Abstract

A transmission system (1) including a transmission input shaft (2), a transmission output shaft (3), and three planetary gear sets (P1, P2, P3) having a total of seven interface shafts (W1-W7). The planetary gear sets (P1, P2, P3) are at least partially functionally connected to each other by planetary gear set shafts (S1-HR3), are at least partially connectable to each other through a plurality of shift elements (B1, B2, K1-K3; B1-B3, K1-K3), and are coupled to the seven interface shafts (W1-W7) by the planetary gear set shafts (S1-HR3) such that at least six gear ratios (1VM-6VM, R1VM, R2VM) are selectable such that the transmission input shaft (2) and the transmission output shaft (3) revolve with the same or different direction of rotation.
