A two-step multi-step transmission in which a first planetary gear set (1) has two radially nested transmission sub-assemblies. The first planetary gearset has an inner sun gear (11), inner planetary gears (12), an outer sun gear (14) which is rotationally fixed to the inner ring gear (13), outer planetary gears (15), an outer ring gear (16), and a carrier (17) on which the inner planetary gears (12) and the outer planetary gears (15) are mounted. The inner ring gear (13) and the outer sun gear (14), respectively, are rotationally fixed to a second, traditionally designed planetary gear set (2) and can be locked via a brake (42). |
