Product Description
Automobile semi-axle is an important part in the transmission system, which is mainly used to transfer the power generated by the engine to the wheels and realize the driving of the vehicle. Automobile axle usually consists of the following components:
1. Axle tube (axle tube): The axle tube is the main part of the axle shaft, which is usually made of high-strength alloy steel and has sufficient strength and rigidity to bear the torsional force and load of the transmission system. The design and manufacturing quality of axle tube directly affects the service life and safety performance of axle shaft.
2. Joints: Joints are usually installed on the axle shafts, which are used to connect between the axle shafts and the wheel bearings to realize the transmission and steering functions of the transmission force. Common joint types include CV joint (constant velocity universal joint) and ball joint, and their design and manufacturing quality directly affect the transmission efficiency and stability of the semi-axle.
3. Bearing: A bearing will be installed on the half shaft to support the rotation of the half shaft and reduce friction and wear. Bearings are usually made of high-strength alloy steel or special alloy, which has good wear resistance and corrosion resistance.
4. Gears (if any): In the transmission system of some models, gears may also be installed on the axle shaft to transmit power and realize the differential function of different wheels. Gears are usually made of alloy steel with high strength and wear resistance.
5. Seals: In order to prevent dust, moisture and impurities from entering the half shaft and protect the normal operation of the half shaft, the half shaft is usually equipped with seals. Seals are usually made of rubber or silica gel, which has good sealing and durability.
To sum up, the composition structure of automobile semi-axle usually includes axle tube, joint, bearing, gear (if any) and seal. These components work together to realize the power transmission and steering functions, and ensure the normal driving and driving safety of the vehicle.
