摘要： A power transfer device includes a casing, a lubricant reservoir in the casing having lubricant therein, and a shaft rotatably supported in the casing. The shaft extends into the lubricant reservoir. A lubricant driving structure is coupled to the shaft for common rotation. The lubricant driving structure includes at least one helically shaped member that extends longitudinally along and circumferentially about the shaft. The at least one helically shaped member is located in the lubricant reservoir. Rotation of the at least one helically shaped member drives the lubricant axially along the shaft and away from the lubricant reservoir. According to other features, an oil propeller wheel is mounted around a shaft in the power transfer device for rotation therewith. The oil propeller wheel communicates with the lubrication in the lubricant reservoir and is operable to direct the lubricant from the lubricant reservoir axially along the shaft toward the differential assembly.

摘要： The two-speed transmission (10) for driving an alternator or other engine accessory includes an enclosed gear case (12). An output shaft (28) passes through both ends of the gear case. Bearings (30, 32) supported on the gear case support the ends of the output shaft. A tubular input shaft (64) surrounds the output shaft and is journaled on the output shaft between the two output shaft support bearings. A planet gear carrier (86) is rotatably journaled on the output shaft inside the gear case. Compound planet gears (112) are rotatably supported by the planet gear carrier (86) with one planet (116) of each compound planet gear in mesh with a sun gear (84) on the tubular input shaft (64) and with a planet (118) of each compound planet gear in mesh with a sun gear (94) on the output shaft (28). A brake assembly (124, 136 and 142) is either applied to lock the planet gear carrier (86) to the gear case or is released to let the planet carrier rotate in the gear case. When the tubular input shaft (64) is driven and the brake assembly holds the planet carrier (86), torque is transmitted from the input shaft to the input sun gear (84) to the first planet gear (116) to the second planet gear (118) to the output sun gear (94) and to the output shaft (28). When the brake assembly is released, torque passes from the tubular input shaft (64) directly to the output shaft (28) through a one-way clutch (67) and the input and output shafts run at the same speed. A lubrication system lubricates critical bearings in the transmission.
