Abstract
An output mechanism for use in a transmission includes an output shaft, a sun gear assembly, a planetary assembly, an outer gear, and an output gear. The sun gear assembly includes: a sun gear around the output shaft and a sun gear sleeve extending from the sun gear. The planetary assembly includes: one or more planetary gears around and meshed with the sun gear; and a casing surrounding the sun gear, joined to the one or more planetary gears, and configured to rotate around the sun gear when the one or more planetary gears rotate around the sun gear. The outer gear has inner teeth meshed with the one or more planetary gears and outer teeth being configured to be selectively meshed with a first external gear. The output gear is rotatably locked to the sun gear sleeve and is configured to be selectively meshed with a second external gear.
