Claim 10:
11. A planetary transmission, comprising:
a differential;
a set of planetary gears;
a common planetary carrier for the differential and the set of planetary gears;
a set of planet journals;
the differential has a set of first differential gears, a set of second differential gears, a first sun gear and a second sun gear, the first differential gears are each in mesh with the first sun gear in a first toothing plane and the second differential gears are each in mesh with the second sun gear in a second toothing plane, and one of the first differential gears is in mesh with at least one of the second differential gears;
the first and second toothing planes are radial planes that extend perpendicular to a central axis and centrally intersect respectively a meshing area of the first differential gears with the first sun gear and a meshing area of the second differential gears with the second sun gear;
the planetary carrier comprises a first carrier web, a second carrier web, and an intermediate web formed axially between the first and second carrier webs, wherein the set of second differential gears extend axially through the intermediate web; and
one planetary gear of the set of planetary gears and one first differential gear of the set of first differential gears are located on a same one of the planet journals, axially separated from one another by the intermediate web;
wherein the planet journals each have first and second journal steps in a diameter thereof, the first journal step is larger in diameter than the second journal step, and the first differential gears are each seated on the first journal step and the planetary gears are each seated on the second journal step, and wherein each of the planet journals have at least one fastening at an end of the planet journal to secure the planet journal to the planetary carrier.
