Abstract

A reduction drive has an electric motor and an output hub rotatable with respect to a motor housing. A planetary gear reduction assembly is disposed entirely within an internal volume formed by the output hub and includes a first ring gear fixed to and rotating with the output hub, a second ring gear fixed to a portion of the main housing, a sun gear driven by the motor shaft, and gears mounted on a carrier assembly and driven by the sun gear. Each planet gear has a first stage gear driving the first ring gear, and a second stage gear engaged to the second ring gear.
