The main functions are: to change the driving force and driving speed of the vehicle (shifting) under the condition of constant engine speed and torque; to enable the vehicle to travel in reverse (reversing); and to stop the engine without shutting down (neutral). According to the transmission form, the gearbox can be divided into three types: double-shaft type, three-shaft type, and combination type. The double-shaft type has two main shafts (excluding the reverse shaft) and is reduced by only one pair of gears. The three-shaft type has three main shafts (first shaft, intermediate shaft, second shaft) and is reduced by two pairs of gears. The combination type is composed of two gearboxes in series or parallel, so that more gears can be obtained with fewer gears.
