Embodiment Construction

[0017] Such as figure 2 Shown, the motorcycle muffler of the present invention, it is installed in motorcycle exhaust pipe 1 air outlet, and described muffler comprises one chamber 2, two chambers 3 and three mufflers of three chambers 4, is three chambers between one chamber and two chambers There are partitions 5-1 and 5-2 respectively arranged between each anechoic chamber, the partitions are respectively provided with holes welded to connect the ventilation pipes of each anechoic chamber, the air inlet end of one chamber and the air outlet of the exhaust pipe Connection, the length of the first chamber accounts for 1 / 3-1 / 2 of the total length of the muffler, the ventilation pipe 6-1 between the first chamber and the second chamber passes through the third chamber and is fixed between the first chamber and the third chamber and the second chamber and the third chamber The vent pipe 6-2 between the second chamber and the third chamber is fixed on the partition between the s...

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. Such as figure 1 As shown, the general motorcycle muffler is a system of 2 to 4 chambers. The air flow sequentially passes through the ventilation pipes on the partitions between the chambers to discharge the muffler. Reflection reduces muffler vibration and noise. 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 structure and good noise reduction effect. [0004] In order to solve the above problems, th...
