Abstract
The utility model provides a motorcycle exhaust air silencer, which comprises a pipe. An air inlet pipe and an air outlet pipe are respectively arranged at two ends of the pipe. Air flow is exhausted from an engine, enters the silencer air inlet pipe from an air exhaust pipe, enters a first cavity from an inner pipe to start expand and contract, and expands again to enter a second cavity, enters a third cavity after contraction and resonance functions, then enters a fourth cavity through resonance function of a hole punching plate, sequentially passes the fourth cavity, a sixth cavity and a fifth cavity through contraction function of a flat pipe, and finally is exhausted to the atmosphere from the fifth cavity through the air outlet pipe. The fifth cavity, the sixth cavity and a seventh cavity enable the air flow to continuously expand and contract to perform a silencing function. Exhausted fume is exhausted from the air outlet pipe through a plurality of times of expansion, contraction and resonance functions, and noise can be effectively dissipated in the process of a plurality of times of expansion and contraction.
