Abstract (en)

[origin: WO2014139743A1] The invention relates to a vehicle transmission comprising two transmission input shafts (GE1, GE2) and at least three planet gear sets (PG1, PG2, PG3), each transmission input shaft (GE1, GE2) being associated with a partial transmission (TG1, TG2). One of the two partial transmissions (TG1, TG2) comprises at least the first planet gear set (PG1) and the other partial transmission of the two partial transmissions (TG1, TG2) comprises at least the second planet gear set (PG2). The aim of the invention is to provide a vehicle transmission that can be cost-effectively produced and can be used both in conventional and hybrid powertrains. According to the invention, the transmission input shafts (GE1, GE2) are or can be operatively connected to the planet gear sets (PG1, PG2, PG3) such that the two partial transmissions (TG1, TG2) can be variably activated to provide a plurality of gear ratios, and one of the gears can be shifted as a direct gear.
