Abstract
A universal coupling is provided that aims to achieve constant velocity between the input and output shafts. The universal coupling also aims to increase the angle between input and output shafts over conventional double Cardan joints while maintaining constant velocity or near constant velocity therebetween. The universal coupling can employ a Sarrus type linkage in-between two universal joints of the Cardan type in a configuration that aims to achieve joint angles up to and including 90 degrees in the Y-Z plane, while maintaining constant velocity or near constant velocity therebetween.
