Differential Rear Half Shaft Gear for Sinotruk HOWO Steyr Parts 199014320059

The function of differential side gear:

1. The function of the differential is first to change the direction of power transmission and transmit power to the wheels on both sides through the half shafts. When the vehicle turns, the half shafts on both sides automatically rotate at different speeds so that the wheels roll as much as possible. Performing unequal distance movements reduces the resistance when turning and reduces tire wear.

2. The planetary teeth in the differential only rotate around the side gears. At this time, the speeds of the wheels on both sides are equal, the differential does not work, and the vehicle is traveling in a straight line.

3. The materials of side gears are generally alloy structural steel. Different models are different, and the steel materials are different in high, medium and low grades.

4. The half shaft is also called the drive axle. The half shaft is a solid shaft that transmits torque between the differential and the drive wheel. Its inner end is generally connected to the side shaft gear through splines, and the outer end is connected to the wheel hub.

5. The half-shafts commonly used in modern automobiles are divided into two types: full-floating and semi-floating according to their different support types.

6. The fully floating half shaft only transmits torque and does not bear any reaction force or bending moment, so it is widely used in various types of cars. The fully floating half-shaft is easy to disassemble and assemble. You only need to unscrew the bolts on the flange of the half-shaft to pull out the half-shaft, while the wheels and axle housing can still support the car, making car maintenance easier.

7. The semi-floating half shaft not only transmits torque but also bears all reaction forces and bending moments. Its support structure is simple and the cost is low, so it is widely used in various types of cars with small reaction bending moments. However, this kind of half-shaft support is troublesome to remove, and if the half-shaft breaks while the car is driving, it may easily cause the risk of the wheel flying off.
