    摘要： A planetary gear train of an automatic transmission provides at least eight forward speeds and one reverse speed by combination of: first to fourth planetary gear sets respectively having first to third rotational elements, fourth to sixth rotational elements, seventh to ninth rotational elements or tenth to twelfth rotational elements; two transfer gears and five control elements selectively connecting one shaft to another shaft selected from first to tenth shafts or to a transmission housing. In particular, an input shaft is mounted with the first, second and third planetary gear sets, an output shaft is mounted with the fourth planetary gear set, the eighth shaft is fixedly connected with the tenth rotational element and externally engaged with the sixth shaft via one of the two transfer gears; the tenth shaft is fixedly connected with the twelfth rotational element and externally engaged with the fourth shaft via the other transfer gear.

    摘要： A universal driving device includes a sun gear rotatably provided; a ring gear disposed on a rotation plane coplanar to a rotation plane of the sun gear and provided so that a rotation shaft of the ring gear is movable relative to a rotation shaft of the sun gear; and a gear train engaging the sun gear to the ring gear and configured to allow a relative motion between the rotation shaft of the sun gear and the rotation shaft of the ring gear and define a continuous power transmission state between the sun gear and the ring gear.
