Abstract:
A vehicle transmission with a drive shaft (AW), two transmission input shafts (GE1, GE2), at least one decoupling element (K2, X1), which is assigned to the second transmission input shaft (GE2), a main shaft (HW), an output shaft (AV) and at least three planetary gear sets (PG1, PG2, PG3). A respective subtransmission (TG1, TG2) is assigned to each of the transmission input shafts (GE1, GE2). One of the two subtransmissions (TG1, TG2) includes at least the first planetary gear set (PG1) while the other of the two subtransmissions (TG1, TG2) includes at least the second planetary gear set (PG2). The shafts (AB, AW, GE1, GE2, HW) are or can be operatively connected to the three planetary gear sets such that at least seven forward gears can be shifted to by the two subtransmissions (TG1, TG2). One of these gears can be shifted as a direct gear or another as an overdrive gear.
