Gearbox with hydrostatic motors particularly for earth-movers

摘要

Gearbox with hydrostatic motors particularly for earth-movers, including a first hydrostatic motor and a second hydrostatic motor, each of which is connected respectively to a first countershaft and to a second countershaft by virtue of respective first and second transmission elements. The first countershaft and the second countershaft respectively support a plurality of input gearwheels which can be selectively coupled to a respective countershaft by virtue of selection elements. The input gearwheels mesh with respective secondary gearwheels so as to define gear ratios. The secondary gearwheels are supported by a secondary shaft to which they can be selectively coupled by virtue of the selection elements. A first output gearwheel is keyed on the secondary shaft and meshes with a second output gearwheel which is keyed on an output shaft.
