If it is a front-axle driven vehicle, the rear axle only acts as a bearing. Generally speaking, there is a transmission box in front of the rear axle. The working principle of the rear axle is as follows: 1. The engine transmits power to the gearbox, and then to the big gear (differential) of the rear axle through the gearbox; 2. The differential is a whole, consisting of two small toothed discs and ten pillars in the middle. There are also two small star gears (for steering and speed regulation); 3. The differential is vertical, with two small round holes on both sides and sliding keys. When driving in a straight line, the ten pillars don't move, but when turning, the ten pillars will move, adjusting the speed of the tires on both sides, thus improving the turning ability of the car.

Of course, power steering also has a certain impact on the safety and economy of automobile driving. The maintenance price of Geely Emgrand's rear axle is between 1000-2000 yuan.
