Abstract

PURPOSE: To improve the operational characteristic of speed changes in forward and reverse rotations, by transmitting the power from a driven shaft to planetary gears through three-shaft gear trains.
CONSTITUTION: A gear train 40 interposed between a driven shaft 13 and the second element 32 of planetary gears 30 is formed into two sets of three-shaft gear trains variable speed shiftable into two stages in forward and reverse rotatios, and through each of the three-shaft gear trains 40 the power is selectively transmitted from the driven shaft 13 to the second element 32 of the planetary gears 30. In this way, fully within a prescribed range of the rotational speed ratio, the speed change ratio in a forward or reverse rotation can be continuously changed, and the operational characteristic can be improved when performed the change-over between forward and reverse rotations.
