Differential Averaging Transmission

[nova_robotics]

Anybody interested in new types of transmissions and geartrains?

I came up with this a couple years ago as an alternative to CVTs. The idea is the power is split between two very simple gearsets, then power is recombined by averaging both output shafts in a differential-run-backwards. This allows lots of really cool things, including a ton of forward ratios with very few mechanical parts, and free low range. I have attached a PDF if anybody is interested in the details. The configuration in the image below is of a 15 speed transmission with 6.72 first gear.

Unfortunately R&D budgets for combustion vehicle has dropped to zero, so I don't think this will ever get built.
