Abstract
A torque vectoring gear drive apparatus for controlling drive torque distribution. The gear drive apparatus comprises an input shaft, first and second output shafts, a planetary interaxle differential unit for transmitting torque from the input shaft to the first and second output shafts, and a speed gear assembly provided for overriding said planetary interaxle differential unit. The planetary differential unit includes a planet carrier drivingly coupled to the input shaft and rotatably supporting at least one planet gear, a sun gear drivingly coupled to the at least one planet gear and a ring gear drivingly coupled the first output shaft, the sun gear drivingly coupled to the second output shaft. The speed gear assembly selectively couples the input shaft to the sun gear to define a first drive mode in which the sun gear is driven at a first speed.
