So I had to go look at the TCVJ website tonight. (Awesome post though! What a great looking product...)
Constant velocity variable angle Joints - shaft angles to 40 degrees
Reduces energy loss by reducing friction, heat and vibration, especially in applications where motors and devices have angular misalignment as well as compound angular misalignment.
• Steel and paper rolling mills
• Diesel motors and pumps
• Electric motors and pumps
• Helicopter propeller shafts
• Large industrial off-Road vehicles
• Marine drive lines
Looks like they are all ready making them for off-road industrial applications. I'm assuming this means skidders, logging skids, ect. I like the setup, but it looks very complex... it would be a great upgrade if you could put a big boot over it to keep gunk out. I can just imagine a stone making it's way inside and destroying the guts to that thing.
Give it another year and I bet they will produce them in a size small enough for passenger vehicles... especially if they are as amazing as they claim to be... [almost] no friction when bent?... with everyone screaming about fuel economy, that's sure to get some kind of response!
