Abstract
A drive device includes a superposition transmission, a main drive machine connected to an input shaft of the transmission, auxiliary drives and an output shaft of the transmission connectable to a work machine. The transmission has a planetary transmission with an internal gear, sun gear, planet carrier and planet gears. The input shaft is connected to the internal gear, the output shaft is connected to the sun gear, and the auxiliary drives are connected by a first transmission stage with constant transmission ratio to the planet carrier. An auxiliary drive connection with constant transmission ratio is between the auxiliary drive and the internal gear or a pinion on the input shaft. A switchable clutch in the auxiliary drive connection can activate or interrupt the auxiliary drive connection, so that upon interruption, the connection between auxiliary drive and planet carrier remains activated by the clutch through the first transmission stage.
