<p>The invention relates to a multi-stage gearbox of planetary construction, in particular splitter gearbox of a working machine, with a housing (1) in which three planet sets (4, 5, 6; 20, 21, 6) and a plurality of shafts are accommodated, and with shift elements which are formed by at least one brake (7; 7, 16) and clutches (8, 9, 10; 8, 9, 10, 18; 8, 9, 10, 18, 24; 8, 9, 10, 18, 27), and by means of the specific actuation of which different transmission ratios can be produced between a drive shaft (2; 19) and an output shaft (3; 22; 26), wherein a third shaft (11) connects an internal gear of a first planet set (4; 20) to an internal gear of a second planet set (5; 21) and can be detachably coupled via a first clutch (8) to the output shaft (3; 22; 26), wherein a fourth shaft (12) is coupled to a sun gear of the first planet set (4; 20) and is firstly fixable to the housing (1) by means of a first brake (7) and is secondly connectable to a fifth shaft (13) via a second clutch (9), wherein, furthermore, said fifth shaft (13) is connected to a sun gear of the second planet set (5; 21) and can be coupled by means of a third clutch (10) to a sixth shaft (14; 17; 23) which is connected to a web of the first planet set (4; 20), and wherein the drive shaft (2; 19) is connected to a web of the second planet set (5; 21).</p> |
