Abstract
A differential apparatus for controlling the wheel speed of a vehicle includes a primary driving input, and first and second output shafts. The differential apparatus also includes a first planetary gear system in driving engagement with the first output shaft for rotating the first output shaft, and a second planetary gear system in driving engagement with the second output shaft for rotating the second output shaft. At least one auxiliary input mechanism selectively drives the first and second planetary gear systems for rotation in opposite directions to effect different rotational speeds to the first and second output shafts, thereby controlling the wheel speed of the vehicle.
