Abstract
A powertrain includes an engine and a continuously variable transmission including a planetary gear arrangement and a variator. An input drives the variator and the planetary gears. A first planetary output gear is connected to the first output of the planetary gear arrangement. A second planetary output gear is connected to the first output, and a third planetary output gear is connectable by a first clutch to a second output of the planetary gear arrangement. A first output member is connected to the third planetary output gear, a second clutch releasably connects the first output member with the first planetary output gear, a third clutch connects the first output member with the second planetary output gear, a fourth clutch connects the second output member with the first planetary output gear, and a fifth clutch connects the second output member with the second planetary output gear.
