Abstract
The utility model relates to the technical field of motorcycle accessories, in particular to a muffler for a motorcycle. The muffler comprises a muffling housing, wherein the muffling housing comprises an inner housing, an outer housing and a fixing part for fixing the inner housing with the outer housing; a closed muffling interlayer is formed between the outer surface of the inner housing and the inner surface of the outer housing; a muffling material is packed in the muffling interlayer; the muffling housing is spiral; the inner surface of the inner housing consists of concave and convex surfaces which are connected. According to the utility model, air flow exhausted by the motorcycle enters the muffling housing, and the spiral design of the muffling housing lengthens the muffling channel, so that when the air flow passes through the spiral muffling housing, a certain muffling effect can be achieved; as the muffling material is arranged in the muffling interlayer, a further muffling effect can be achieved; the inner surface of the inner housing is designed into the concave and convex surfaces which are connected, and thus can perform a muffling function. Therefore, noise generated by the air flow can be greatly reduced.
Description
Technical field
The utility model relates to motorcycle accessories technical field, is specifically related to a kind of motorcycle silencer.
Background technique
The air-flow that motorcycle produced in when operation can send huge noise, therefore, needs silencing apparatus to eliminate air power noise, stops sound transmission and allows air-flow to pass through.But the effect that current silencing apparatus abates the noise is poor.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of motorcycle silencer simple in structure, reasonable in design, and its air-flow that can effectively discharge motorcycle carries out noise reduction, reduces noise pollution.
Realize the technical solution of the utility model as follows:
Motorcycle silencer, comprise sound attenuation, sound attenuation is made up of inner housing, frame and fixed block that inner housing, frame are fixed together, forms the noise reduction interlayer of sealing between inner housing outer surface, frame internal surface, in noise reduction interlayer, is filled with quieter material; Sound attenuation is helical, and the internal surface of described inner housing is concavo-convex connected arc shaped surface.
Described quieter material can be silencing cotton or fibre cloth or steel wire lump.
For the air-flow of further motorcycle being discharged carries out noise reduction, the enlarging that is taper by the end of described sound attenuation.
Adopt such scheme, the air-flow that motorcycle is discharged enters in sound attenuation, the helical design of sound attenuation, extend silencers channel, when air-flow is by spiral helicine sound attenuation like this, can there is certain sound deadening, quieter material is set in interlayer and can further realize noise reduction, also can play sound deadening and inner housing internal surface is designed to concavo-convex connected arc shaped surface, thereby greatly reduce the noise that air-flow produces.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Referring to Fig. 1, motorcycle silencer, comprise sound attenuation 1, sound attenuation is made up of inner housing 2, frame 3 and fixed block that inner housing, frame are fixed together, the noise reduction interlayer 4 that forms sealing between inner housing outer surface, frame internal surface is filled with quieter material in noise reduction interlayer; Sound attenuation is helical, and sound attenuation can also be arranged to curved shape in order to extend silencers channel certainly; The internal surface of inner housing is concavo-convex connected arc shaped surface 5.The end of sound attenuation is the enlarging 6 of taper.In concrete enforcement, quieter material can be silencing cotton or fibre cloth or steel wire lump.
Claims (3)
1. motorcycle silencer, comprise sound attenuation, it is characterized in that, sound attenuation is made up of inner housing, frame and fixed block that inner housing, frame are fixed together, the noise reduction interlayer that forms sealing between inner housing outer surface, frame internal surface is filled with quieter material in noise reduction interlayer; Sound attenuation is helical, and the internal surface of described inner housing is concavo-convex connected arc shaped surface.
2. motorcycle silencer according to claim 1, is characterized in that, described quieter material can be silencing cotton or fibre cloth or steel wire lump.
