Technical Field
[0001] The utility model relates to the technical field of mufflers, in particular to a motorcycle muffler fixing structure. Background Art
[0002] In terms of the existing fixed structure of motorcycle mufflers, motorcycle mufflers are usually connected to the frame using a single suspension method. The muffler structure consists of a lifting lug, an exhaust pipe, and a muffler barrel, with the lifting lug connecting to the frame. The lifting lug is usually welded to the muffler barrel near the exhaust pipe.
[0003] After the muffler is assembled, it forms a suspended connection with the lifting ear as the fulcrum. The root of the lifting ear is a section that is easy to break. The vibration during the driving of the motorcycle can easily cause metal fatigue of the muffler and defects in the welding point between the lifting ear and the muffler barrel, etc., resulting in fracture of the root of the lifting ear, thereby requiring the overall replacement of the muffler. On the one hand, it is easy to cause danger during driving, and on the other hand, it also increases costs.
