摘要：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.
