摘要

An infinitely variable hydrostatic transmission drive for self-propelled machines having a plurality of transmission motors which are fed from a common displaceable transmission-drive pump, at least one variable displacement motor having a swashplate which can be swung back into a zero position and at least one fixed displacement motor are provided in hydraulic parallel circuit. The motors operate in at least one case via a common back gearing on a common output, a shift coupling being provided between the variable displacement motor and an output.
