Brief Introduction of Automotive Constant Velocity Joint Induction Heat Treatment Process

Why does the car universal joint need heat treatment?
Today's cars take the overall layout of the engine front and front wheel drive, the front wheel is both the steering wheel and the drive wheel. As a steering wheel, it is required to rotate an arbitrary angle within the maximum angle range; as a driving wheel, the driving shaft is required to continuously drive power from the final reducer during wheel deflection and the vertical movement of the wheel relative to the final drive. Passed to the drive wheel. Therefore, the drive shaft cannot be made integral and is to be segmented, and the universal joint is used to adapt to the change of the angle of intersection of the drive shafts during driving. In order to ensure uniform angular velocity change at both ends of the drive shaft, the universal joint must be able to achieve constant speed transmission, that is, constant velocity joint (CVJ). Since most of the front wheels of modern cars use independent suspensions, an isosceles joint is required near and near the differential, and its function is to transmit the torque transmitted by the engine through the transmission to the drive wheels evenly. At the same time, the axial expansion and steering requirements due to wheel runout are also met.
 
Characteristics of induction heat treatment:
1. The induction quenching process reduces the quenching deformation, and the workpiece is not heated as a whole, and the deformation is small.
2. The workpiece heating time is short, and the surface oxidative decarburization is small.
3. The surface hardness of the workpiece is high, the notch sensitivity is small, and the impact toughness, fatigue strength and wear resistance are greatly improved. Conducive to the potential of materials, saving material consumption and improving the service life of parts.
4, the process reproducibility is good, that is, good repeatability, consistency cylinder.
5, easy to achieve local quenching (the same for large parts).
6, the equipment is compact, easy to use, and good working conditions.
7. Easy to mechanize and automate. The process of induction heating is divided into three parts: the power frequency current is converted into an alternating current, and the alternating current generates an alternating magnetic field-alternating magnetic field to generate an eddy current to achieve heating effect.
