ABSTRACT:
A differential system for transmitting power to a split pair of wheel axles utilizes a coupled pair of special planetary gear sets to proportion torque when the wheels negotiate a turn or lose traction. The gear ratio of each set is such that when the driving torque is in the speed increase mode of the gears, the two lock and rotate in the same direction but when the torque is on the sun gear caused by feedback due to negotiating a turn, the sun gear nutates within the ring gear to adjust for speed differentials. The sun gear of each set drives an eccentric cam on its associated wheel axle and is adapted to drive the ring gear of the opposite set by the provision of torque-transmission coupling therebetween.
