    Abstract: A high flow high pressure hydraulic solenoid valve (26) includes a proportional 5 solenoid (56) and a valve body (30) operatively associated with the solenoid (56). The valve body (30) has a valve bore (32) and at least two fluid ports (38, 40) for fluid communication with the valve bore (32), wherein one of the at least two fluid ports (38, 40) includes an undercut (38b, 40b). The high flow high pressure hydraulic solenoid valve (26) also includes a valve member (42) 10 axially and slidingly disposed within the valve bore (32). The valve member (42) has a plurality of valve elements (44) spaced axially along the valve member (42). At least one of the valve elements (44) has a metering face (76a, 76c) acting with the undercut (38b, 40b). The one of the at least two fluid ports (38, 40) has two openings (82) located approximately one hundred eighty (180) degrees from each other in the valve body (30) and the valve member (42) has a control 15 module port (49a) configured to be ninety degrees from the at least one fluid port to balance pressure on the valve member (42) during high flow conditions.

    Abstract: A high flow high pressure hydraulic solenoid valve (26) includes a proportional solenoid (56), a valve body (30) operatively associated with the solenoid (56), the valve body (30) having a valve bore (32) and at least one fluid inlet port (38) for fluid communication with the valve bore (32) and at least one fluid outlet port (40) for fluid communication with the valve bore (32), a valve member (42) axially and slidingly disposed within the valve bore (32), the valve member (42) having a plurality of valve elements (44) spaced axially along the valve member (42), and at least one of the valve elements (44) having a metering face (76a, 76c) adapted to control the pressure of pressurized fluid between the at least one fluid inlet port (38) and the at least one fluid outlet port (40) of the valve body (30) and including a flow force compensating annular void (78a, 78c) to meter out fluid flow from the at least one fluid inlet port (38) to the at least one fluid outlet port (40) to minimize hydraulic, steady state flow forces on the valve member (42) during high-flow conditions.

    Abstract: A solenoid assembly includes a solenoid adapted to be coupled to a solenoid connecting member, with the solenoid connecting member extending from a support member. The solenoid assembly also includes a retaining bracket having a body portion and a securing portion extending from the body portion. The body portion is adapted to be removably coupled to the solenoid connecting member, and the securing portion is removably coupled to the solenoid. The retaining bracket is moveable between an unsecured position, and a secured position. The securing portion of the retaining bracket provides a spring force to the solenoid when the retaining bracket is in the secured position such that the solenoid is biased toward the solenoid connecting member to secure the solenoid between the solenoid connecting member and the securing portion of the retaining bracket.

    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)。
