Abstract:
Inventions are directed to components, subassemblies, systems, and/or methods for continuously variable transmissions (CVT). In one aspect, a control system is adapted to facilitate a change in the ratio of a CVT. A control system includes a control reference nut coupled to a feedback cam and operably coupled to a skew cam. In some cases, the skew cam is configured to interact with carrier plates of a CVT. Various inventive feedback cams and skew cams can be used to facilitate shifting the ratio of a CVT. In some transmissions described, the planet subassemblies include legs configured to cooperate with the carrier plates. In some cases, a neutralizer assembly is operably coupled to the carrier plates. A shift cam and a traction sun are adapted to cooperate with other components of the CVT to support operation and/or functionality of the CVT. Among other things, shift control interfaces for a CVT are described.
