Description

A kind of muffler shockproof for engine with supercharger noise reduction
Technical field
The utility model is related to auto parts and components field, and in particular to a kind of noise reduction shockproof for engine with supercharger noise reduction Device.
Background technology
Automotive engineering is growing, and the automobile with turbocharging technology is increasingly popularized, to the demand of booster also progressively Increase.And with the use of engine with supercharger, can produce such as booster deflation sound (when unclamp throttle when, closed throttle and Still in work, booster drastically increases booster to the pressure between air throttle, in order to ensure that driving needs the pressure high pressure Removal, and deflation sound is just generated along with the release of gases at high pressure, particularly in anxious accelerator releasing operating mode), booster utters long and high-pitched sounds, increases The bad noise such as depressor surge, influences client's subjective feeling.
It is in booster import and export plus muffler, number of patent application to have a kind of method for improving booster deflation sound problem Utility model patent for 201520414040.0 discloses a kind of discouraged noise silencing means of automobile turbo engine, and it is main Including sound gobo, sealed joint pipe, sealed joint pipe one end is provided with noise import, and the other end is provided with noise outlet, and sealing connects Adapter is embedded to be cased with two relative sound gobos, and sound gobo is provided with several holes, and sound gobo outside sets resonator Wall, resonance cavity wall surrounds several resonance chambers with sealed joint pipe.This " porous are cellular " structure and plus multiple Resonance chamber of the same size, through simulation analysis, can partially remove the discouraged noise of turbocharger and noise of uttering long and high-pitched sounds, but not Reach good shockproof effect.
Utility model content
It is the problem for overcoming the discouraged noise of automobile engine, especially turbocharged engine in the prior art larger, The utility model provide a kind of simple structure, it is reasonable in design can the shockproof muffler of noise reduction.
The utility model is achieved through the following technical solutions:A kind of muffler shockproof for engine with supercharger noise reduction, bag Include housing and be arranged on the central tube of enclosure interior, the tube wall periphery of the central tube is provided with center pipe axle to interval setting For forming 3 hollow shelfs of ring resonator, the tube wall of central tube is provided with noise reduction corresponding with each ring resonator Rectangular opening, the housing exterior walls are also enclosed with layer of silica gel.By the way that central tube to be designed to the structure of square hole hollow out, to greatest extent Hollow out is carried out to central tube and forms noise reduction rectangular opening, be correspondingly arranged with ring resonator, play a part of diffusing air current and buffering, Noise reduction can effectively be carried out, at the same housing exterior walls wrap up layer of silica gel, can not only protect muffler, may also operate as it is shockproof with And the further effect of noise reduction.
Preferably, the noise reduction rectangular opening is provided with 3 groups, and every group symmetrical to be provided with 2, and 3 groups of noise reduction rectangular openings are divided into macropore Group, mesopore group, aperture group, are corresponding in turn to from the top of central tube to end and are set with ring resonator.It is different big by setting The small noise reduction rectangular opening being arranged in order, can one by one carry out the absorption of different-waveband, be conducive to sound-deadening and noise-reducing.
Preferably, the housing includes upper shell, lower house, and the outer surface of the upper shell is provided with convex tendon, and end is provided with Screw connection structure, the inner surface bottom of the upper shell is additionally provided with coupling recess portion, and the lower house is syphon shape, and lower casing is external Surface is provided with venthole, and the end of lower house is provided with insertion piece attachment structure, can be fixed with rubber after insertion.Design insertion Piece, ensures the steadiness of its connection by only need to being simply inserted into and fix, greatly improved on the basis of its using effect is ensured The convenient degree that its assembling is used.
Preferably, the hollow shelf at the top of the central tube is provided with connection protuberance, in the connection protuberance and upper shell The coupling recess portion precision-fit of surface bottom portion.Design connection protuberance and the precision-fit of coupling recess portion, can improve connection accurate Property.
Preferably, upper shell is formed basepipe seal in upper shell by Vibration welding with lower house with lower house Cavity in.This connected mode has the advantages that air-tightness is good, burst pressure intensity is high and welding interval is short.
Compared with prior art, the utility model has the advantages that:By in enclosure interior and hull outside Design sound attenuation features, reach the effect of dual noise reduction, wherein, central tube is designed to the structure of square hole hollow out, by setting not The noise reduction rectangular opening being arranged in order with size is correspondingly arranged with ring resonator, plays a part of diffusing air current and buffers, and by A pair of different-wavebands are absorbed, sound-deadening and noise-reducing.Layer of silica gel is wrapped up in housing exterior walls simultaneously, muffler can be not only protected, also Shockproof and further noise reduction can be played a part of.
