Description
Technical field
The present invention relates to a kind of motor vehicle component, just be meant the motor exhaust silencing apparatus concretely.
Background technique
Noise eliminator of motorcycle is important components very on the motorcycle, and it can reduce the content of the intact CH waste gas that causes of unburned the waste gas noise that comes out from engine emission and the waste gas.But the waste gas that is discharged in the silencing apparatus often contains the intact inflammable mixture of unburned, meeting air in the time of will causing the intact inflammable mixture of unburned in the motor like this in entering silencing apparatus rekindles and sends explosive sound, be commonly called as muffler explosion, it is the most common to blow out phenomenon with oil return on motorcycle.Therefore muffler explosion can cause engine operating temperature too high, and acceleration performance difference and travel has unablely influenced the life-span and the quality of motorcycle greatly.The way that solution motorcycle oil return is at present blown out is normally increasing ACV valve (velocity air recuperation valve or air cutoff valve) or TWC Three Way Catalytic is being set in silencing apparatus on the Carburetor, but can increase the manufacture cost of motorcycle like this, and on Carburetor, install the restriction that the ACV valve also can be subjected to assembly space additional.
Summary of the invention
At above problem, the problem to be solved in the present invention provides a kind of improved exhaust muffler for motorcycle, has had behind this silencing apparatus to install the ACV valve on the Carburetor additional or to set up TWC Three Way Catalytic and just can eliminate the oil return of motorcycle and blow out phenomenon in silencing apparatus.
For solving the problems of the technologies described above, exhaust muffler for motorcycle provided by the invention contains outlet pipe and silencing apparatus tube, and the front end of silencing apparatus tube is a conically shaped, and the silencing apparatus tube inner chamber is stretched into from conically shaped in the outlet pipe rear end; The rear end of outlet pipe is positioned at conically shaped, is provided with the dividing plate of band mesh in the rear end of conically shaped inner chamber, has additional one deck sound-absorbing material on the madial wall of conically shaped; The rear end of outlet pipe is provided with the stifle of band air-flow via hole, and is close at outlet pipe on the tube wall of rear end and is provided with radial hole uniformly.
This type of traditional silencing apparatus, its outlet pipe rear end enters into first anechoic room after passing the conically shaped inner chamber, and the outlet pipe rear port does not have any stopping, when the high-temp waste gas of motor with at a high speed when outlet pipe enters into first anechoic room, if contain in the waste gas without clean-burning inflammable mixture, then inflammable mixture is met the air flash fire at first anechoic room, blows out phenomenon thereby produce.
The present invention is withdrawn into the rear end of outlet pipe and is positioned at conically shaped, and the dividing plate of band mesh is set in the rear end of conically shaped inner chamber, thereby the conically shaped inner chamber is separated first chamber that enters silencing apparatus as waste gas.High temperature and high speed waste gas in the outlet pipe is under the stopping of outlet pipe rear port stifle, through air-flow via hole on the stifle and the radial hole on the exhaust wall, be divided into many threads and enter the conically shaped inner chamber, air-flow is expanded, flow velocity reduces, powerful microseismic noise is decayed, and the sound-absorbing material on the conically shaped madial wall not only absorbs sound, and air-flow is also played the energy-absorbing buffering effect.Contain inflammable mixture even enter in the waste gas of conically shaped inner chamber, but, also can not send explosive sound when in the conically shaped inner chamber, meeting air burning because flow velocity reduces greatly.Air-flow after flow velocity the reduces mesh on dividing plate again is dispersed and enters next chamber, flow velocity further reduces air-flow through reexpanding, this moment, the temperature of air-flow reduced greatly, was lower than the burning-point of inflammable mixture, thereby reached the purpose of eliminating muffler explosion.
The technique effect that the present invention obtains is: effectively eliminated the phenomenon that the motorcycle oil return is blown out, need not install the ACV valve on the Carburetor additional or set up TWC Three Way Catalytic in silencing apparatus after adopting this silencing apparatus, thereby reduced the manufacture cost of motorcycle.

Embodiment
The invention will be further described below in conjunction with drawings and Examples:
Referring to accompanying drawing, a kind of exhaust muffler for motorcycle, the front end of silencing apparatus tube 1 are conically shaped 2, and silencing apparatus tube 1 inner chamber is stretched into from conically shaped 2 in outlet pipe 3 rear ends, outlet pipe 3 and the welding of conically shaped 2 front ends.The rear end of outlet pipe 3 is positioned at conically shaped 2, is provided with the dividing plate 4 of band mesh 7 in the rear end of conically shaped 2 inner chambers, has additional one deck sound-absorbing material 5 on the madial wall of conically shaped 2.The rear end of outlet pipe 3 is provided with the stifle 6 of band air-flow via hole 8, and is close at outlet pipe 3 on the tube wall of rear end and is provided with radial hole 9 uniformly.
The dividing plate 4 of band mesh 7 separates first chamber that enters silencing apparatus as waste gas with conically shaped 2 inner chambers, and the rear end of outlet pipe 3 is withdrawn into and is positioned at conically shaped 2.The high temperature and high speed waste gas that outlet pipe is 3 li is under the stopping of stifle 6, radial hole 9 on air-flow via hole 8 on the stifle 6 and outlet pipe 3 walls, be divided into many threads and enter conically shaped 2 inner chambers, air-flow is expanded, flow velocity reduces, powerful microseismic noise is decayed, and the sound-absorbing material 5 on conically shaped 2 madial walls not only absorbs sound, and air-flow is also played the energy-absorbing buffering effect.Contain inflammable mixture even enter in the waste gas of conically shaped 2 inner chambers, but, also can not send explosive sound when in conically shaped 2 inner chambers, meeting air burning because flow velocity reduces greatly.Air-flow after flow velocity the reduces mesh on dividing plate 47 again is dispersed and enters next chamber, flow velocity further reduces air-flow through reexpanding, this moment, the temperature of air-flow reduced greatly, was lower than the burning-point of inflammable mixture, thereby had reached the purpose of eliminating muffler explosion.
From accompanying drawing, also can further find out: the inner conical-tube 10 that in conically shaped 2, is provided with a band mesh, sound-absorbing material 5 is installed between inner conical-tube 10 and the conically shaped 2, inner conical-tube 10 not only plays the effect of support fixation to sound-absorbing material 5, can also increase the roughness of sound-absorbing material wall, reduce gas flow rate.
The sidewall of dividing plate 4 is provided with Stainless Steel Cloth 11, and the hole on the Stainless Steel Cloth 11 is more fine and closely woven, and is more obvious to the reduction of speed effect of air-flow.And, Stainless Steel Cloth 11 has been arranged after, the mesh on the dividing plate 4 just can be De Taimi, to improve its intensity, has guaranteed its fixed support effect to Stainless Steel Cloth 11.
Explanation is at last, above embodiment is only unrestricted in order to technological scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technological scheme of the present invention, and not breaking away from the aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
