[0002] The transmission, also known as the gearbox, is a mechanism used to change the speed and torque from the engine. It can change the output shaft and input shaft transmission ratio in a fixed or divided manner. The transmission is composed of a speed transmission mechanism and a control mechanism. Some cars also have a power output mechanism. Most transmission mechanisms use ordinary gear transmissions, and some use planetary gear transmissions. Ordinary gear transmission speed change mechanisms generally use sliding gears and synchronizers, etc.

[0003] Existing transmissions are difficult to install and disassemble. The input end of the transmission is usually connected to the engine output shaft, generally using a key connection. However, this connection method is not stable enough and can easily lead to a gap between the input end of the transmission and the engine output shaft, which can easily lead to breakage over time.
