Webb1 jan. 2011 · Without careful examination, a clutching sequence may be mistaken for a usable clutch layout for an AT. For example, based on the Simpson gear train in Fig. 1, four clutching sequences were derived, as shown in Fig. 2.Each X Li in the clutching sequence table indicates that the corresponding clutch connected to link i is activated for that gear. Webb4 Planet gears (pinions) A typical gear train includes the input shaft; planetary gear set, and output shaft. Two different types of gear trains are used. A simple, or “Simpson,” gear train and a compound or “Ravigneaux” gear train. A planetary gear set has three members: the ring gear, the sun gear, and the pinion (or “planet”) gears. Webb1 maj 2024 · This task is all the more difficult the more PGT stages are included in the gear unit. In [45] Simpson Gear Train is analyzed and the gear ratio formula for G1 is given as Eq. (9).

"Webb10 mars 2024 · A planetary gear can also be used as a so-called direct drive. The carrier and the sun gear are firmly fixed to the ring gear. In this case, the rotary motion is transmitted directly from the input shaft to the output shaft (transmission ratio 1:1). Such a direct drive is used, for example, in three-speed gear hubs as the “2nd gear”. " - Simpson gear train
