Abstract

A power divider gearbox including a planetary differential gear drive, comprising dual planetary gears which mesh with two sun gears having different diameters and with an internal ring gear, wherein the planetary differential gear drive divides the incoming power input transmitted to the power divider gearbox through an input shaft into a mechanical branch and into a hydraulic branch (displacement machine) and in which the last-mentioned branch is connected to the internal ring gear of the planetary differential gear drive.
