RE: torsens & 'torque split'

[glen powell <gpowell@acacianet.com>]

Torque and 'torque split' are not related to the speed or relative
speeds of the two shafts with an open or a locked diff. The 'torque split' is purely a function
of the relative counterforce applied to each axle and this is a function of the relative
traction or lack of traction available at the two road/tire interfaces on the axle
in question. Equal traction = equal torque split. Zero traction at one wheel = zero
total torque and zero forward vehicle acceleration/motion with an open diff. Zero traction 
at one wheel = 0/100 'torque split' with a locked diff with the 100% going to the wheel 
with traction - exactly what you want if you want the vehicle to accelerate and move.
