universal joints

Angled shaft connectors

A universal joint is a mechanical coupling that transmits rotational power between shafts at an angle to each other.

The joint allows the connected shafts to bend and pivot while continuing to rotate—essential in automotive drive shafts, where the angle between transmission and axle changes as the suspension moves.

Often shortened to U-joint.
