Abstract
A hybrid drive arrangement of a motor vehicle, which has a main transmission having an input shaft and housing. An electric machine, that can operate either as a motor and a generator, has a stator and rotor which, on the input side, is connected to the main transmission. A planetary gearset is arranged between the rotor and the transmission input shaft. The transmission input shaft has a central oil bore and transverse bores for supplying oil to the planetary gearset and the electric machine. The planetary gearset and the electric machine are accommodated in a hybrid housing. The hybrid housing is connected to the transmission housing of the main transmission by an oil return line. The oil stream passing into the oil return line is in heat-transferring connection, by way of a partition wall, with a coolant which flows through a cooling duct arranged radially outside the stator.
