Abstract
An infinitely variable transmission is provided. The transmission includes an input assembly that is coupled to receive input rotational motion and an output assembly that is rotationally coupled to a load. An input/output planetary ratio assembly sets an input to output speed ratio. The input/output planetary ratio assembly has a first stator and a second stator. An input speed feedback control assembly is operationally attached to the input assembly. The input speed feedback control assembly includes a spider that is coupled to one of the first stator and the second stator. A movable member is operationally engaged with the spider with at least one shift weight. The moveable member is further operationally coupled to the other of the first stator and second stator. Moreover a torque feedback control assembly applies an axial load force in response to a torque of a load to the input speed control assembly.
