Abstract

The invention discloses an exhaust resonant silencer and a motorcycle with the same. The exhaust resonant silencer comprises a silencer barrel and an internal tube assembly arranged in the silencer barrel for introducing and exhausting waste gas; the internal tube assembly includes a front tube, a middle tube and a tail tube, the tail tube is communicated with the middle tube for introducing waste gas into the tail tube, part of the tail tube is sleeved with a sleeve, a first resonant cavity is formed between the sleeve and the tail tube, and the sidewall of the tail tube corresponding to the sleeve is provided with a radial resonant hole whereby an inner cavity of the tail tube is communicated with the first resonant cavity; the resonant cavity is arranged in the silencer, so that loudness and sharpness of high-frequency noise can be decreased; the tone is greatly improved; through simple adjustments on internal structure of the silencer, the cost of the silencer can be effectively reduced without decreasing the silencing performance of the silencer or affecting dynamic performance of an engine.

Description

technical field [0001] The invention relates to the field of noise reduction, in particular to an exhaust resonance type muffler and a motorcycle thereof. Background technique [0002] At present, in order to obtain better exhaust sound quality, the motorcycle industry generally needs to use sound-absorbing materials in the muffler. After using sound-absorbing materials, due to technical reasons, the muffler must be made of stainless steel (if ordinary steel is used, it must be "painted inside" to prevent rust on the inner surface of the muffler. At this time, "painted inside" will cause failure of sound-absorbing materials). The "sound-absorbing material + stainless steel" muffler is expensive and has poor economic benefits, which is not conducive to cost control, and the processing process is complicated and the production efficiency is low. [0003] Therefore, in order to solve the above problems, there is a need for an exhaust resonance type muffler and its motorcycle,...
