Abstract

The invention discloses a box type silencer of a motorcycle. Three partition plates are arranged in a box type housing to divide an inner cavity of the housing into four independent chambers, and the outlet end of an exhaust pipe communicates with the first chamber; a first throttling pipe is arranged in the second chamber, and the first throttling pipe communicates the first chamber and the second chamber; a throttling hole is formed in the second partition plate to communicate the second chamber and the third chamber; a second throttling pipe is arranged in the third chamber, and the second throttling pipe communicates the second chamber and the fourth chamber. A second box type housing is arranged on the side wall of the box type housing, and the inner cavity of the second box type housing is divided into a fifth chamber and the sixth chamber through a fourth partition plate; a throttling hole is formed in the fourth partition plate to communicate the fifth chamber and the sixth chamber; an exhaust port is formed in the housing wall of the six chamber; and the fourth chamber communicates with the fifth chamber through the third throttling pipe. The silencer disclosed by the invention can greatly reduce the exhaust noise.

Description

technical field [0001] The invention relates to the improvement of the structure of a motorcycle muffler, in particular to a box-type muffler for a motorcycle. The muffler can greatly reduce exhaust noise and belongs to the technical field of mufflers. Background technique [0002] Motorcycle muffler is a device that allows airflow to pass through to attenuate noise. The high-temperature exhaust gas emitted by motorcycle engine is directly discharged into the atmosphere after noise reduction and cooling through the muffler. It is one of the important parts on motorcycles. The performance of the muffler not only affects the noise of the motorcycle, but also has a great influence on the performance of the engine, such as power, fuel consumption, and torque. [0003] According to different noise reduction principles, motorcycle mufflers can be divided into the following three types: [0004] 1. Resistive muffler: This kind of muffler uses the sound absorption effect of sound-...
