Constant velocity (CV) wide angle universal joint assemblies allow for smooth machine operation through a broad range of motion. The universal joints included allow the machine to be designed with the input shaft in the best operating position and yet allow the operator to maneuver as needed. The CV delivers constant power by self-canceling torque and speed fluctuations typically found in single cardan-type universal joints.
