Abstract:
A power-split gear, consisting of an adjustable hydrostatic unit (5), of a five-shaft summing gear (9) with a first (21), a second (22) and a third (23) output shaft, and of a range gear, the range shifts being carried out by the shifting of clutches, whereina) the range gear (25, 26) consists of a first planetary stage (25) contiguous with the summing gear (9), and of a second planetary stage (26) b) the first planetary stage (25) has a sunwheel (27), a ringwheel (29) and a web (31) with first planet wheels (32), the sunwheel (27) being drive-connected directly to the first output shaft (21) and the ringwheel (29) being connectable to the casing (36) by means of a first clutch (34), c) the second planetary stage (26) has a sunwheel (28), a ringwheel (30) and a web (31) with second planet wheels (33), the sunwheel (28) being drive-connected directly to the second output shaft (22) and the ringwheel (30) being connectable to the casing (36) by means of a second clutch (35), d) the third output shaft (23) is connectable to a power take-off shaft (40) by means of a third clutch (41), e) the web (31) is common to the two planetary stages (25, 26) and is permanently connected fixedly to the power take-off shaft (40), and f) the second output shaft (22) is connectable to the power take-off shaft (40) via a fourth clutch (42).
