An automatic stepless transmission including a high speed gear system and a distribution gear train. An input of the high speed gear system is distributed by the distribution gear train. A high speed counter gear train and a junction gear train are provided. An output of the high speed gear system is produced through the distribution gear train, the high speed counter gear train and the junction gear train. A low speed gear system, a spring type high and low adjustment gear train and a low speed outer counter gear train are provided. An auxiliary adjustment gear train is operatively connected to the low speed gear system. An inner counter gear train is operatively connected to the low speed gear system. An input of the low speed gear system is distributed by the distribution gear train and an output of the low speed gear system is produced through the distribution gear train the spring type high and low adjustment gear train and the junction gear train via the low speed outer counter gear train or the auxiliary adjustment gear train and the inner counter gear train. A neutral clutch train is operatively provided and a neutral gear train is operatively positioned at the output of the high and low speed gear systems. A main adjustment gear train is operatively connected to a sensitive adjustment gear train wherein the load on the output in the high and low speed gear systems is selectively regulated by the main adjustment gear train and auxiliary gear train depending on speed changes. |
