Abstract
A transmission system () including a transmission input shaft (), a transmission output shaft (), and three planetary gear sets (P, P, P) having a total of seven interface shafts (W-W). The planetary gear sets (P, P, P) are at least partially functionally connected to each other by planetary gear set shafts (S-HR), are at least partially connectable to each other through a plurality of shift elements (B, B, K-K; B-B, K-K), and are coupled to the seven interface shafts (W-W) by the planetary gear set shafts (S-HR) such that at least six gear ratios (VM-VM, RVM, RVM) are selectable such that the transmission input shaft () and the transmission output shaft () revolve with the same or different direction of rotation.
