The transmission system of SHACMAN mainly consists of the transmission assembly, differential and drive shaft.The transmission system comes in manual and automatic types. A manual transmission requires the driver to manually change gears by operating the clutch, while an automatic transmission can automatically adjust gears based on vehicle speed and engine speed to provide a smoother driving experience. The differential plays a crucial role in the transmission system, effectively addressing the speed difference between the left and right wheels due to turning, ensuring that the vehicle can complete the turning action smoothly and steadily. The drive shaft is responsible for transferring the power output from the transmission system to the differential and driving the wheels to rotate.
