Abstract
A modulating limited slip differential is disclosed of the type including a gear case (11), an actuating mechanism (51) being operable to apply a force to a clutch pack (41) to retard rotation between a side gear (25) and the gear case. The actuating mechanism includes an outer actuating plate (55) which normally rotates at the same speed as the gear case. The differential includes an electromagnetic actuator (81) which is operable to cause rotation of the outer actuating plate relative to the gear case, resulting in ramping of a plurality of cam balls (79) and axial movement of an inner actuating plate (53) to load the clutch pack. The cam balls are disposed in openings (69) in an end wall (67) of the gear case, the openings being circular, and just slightly oversized, relative to the cam balls to maximize the amount of metal in the end wall, and therefor, the torque transmitting capacity of the gear case.
