Abstract
A continuously variable transmission that includes an input assembly, an output assembly, an input/output planetary ratio assembly and a torque feedback control is provided. The input assembly is coupled to receive input rotational motion. The output assembly is rotationally coupled to a load. The input/output planetary ratio assembly sets an input to output speed ratio. The input/output ratio assembly has a first portion that is in rotational communication with the input assembly and a second portion that is in rotational communication with the output assembly. The torque feedback control assembly provides an axial load force in response to a torque of a load coupled to the output assembly. A differential assembly sets the input to output speed ratio of the input/output planetary ratio assembly based at least in part on an axial load force of the torque feedback control assembly.
