Automobile rear axle (also known as drive axle) refers to the rear drive shaft and related components used to transfer automobile kinetic energy. The rear axle of an automobile needs to carry the weight of the rear axle of the automobile, reduce the speed, drive the vehicle and realize the differential movement of the half axle.
The working principle of automobile rear axle is: the engine converts the heat energy generated by fuel combustion into kinetic energy, that is, torque, which gradually decreases in speed and increases in torque during transmission through clutch, reducer and other devices; Finally, the torque is transmitted to the wheel through the half axle to drive the wheel. The driven spiral bevel gear on the main reducer cooperates with the driving spiral bevel gear to form a gear pair, which is used to change the transmission direction of torque. The figure is the schematic diagram of the rear axle (drive axle) of a certain type of automobile.
As the main transmission component of the main reducer system, the main driven and driven spiral bevel gear needs to bear the impact of variable amplitude load in high temperature and harsh working environment for a long time. Consumers’ urgent desire for safe and smooth driving of vehicles makes the main engine factory put forward more and more strict requirements for the product quality, accuracy and mechanical properties of gears.
