what is the rear axle

The rear axle refers to the rear drive shaft component of the vehicle power transmission. It consists of two half-bridges that allow differential motion of the half-axles. At the same time, it is also a device used to support the wheels and connect the rear wheels. If it is a vehicle driven by the front axle, then the rear axle is just a follow-up axle, which only plays a bearing role. If the front axle is not a drive axle, then the rear axle is a drive axle. At this time, in addition to the bearing function, it also plays the role of driving and decelerating, as well as differential speed. If it is four-wheel drive, it is generally equipped with a splitter in front of the rear axle. actuator. The rear axle is divided into integral axle and half axle. The whole axle is equipped with non-independent suspension, such as leaf spring suspension, and the half-axle is equipped with independent suspension, such as MacPherson suspension.
