ABSTRACT:
Rotational power distribution and control systems and components thereof along with related methods are disclosed. The rotational power distribution and control system may, for example, be operable to function similarly to a typical automotive manual clutch. Other embodiments of the rotational power distribution and control system may function as continuously or infinitely variable transmissions. Still further embodiments of the rotational power distribution and control system may function as hybrid drive systems for various types of vehicles, including automobiles, trucks and busses. The rotational power distribution and control system includes at least one hydrostatic pump/motor and a rotational power dividing apparatus.
