Also known as a cross joint or universal joint, the English name is universal joint. It is a mechanical part that realizes variable angle power transmission and is used to change the position of the transmission axis direction. It is the "joint" component of the universal transmission device in the automotive drive system. The cross axis rigid universal joint is a widely used non constant velocity universal joint in automobiles, allowing the maximum intersection angle between adjacent axes to be between 15 ° and 20 °. The cross axis is one of the key components of the cross axis rigid universal joint.

The core advantages of the cross axis universal joint are reflected in three aspects: structural design, transmission performance, and applicable scenarios, as follows:
Simple structure and easy maintenance
Adopting a cross axis structure, a universal joint is installed at each end of the transmission shaft to ensure that the angle between the two ends of the transmission shaft is equal and avoid damage to the shaft components due to angle changes. Its compact design reduces manufacturing costs while facilitating installation, disassembly, and maintenance.
High transmission efficiency, suitable for high-power scenarios
The transmission efficiency can reach 98-99.8%, suitable for high-power transmission systems (such as heavy-duty vehicles and metallurgical equipment), with significant energy-saving effects. Some models (such as SWC type) adopt an integral fork head design, further improving the load-bearing capacity and transmission reliability.
Strong angle compensation capability, adaptable to complex working conditions
Allow the maximum intersection angle between adjacent axes to reach 15-20 degrees, meeting the requirements of space constrained equipment. For example, in equipment with the same rotation diameter, the cross axis universal joint can transmit greater torque, expanding the matching range.
Good durability and low noise
Made of high-quality alloy steel material (such as 40Cr), it has strong wear resistance and long service life. Good vibration and noise control during operation, suitable for long-term stable work.
