An electromagnetic selection device of a two-stage planetary gear set ( 1 ) having one input shaft ( 2 ) and one output shaft ( 3 ), one sun gear ( 8 ), one ring gear ( 11 ), one planet carrier ( 10 ) with planetary gears ( 9 ), one transmission housing ( 6 ) and one sliding sleeve ( 14 ) for switching one first gear in which the ring gear ( 11 ) can be coupled with the housing ( 6 ) and one second gear in which the ring gear ( 11 ) can be coupled with the sun gear ( 8 ), the sliding sleeve ( 14 ) being movable by way of one electromagnet consisting of magnet coils ( 22, 23 ) and one armature ( 24 ). It is proposed that the armature ( 24 ) be situated rotatably, but axially fixed, upon the sliding sleeve ( 14 ). |
