Abstract

The invention relates to a multi-speed planetary transmission (10). The multi-speed planetary transmission (10) comprises a driveshaft (12), which comprises a sun gear (18) and a ring gear (19), and an output shaft (14), which comprises a planet carrier with at least one planet gear (30). The drive shaft (12) and the output shaft (14) can be connected together or separated from each other by means of a clutch (20). The multi-speed planetary transmission (10) has a freewheel (26), via which a shift is carried out between a first transmission ratio i_1 and a second transmission ratio i_2 under a load using the clutch (20).
