摘要: A transmission for automatically changing a gear ratio into three forward gear ratios and one reverse gear ratio which has three planetary sun gears mounted on an input shaft (main shaft), each having different numbers of teeth, planetary pinion groups mounted on said planetary pinion pins (sub shafts) and engaged with the planetary sun gears, respectively, so as to rotate around respective planetary pinion pins, planetary carriers supporting planetary pinion pins and enabling the planetary pinion groups to rotate around an axis of the planetary sun gears, and forward and reverse locking means, wherein the input shaft is connected to a planetary low sun gear while the planetary carriers are locked by the forward locking means to obtain a normal first reduction speed; in the same state as the planetary carriers remain locked, the input shaft is connected to a planetary second sun gear to obtain a normal second reduction speed; by allowing the planetary carriers to rotate, the input shaft is connected to a planetary output sun gear which is connected to an output shaft to obtain the final normal directcoupling drive; and the input shaft is connected to the planetary low sun gear, at the same time, the planetary second sun gear is locked by the reverse locking means to obtain the reverse reduction speed.
