Abstract:
1. A continuously variable transmission comprising: an input assembly configured to be coupled to receive input rotational motion; an output assembly to provide a rotational output, the output assembly configured to be rotationally coupled to a load; an input/output planetary ratio assembly configured and arranged to set an input to output speed ratio between the input assembly and the output assembly; an input speed feedback control assembly configured and arranged to provide an axial speed force in response to a rotation from the input assembly on a shift rod; a torque feedback control assembly configured and arranged to provide an axial load force on the shift rod in an opposite direction from the axial speed force in response to a torque of a load coupled to the output assembly; and a shifting member coupled to the shift rod, the shifting member further configured and arranged to control the input/output planetary ratio assembly based on a position of the shift rod.
