Abstract
A transmission () includes a first input shaft () for a first prime mover (), a second input shaft () for a second prime mover (), as well as a first output shaft () and a second output shaft (), which are each coupleable to a drive output (). A first sub-transmission () includes the first input shaft (), and fixed gears () are arranged on the first input shaft (). Each of these fixed gears () meshes with a respective idler gear () on the first output shaft () and with a respective idler gear () on the second output shaft (). Shift elements (A, B, C, D) are associated with the output shafts (), depending on which the idler gears of the output shafts are coupleable to the particular output shaft in a rotationally fixed manner. A second sub-transmission () includes the second input shaft () and is designed as a planetary transmission. A ring gear () forms the second input shaft (). A carrier () is coupled to one of the output shafts (). Shift elements (F, E) are associated with the planetary transmission, via which, depending on their shift position, the sun gear () is fixedly connectable to the housing or the planetary transmission is bringable into direct drive. The planetary transmission is arranged coaxially to the first input shaft (). The carrier () of the planetary transmission is permanently coupled to one of the output shafts via a spur gear stage.
