Continuously variable transmission with differential controlling assemblies

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;
• 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, the torque feedback control assembly 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;
• 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 differential assembly configured and arranged to set the input to output speed ratio of the input/output planetary 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.

• a first cam spider, the first cam spider operationally connected to the input/output ratio output shaft, at least a portion of the first cam spider received in the at least one first track of the cam, the first cam spider transmitting torque to the cam via the at least a portion of the first cam spider in the at least one first track;
• and
• a second cam spider, the second cam spider operationally connected to an output shaft of the output assembly, at least a portion of the second cam spider received in the at least one second track, wherein the second cam spider rotates relative to the first spider which operates in the at least one first track causing a phase change between first and second spiders when a change in axial position of the torque feedback control assembly occurs.
