[0002] The gearbox is a gearbox that changes the transmission ratio and the direction of movement. It is located between the clutch and the central transmission. Its main function is to change the driving force and driving speed of the vehicle under the condition that the engine speed and torque remain unchanged, so that the vehicle can travel backwards and the engine can be stopped without being turned off. According to the transmission type, the gearbox can be divided into three types: double-axis type, three-axis type, and combination type. The double-axis type has two main shafts and is reduced by only one pair of gears. The three-axis type has three main shafts and is reduced by two pairs of gears. The combination type is composed of two gearboxes in series or in parallel, so as to obtain more gears with fewer gears. Gears refer to mechanical elements with gears on the rim that continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. The principle of the gear cutting method and the special machine tools and tools that use this principle to cut gears have appeared one after another. With the development of production, the stability of gear operation has been paid attention to. At this stage, the gear industry should improve the industry concentration through market competition and integration, and form a group of leading enterprises in vehicle transmission systems through the design and development of products with independent intellectual property rights.
