ABSTRACT:
An electrically variable transmission includes an input member to receive power from an engine about a primary axis; an output member connected to a transfer member for transmitting power to a secondary axis; first and second motor/generators; first and second torque transfer devices; and first and second planetary gear sets each having first, second and third members. The input member is continuously connected to the first member of the first gear set, and the output member is continuously connected to the first member of the second gear set. The first motor/generator is continuously connected to the second member of the first gear set. The second motor/generator is continuously connected with the third member of the first or second gear set. The transfer member is positioned between the first and second motor/generators.
