What Components Make Up the Rear Axle of a Vehicle?
1 Answers
Rear axle consists of the drive shaft and transmission gears. The rear axle of a vehicle refers to the axle located at the rear. In front-wheel-drive vehicles, the rear axle merely serves as a trailing axle, primarily bearing the load. Below is an introduction to the impact of replacing the rear axle on a car and the functions of the rear axle: Impact of replacing the rear axle on a car: The rear axle affects the four-wheel alignment data of the vehicle. Some vehicles adjust wheel data based on the rear axle. If the rear axle of a sedan is deformed or the rear axle shaft is bent, it not only causes the load to concentrate on the inner shoulder of the inner tire during driving but also reduces the tire's contact area with the ground, increasing the pressure per unit area and accelerating wear on the inner tire. Additionally, the vehicle may sway from side to side during driving, leading to sawtooth or irregular wear on the tire shoulders. Functions of the rear axle: The power transmitted from the clutch, gearbox, and drive shaft is reduced in speed and increased in torque through the reducer, which then transfers this torque to the drive wheels via the half-shafts. It bears the load of the rear axle. The reaction forces and moments from the road surface are transmitted to the frame through the leaf springs. During driving, the rear wheel brakes play a major role in braking, and during parking, the rear wheel brakes provide the parking brake function.
