Silencer and motorcycle with same

Abstract

The invention discloses a silencer and a motorcycle with the silencer. The silencer comprises a shell, an air inlet pipe, an air outlet pipe and a plurality of speed reducing devices, wherein a frontcover is arranged at the front end of the shell, a rear cover is arranged at the rear end of the shell, a baffle is arranged in an inner cavity of the shell, the inner cavity of the shell is divided into a front cavity and a rear cavity by the baffle, and the front cavity and the rear cavity communicate with each other through a plurality of vent holes located in the baffle; the air inlet pipe isarranged on the front cover, and the outside part communicates with the front cavity through the air inlet pipe; the air outlet pipe is arranged on the rear cover, and the outside part communicates with the rear cavity through the air outlet pipe; and the speed reducing devices are arranged on one side of the baffle, the speed reducing devices are located in the rear cavity, and the speed reducingdevices communicate with the corresponding vent holes in the baffle. Due to the adoption of the above structure, when the tail gas of the motorcycle flows in the speed reducing devices, all components in the speed reducing devices are used for blocking the tail gas, so that the flow velocity of the gas flow is reduced, and the noise which is generated in the emission process of the tail gas is further reduced.

Description

technical field [0001] The invention relates to a muffler and a motorcycle with the muffler. Background technique [0002] The muffler refers to the airflow pipeline with noise transmission at the same time, the noise reduction device can be used to attenuate the noise in the pipeline by using the pipeline and the elbow with the sound-absorbing lining or the pipeline with a sudden change in the cross-sectional area and other pipelines with discontinuous acoustic impedance. or reflect back. The former is called a resistive muffler, the latter is called a resistive muffler, and there are also impedance compound mufflers. [0003] Motorcycles are one of the important means of transportation, and their noise pollution seriously affects the quality of life of urban residents. Existing motorcycles, especially high-power motorcycles, will make harsh noises when they are gasping. , in order to further improve the current situation that the existing motorcycle muffler has a bad noi...

[0003] Motorcycles are one of the important means of transportation, and their noise pollution seriously affects the quality of life of urban residents. Existing motorcycles, especially high-power motorcycles, will make harsh noises when they are gasping. , in order to further improve the current situation that the existing motorcycle muffler has a poor sound attenuation effect, the structure of the existing motorcycle muffler is further improved
