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.
Claims6
In a power divider gearbox having an input shaft and an output shaft and including a planetary differential gear drive comprising dual planetary pinions, two sun gears having different diameters and an internal ring gear meshing with said pinions, said planetary differential gear drive dividing the power transmitted to the power divider gearbox through the input shaft into a mechanical branch and a hydraulic branch, said hydraulic branch being connected to the internal ring gear;
- the improvement comprising:
- a first of said sun gears having a large diameter and being torsionally rigidly connected with the gearbox output shaft, and the second of said sun gears having a small diameter and being connected to the gearbox input shaft.
