    • A normally-engaged clutch is provided having a friction-element with a first side and an opposing second side, a first plate configured for pressing against the friction-element on the first side, and a second plate configured for pressing against the friction-element on the second side. The clutch also includes a biasing device configured to apply a first force to the second plate for pressing the second plate against the friction-element to engage the clutch. Additionally, the clutch includes an apply piston for applying a second force to the first plate, and a release piston for applying a third force to the second plate. The clutch is disengaged when the second plate is pushed away from the friction-element by the third force in the absence of the second force, and is engaged when the first plate is pressed against the friction-element by the second force.

    • An actuator shifts a selectable one-way clutch (SOWC) between a plurality of operating modes. A first spring has a preload compression that is equivalent to a first start pressure. A second spring, disposed adjacent to the first spring, has a preload compression that is equivalent to a second start pressure. A plunger movably contacts the first spring and a slide plate movably extends from the plunger. The slide plate engages the SOWC such that the SOWC shifts between the operating modes in response to movement of the slide plate. The first spring is compressible from beyond the preload compression to a first stop position as the pressure is increased from the first start pressure to a first stop pressure. The second spring is compressible from beyond the respective preload compression to a second stop position as the pressure is increased from the second start pressure to a second stop pressure.
    • 执行器在多个操作模式之间移动可选择的单向离合器(SOWC)。 第一弹簧具有相当于第一起动压力的预压缩压缩。 与第一弹簧相邻设置的第二弹簧具有等于第二起动压力的预压缩压缩。 活塞可移动地接触第一弹簧和从柱塞可移动地延伸的滑动板。 滑板接合SOWC,使得SOWC响应于滑板的运动而在操作模式之间移动。 当压力从第一起始压力增加到第一停止压力时,第一弹簧可从超过预压缩压缩到第一停止位置。 当压力从第二起始压力增加到第二停止压力时,第二弹簧可以从相应的预压缩压缩到第二停止位置。
