After the popularization of automobiles, many parts merchants have gradually developed, among which is the universal joint manufacturer . Today we will take a look at the universal joint.

The universal joint is mainly researched and developed based on the double cross-axis universal joint. Except for the double-cross shaft, universal joints, the bump type universal joints, and the three-pin type universal joints work exactly the same as the double-cross shaft universal joints, except that the intermediate driveshaft and the cross shafts at both ends are evolved into Bump or three pins. The couplings of these two structures are simple and reliable, and the allowable shaft angle is relatively large. Due to their low transmission efficiency and easy wear, the solid use range is limited.

The cross shaft universal joint is the first universal joint used in production practice, and it is also the most widely used one. The main components of a cross-shaft universal joint are composed of active and passive forks and a cross shaft, and the middle force component that transmits power is the cross shaft. Utilizing the characteristics of its structure, it can make two shafts that are not on the same axis or with a large bend angle of the axis continuously rotate at equal angular speed, and reliably transmit torque and motion.

Later, more universal joints appeared, as did the precision universal joint , and some bearings that did not require or a little maintenance appeared, making it more convenient to use.
