摘要： An automated multi-speed transmission includes an engine clutch operable to establish a releasable drive connection between the engine and an input shaft, an output shaft adapted to transfer power to the driveline, and a synchromesh geartrain having a plurality of constant-mesh gearsets that can be selectively engaged to establish a plurality of forward and reverse speed ratios. The transmission also includes power-operated dog clutches for selectively engaging the constant-mesh gearsets, and a controller for controlling coordinated actuation of the engine clutch and the power-operated dog clutches. The power-operated dog clutch associated with the low and the top gear are used during downshifts and upshifts, respectively, to actuate a clutch assembly for synchronizing the speed of the input shaft and the selected gear prior to engagement of its corresponding dog clutch.
摘要翻译：自动多速变速器包括可操作以在发动机和输入轴之间建立可释放的驱动连接的发动机离合器，适于将功率传递到传动系统的输出轴，以及具有多个恒定啮合齿轮组的同步啮合齿轮选择性地接合以建立多个前进和后退速度比。变速器还包括用于选择性地接合恒定网格齿轮组的动力操作的离合器，以及用于控制发动机离合器和动力操作的狗离合器的协调致动的控制器。与低档和高档齿轮相关联的动力操作的爪形离合器分别用于降档和升挡期间，用于致动离合器组件，以在其相应的爪形离合器接合之前使输入轴和所选择的齿轮的速度同步。

摘要： A full-time all-wheel drive system for a motor vehicle equipped with a transversely mounted engine and transaxle includes a power take-off unit. The power take-off unit includes an interaxle differential which drives a first power path connected to the front wheels and a second power path connected to the rear wheels. The first power path includes a planetary final drive unit which drives a double planetary front differential unit that is interconnected to a pair of front axleshafts. The second power path includes a helical gearset and a bevel gearset which deliver power to a rear propshaft.
