Problems solved by technology
[0002] Motorcycles will discharge high-temperature exhaust gas from the exhaust pipe during use. Since the surface of the exhaust pipe is usually smooth, the contact time between the cold air and its outer wall is very short during driving, and the air flow rate is too fast and the air cooling effect is poor. Therefore, this The high-temperature exhaust gas will cause a large amount of heat to be emitted from the surface of the exhaust cylinder, causing the surface of the cylinder to be very hot
Because the installation position of the exhaust pipe is usually installed next to the pedal frame of the motorcycle, and passengers usually tilt the vehicle body when getting on and off the vehicle, this action makes the passenger's legs touch the exhaust pipe without paying attention, causing burns

The invention relates to the technical field of motorcycle accessories, in particular to an air exhaust cylinder for a motorcycle. The air exhaust cylinder comprises an air inlet channel, wherein oneend of the air inlet channel is connected with an air exhaust pipeline of the motorcycle, the other end of the air inlet channel is fixed to a threaded base, the other side of the threaded base is provided with an inner cylinder, and the inner cylinder communicates with the air inlet channel. The air exhaust cylinder is characterized in that the outer surface of the inner cylinder is provided withconnecting threads, and is furthermore provided with a plurality of annular cooling fins, the cooling fins are internally provided with internal threads matched with the connecting threads and are screwed on the inner cylinder, and an outer cover of the inner cylinder is sleeved with an outer sleeve. The air exhaust cylinder has the advantages that when the motorcycle is driven, airflow can enterair inlets through a horn mouth and then enter the outer sleeve, then the airflow in the outer sleeve can be discharged from a space left between an end cover and the tail end of the inner cylinder along airflow circulation holes, and then the purpose of cooling the outer sleeve and the inner cylinder is achieved.
