Patent ID: 8771127

Claim:
A differential output control apparatus, comprising: a differential, comprising: a carrier gear, wherein the carrier gear is fixedly coupled to a cage and meshingly engaged with a system input/output shaft B; planet gears consisting of two planet gears rotatably coupled to each of two opposing cage sidewalls; sun gears consisting of: a first sun gear coupled to a first application shaft A, and meshingly engaged with both of the two planet gears; a second sun gear opposite the first sun gear and coupled to a second application shaft C, and meshingly engaged with both of the two planet gears; wherein the first and second application shafts A and C extend in opposite directions away from the first and second sun gears, respectively; a first interface, wherein the first interface is positioned on the first application shaft A opposite the first sun gear, and wherein the first interface is adapted to engage a rotating device output; a second interface, wherein the second interface is positioned on the second application shaft C opposite the second sun gear, and wherein the second interface is adapted to engage a controlled rotating output; wherein a relationship between a speed V B of input/output shaft B, a speed V A of first application shaft A, and a speed V C of second application shaft C is V A +V C =2V B ; at least one adjustable mechanical link coupling two linked differential inputs, the two linked differential inputs comprising the system input/output shaft B and the first application shaft A, wherein the adjustable mechanical link is configured to turn A and B in a same direction and to adjust a relative rotation speed of the two linked differential inputs according to a ratio k so that V B =kV A and V C =V A (2k −1); and an electronic adjustable mechanical link control system adapted to control the controlled rotating output produced at the second interface at least in part by: calculating, for a given rotating device output engaged at the first interface, an adjustment setting for the adjustable mechanical link; and sending, via a communication link, electronic control signals to the adjustable mechanical link to adjust the adjustable mechanical link to the calculated adjustment setting, to thereby control the controlled rotating output at the second interface.
