Abstract:
A continuously variable ratio power transmission having a source of power connected to an input shaft comprising:a power divider unit having a planetary gear set operatively driven by the input shaft and having a power divider planetary gear set carrier engaging the planetary gear set, a power divider annular ring gear engaging and surrounding the power divider planetary gear set, the power divider carrier being connected to an output shaft;a power combiner unit having a planetary gear set operatively driven by an input shaft which is operatively connected to the output shaft of the power divider unit, the power combiner unit including a power combiner planetary gear set carrier and a power combiner annular ring gear engaging and surrounding the power combiner planetary gear set, the power combiner carrier being operatively connected to a transmission output shaft;a hydraulic power diverting motion means connected to the power divider output shaft to selectively apply resistance to the rotation of the power divider output shaft; anda high speed connecting gear set operatively connecting the power divider annular ring gear to the power combiner annular ring gear to selectively transfer high speed power from the power divider unit to the output shaft of the power combiner unit.
