Same thing applies to dogbones
It's a difficult concept to describe. However, this explains brilliantly why the input velocity is indeed different to the output velocity.
Whilst the input and output rotations per minute are the same, each rotation of the output speeds up and slows down, depending on the angle of the plane that the output has to rotate through.
Our 'CVD's' are not constant velocity joints for that, we would need Rzeppa joints. Or something like this:
Constant Velocity Joints - Uber Ball Drive
The fact remains that MIP style 'CVDs' function in exactly the same way as a Cardan joint. Really the only difference is the rebuildable nature of the MIP style joint.
