proposed is a planetary transmission comprising an internal gear , a sun gear and a planet carrier , upon which at least one planet gear is supported . the planetary transmission possesses a clutch apparatus with a sliding sleeve , which in a first shift - position enables a direct connection between one of the shafts driving the planetary transmission and an output shaft of the planetary transmission . in a second shift - position , the connection of the sliding sleeve enables a change in the speed of rotation between the driving shaft and the output shaft of the planetary transmission . the planet gear is so supported on the planet carrier , that in case of a shifting from a one shift - position into a respective other shift - position , the planet gear on the planet carrier becomes axially slidable .
