CONTINUOUSLY VARIABLE TRANSMISSION |
摘要 |
Inventive embodiments are directed to components, subassemblies, systems, and/or methods for continuously variable transmissions (CVT). In one embodiment, a control system is adapted to facilitate a change in the ratio of a CVT. In another embodiment, a control system includes a stator plate configured to have a plurality of radially offset slots. Various inventive 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. Among other things, shift control interfaces for a CVT are disclosed. |

1. A continuously variable transmission (CVT) comprising:
a plurality of traction planet assemblies arranged angularly about a main shaft defining a longitudinal axis of the CVT; a first stator coupled to each traction planet assembly of the plurality of traction planet assemblies, the first stator configured to guide the traction planet assemblies; a second stator coupled to each of the plurality of traction planet assemblies; and a stator driver assembly coupled to the first stator. |
