Rear axle refers to the rear drive shaft component of vehicle power transmission. It consists of two half-bridges, which can implement half-bridge differential motion. 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 only a follow-up axle and only serves as a load bearing. If the front axle is not a drive axle, then the rear axle is a drive axle. At this time, in addition to the load bearing function, it also plays the role of driving, deceleration and differential speed. If it is a four-wheel drive, there is generally a sub-drive in front of the rear axle. Actuator. The rear axle is divided into a whole bridge and a half bridge. The whole bridge is equipped with a non-independent suspension, such as a leaf spring suspension, and the half bridge is equipped with an independent suspension, such as a MacPherson suspension.
The rear axle of a car refers to the bridge behind the car.
If the front axle is not a drive axle, then the rear axle is a drive axle. At this time, in addition to the load bearing function, it also plays the role of driving, deceleration and differential speed. If it is a four-wheel drive, there is generally a sub-drive in front of the rear axle. Actuator.
The front axle and the rear axle refer to the front and rear axles. The front axle includes shock absorber springs, steering gears, balance shafts, etc., and the rear axle also includes drive shafts, transmission gears, and so on. The rear of a multi-axle truck is divided into a drive rear axle and a driveless rear axle. The driveless rear axle is the part that is not connected with the drive shaft and is not part of the drive wheel. It is generally only available for heavy trucks and tractors with more than 3 axles.
Basic principle of work
The engine transmits power to the gearbox, and then to the large chainring of the rear axle through shifting. The differential is a whole, inside: there are small gears on the top and bottom, there is a cross column in the middle, there are two asteroid gears on the top (acting for turning speed regulation) The differential is placed upright, with two small circles on both sides Hole, there is a feather key on it, we often say that the half column is inserted in it. The cross column does not move when walking in a straight line, and the cross column moves when turning to adjust the speed of the tires on both sides to improve the maneuverability of the car when turning.

The rear axle of the Jiefang truck is a drive axle, and its main functions are:
(1). The engine sends out the power from the clutch, gearbox and drive shaft through the reducer to reduce the speed and increase the torque, and transmit this torque to the drive wheels through the half shaft;
(2). Bear the load of the rear axle of the car;
(3). The reaction force and moment of the road surface are transmitted to the frame through the leaf spring;
(4). When the car is running, the rear wheel brake plays the main role of braking, and when the car is parked, the rear wheel brake produces the parking brake.
