Abstract: A compact transmission, in particular for use within a single-wheel drive unit, includes a gear carrier fixed to the frame, which has a continuous central recess, and a main transmission having an internally toothed ring gear rotatably mounted on the outside of the gear carrier, externally toothed gears arranged in front of the one of the end faces of the gear carrier and meshing with the ring gear, and an input sun shaft. The compact transmission further includes a transmission pre-stage arranged within the central recess, and a pre-stage input shaft having an externally toothed pre-stage sun wheel, a pre-stage ring gear, and at least one pre-stage intermediate gear meshing with both the pre-stage sun wheel and with the pre-stage ring gear. An additional carrier is fastened to the transmission carrier, via which the pre-stage intermediate gears are held captively in the central recess.

Abstract: A power split gearbox, in particular for a motor vehicle, includes a mechanical power branch and a hydrostatic power branch. The mechanical power branch and hydrostatic power branch, in a parallel arrangement with respect to one another, are in contact with a common drive shaft. The branched power from the mechanical power branch and hydrostatic power branch are combined in a gear drive arranged on an end side. The mechanical power branch has two planetary gear sets with sun gears, planet gears and internal gears. A clutch is arranged on a side of one of the two planetary gear sets. An internal gear is connected to a sun gear shaft by the clutch.
