Abstract
The invention provides a noise eliminator of a motorcycle. The front end of a noise eliminator drum (1) is provided with a cone-shape drum (2); the pipe wall near the rear end of an exhaust pipe (3) is provided with small radial holes (7), the rear end of the exhaust pipe (3) passes extends into the cone-shape drum (2) and then extends to be connected with a first partition plate (5) inside the noise eliminator drum (1), and the first partition plate (5) is provided with air flow via holes (6) communicated with the exhaust pipe (3); and an inner cavity of the cone-shape drum (2) is connected with space at the front of the first partition plate (5) inside the noise eliminator drum (1) into an integer so as to form a first noise elimination cavity of the noise eliminator. The invention enhances the low-speed property of an engine of the motorcycle assembled with the noise eliminator without influencing the original noise elimination effect of the motorcycle assembled with the noise eliminator and reduces the manufacturing cost.
Description
Technical field
The present invention relates to a kind of silencing apparatus, be meant noise eliminator of motorcycle concretely.
Background technique
On the motorcycle of existing equipped 110 h type engine hs, its common acoustic wave filter structure as shown in Figure 1, the front end of silencing apparatus tube 1 is a conically shaped 2, be close to rearward end in the conically shaped 2 and be provided with bracing ring 8, the rear end of engine exhaust pipe 3 continues across bracing ring 8 and welding after putting in conically shaped 2, space in this bracing ring 8 and the silencing apparatus tube 1 between first dividing plate 5 is first noise elimination cavity of silencing apparatus, the rear end of outlet pipe 3 is positioned at fore-and-aft direction position placed in the middle substantially in this first noise elimination cavity after passing bracing ring 8, outlet pipe 3 rear ends are provided with the stifle 4 of band air-flow via hole 6, and the tube wall that outlet pipe 3 is close to stifle 4 is provided with radial hole 7.Though the silencing apparatus of this structural type in use has comparatively desirable noise elimination effect at present, the low-speed performance of motor is poor, and obviously the sensation acceleration is unable behind the engine start.
Summary of the invention
The problem to be solved in the present invention provides a kind of noise eliminator of motorcycle that can obviously improve the low engine speed performance under the prerequisite that does not influence the noise elimination effect.
For solving the problems of the technologies described above, noise eliminator of motorcycle provided by the invention, comprise outlet pipe and silencing apparatus tube, the front end of silencing apparatus tube is a conically shaped, the tube wall that is close to the rear end on the outlet pipe is provided with radial hole, the rear end of outlet pipe puts in first dividing plate that extends to behind the conically shaped with in the silencing apparatus tube and is connected, and first dividing plate is provided with the air-flow via hole that communicates with outlet pipe.
The present invention is prolonged the part that outlet pipe is positioned at the silencing apparatus tube, the length of whole engine exhaust pipe is extended, but do not change length and shape, promptly do not change the layout of outlet pipe on motor and vehicle frame from the motor end to this section of silencing apparatus engine exhaust pipe.Under the constant prerequisite of the internal diameter of outlet pipe, outlet pipe is long more, the interior air-flow of outlet pipe is just big more to the suction that produces in the firing chamber in the exhaust stroke, exhaust is cleaner, air inlet is also just more abundant, can also save the inertial force of piston in the exhaust stroke, this effect is obvious when engine speed is low, so can improve the low-speed performance of motor.
The space in first dividing plate the place ahead is linked as integral body in above-mentioned conically shaped inner chamber and the silencing apparatus tube, constitutes first noise elimination cavity of silencing apparatus, just cancels the bracing ring in original conically shaped, can reduce cost.Outlet pipe is supported between first dividing plate in conically shaped front end and the silencing apparatus tube, and the volume of first noise elimination cavity has increased, and has improved the elementary noise reduction reduction of speed effect of air-flow.
The technique effect that the present invention obtains is: improved the low-speed performance of the motorcycle engine that is fitted with this silencing apparatus, and do not influenced its original noise elimination effect, also reduced manufacture cost.
Description of drawings
Fig. 1 is the structural representation of noise eliminator of motorcycle described in the background technique;
Fig. 2 is a structural representation of the present invention;
Among the figure: 1. silencing apparatus tube; 2. conically shaped; 3. outlet pipe; 4. stifle; 5. first dividing plate; 6. air-flow via hole; 7. radial hole; 8. bracing ring.
Embodiment
The invention will be further described below in conjunction with drawings and Examples:
Referring to accompanying drawing 2, a kind of noise eliminator of motorcycle, the front end of silencing apparatus tube 1 is a conically shaped 2, the tube wall that is close to the rear end on the outlet pipe 3 is provided with radial hole 7, the rear end of outlet pipe 3 puts in first dividing plate 5 that extends to behind the conically shaped 2 with in the silencing apparatus tube 1 and is connected, and first dividing plate 5 is provided with the air-flow via hole 6 that communicates with outlet pipe 3.
The present invention only increases the length that outlet pipe 3 is positioned at silencing apparatus tube 1 place part, and length and shape invariance from the motor end to this section of silencing apparatus outlet pipe promptly do not change the layout of outlet pipe on motor and vehicle frame.The length of whole engine exhaust pipe is extended.Under the constant prerequisite of the internal diameter of outlet pipe, outlet pipe is long more, the interior air-flow of outlet pipe is just big more to the suction that produces in the firing chamber in the exhaust stroke, exhaust is cleaner, air inlet is also just more abundant, can also save the inertial force of piston in the exhaust stroke, this effect is obvious when engine speed is low, so improved the low-speed performance of motor.
As can be seen from Figure 2: the space in first dividing plate, 5 the place aheads is linked as integral body in conically shaped 2 inner chambers and the silencing apparatus tube 1, constitutes first noise elimination cavity of silencing apparatus.Just cancel the bracing ring in original conically shaped, can reduce cost like this.Outlet pipe 3 is supported between first dividing plate 5 in conically shaped 2 front ends and the silencing apparatus tube 1, and the volume of first noise elimination cavity has increased, and has improved the elementary noise reduction reduction of speed effect of air-flow.
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.
