Re: Differential?
((If you were to build a drivetrain that utilizes an "Open Differential", and if you were to lift one of the wheels off of the carpet, the wheel off of the carpet would receive all of the torque and it would spin. The other wheel (on the carpet) would receive no torque and would not move.))
I agree completely but suggest that both outputs from the differential transmit 'equal' torque. By that I mean that both wheels get the same amount of torque, but, because the wheel in the air only requires say .2 ft/lbs to turn it due to lack of resistance, that same .2 ft/lbs of torque at the other wheel is not enough to cause that wheel to rotate. So when the free spinning wheel gets brakes applied, the amount of torque required to turn it increases (at both wheels) until the wheel with good traction is easier to rotate than the now stopped wheel, and the vehicle moves.
Same effect but just a different explanation.
