What is cross shaft universal joint?

Introduction of drive shaft with u joints

The most core component of driving steering shaft is the universal joint at both ends. Whether the structure form and specificationbuy centered u joint shaft - xinsanming size of the universal joint are appropriate or not directly affects the performance and reliability of the driving shaft.

Universal joint (also known as coupling) is the joint of two axes with angular displacement changes (drive shaft and driven shaft), so that the torque on the active (input) shaft is transferred to the driven (output) shaft and rotation of the mechanical device.

The universal joint may be strange to most people, but its principle is very simple. That is, to ensure that its connected input and output shafts transfer power within a certain range of angular variation. There are many types of universal joints, so let's look at the cross-shaft universal joint.

Cross shaft universal joint is used for our car above the rotating shaft above, that is like our joint! It is composed of the structure as shown in the figure.

This structure has solved the problem of two-axis variable Angle transmission, but   its unequal speed will make the output shaft with the change of Angle to produce different speed changes. So, although flexible, but unstable ah! If you apply this form directly to cars, EMM... I don't think anyone dares to sit there!

The most extreme performance of this situation is when the engine gearbox casting speed is certain, the driving wheel is fast or slow, and there is torsion vibration. Of course, this is an extreme case. Therefore, a single cross shaft universal joint is not as useful in practice as imagined.

It's like two negatives make a positive. A constant input leads to a regular variable output, and a regular variable input leads to a constant output. This cross-shaft universal joint provides stability for the dynamic structure design and allows certain choice of steering position.
