摘要:
An electrically variable transmission having two planetary gear sets, two motor/generators, and six torque transfer devices to provide input split, compound split, output split, neutral, electric reverse and mechanical reverse modes of operation. The electrically variable transmission includes: an input member to receive power from an engine; an output member; first and second motor/generators; and first and second differentially geared planetary gear sets each having first, second and third gear members. The input member is not continuously connected with any member of the planetary gear sets, and the output member is continuously connected to the first member of the second planetary gear set. The first and second motor/generators are each continuously connected to at least one member of the planetary gear sets. The first member of the first planetary gear set is continuously connected with the third member of the second planetary gear set. The six torque transfer devices are selectively engageable to provide the various operating modes of the electrically variable transmission.
