Abstract:
A continuously variable transmission includes a variator unit having a variator input shaft and a variator output shaft, and first, second and third planetary gear sets. The first and second planetary gear sets are arranged together and each includes a first member operatively connected to a common transmission input shaft and a second member operatively connected to a common output shaft, each of the first and second planetary gear sets further including a third member. The third planetary gear set has a first, second and third member. The variator input shaft is operatively connected to the third member of the second planetary gear set and the variator output shaft is operatively connected to the third member of the first planetary gear set. The first member of the third planetary gear set is operatively connected to the variator output shaft. The second member of the third planetary gear set is selectively connectable to the third member of the second planetary gear set and selectively connectable to the transmission housing. The third member of the third planetary gear set is operatively connected to a transmission output shaft. The common output shaft is selectively connectable to the transmission output shaft.
