Meaning and Definition
A mechanical coupling (universal joint) that allows rotational power to be transmitted between two shafts that are not in a straight line.
A specific type of universal joint named after Gerolamo Cardano (Jerome Cardan), though its invention predates him. It is a double-pivoted joint that allows a shaft to transmit rotary power at an angle. In automotive contexts, it's a key component of a driveshaft.
Dialectal Variation
British vs American Usage
Differences
The term is internationally recognized in engineering. 'Universal joint' is more common in general and automotive American English; 'Cardan joint' is slightly more formal/technical in both varieties.
Connotations
Technical precision. In the UK, it may be associated with formal engineering diagrams; in the US, it is strongly linked to automotive repair manuals.
Frequency
Low frequency in general language. Higher frequency in mechanical engineering, automotive, and industrial design texts. 'Universal joint' is the more frequent everyday term.

- Confusing it with a constant-velocity (CV) joint, which is a different, more advanced design.
- Using it as a general term for any flexible coupling.
FAQ
Frequently Asked Questions
Yes, 'Cardan joint' is a specific type of, and often used synonymously with, 'universal joint', particularly the Hooke's joint design common in automotive driveshafts.
Typically on the driveshaft (or prop shaft) of a rear-wheel or four-wheel-drive vehicle, connecting the transmission to the differential.
A single Cardan joint does not provide constant velocity; it causes slight speed fluctuations in the driven shaft, which can cause vibration, especially at higher speeds or sharper angles. This is solved by using two joints or a constant-velocity (CV) joint.
It was described by Gerolamo Cardano in the 16th century, but the concept was known and used earlier. Robert Hooke later studied and popularised its design in the 17th century, hence the alternative name 'Hooke's joint'.
A mechanical coupling (universal joint) that allows rotational power to be transmitted between two shafts that are not in a straight line.
