Planetary gear with a common carrier for the production of six forward - and a reverse gear position

摘要

An automatic transmission contains a first planetary gear set with a first rotation wheelset, rotatably mounted on a common carrier is supported and with a first sun gear and a second composite gear wheel, the both as a first ring gear as well as a second sun gear, is in driving engagement. A second planetary gear set comprises a second circulation wheelset, the rotatably on the common carrier is supported and with the third sun gear, the first composite gear wheel and a second composite gear wheel, the both as a second ring gear and also functions as a third ring gear, is in driving engagement. A third planetary gear set comprises a third cycle wheel set, the rotatably on the common carrier is supported and with a third sun gear and the second composite gear wheel is in driving engagement. A number of nested clutches and several brakes are used, for using a single carrier to provide six forward gears and one reverse gear.
