Embodiment Construction

[0017] As shown in Figure 2, the motorcycle muffler of the present invention is installed on the outlet of the motorcycle exhaust pipe 1, and the muffler includes three mufflers of a cavity 2, two cavities 3 and three cavities 4, one cavity and two cavities There are three cavities between each anechoic cavity, and partitions 5-1 and 5-2 are respectively arranged between each anechoic cavity, and the holes for welding and connecting the ventilation pipes of each anechoic cavity are respectively arranged on the partitions, and the intake end and the exhaust pipe of one cavity The length of the first chamber accounts for 1 / 3-1 / 2 of the total length of the muffler, and the ventilation pipe 6-1 between the first chamber and the second chamber passes through the third chamber and is fixed on the first chamber and the third chamber and the second chamber and the second chamber. On the dividing plate between the three chambers, the ventilation pipe 6-2 between the second chamber and t...

Abstract

The motorcycle silencer installed at the gas exhaust port of motorcycle includes three silencing cavities, the first one, the second one and the third one between the first one and the second one, and partition plates between each two silencing cavities. The partition plate between the second cavity and the third cavity is provided with ventilation holes, the first cavity has its air inlet connected to the exhaust pipe and a length of 1 / 3-1 / 2 total length of the silencer, the first cavity and the second cavity are connected via ventilation pipe through the third cavity, and the third cavity is provided with ventilation pipe through the second cavity and stretched beyond the silencer. Compared with available technology, the motorcycle silencer of the present invention has great amount of spoil, full chemical reaction of waste gas, increased gas flow area, less vibration, less exhaust and low noise.

Description

technical field [0001] The invention relates to a motorcycle muffler. Background technique [0002] The motorcycle muffler is installed at the outlet of the exhaust pipe to eliminate the noise of the engine. The working principle of the silencer is to reduce the low frequency through resonance and reflection, and the result of this reduction is to reduce vibration and noise. As shown in Figure 1, the general motorcycle muffler is a system of 2 to 4 chambers. The airflow passes through the ventilation pipes on the partitions between the chambers to discharge the muffler, and the flow velocity is gradually reduced by the turbulence of the partitions. The resonance and reflection reduce the vibration and noise of the muffler. But its noise reduction effect is not ideal. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the existing motorcycle muffler and provide a motorcycle muffler with novel struc...
