Abstract

A transmission arrangement for a hybrid vehicle includes an electric machine having a stator and a rotor. An electric-motor input shaft is connected to the rotor. A Ravigneaux gear set has a carrier, a set of long planets, a set of short planets, a ring gear, a first sun, and a second sun. The short planets mesh with the long planets. The ring gear meshes with the short planets and is connected to an output shaft. The first sun meshes with the short planets and is connected to the electric-motor input shaft. The second sun meshes with the long planets. The carrier is fixable on a transmission housing by a brake. The carrier, the second sun and an internal-combustion-engine input shaft are selectively couplable to one another in a torque-transmitting manner by a shiftable clutch arrangement. A hybrid vehicle and a drive train for a hybrid vehicle are also provided.
