Abstract:
A gear train for coupling first and second rotational inputs to a rotational output, comprising:a sun gear rotatable about a center axis;a ring gear independently rotatable about the center axis;one or more first planetary gears, each meshingly engaged with the sun gear;one or more second planetary gears meshingly engaged with the ring gear and with one of the first planetary gears; anda carrier rotatable about the center axis and supporting the first and second planetary gears for rotation about their respective axes,whereby the first rotational input is selectively coupled to one of the sun gear, carrier and ring gear, the second rotational input is selectively coupled to a different one of the sun gear, carrier and ring gear, and the rotational output is selectively coupled to the remaining one of the sun gear, carrier and ring gear.
