Components, subassemblies, systems, and/or methods for continuously variable transmissions (CVT) having a control system adapted to facilitate a change in the ratio of a CVT are described. In one embodiment, a control system includes a stator plate configured to have a plurality of radially offset slots. Various traction planet assemblies and stator plates can be used to facilitate shifting the ratio of a CVT. In some embodiments, the traction planet assemblies include planet axles configured to cooperate with the stator plate. In one embodiment, the stator plate is configured to rotate and apply a skew condition to each of the planet axles. In some embodiments, a stator driver is operably coupled to the stator plate. Embodiments of a traction sun are adapted to cooperate with other components of the CVT to support operation and/or functionality of the CVT.
A continuously variable transmission (CVT) comprising a main shaft defining a main drive axis and a plurality of spherical traction planets arranged around the main drive axis, each traction planet comprising a planet axle defining a tiltable axis of rotation, the CVT comprising:
A method of controlling a continuously variable transmission (CVT) comprising a main shaft defining a main drive axis and a plurality of spherical traction planets arranged around the main drive axis, each traction planet comprising a planet axle defining a tiltable axis of rotation, a first end of each planet axle being positioned in a radially offset slot in a first stator, mounted coaxially about the main axis, and a second end of each planet axle being positioned in a radial slot in a second stator, mounted coaxially about the main axis, the method comprising:
