What are the characteristics and functions of automobile drive shaft brackets
1. Low carbon steel has good plasticity, but low strength and hardness, good weldability and cold stamping process, and can be used to make various standard parts, bushings, containers, etc.;
2. High carbon steel has poor plasticity, high hardness, poor fatigue strength, poor machinability, insufficient toughness for shaft parts, and easy to break. This type of steel is suitable for making static pressure and wear-resistant parts, such as heavy rails and rolls. After proper heat treatment, springs, wire ropes and other parts that require high hardness and high wear resistance can also be made;
3. The main function of the automobile transmission shaft is to support the rotating body and transmit power. The working conditions are generally subject to alternating torque and tension and compression loads, and the journal and key parts are subject to large friction and wear. The failure modes are mainly fracture and local excessive wear, and the fracture includes fatigue fracture and overload fracture. Therefore, when selecting materials, the materials should have sufficient strength, stiffness and certain toughness, good wear resistance, high fatigue strength and good machinability. That is, the main shaft is required to have good comprehensive mechanical properties.
4. The medium carbon steel can obtain good comprehensive mechanical properties after proper heat treatment, and achieve parts with tough core and wear-resistant surface.
Center bearing composition
The central bearing is installed in the center of the bottom of the vehicle to support the drive shaft. It is composed of bearings, brackets, rubber pads and oil flingers. The good sealing performance of the bearings can ensure a long service life.
