Abstract
A front differential for a four wheel drive vehicle including a pinion assembly with first and second pinions that are engaged with a ring gear assembly with first and second ring gears. The first pinion and first ring gear combination are rotatable independent from the second pinion and second ring gear combination, thus permitting one to rotate relative to the other. The first pinion and first ring gear combination are adapted to rotate one driven shaft, and the second pinion and second ring gear combination are adapted to rotate the other driven shaft. A bi-directional overrunning clutch assembly is engaged with an end of the drive shaft and includes one set of rolls located adjacent to the first pinion shaft, and another set of rolls located adjacent to the second pinion shaft. The clutch assembly control torque transmission between the pinion shafts and the drive shaft.
