Multi-Speed Planetary Drive For A Supercharger

摘要

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.

1. A multi-speed drive for a supercharger, comprising:
a stationary shaft: 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 the stationary shaft; a rotary-mechanical drive input being received by either the ring gear or the planet carrier, and a rotary-mechanical drive output being provided by the planet carrier when the ring gear receives the input, or by the ring gear when the planet carrier receives the input; a one-way roller clutch disposed coaxially with the planetary gear mechanism, between the sun gear mechanism and the stationary shaft; and, a hydraulically-actuated, clutch assembly mounted coaxially with the planetary gear mechanism on the stationary shaft, and operably engaging the sun gear and the ring gear to change a gear ratio of the multi-speed drive.
