A hybrid planetary gear transmission includes first, second and third planetary gear sets with respective sun, ring and planetary gears, the three planetary gear sets being arranged at a distance from each other concentrically to a common transmission axis, a transmission input shaft for receiving drive power from at least one drive machine, and a transmission output shaft for outputting drive power to a drive train. The hybrid transmission further includes a first coupling system for selectively connecting the transmission input shaft to the sun gear of the first planetary gear set, a second coupling device for selectively connecting the transmission input shaft to the planetary gear carrier of the first planetary gear set, and a connection between the ring gear of the third planetary gear set to the planetary carrier of the second planetary gear set. A sun gear of additional planetary gear set is rotationally mounted with respect to the transmission housing, and a planetary gear carrier of the additional planetary gear set may be connected to a first drive machine and a ring gear of the additional planetary gear set may be connected to a second drive machine, such that drive power can be transferred from the planetary gear carrier of the additional planetary gear set to the transmission input shaft.
