GETRIEBE MIT HYDROSTATISCHEN MOTOREN, INSBESONDERE FÜR ERDBEWEGUNGSMASCHINEN.

摘要

Gearbox with hydrostatic motors particularly for earth-movers, including a first hydrostatic motor (1) and a second hydrostatic motor (2), each of which is connected respectively to a first countershaft (5) and to a second countershaft (8) by virtue of respective first (6-7) and second (9-10) transmission means. The first countershaft (5) and the second countershaft (8) respectively support a plurality of input gearwheels (11-14) which can be selectively coupled to a respective countershaft by virtue of selection means (15). The input gearwheels (11-14) mesh with respective secondary gearwheels (16-18) so as to define gear ratios. The secondary gearwheels (16-18) are supported by a secondary shaft (19) to which they can be selectively coupled by virtue of the selection means (15). A first output gearwheel (20) is keyed on the secondary shaft (19) and meshes with a second output gearwheel (21) which is keyed on an output shaft (22).
