Abstract
Proposed is a planetary transmission (8) comprising an internal gear (24), a sun gear (52) and a planet carrier (10), upon which at least one planet gear (20) is supported. The planetary transmission (8) possesses a clutch apparatus with a sliding sleeve (66), which in a first shift-position enables a direct connection between one of the shafts (44) driving the planetary transmission (8) and an output shaft (12) of the planetary transmission (8). In a second shift-position, the connection of the sliding sleeve (66) enables a change in the speed of rotation between the driving shaft (44) and the output shaft (12) of the planetary transmission (8). The planet gear (20) is so supported on the planet carrier (10), that in case of a shifting from a one shift-position into a respective other shift-position, the planet gear (20) on the planet carrier (20) becomes axially slidable.
