Abstract
A torque vectoring device for a vehicle drive module. The torque vectoring device includes an electric actuator and a planetary gearset. The planetary gearset includes a ring gear, a sun gear, a planet carrier, and at least one planet gear. The ring gear is rotationally coupled to a differential case of a vehicle drive module. The sun gear is operatively couplable to the electric actuator. The planet carrier is rotationally coupled to a first output shaft of the drive module. The at least one planet gear is rotationally supported by the planet carrier and engaged with the ring gear and the sun gear. The electric actuator is operable to bias torque between the first output shaft and the second output shaft of the drive module.
