Not a Differential
Jnadke,

What you describe in your design theory section is exactly what the CCT is with using bevel gears. The differential without the second gear, as you describe, is not a differential at all. It is a planetary gear set. As you describe it, it would work EXACTLY like the CCT from 217, but it is not a differential. By definition, when you remove the second inside bevel, it is no longer a differential.

I will put together a little paper showing the physics (with numbers and equations) behind Tytus' gearbox design, but I am fairly confident it will behave as Bill Beatty and I have described.
