Multi-loop type silencer on motorcycle

Abstract

The invention discloses a multi-loop type silencer on a motorcycle. The multi-loop type silencer comprises a tail gas exhaust pipe and a silencing pipe on the motorcycle. The tail gas exhaust pipe is inserted into the silencing pipe, the silencing pipe comprises a cylindrical main pipe body, a contracted pipe is formed at the right end of the main pipe body, and an external thread sleeve is formed at the tail end of the contracted pipe. An annular check ring is formed on the outer wall of the tail gas exhaust pipe, the check ring is sleeved with a locking sleeve in an inserted manner, the locking sleeve is screwed to the external thread sleeve, and the check ring is clamped between the locking sleeve and the external thread sleeve. According to the multi-loop type silencer, a plurality of partition plates are arranged in the silencer, the partition plates divide the silencer into multiple partition cavities, the partition cavities are communicated through ventilation pipes to form multiple exhaust loops, multiple silencer bodies are installed in the multiple exhaust loops, and therefore noise can be effectively attenuated.

Description

technical field [0001] The invention relates to the technical field of motorcycle mufflers, in particular to a multi-circuit muffler on motorcycles. 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. Existing motorcycle mufflers can be divided into three types: resistive mufflers, resistive mufflers and impedance composite mufflers. Resistive mufflers refer to the use of sound-absorbing materials or sound-absorbing structures to make the noise transmitted along the pipeline vary with distance. And attenuation, so as to achieve the purpose of noise reduction; the resistance muffler is to use the sudden expansion (or contraction) of the pipe section or bypass the resonant cavity, so that the sound waves of certain frequencies propagating along the pipe are reflected back to the direction of the sound source at the sudden change. So as to achieve the purpose...

AI Technical Summary

Problems solved by technology

The existing motorcycle resistance muffler is mainly to install a tubular muffler on the exhaust pipe, and the inner wall of the muffler is formed with a structure of sudden expansion (or contraction) to silence the sound, but the tail gas discharged from the exhaust pipe contains small Substances in the form of particles and dust, small particles and substances in the form of dust will adhere to the inner wall of the muffler, and the cleaning of the inner wall of the muffler is more troublesome
