The Thompson constant velocity joint (TCVJ), also known as a Thompson coupling, is a constant velocity [[universal joint]] that can be loaded axially and continue to maintain constant velocity over a range of input and output [[Drive shaft|shaft]] angles with low friction and vibration. It consists of two cardan joints assembled within each other, thus eliminating the intermediate shaft, along with a control yoke that geometrically constrains their alignment. The control yoke maintains equal joint angles between the input shafts and a relative phase angle of zero to ensure constant angular velocity at all input and output shaft angles. While the geometric configuration does not maintain constant velocity for the control yoke (aka intermediate coupling) that aligns the pair of cardan joints, the control yoke has minimal inertia and generates virtually no vibration. -->
<!-- Q: so why is the second joint needed then? A: To maintain the geometric alignment of the two cardan joints. -->
<!-- Eliminating the intermediate shaft and keeping the input shafts aligned in the homokinetic plane virtually eliminates the induced [[shear stress]]es and [[vibration]] inherent in traditional [[Universal_joint#Double Cardan Shaft|double cardan shafts]].<ref name = "Sopanen">{{cite web | url = http://www.ee.lut.fi/static/fi/lab/sahkokaytot/sameko/Cardan_Sameko.pdf | title = Studies on Torsion Vibration of a Double Cardan Joint Driveline | last = Sopanen | first = Jussi| date = 1996 | accessdate = 2008-01-22 }}</ref><ref name = "Sheu">{{cite web | url = http://cat.inist.fr/?aModele=afficheN&cpsidt=3004428 | title = Modelling and analysis of the Intermediate Shaft Between Two Universal Joints | last = Sheu | first = P| date = 2003-02-01 | accessdate = 2008-01-22 }}</ref>
