1. Steering axle: consists of two steering knuckles and a cross beam; Function: Use the swing of the steering knuckle to deflect the wheel to a certain angle to realize the steering of the car; Bear the vertical load, longitudinal road resistance, braking force and lateral force between the wheel and the frame and the torque formed by these forces; The steering wheel has a correct positioning angle and a suitable steering angle.
2. Drive axle: it consists of main reducer, differential, half axle and axle housing; The driving force from the engine is transmitted to the driving wheel, which realizes the function of reducing speed and increasing torque and changes the direction of power transmission.
3. Steering drive axle: it has two functions of steering and driving. It not only has the basic components of the general driving axle, but also has a unique steering axle kingpin. The structure of the steering drive axle not only has the main reducer, differential and half shaft of the general drive axle, but also has the steering knuckle housing, king pin and hub of the general steering axle.
4. Support axle: it belongs to the driven axle in essence. The rear axle of a three-axle automobile driven by a single axle is designed to support the axle on the trailer, which is the rear axle of an automobile driven by an engine with a front axle, and belongs to supporting the axle.
Periodic maintenance of axle:
1. Perform routine maintenance every 10000 km after the first maintenance.
2. Contents of regular maintenance: change lubricating oil, tighten fasteners, check toe-in, and check the wear degree of brake friction plates. If the wear limit is reached, it should be replaced in time and the brake clearance should be adjusted. Check whether the clearance between reducer assembly, driving gear and driven gear is too large and whether the gear oil exceeds the service efficiency. In similar situations, the clearance should be adjusted and the grease should be replaced in time.
