Abstract

A gearbox assembly includes a housing which contains a differential gear set and a two-speed reduction gear set. A spider drives differential pinion gears nested between outer pinion gears. A first and a second clutch that can be engaged “on the fly” achieve the two-speed functionally of the gearbox assembly. Another gearbox assembly includes an on-demand locking differential with a differential clutch located between differential axle side gears to selectively lock the differential axle side gears together and thereby lock the axle shafts.
