ABSTRACT:
A limited slip differential includes a mechanism for producing a varied bias ratio as a result of changes in side gear torque. An annular drive flange is biased toward frictional locking means within the differential case to provide biasing as required. The flange contains a first cam surface mateable with a second cam surface disposed on the back face of one of the side gears. Either the first or second cam includes a variable pressure angle, whereby a varied biasing force is developed on the drive flange as the side gear moves relative to the flange via changes in side gear toque.
