Abstract
An automatic two-mode high reduction power transmission system. A power transmission system includes a first device that delivers a first input and receives a second output. A second device delivers a second input and receives a first output. A power transmission has two planetary gear sets and operates in a first mode at a first speed ratio, where the first input is received from the first device and in response, the first output is delivered to the second device. The power transmission operates in a second mode at a second speed ratio that is different than the first speed ratio, where the second input is received from the second device and in response, the second output is delivered to the first device. A pair of freewheel mechanisms automatically couple one of the first or second devices with the power transmission to provide the two modes.
