Abstract
A torque biasing differential including a planetary case rotatable about an axis, a first output shaft rotatable relative to the planetary case, a second output shaft rotatable relative to the planetary case and the first output shaft, and a planetary assembly coupling the planetary case to the first and second output shafts. The planetary assembly includes first and second intermeshed inboard planet gears. The differential also include torque sinks associated with each of the first and second planetary assemblies to selectively distribute torque between the output shafts and control relative shaft rotation. The various embodiments of the torque biasing differential also describe alternative planetary differential configurations relating to the structure, orientation, and interaction of the sun gears, planet gears, and case.
