Title: MULTI-SPEED PLANETARY DRIVE FOR A SUPERCHARGER
Abstract:
A multi-speed drive (25) for a supercharger, comprising: a stationary shaft (30, 65, 165): a planetary gear mechanism with a sun gear assembly (83, 183) a plurality of planet gears (130, 230) mounted on a planet carrier (118, 218), and a ring gear (107, 207), 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 (87, 187) disposed coaxially with the planetary gear mechanism, between the sun gear mechanism and the stationary shaft; and, a hydraulically-actuated, clutch assembly (150/152, 250/252) 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.
