Technically defined as internal joint with swivel axial movements. There are two types of Inner cv Joint, the first one is the combination of cage-spheres-core solution that contribute to preventing the vehicle’s shaking by eliminating the axial forces generated internally. The second one is the tripoidal solution that allows the motion’s transmission with high torque values. The second solution include the fixed and pivot roller, the latter is even allowing the GAF (Generated Axial Force) reduction of 38% compared with the fixed roller solution.
