Our vehicle axle system mainly consists of the following parts:
I. Front Axle (Steering Axle)
• The front axle is located at the front of the vehicle and is a key device connecting the frame and the front wheels. It mainly bears the steering function and some vertical loads. Some Beiben models use front-wheel drive to transmit power.
• Core Components:
Front Axle Beam;Steering Knuckle (Knuckle Shaft);Wheel Assembly;Brakes;Kingpin and Steering Tie Rod Interface

Ⅱ.Mid-axle (Drive Axle)
In 6x4, 8x4, and other drive configurations, the mid-axle is the center of power transmission and distribution, connecting the transmission and rear axle to achieve multi-axle coordinated drive.
• Main functions: Bears the load in the middle of the frame, amplifies the torque from the driveshaft and transmits it to the wheels, and is the vehicle's main power output axle.
• Core components: Driveshaft assembly; final drive; differential; wheel-side reducers; half-shafts; braking and stability system
Ⅲ. Rear Axle (Drive Axle)
In 4x2 vehicles, it serves as a single drive axle. In 6x4 and other vehicles, it forms a tandem drive axle (commonly known as the "rear axle" or "rear dual axle") with the middle axle, providing the final guarantee of driving power.
• Main Function: Similar to the middle axle, it is the most crucial load-bearing and drive unit of the vehicle. In a tandem axle, power is transmitted from the middle axle to the rear axle via a through shaft (axle drive shaft).
• Core Components: Its components include the axle housing, final drive, differential, half-shafts, wheel-side reduction gears; and inter-axle differential and locking mechanisms.
