Patent ID: 8808131

Claim:
A machine powertrain that includes an engine connected to a continuously variable transmission, the continuously variable transmission comprising: a planetary gear arrangement having first and second planetary gear sets, the first planetary gear set being connected to a planetary input, a sun gear of the second planetary gear set being connected to a first output shaft and a carrier gear of the second planetary gear set being connected to a second planetary output; a variator including a variable-speed prime mover, the variable-speed prime mover configured to drive a ring gear of the second planetary gear set; a transmission input shaft driven by the engine and configured to drive the variator and the planetary input; a second output shaft and a third output shaft, at least one of the second and third output shafts being connected to a transmission output shaft; a first clutch connected to the first output shaft; a second clutch connected to the second planetary output and configured to releasably engage a first drive gear, wherein the first drive gear is configured to rotate in an opposite direction relative to the third output shaft; a third clutch connected to the first output shaft and configured to releasably engage the first drive gear; a fourth clutch connected to the first drive gear and configured to releasably engage the second output shaft; and a fifth clutch connected to the first drive gear and configured to releasably engage the third output shaft, wherein the continuously variable transmission is configured to provide at least two forward-motion gear ratios and at least two reverse-motion gear ratios between the transmission input shaft and the transmission output shaft when one of the first clutch and the second clutch, and one of the third clutch and the fourth clutch, are simultaneously engaged.
