Continuously variable transmission with input/output planetary ratio assembly

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, the input/output ratio assembly having 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 input/output planetary ratio assembly including a first stator, a second stator and a plurality of planets movably engaged between the first and second stator, the input output ration based on a rotation of the second stator and the first stator in relation to each other;
• a torque feedback control assembly configured and arranged to provide an axial load force in response to a torque of a load coupled to the output assembly;
• an input speed feedback control assembly configured and arranged to provide an axial force in response to a rotation from the input assembly;
• and
• a helical shift control assembly configured and arranged to set the input to output speed ratio of the input/output ratio assembly based on the balancing of the axial force of the input speed feedback control assembly force with the axial force of the torque feedback control assembly, the helical shift control assembly including a first track and second track system to control the rotation of the second stator in relation to the first stator of the input/output ratio assembly.
