Abstract:
An electric drive unit (EDU) is configured for driving a first and second wheel of a vehicle. The EDU includes a rotor, a stator, a first planetary gear set, a second planetary gear set, and a pair of engagement mechanisms. The first planetary gear set is operatively connected to the rotor and rotates about the drive axis in response to rotation of the rotor to transmit torque to the first wheel. The second planetary gear set is operatively connected to the rotor and rotates about the drive axis in response to rotation of the rotor to transmit torque to the second wheel. Rotation of the rotor causes each of the planetary gear sets to rotate about the drive axis. Each engagement mechanism is selectively engages a respective one of the planetary gear sets to vary the torque transmitted to the respective wheel.
