Abstract
A power-split gear consists of an adjustable hydrostatic unit ( ), of a five-shaft summing gear ( ) with a first, second and third output shaft, and of a range gear. So that the gear can be manufactured and controlled more easily, the range gear consists of a directly contiguous first ( ) and second ( ) planetary stage; the first planetary stage ( ) has a sunwheel ( ), a ringwheel ( ) and a web ( ), the sunwheel ( ) being drive-connected directly to the first output shaft ( ) and the ringwheel ( ) being connectable to the casing ( ) by means of a first clutch ( ); the second planetary stage ( ) has a sunwheel ( ), a ringwheel ( ) and a web ( ), the sunwheel ( ) being drive-connected directly to the second output shaft ( ) and the ringwheel ( ) being connectable to the casing ( ) by means of a second clutch ( ); the third output shaft ( ) is connectable to a power take-off shaft ( ) by means of a third clutch ( ); the webs ( ) of the two planetary stages are permanently connected fixedly to one another and to the power take-off shaft ( ), and the second output shaft ( ) is connectable to the power take-off shaft ( ) via a fourth clutch ( ).
