Abstract

The invention discloses a novel silencer which comprises a barrel. The barrel is provided with an air inlet end and an air outlet end in an axial direction. A first partition plate and a second partition plate are arranged in a spaced manner in the barrel. The first partition plate and the second partition plate divide an inner cavity of the barrel into an expanded silencing cavity, a resonant silencing cavity and a third silencing cavity along an air flow flowing direction. A plurality of first through holes are formed in the first partition plate, and a plurality of third through holes are formed in the third partition plate. A front row bend pipe is arranged at the air inlet end of the barrel, an exhausting pipe is arranged at the air outlet end of the front row bend pipe, the exhausting pipe stretches into the expanded silencing cavity, the diameter of the exhausting pipe is smaller than the inner diameter of the expanded silencing cavity, and a plurality of ventilating holes are formed in the side wall of the exhausting pipe; a tail pipe is arranged at the exhausting end of the barrel, and an air outlet pipe communicating to the third silencing cavity is arranged in the tail pipe. By arranging the first and second partition plates in the barrel, high-temperature exhaust gas of the barrel changes suddenly for many times and sound energy is attenuated greatly, so that a roleof reducing exhausting noise is played.

Description

technical field [0001] The invention relates to the technical field of motorcycle accessories, in particular to a novel muffler. Background technique [0002] A motorcycle muffler is a device that allows airflow to pass through and attenuates noise, and is one of the important parts on a motorcycle. The performance of the muffler not only affects the noise of the motorcycle and the comfort of riding the motorcycle, but also has a great influence on the performance of the engine, such as power, fuel consumption, and torque. [0003] Existing mufflers have large jitter, high exhaust sound level and noise, poor overall performance, and cannot better eliminate large-scale and multi-frequency noise, so the scope of application is narrow. Contents of the invention [0004] The present invention aims to solve one of the above-mentioned technical problems in the related art at least to a certain extent. For this reason, the present invention provides a new type of muffler, the m...
