Abstract
A limited slip differential includes a friction clutch mechanism, an electromagnetic coupling, and a camming mechanism disposed between the friction clutch mechanism and the electromagnetic coupling. The camming mechanism converts shearing forces within the electromagnetic coupling to an axial force applied to engage the clutch mechanism. The camming mechanism includes annular discs having axially inclined ramps, and a roller bearing for movement along the ramps to provide for variable spacing between the annular discs, wherein increased spacing is used to apply the axial force.
