Abstract: An actuation device having a piston is used to actuate a mechanical or friction clutch by means of differential pressure. Two sides of a piston are pressurized, and the relative pressure between the two sides is decreased or increased to move the piston in either direction. The position of the piston may be determined using position feedback, or with springs of known spring rates, two piston areas, and knowing the pressures of the two areas. The actuation device may be used with a selectable clutch to actuate an actuation cam, and may also have application with other clutches requiring the ability to achieve multiple positions and clutch modes.

Abstract: A forward/reverse planetary gearset (412) may be adapted to employ multi-mode clutch modules (426, 430) in lieu of using only traditional friction clutches (326, 330). Such arrangement may reduce parasitic drag as well as achieve reductions in physical size of the gearset housing (408). Use of multi-mode clutch modules (426, 430) may offer either of or both forward and reverse controls of the planetary gearset (412). Thus, in at least one arrangement a multi-mode clutch (426) may provide forward clutch control while a friction clutch (330) provides reverse clutch control. In another arrangement the friction clutch (326) may provide the forward clutch control, while the multi-mode clutch (430) provides the reverse clutch control for the gearset (412). Finally, both forward and reverse controls of the gearset (412) may be provided via multi-mode clutches (426, 430), thus entirely avoiding use of any friction clutches (326, 330) for forward or reverse control functions of the planetary gearset (412).

Abstract translation: 前进/后退行星齿轮组（412）可以适​​于使用多模式离合器模块（426,430）来代替仅使用传统的摩擦离合器（326,330）。 这种布置可以减少寄生阻力并且实现减速齿轮箱壳体（408）的物理尺寸。 使用多模式离合器模块（426,430）可以提供行星齿轮组（412）的前进和后退控制。 因此，在至少一个布置中，多模式离合器（426）可以在摩擦离合器（330）提供倒档离合器控制的同时提供向前离合器控制。 在另一种布置中，摩擦离合器（326）可以提供前进离合器控制，而多模式离合器（430）为齿轮组（412）提供倒档离合器控制。 最后，可以通过多模式离合器（426,430）来提供齿轮组（412）的前进和后退控制，从而完全避免使用任何摩擦离合器（326,330）来进行前进或后退的行星齿轮组的功能 （412）。

Abstract: The selectable clutch may include a first actuator and a second actuator. Moreover, the selectable clutch may further include a first cam operatively associated with the first actuator and a second cam operatively associated with the second actuator. Furthermore, a first armature may be actuated by the first actuator and a second armature may be actuated by the second actuator such that the selectable clutch is configured to allow multiple modes of operation provided by a movement of the first and second cams according to different first and second armature positions.

Abstract: A multimode clutch may be adapted for selectively connecting and disconnecting front and/or rear axles from respective internal combustion engine and electric motor powertrains connected to such front and rear driving axles in a through-the-road hybrid vehicle. For example, the engine may be part of a front axle driven powertrain connected to the front wheels, while the motor may be part of a separate rear axle driven powertrain connected to the rear wheels, or vice versa. By selective disconnection of an axle not being actively driven, a real time reduction in parasitic losses may be achieved, leading to higher overall operating efficiencies. The multimode clutch offers greater flexibility over the use of standard friction clutches; each multimode clutch may provide four distinct operational modes for accommodating a wide diversity of driving conditions. For example, bi-rotational freewheeling of the rear axle may occur whenever the motor is not in use.
