Description
Technical field
The utility model belongs to the silencer for gas flow technical field used in conjunction with sound-absorbing material.
Background technique
The main structure of existing noise eliminator of motorcycle comprises suction tude, suppressor case, hush tube and sound absorbing material, hush tube to be built in suppressor case and to be connected with suction tude, outside hush tube, in suppressor case, be provided with bearing reticular tube, between bearing reticular tube and suppressor case, fill sound absorbing material.
In prior art, noise eliminator of motorcycle mainly adopts straight-tube structure, namely hush tube and suppressor case are straight tube, its noise-cancelling theory belongs to dissipative muffler, utilize the sound absorption of muffler material or sound absorption structure, the noise of air-flow is propagated in muffler material, dissipates because acoustic energy is converted into heat energy by friction, makes to decay along the noise propagated in suppressor case with distance.Its shortcoming is: 1. this kind of dissipative muffler has good soundproof effect to high frequency noise, and centering low frequency noise is poor to low frequency soundproof effect.2. the usual crooked radian of suction tude is less, and waste gas is by very large noise occurring during suction tude, and in addition, suction tude is generally mono-layer tube, and high temperature, high pressure exhaust gas can make suction tude body temperature raise fast, affect the heat dispersion of motorcycle.
Model utility content
The utility model is intended to provide one to eliminate the noise by centering low frequency noise, and can carry out the exhaust system for motorcycle silencing apparatus of heat insulation and heat control to suction tude.
The purpose of this utility model can be reached by following measures: exhaust system for motorcycle silencing apparatus, comprise the suppressor case of taper, the hush tube that this housing is built-in and with the suction tude outside housing, described suppressor case inner chamber is provided with support tube with holes, is filled with muffler material between support tube and suppressor case; Suppressor case inlet end is equipped with cylindric connecting tube, and the suction port of connecting tube is connected with suction tude, and the air outlet of connecting tube is connected with hush tube, and this connecting tube forms cone cylinder at the position near air outlet, and the perisporium of hush tube has pore; The double-deck tracheae that described suction tude is made up of external pipe and inner tube, leaves thermal-protective coating between external pipe and inner tube.
Technique scheme difference with the prior art is: arrange connecting tube at the inlet end of suppressor case, connect suction tude to hush tube, waste gas along with noise enters in hush tube by suction tude, due to the centrum shape that connecting tube diminishes gradually at the position Formation cross-section near air outlet, noise is because the unexpected change of pipeline section, cause impedance phenomenon, sound wave produce reflection or interference phenomenon, thus reduce, mid-frequency noise; The waste gas sprayed from the pore of hush tube enters in suppressor case, and the adjoint high frequency noise of waste gas is absorbed by muffler material, and such structure absorbs the noise of different frequency serially; In addition, adopt the suction tude that double-deck tracheae is made, the air heat-insulation layer between inner tube and external pipe can carry out heat insulation and heat control to high-temp waste gas.The utility model can have stronger attenuation to the noise of different frequency, good muffling effect.
Further, described suction tude at least arranges a curved part, and the camber of curved part is less than or equal to 90 °, and waste gas, through the curved part of suction tude, can reduce the striking velocity of waste gas, also utilizes the principle of acoustic reflection to reduce noise in addition.
Further, the cross section of described suppressor case is polygonal, can increase the surface of contact of noise and sound absorbing material, strengthens noise alleviation effect.
