An automatic stepless transmission includes a driving shaft, a driving disk rotatable by the driving shaft, and a clutch assembly rotatable by the driving disk. Two parallel guiding slots are provided on the driving shaft. An eccentric plate with a notch is sleeved onto the driving shaft. A compressible resilient regulation mechanism is disposed between the notch and the driving shaft. The driving disk is installed on the eccentric plate via a bearing. The eccentric plate offsets in relation to the axis of the driving shaft, and at the same time the eccentric plate drives the driving disk offset. The automatic stepless transmission can compress or release the resilient regulation mechanism according to loads. The eccentricity between the eccentric plate and the driving shaft can therefore be adjusted, and the eccentric plate can drive the driving disk to move. Thus, the eccentricity of the driving disk can be regulated without manual work. The transmission has a simple structure and can be operated easily. It can adjust the transmission ratio automatically. Therefore the cost and the failure rate can be reduced efficiently. |
