Silencer of motorcycle cylinder

Abstract

The invention discloses a silencer of a motorcycle cylinder. The silencer comprises an air inlet pipe, wherein the air inlet pipe is connected with one end of a sound absorption and air inlet opening through threads; the other end of the sound absorption and air inlet opening penetrates through a shell and is fixedly connected with a sound absorption chamber; the left side of the sound absorption chamber is fixedly connected with one end of a sound absorption and air outlet opening; the other end of the sound absorption and air outlet opening is connected with an inner pipe through threads; the inner pipe penetrates through an outer pipe, and extends into the outer pipe; sound attenuation holes are formed in the inner pipe; the top and the bottom of the inner pipe are separately fixedly connected with a sucking disc; each sucking disc is fixedly connected with the inner wall of the outer pipe; the left side of the outer pipe is fixedly connected with one end of an air outlet; and the other end of the air outlet penetrates through the shell, and is connected with an air outlet pipe through threads. According to the silencer of the motorcycle cylinder, a double-sound-attenuation structure is adopted, so that a sound attenuation effect is more obvious; use by people is facilitated; and a driver is free from annoyance caused by noise.

Description

technical field [0001] The invention relates to the technical field of motorcycle accessories, in particular to a noise reduction device for a motorcycle cylinder. Background technique [0002] Motorcycle, driven by a gasoline engine, is a two-wheeled or three-wheeled vehicle whose front wheels are steered by the handlebars.

Problems solved by technology

Noise will not only cause hearing damage, but also induce a variety of cancer-causing and fatal diseases, and also interfere with people's life and work. During the work of internal parts of the cylinder, a lot of noise is often produced, which makes motorcycle users feel irritable. Most of the vehicle noise transmission medium is gas. The louder the noise, the worse it is for people. At present, most motorcycle cylinders on the market do not have mufflers. When driving, the noise is very loud, which makes the driver upset and affects the mood. accident
