Abstract
A planetary transmission comprising an input member, an output member, a planetary gear assembly mechanically disposed between the input member and the output member, a centrifugal clutch mechanically disposed between the input member and the output member, a one-way clutch 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.
