Forklift steering column universal joint is the joint between steering column and steering linkage. Forklift universal joints are a bit like the joints on the human limbs, it allows the angle between the connected parts to change within a certain range.
The function of the steering column universal joint 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. There are also other universal joints on the forklift drive system, which is connected to the transmission shaft and has a similar function.
