Abstract

A limited slip differential comprises a bevel gear differential having side gears and planet gears carried by a planet gear support which is capable of limited rotation relative to the carrier. When the side gears carry unequal torques the support tends to rotate and moves a pressure ring axially due to complementary cam surfaces on the support and the ring and this engages a friction clutch which connects a viscous shear coupling between the side gears.
