispelling hole to carry out design consideration as common diffusing air to open hole area, such design, the problem of the howling that slight gap produces between dividing plate and housing just can perfectly solve because also can not cause the reduction of erasure effect simultaneously because of extra space.
The part that boss of the present invention is connected with housing is not prone to the fine gap that produces howling, and reason is as follows:
1. boss and housing area of contact are few, easier applying.
2. boss and housing are interference fit, and centering property is good, the bearing capacity height, and load can withstand shocks;
3. shell body wall is thin, easily produces resiliently deformable, makes that the applying of boss and housing is tightr;
In sum, the present invention has solved because existing elongate gap to cause the problem of howling generation between dividing plate and the housing from design angle, thereby make the noise elimination better effects if, it is higher to make up-to-standard rate, quality of product is more stable, and silencing apparatus dividing plate provided by the invention is applicable to the silencing apparatus of all kinds of band dividing plates.
