1. A planetary transmission, comprising:
a differential (3);
at least one set of planetary gears (6);
a common planetary carrier (9) for the differential (3) and the set of planetary gears (7);
at least one set of planet journals (18);
the differential (3) has a set of first differential gears (11), a set of second differential gears (16), a first sun gear (12) and a second sun gear (13), the first differential gears (11) are each in mesh with the first sun gear (12) in a first toothing plane (I) and the second differential gears (16) are each in mesh with the second sun gear (13) in a second toothing plane (II), and one of the first differential gears (11) is in mesh with at least one of the second differential gears (16);
each of the first and second toothing planes is a radial plane which is perpendicular to a central axis and centrally intersects respectively the meshing of the first differential gears (11) with the first sun gear (12) or the meshing of the second differential gears (16) with the second sun gear (13);
a further set of the planetary gears are in mesh with at least one further gear in a third toothing plane, wherein the second toothing plane is positioned axially between the first toothing plane and the third toothing plane;
the planetary carrier (9) comprises a first carrier web (10), a second carrier web (21) and an intermediate web (20) formed axially between the first and second carrier webs, wherein the set of second differential gears extend axially through the intermediate web; and
in each case one planetary gear (7) of the set of planetary gears (7) and one first differential gear (11) of the first set of differential gears (11) is seated to follow one another axially on one planet journal (18) of the at least one set of planet journals and are axially separated from one another by the intermediate web (20), and the intermediate web (20) extends in radial directions running axially between the first toothing plane (I) and the second toothing plane (II).
