Looking at the torsen paper, it is entirely a friction device.
They derived a torque difference depending on the output torques
and a bunch of constants, angles of gear teeth, coefficients of
friction etc.. Nowhere did relative speed come into the picture.
Seems to me that if there is any speed differential at all,
then torque split will be at max with the slower turning
shaft getting the greatest torque, or put another way,
torsen resists speed differential up to the point of max
torque split at the output shafts, at which point, the
shafts slip relative to each other, still at max torque split.
Given this, I think we can remove any quantitative treatment of
speed differential and say if there is any speed differential,
max torque is going to the slower turning shaft.
This would be what those weasel paragraphs at the end of the paper
would be refering to. (I read the cornering paragraphs as
'It ain't so great when cornering'.)
