Abstract
A controllable differential having a rotatable casing, differential gearing disposed within the rotatable casing and linking the casing with an output element disposed therein, a clutch disposed within the rotatable casing and clutch adapted to transfer torque between the rotatable casing and the output element, and an electromagnet arranged to generate a generally toroidal magnetic flux path encircling the electromagnet and magnetically forcing the clutch into engagement with the rotatable casing, the casing including a nonmagnetic portion adjacent the electromagnet, said flux path surrounding the nonmagnetic casing portion.
