Abstract
An electric axle drive utilizes an electric motor to propel both half-shafts via final drive gearing and a differential. Torque vectoring gearing alters the torque distribution by transmitting power from one of the half shafts to the motor or from the motor to the half-shaft in response to engagement of brakes. Both the final drive gearing and the torque vectoring gearing are implemented using stepped planetary gear sets. The final drive gearing and differential are located on one end of the electric motor. The torque vectoring gearing is located on the opposite end of the electric motor.
