The Principle Introduction of Gearbox

Manual gearbox is mainly composed of gears and shafts, through different gear combinations to produce variable speed torque; The automatic gearbox is composed of hydraulic torque converter, planetary gear and hydraulic control system, through the hydraulic transmission and gear combination to achieve variable speed torque.

Manual gearbox hydraulic torque converter is the most characteristic components, it consists of pump wheel, turbine and guide wheel and other components, direct input engine power transmission torque and clutch. Pump wheels and turbines are a pair of work sets, they are like the relative placement of the two fans, an active fan blowing wind will drive another passive fan blade rotation, the flow of air - the wind has become a kinetic energy transmission medium.

If the liquid instead of air as a kinetic energy transfer medium, the pump wheel will be driven by the liquid turbine rotation, and then between the pump wheel and turbine wheel improve the transmission efficiency of the liquid.
