Gleasman Torsen

["John Burk" <joyseydevil@comcast.net>]

Torsen differentials use worm gears to link the axel gears . It's based on the
fact that the friction of worm gears driven in the wrong direction goes up as
the torque increases . At one time and maybe still most of NASCAR , Indy and
F1 used Gleasman Torsen differentials . They were around a long time before
they found they were good for race cars .
