    摘要： A full-time two-speed transfer case is equipped with an integrated planetary gearset assembly and a range shift mechanism to provide high-range and low-range drive connections. The integrated planetary gearset assembly includes a first gearset which acts as a two-speed reduction unit and a second gearset which acts as an interaxle differential. The synchronized range shift mechanism is arranged to concurrently move two components of the first gearset and can be synchronized to permit on-the-move range shifts. The transfer case is also equipped with a dual-mode bi-directional overrunning clutch and a mode shift mechanism to establish automatic full-time and locked four-wheel drive modes.

    摘要： A full-time two-speed transfer case (20) is equipped with an integrated planetary gearset assembly (42') and a range shift mechanism (86') to provide high-range and low-range drive connections. The integrated planetary gearset assembly (42') includes a first gearset (48') which acts as a two-speed reduction unit and a second gearset (50) which acts as an interaxle differential. The synchronized range shift mechanism (86') is arranged to concurrently move two components (68', 70') of the first gearset (48) and can be synchronized to permit on-the-move range shifts. The transfer case (20) is also equipped with a dual-mode bi-directional overrunning clutch and a mode shift mechanism to establish automatic full-time and locked four-wheel drive modes.

    摘要： A controllable, multi-mode, bi-directional overrunning clutch assembly (58) and a mode shift system (60) are adapted for use in a transfer case (16) for transferring drive torque from a primary output shaft (18) to a secondary output shaft (32) so as to establish four-wheel drive modes. The clutch assembly (58) includes a first ring (118) journalled on a first rotary member (32), a second ring (124) fixed to a second rotary member (114), and a plurality of rollers (134) disposed in opposed cam tracks formed between the first and second rings. The first ring (118) is split to define an actuation channel having a pair of spaced end segments. An actuator ring (138) is moveable between positions engaged with and released from the end segments of the first ring (118). The shift system (60) includes a moveable clutch actuator which controls movement of the actuator ring (138) for establishing an on-demand four-wheel drive mode and a locked or part-time four-wheel drive mode.

    摘要翻译： 可控的多模式双向超越离合器组件（58）和模式换档系统（60）适用于用于将驱动扭矩从主输出轴（18）传递到次级的转移箱（16） 输出轴（32），以便建立四轮驱动模式。 离合器组件（58）包括安装在第一旋转构件（32）上的第一环（118），固定到第二旋转构件（114）的第二环（124）和布置在相对的第二旋转构件 形成在第一和第二环之间的凸轮轨道。 第一环（118）被分割以限定具有一对间隔开的端段的致动通道。 致动器环（138）可在与第一环（118）的端部段接合并从其释放的位置之间移动。 换档系统（60）包括可移动离合器致动器，其控制致动器环（138）的运动，用于建立按需四轮驱动模式和锁定或兼职四轮驱动模式。
