I don't understand your use of the word "axis" in terms of the gearing. Everything is spinning about a single axis in the differential.

The documents explicitly mention that the power comes in on the planet gears, the ring gear (aka planetary carrier) drives the rear wheels, and the sun gear drives the fronts. When there is a speed difference between the sun and ring gears the faster gear is pressed into the clutch pack, slowing it and preventing a "run-away" use of the engine's power. The bigger the speed difference, the harder the clutch is used, with the DCCD setting acting like a gain value to amplify the clutch use (at 100% lock, any speed difference is translated into clutch use, at 0% lock the clutch is never used).

If the clutch really works the way you're implying, then anytime the you're driving, even w/ plenty of traction, if the DCCD is locking at all, then you're slipping the DCCD clutch. That thing would wear out in a year!

As far as the quote from the document, at 100% lock, and slippery condition, the observed torque at the wheels would be 50/50, but it would be less than the normal total torque at the wheels... since it really would be 35%/35% with the remainder of the power being wasted heating the clutch.
