Abstract: A transmission having a plurality of tilting balls and opposing input and output discs provides an infinite number of speed combinations over its transmission ratio range. The transmission provides multiple powerpaths and can be combined with electrical components to provide motor/generator functionality, which reduces the overall size and complexity of the motor and transmission compared to when they are constructed separately. In one embodiment, rotatable components of a continuously variable transmission are coupled separately to an electrical rotor and to an electrical stator so that the rotor and stator rotate simultaneously in opposite directions relative to one another. In other embodiments, an electrical rotor is configured to transfer torque to or from a disc that is in contact with a plurality of speed adjusters, while an electrical stator is configured to transfer torque to a shaft that is operationally coupled to the speed adjusters via an idler.

Abstract: A continuously variable transmission is disclosed for use in rotationally or linearly powered machines and vehicles. The single axle transmission provides a simple manual shifting method for the user. An additional embodiment is disclosed which shifts automatically dependent upon the rotational speed of the wheel. Further, the practical commercialization of traction roller transmissions requires improvements in the reliability, ease of shifting, function and simplicity of the transmission. The disclosed transmission may be used in vehicles such as automobiles, motorcycles, and bicycles. The transmission may, for example, be driven by a power transfer mechanism such as a sprocket, gear, pulley or lever, optionally driving a one way clutch attached at one end of the main shaft.

Abstract: A variable speed transmission having a plurality of tilting balls and opposing input and output discs is illustrated and described that provides an infinite number of speed combinations over its transmission ratio range. The use of a planetary gear set allows minimum speeds to be in reverse and the unique geometry of the transmission allows all of the power paths to be coaxial, thereby reducing overall size and complexity of the transmission in comparison to transmissions achieving similar transmission ratio ranges.

Abstract: A continuously variable transmission (CVT) having a number of tiltable ball-leg assemblies configured angularly about a longitudinal axis. Each ball-leg assembly is in contact with, and guided through a tilting motion by an axially translating shift cam having a convex shape. The convex shape of the shift cam can have a profile defined by a set of parametric equations. In one embodiment, the profile of the shift cam vary according to the location of the contact point between an idler and the ball-leg assembly as well as the amount of relative axial motion between the ball-leg assembly and the idler. In some embodiments, the profile of the shift cam can be configured to control the axial translation of the idler relative to the change in tilt angle of the ball-leg assembly. In other embodiments, a roll-slide factor can be used to characterize the axial translation of the idler relative to the tilt angle of the ball-leg assembly.
