Description

Technical Field

[0001] The utility model relates to the field of shift gears, in particular to a motorcycle shift gear which is convenient to maintain. Background Art

[0002] Motorcycle shift gear maintenance is essential to keep the motorcycle in normal operation and extend its service life. It usually involves regular cleaning, checking for wear, adding lubrication, avoiding overloading and overheating, and professional repairs. By performing these maintenance tasks regularly, you can ensure that the motorcycle's shift system remains smooth and reliable, thereby extending the overall service life of the motorcycle.

[0003] Existing motorcycle shift gears are usually set in an integrated manner when in use, so that after the motorcycle shift gears are installed on the output shaft and input shaft of the gearbox, the dirt layer generated by the output shaft and the input shaft during years of use will thicken the outer diameters of the output shaft and the input shaft, making it difficult to disassemble the shift gears from the output shaft and the input shaft for maintenance.

[0004] Therefore, in view of the fact that the dirt layer generated by the long-term use of the above-mentioned output shaft and input shaft will thicken the outer diameter of the output shaft and the input shaft, making it difficult to disassemble and maintain the shift gear from the output shaft and the input shaft, a motorcycle shift gear that is easy to maintain can be designed. The shift gear uses a split structure design, so that it does not need to be disassembled along the outer diameter of the gearbox output shaft and the input and output shaft, but can be disassembled through its own structural combination, which is convenient for solving the above-mentioned problem.
