Detailed Implementation

[0014] Referring to the attached drawings, a motorcycle muffler includes a rear section (1) of the muffler, a front section (16) of the muffler, a first core tube (2), a second core tube (4), an air intake pipe (6), a first partition (3), a second partition (5), a first tailpipe (9), a second tailpipe (8), a third tailpipe (7), a tailpipe plug (10), a rear part of the anti-scalding plate (11), a middle part of the anti-scalding plate (13), a front part of the anti-scalding plate (14), a first hanging ear (12), and a second hanging ear (15). Its features are: the intake pipe (6) is welded to the front end of the rear section (1) of the muffler and connected to the front section (16) of the muffler by a clamp; the first baffle (3) and the second baffle (5) are both welded to the rear section (1) of the muffler; the core tube (7) is welded to the first baffle (3) and the second baffle (5); the first core tube (2) is welded to the first baffle (3); the third tail pipe (7) and the second tail pipe (8) are welded to the first baffle (3) and the rear section (1) of the muffler; the first tail pipe (9) is welded to the rear section (1) of the muffler; the end of the first tail pipe (9) is welded with a threaded sleeve (30); and the tail pipe plug is... (10) The first tailpipe (9) is fixed by the welded threaded sleeve (30). The rear part (11), the middle part (13), and the front part (14) of the anti-scalding plate are all fixed to the rear section (1) of the muffler by threaded connection. The rear section (1) of the muffler is fixed to the frame by the first hanging ear (12) and the second hanging ear (15) by threaded connection. The front section (16) of the muffler is fixed to the engine by the three flanges of the front section by threaded connection. Finally, the fixed front section (16) of the muffler and the rear section (1) of the muffler are connected as one unit by clamp connection.

[0015] With the tailpipe plug (10) still in place, the gas generated by the engine flows through the front section (16) of the muffler and the intake pipe (6) into the first chamber (31) of the rear section (1) of the muffler, then through the second core tube (4) into the second chamber (32). The gas in the second chamber (32) then enters the third chamber (33) through the first core tube (2), and finally, the gas in the third chamber (33) enters the atmosphere through the third tailpipe (7) and the second tailpipe (8). The rear section (1) of the muffler is divided into three chambers by the first partition (3) and the second partition (5), and then connected to the first core tube (2) by the second core tube (4), which increases the length of the gas flow path in the muffler. This design allows the muffler to achieve better sound wave effect and noise reduction effect in a limited space.

[0016] The rear section (1) of the muffler is bent at a certain angle at the end of the third tailpipe (7) and the second tailpipe (8). This design causes the gas discharged from the muffler to change direction at a certain angle, so that the hot airflow will not blow directly onto the rear seat armrest, taillight and the side box to be installed at the rear, thus improving the safety of the rear passengers and the added parts.

[0017] All three tailpipes can discharge exhaust gas normally. The end of the first tailpipe (9) is welded with a threaded sleeve (30) and a tailpipe plug (10) can be installed. When the tailpipe plug (10) is removed, the flow path of the exhaust gas of the muffler can be changed, so that some of the gas in the first chamber (31) no longer passes through the second chamber (32) but is directly discharged into the atmosphere through the first tailpipe (9) of the third chamber (33), which changes the motorcycle's power and sound.

[0018] The motorcycle muffler has a simple structure, and its tailpipe plug (10) can be disassembled and installed at will. The same motorcycle can be used in different environments with different muffler states, which greatly meets the user requirements and expands the usage environment of the motorcycle.

[0019] The specific embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
