Abstract
A planetary gear system has a first planetary gear set including a first ring gear, a first sun gear and a first planet carrier, and a second planetary gear set including a second ring gear, a second sun gear and a second planet carrier. The first and second carriers are integrated into a common carrier, and at least one long pinion is provided between the first and second planetary gear sets so as to form a third equivalent planetary gear set with the first and second ring gears. This gear system can provide at least six forward speeds, and one or two reverse speeds with a compact arrangement.
