Abstract
A differential mechanism usable as an inter-axle differential or as a conventional axle differential includes a carrier mounted for rotation in a differential housing. The carrier rotatably mounts a pair of face-type side gears located in a spaced apart, confronting relationship. A plurality of spur-type pinion gears are rotatably mounted within said carrier; the spur-type pinion gears are in meshing co-engagement with the confronting side gears and have radial axes of rotation with respect to the rotational axis of said carrier. Thrust/friction washers are disposed between the carrier and each face gear and provided limited slip capability to the differential. The differential can easily accommodate variations in torque split by installing unequally sized side gears. Changing the side gears does not require changing the size of the pinion gears to achieve other than 50/50 torque split between axles that are connected to the carrier.
