A planetary transmission (100) comprising an input member (13), an output member (19), a planetary gear assembly (13,14,15,16,17) mechanically disposed between the input member and the output member, a centrifugal clutch (40) mechanically disposed between the input member and the output member, a one-way clutch (22) mechanically disposed between the input member and the output member, the one-way clutch for directly coupling the input member and the output member from zero rotational speed up to a first rotational speed, the centrifugal clutch for directly coupling the input member and the output member from a second rotational speed greater than zero rotational speed to a third rotational speed which is in excess of the first rotational speed, and a brake member for selectively controlling rotation of the planetary gear assembly. |
