Abstract
A continuously variable transmission is provided. The continuously variable transmission includes an input assembly, an output assembly, an input/output planetary ratio assembly and a torque feedback assembly. The input/output planetary ratio assembly is configured and arranged to set 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. Moreover, the torque feedback control assembly is coupled to provide torque feedback to the input/output planetary ratio assembly to at least in part control the input to output speed ratio of the input/output planetary ratio assembly.
