A compound planetary gear unit comprising a first planetary gear set, a second planetary gear set, a planet carrier for both planetary gear sets together, a first sun gear and a second sun gear as well as comprising a first ring gear and a second ring gear, wherein the first planetary gear set is formed by first planetary gears, which are carried by the planet carrier at a radial distance from a central axis of the compound planetary gear unit in such a way that each of said first planetary gears can be rotated about its own first axis of rotation. |

1. A compound planetary gear unit (1) comprising a first planetary gear set, a second planetary gear set, a planet carrier (4) for both planetary gear sets together, a first sun gear (8) and a second sun gear (11) as well as comprising a first ring gear (5) and a second ring gear (6), wherein the first planetary gear set comprises first planetary gears (9), which are carried by the planet carrier (4) at a radial distance from a central axis (24) of the compound planetary gear unit (1) in such a way that each of said first planetary gears can be rotated about its own first axis of rotation (18), and which are thereby in meshing engagement with the first sun gear (8) and the first ring gear (5), and wherein the second planetary gear set comprises second planetary gears (10, 16), which are carried by the planet carrier (4) at a radial distance from the central axis (24) in such a way that each of said second planetary gears can be rotated about an axis of rotation (18), and which are thereby in meshing engagement with the second sun gear (11) and the second ring gear (6), wherein the first sun gear (8) comprises a first gear tooth system (12) with a first number of teeth that is different from a second number of teeth of a second gear tooth system (19) of the second sun gear (11); and that the second planetary gear set comprises at least one planetary gear (10) with a third gear tooth system (17) with a third number of teeth, which is different from a fourth number of teeth of a fourth gear tooth system (18) of at least one of the second planetary gears (16). |
