Abstract
A torque vectoring apparatus receiving a vehicle driving torque from a motor-generator may include a speed reduction device engaged to the motor-generator and configured to reduce a rotation speed received from the motor-generator, a differential device engaged to the speed reduction device and configured to receive the speed-reduced torque from the speed reduction device and to differentially output torques to left and right output shafts, a vectoring control motor outputting a control torque, and a torque vectoring apparatus engaged to the vectoring control motor and including two planetary gear sets and controlling a torque ratio output to the left and right output shafts by the control torque of the torque vectoring control motor, wherein the differential device includes a differential case receiving a torque from the speed reduction device, the differential case is mounted between the two planetary gear sets rotatably on a connecting member connecting the two planetary gear sets, and side gears in the differential case are fixedly connected to the two planetary gear sets respectively.
