(1) Change the transmission ratio, expand the range of variation of the drive wheel torque and speed to adapt to the constantly changing driving conditions, and at the same time make the engine work under favorable conditions of high power and low fuel consumption;
(2) The vehicle can be driven backwards without changing the direction of rotation of the engine;
(3) Using the neutral gear, interrupting the power transmission, the engine can be started, shifted, and the transmission is shifted or the power output is facilitated.
(4) The transmission is composed of a shifting transmission mechanism and an operating mechanism, and a power take-off can be added when necessary. There are two ways to classify: according to the change of the transmission ratio and the difference of the manipulation mode.
