The role of the gearbox

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

The basic working principle of automobile gearboxes: manual gearboxes are mainly composed of gears and shafts, and speed and torque are generated through different gear combinations, while automatic gearboxes AT are composed of hydraulic torque converters and planetary gears. It is composed of a hydraulic control system and achieves variable speed and torque through hydraulic transmission and gear combination.
