MULTI-SPEED AUTOMATIC TRANSMISSION

摘要

A power transmission includes an input, output, a planetary gearset including a first sun gear, a first ring gear, a first carrier driveably connected to the input, first pinions supported on the first carrier and meshing with the first sun gear, and second pinions supported on the first carrier and meshing with the first ring gear and first pinions, and a second planetary gearset including a second sun gear, a third sun gear, a second ring gear driveably connected to the output, a second carrier, third pinions supported on the second carrier and meshing with the second sun gear and second ring gear, and fourth pinions supported on the second carrier and meshing with the third sun gear and the third pinions.
