Abstract
A load shift transmission with stepless hydrostatic gearing comprising: a hydrostatic transmission having a displacement machine with an adjustable volume and a displacement machine with a constant volume; a five-shaft planetary gear transmission having: a coupling shaft for the constant volume displacement machine, the coupling shaft formed by a first planet gear section which meshes with a first sun gear and a first ring gear; a start up coupling shaft formed by a second planet gear section which meshes with a second sun gear; a slow running coupling shaft formed by a third planet gear section which meshes with a third sun gear; a fast running coupling shaft formed by the ring gear of the first planet gear section; an input shaft formed by a planet gear carrier on which the first, second and third planet gear sections are mounted; and an output shaft, wherein the coupling shafts alternately transfer the requisite power through subsequent gear shifting steps to the output shaft.
