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.
