The manual gearbox is mainly composed of gears and shafts, and the variable speed transformers are generated by different gear combinations. The automatic transmission is composed of four parts: shell, variable speed mechanism, electric control system and hydraulic control system. Through hydraulic transmission and gear combination To achieve variable speed torque.
It is divided into manual, automatic two, manual gearbox mainly composed of gear and shaft, through different gear combinations produce variable speed moment; and automatic transmission box AT is composed of hydraulic torque converter, planetary gear and hydraulic control system, Through the hydraulic transmission and gear combination to achieve the variable speed moment.
Third, the use of neutral, interruption of power transmission, so that the engine can start, idle, and easy to shift gears or carry out; Second, the direction of the engine in the same direction of rotation, the car can reverse the way; Power output.
