We all know that the universal joint for truck is used in the drive system. Let's take a look.

In front-drive vehicles, each half shaft uses two constant velocity universal joints. The universal joint near the transaxle is the inner universal joint of the half shaft, and the outer universal joint of the half shaft is near the axle. In a rear-drive car, the engine, clutch, and transmission are installed on the frame as a whole, and the drive axle is connected to the frame through an elastic suspension. There is a distance between the two and needs to be connected. During the operation of the car, uneven road surface bounces, load changes, or the position difference between the two assembly installations, etc., will cause the angle and distance between the transmission output shaft and the input shaft of the drive axle final reducer to change, so driving the car behind The universal joint transmission form adopts double universal joints, that is, there is a universal joint at each end of the transmission shaft. Its function is to make the angle between the two ends of the transmission shaft equal, so as to ensure that the instantaneous angular velocity of the output shaft and the input shaft are always equal.

The choice of the universal joint is more difficult, we don't have to worry about which model universal joint to choose when choosing custom universal joints .
