Abstract: A transmission arrangement for a hybrid vehicle, in which a connection for an internal combustion engine, a connection for an electric machine, and a transmission part are arranged in a manner able to be coupled to each other. The transmission part comprises a simple Ravigneaux planetary gear set with two planetary gears (PG1, PG2) and a single ring gear. The ring gear is coupled to a spur and bevel gear transmission (KT), which forms a power takeoff of the transmission arrangement. The transmission part furthermore comprises two brakes (B1, B2) and two clutches (K1, K2) as force-locking shifting elements.
