There is a very important part in a car, called a universal joint, which can also be said to be the universal joint for truck . The combination of universal joint and driveshaft is called universal joint transmission.

The universal joint for trucks is a component that realizes variable-angle power transmission. It is used to change the direction of the transmission axis to make the angles between the two ends of the transmission shaft equal, to ensure that the instantaneous angular velocities of the output shaft and the input shaft are always equal.

At present, the most widely used common universal joint in rear-drive vehicles is composed of basic parts such as universal joint forks and cross shafts. The cross shaft is assembled on the universal joint fork for connection. The shaft head of the cross shaft is equipped with a needle bearing. When the shaft head is connected to the universal joint fork, the cross shaft and the universal joint fork can rotate relative to each other. There is a multi-angle change. The spline connection on the universal joint fork can make a small amount of axial movement, to meet the needs of simultaneous changes in the angle and distance.

However, because there are too many types and models of universal joints, many people don’t know how to choose the most suitable universal joints when they first come into contact with universal joints, so choosing custom universal joints at this time should be the most convenient and quickest.
