Abstract
Planetary gearsets (PS, PS) are coupled and arranged coaxially and radially offset relative to one another. Gearset (PS) is arranged radially inside gearset (PS) and each have a carrier on which planet gears () respectively rotate. A support ring, having inner and outer teeth, is radially arranged between the planet gears (). A sun gear, which meshes with planet gears () which mesh with the inner teeth of the support ring, is radially within gearset (PS). A ring gear, which meshes with planet gears () which mesh with inner teeth of the support ring, is radially outside gearset (PS). The sun gear of gearset (PS) is fixed to an input shaft. The carrier of gearset (PS) is fixed to the ring gear of gearset (PS) and mounted, via a radial-axial bearing, on the output shaft. The carrier of gearset (PS) is fixed to an output shaft.
