Abstract
A multi-speed drive for a supercharger includes a planetary gear mechanism with a sun gear mechanism, a plurality of planet gears mounted on a planet carrier, and a ring gear, all mounted for rotation on a stationary shaft. A rotary-mechanical drive input is received by either the ring gear or the planetary drive, and a rotary-mechanical drive output is provided by the planetary drive when the ring gear receives the input, or by the ring gear when the planetary drive receives the input. A one-way roller clutch is disposed coaxially with the planetary gear mechanism, between the sun gear mechanism and the stationary shaft. A hydraulically-actuated, clutch assembly mounted coaxially with the planetary gear mechanism on the stationary shaft engages the sun gear and the ring gear to change the gear ratio of the drive.
