<p>A limited slip differential axle assembly includes a plurality of pressure plate segments which are electromagnetically biased against friction discs of clutch packs secured to side gears of the differential. In a preferred form, the assembly is formed of a two-piece of "split" differential case and includes an armature ring rigidly coupled to a pressure plate loading ring. Electromagnetic coupling forces are adjustably controlled by a vehicular operator to permit modulation of bias for given road conditions, wherein a limited slip differential control may be effective to bias a clutch pack to provide a variable friction drag between at least one of the side gears and the differential case. For this purpose, an energizing coil is secured rigidly to the differential carrier, while a magnet shell member is rigidly affixed to one part of the split differential case. The armature ring cooperates with the magnet shell to form an air gap, the armature ring being threadably and hence adjustably secured to the loading ring disposed between the two relatively moveable parts of the split differential case.</p> |
