Webb28 juni 2024 · Most of the current methods for estimating gear trains mechanical efficiency require the decomposition of gear transmissions in basic structural elements or planetary gear units (PGU). These are two degrees-of-freedom components whose mechanical efficiency has a deep influence on the overall device. 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.
