Disclosed is a planetary gear train ( 8 ) comprising an internal gear ( 24 ), a sun gear ( 52 ), a planet carrier ( 10 ) which is provided with planet shafts ( 18 ) and on which at least one planetary gear ( 20 ) is mounted, and a shifting device with a sliding sleeve ( 66 ). Said shifting device allows for a direct connection between a shaft ( 44 ) driving the planetary gear train ( 8 ) and an output shaft ( 12 ) of the planetary gear train ( 8 ) in one shifting position while making it possible to modify the rotational speed between the driving shaft ( 44 ) and the output shaft ( 12 ) of the planetary gear train ( 8 ) in another shifting position. The planet shaft ( 18 ) is disposed inside the planet carrier ( 10 ) so as to be rotatable within a bearing ( 22, 80 ). |
