Function of gearbox

Transmission is a mechanical device used to change the engine speed and torque. It can change the transmission ratio of the output shaft and the input shaft by fixing or stepping, which is also called gearbox. Transmission is composed of variable speed transmission mechanism and control mechanism, and some cars also have power output mechanism. Most of the transmission mechanisms are ordinary gear transmission, and some are planetary gear transmission. The transmission mechanism of ordinary gear transmission generally adopts sliding gear and synchronizer.

Basic working principle of automobile gearbox: Manual gearbox is mainly composed of gears and shafts, which can generate speed change and torque change through different gear combinations, while automatic gearbox AT is composed of hydraulic torque converter, planetary gear and hydraulic control system, which can realize speed change and torque change through hydraulic transmission and gear combination.
