    Abstract: A hydraulic circuit for moving a fluid includes an electric pump, a primary circuit, and a secondary circuit. The hydraulic circuit also includes a controller and a hydraulic control module. The hydraulic control module includes a solenoid valve assembly. Moreover, the controller is configured to control a pressure of the fluid at the output of the solenoid valve assembly. Finally, the hydraulic control module includes a switch valve assembly configured to selectively route the fluid from the pump to the primary circuit when the pressure of the fluid at the output of the solenoid valve assembly is lower than a predetermined pressure and to selectively route the fluid to the secondary circuit when the pressure of the fluid at the output of the solenoid valve assembly is greater than the predetermined pressure.

    Abstract: In an all-wheel drive (AWD) vehicle (10, 42), torque carrying connections are provided between the powertrain and all four wheels (12, 14, 22, 24). A multimode clutch module (50, 170) or clutches are provided to selectively disconnect two of the wheels (12, 14, 22, 24) from the powertrain during operating conditions where disconnection improves the performance and efficiency of the AWD vehicle (10, 42). The multimode clutch module (50, 170) may be installed at various locations of the AWD vehicle (10, 42), such as within a front or rear differential (20, 30), between a half axle (16, 18, 26, 28) and a differential (20, 30) or between a half axle (16, 18, 26, 28) and a corresponding wheel (12, 14, 22, 24), or within a transfer case (36) or power transfer unit (44).

    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)。
