Which is more complicated, the graduation design of transmission or reducer?

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 common gear transmission mechanism generally adopts sliding gear and synchronizer.

The automobile reducer increases the torque from the transmission or universal transmission, reduces the rotation speed and changes the transmission direction of the torque; Differential is a mechanism that can make the left and right (or front and rear) driving wheels rotate at different speeds.
