Function

The high efficiency gearbox mainly refers to the gearbox of the automobile, which is divided into manual and automatic two kinds. The manual transmission is made up of gears and shafts, resulting in variable speed torque through different gear combinations. The automatic transmission is composed of hydraulic torque converter, planetary gear, hydraulic variable pitch system and hydraulic control system. The change torque is achieved by the combination of fluid and gear.
Function: 1. Change the transmission ratio; 2. In the same direction of rotation of the engine, the car can be driven backward; 3. Use the gap, interrupt power transmission to enable the engine to start up, idle speed, and facilitate transmission change or power output.
