摘要： An infinitely variable transmission, in which the driver and driven members can exchange their roles—with the driver becoming the driven, and vice versa. The initially chosen driver carries within it a number of movable parts, which the driving forces bring into contact with the driven member, in a manner designed to produce a momentary lock between the driver and driven members, at the point of the torque transfer between them. In one embodiment the driven member—which can be a flat disc—is clamped between two oppositely placed drivers. Infinite variability is achieved by controllably relocating the fixed diameter drivers to smaller or larger diameter points on the so clamped disc. The output can be harvested from the rotation of said driven disc directly. Or one or more driver members like these which are used to rotate said disc, can be brought into contact with different locations on said disc, and become driven by it. In such a case a number of different speeds, or torque levels, can be taken simultaneously as outputs from a single rpm/torque input. In embodiments with a single driver of convex shape input, the preferred driven member is a cone with a concave curvature, to allow for a larger contact zone than two opposing convex parts could provide. Either the flat clamped disc version, or the cone versions, can be stacked vertically or horizontally, with cones nested within each other, to multiply gear ratios and or torques as wished.
