English: Drawings of a Thompson Constant Velocity Joint with colors added to help identify the parts; the second drawing removes several parts to show the central innovation which is a spherical pantograph that maintains both cardan joints in the homokinetic plane. Importantly, all of the rotating axes of: input shaft 27, output shaft 28, output pivot shafts X, control yoke pivot shafts Y, output shaft control pin A, input shaft control pin B, and control yoke pivot pin C all pass through the coupling center point 29. Images derived from US Patent 7,442,126.
