Abstract
A planetary differential continuously variable transmission is provided having a first drive input ring gear having internal teeth, and a planetary differential connected to the first drive input ring gear, A first electric machine is provided having a first stator and a first rotor, with the first rotor being connected to the first drive ring input ring gear. A second electric machine is provided having a second stator and a second rotor, with the second rotor being connected to the planet gear carrier of the planetary differential and acts as a second drive input. A one way clutch is located between the second stator and the second rotor to limit a reverse rotation of the second rotor in order to improve efficiency and save battery life in electric or hybrid vehicles with this drive system.
