Abstract
An axle center for delivering engine torque to two axle shafts which in turn transfer the torque to road wheels includes a torque coupling though which the torque is transferred to the axle shafts. The coupling includes a magnetic particle clutch and a planetary set organized about a common axis and coupled together such that two paths—a mechanical path and a clutch path—exist in the coupling for transferring torque through it, with the amount of torque transferred being dependent solely on the current in the magnetic particle clutch. A single torque coupling may be located where torque is delivered to the axle center or two torque couplings may be located at and connected to the two axle shafts, one for each shaft.
