Introduction to the gearbox principle

The manual gearbox is mainly composed of gears and shafts. The variable gear torque is generated by different gear combinations. The automatic gearbox is composed of hydraulic torque converter, planetary gears and hydraulic control system. The shifting torque is realized by hydraulic transmission and gear combination.

The manual gearbox hydraulic torque converter is the most distinctive component. It consists of pump wheels, turbines and guide wheels. It directly inputs the engine power transmission torque and clutch. The pump wheel and turbine are a pair of work stations that are positioned like the two fans. The active fan blower drives another passive fan blade to rotate, and the airflow-wind has become a kinetic energy transfer medium.

If the liquid replaces the air as a kinetic energy conversion medium, the pump wheel will be rotationally driven by the liquid turbine and then increase the efficiency of liquid transfer between the pump wheel and the turbine.
