Continuously variable transmission and a working machine

Abstract

A continuously variable transmission has an input shaft and an output shaft. The transmission includes a variator unit having an input shaft and an output shaft, and a planetary gear wheel unit having a planet carrier, a first sun wheel and a second sun wheel. The input shaft of the transmission is rotationally connectable to the planet carrier and to the input shaft of the variator unit, and a shaft rotationally fixed to the first sun wheel is rotationally connectable to the output shaft of the variator unit. The planet carrier is provided with a first inner set of planet wheels for meshing engagement with the first sun wheel and a second outer set of planet wheels for meshing engagement with the second sun wheel. The first and second sets of planet wheels are in meshing engagement with each other, and a shaft rotationally fixed to the second sun wheel is rotationally connectable to the output shaft of the transmission via a first output member for obtaining a powersplit mode in which power is transmitted via the second sun wheel.
