Abstract: A continuously variable transmission includes one or more cone shaped members which each have a cone shaft centrally positioned therethrough. The cone shaped member also includes a pair of fixed spiraled grooved shafts, including a first shaft therein with a respective spiral groove that spirals in a direction 180 degrees from the direction of each spiral groove in a second fixed spiral grooved shaft. A sliding alignment guide moves laterally within each cone shaped member. Moreover, the alignment guide has a first end interacting with a keyed sprocket, having engagement teeth and an internal nib. The alignment guide has a second end interacting with a second keyed sprocket, also having engagement teeth and an internal nib. A chain interlinks with the teeth of the keyed sprockets, and interlinks with an input driving sprocket, which causes the chain to rotate, so that the input driving sprocket and the chain drive each cone shaped member while lateral adjustments change the speed ratio from the input shaft to the output shaft of each cone shaped member.

Abstract: A variable torque transmission includes at least one disc-shaped gear 30 having a circular toothed surface 36 with flat beveled teeth 32 that mate along radius 38 with the cone-shaped teeth of pinion gear 10 to produce an infinitely variable lever arm and thus infinitely variable torque while allowing a constant rotation ratio between the drive shafts of the flat beveled gear 30 and pinion gear 10. The result is that the drive shaft energy input may be constant and thus energy efficiency may be maximized while torque may be selectively varied.

Abstract: A non-slip continuously variable transmission (CVT) uses the positive engagement of gear teeth and does not rely on friction to transmit torque. The transmission has a ring gear with spur gear teeth at its periphery and conical teeth at its top surface adjacent to an offset circular track. The circular track or channel guide is a slightly smaller diameter than the ring gear and is positioned within the ring gear. Short plates with worm gears pivoted on cantilever brackets are constrained to move within the circular path defined by the channel guide. Due to the offset from the ring gear, a plate traversing this path will engage the conical teeth of the ring gear over a short arc of travel as the worm gear enters and then leaves engagement. This ability to move the ring gear over an arc by passing a worm gear plate around the near region of the circular channel can be reversed in both direction and in principal by having the ring gear move the worm gear plate.

Abstract: A continuously variable transmission comprises a cone shaped member having a shaft centrally positioned therethrough and having a plurality of radially extending wings. The cone shaped member may be slidably moveable axially with respect to said drive shaft. A ring gear encircles the cone shaped member in interlocking communication. The ring gear may be enclosed by a housing and pivotable about a fixed point. A plurality of linkage arms may be pivotally connected to the radially extending wings and each said linkage arm is pivotally connected to a joining member. Each radially extending wing comprises a ledge portion for receiving a linkage arm, wherein each linkage arm comprises a slider member for slidably engaging the ledge. The transmission controls the sliding of the cone shaped member horizontally along the axis of the drive shaft, which results in a proportional angular displacement of the ring gear about the point of pivot.
