Claims
- 1. A variable speed maximal torque transmission comprising:
a planetary gear set comprising a peripheral ring gear enmeshing a plurality of planet gears and a sun gear in mechanical communication with said plurality of planet gears; a carrier in mechanical communication with said planetary gear set; a motor in mechanical drive communication with said sun gear; and an auxiliary motor driving said peripheral ring gear.
- 2. The transmission of claim 1 wherein said carrier enmeshes said plurality of planet gears.
- 3. The transmission of claim 1 wherein said ring gear rotates at constant speed.
- 4. The transmission of claim 1 wherein said plurality of planet gears is three planet gears.
- 5. The transmission of claim 1 wherein said carrier is an output from the transmission.
- 6. The transmission of claim 1 wherein said carrier is coupled to a drive wheel of a vehicle.
- 7. The transmission of claim 1 wherein said auxiliary motor imparts power to said peripheral ring gear to satisfy the relationship
- 8. A process for operating a transmission comprising:
turning a planetary gear set with an auxiliary motor through a mechanical engagement of a toothed ring gear encompassing a set of planet gears where said set of planet gears simultaneously engages a toothed sun gear; and driving a carrier mechanically engaging said planetary gear set.
- 9. The process of claim 8 wherein said planetary gear set is turned at a variable speed.
- 10. The process of claim 8 wherein said carrier is a transmission output operative to power a drive wheel of a vehicle.
- 11. The process of claim 8 wherein turning said planetary gear set induces a torque on said carrier by way of a torque on said sun gear that satisfies the equation
