Dual drive continuously variable transmission

摘要

A continuously variable transmission has a first shaft supporting two first pulleys. The two first pulleys each comprise a fixed disk portion and a moveable disk portion whereby axial movement of the moveable disk portions along the first shaft relative to the fixed disk portions changes an effective diameter of the two first pulleys. An articulating mechanism connects the moveable disk portions. The articulating mechanism has a body that is connected to the moveable disk portions. A second shaft extends generally parallel to the first shaft. Two second pulleys are journaled about the second shaft. The two second pulleys each has a fixed disk portion and a moveable disk portion. The two fixed disk portions are rotationally connected to the second shaft through a differential. A pair of belts connect the two second pulleys to the two first pulleys
