摘要： A vehicle includes a front-wheel drive (FWD) transmission having a case, a selectable one-way clutch (SOWC) indexed to the case, pressurized fluid, and a valve body assembly (VBA). The VBA has a piston in communication with the fluid, a return spring, and an actuator plate in continuous contact with or connected to each of the piston and a shift lever of the SOWC. Fluid moving the piston and plate in one direction locks the SOWC to enable a reverse mode, and the spring moves the piston and the plate in another direction to unlock the SOWC in a forward mode. A method prevents spin losses in the FWD transmission by positioning a two-mode SOWC within a case, positioning a VBA adjacently and externally to the case, and admitting pressurized fluid into the VBA to engage the SOWC only during a reverse operating mode.

摘要： A hydraulic one-way clutch assembly (HOWC) is configured for use in a vehicle transmission. The HOWC assembly includes a non-rotatable disc and a rotatable disc. The non-rotatable disc extends about an axis and defines at least one exhaust port extending therethrough. The rotatable disc extends about the axis and is disposed axially adjacent the non-rotatable disc. The rotatable disc is configured to rotate relative to the non-rotatable disc, about the axis, between a closed position and an open position. The rotatable disc covers the exhaust passage when the rotatable disc is in the closed position to prevent fluid from flowing out through the at least one exhaust port. The rotatable disc uncovers the exhaust port when the rotatable disc is in the closed position to allow fluid to flow out through the at least one exhaust port.

摘要： A selectable one-way clutch assembly (SOWC) includes a first race, a second race, a plurality of rockers, and a selector ring. The first race and the second race each surround the first axis. Each of the rockers selectively hold torque in a rotational direction to establish a clutch operating mode. The selector ring defines a plurality of windows and is configured to rotates about the first axis to align at least one of the windows to establish one of the plurality of different clutch operating modes. The SOWC is engaged by rotating the selector ring about the first axis to align at least one of windows in a predetermined manner. Alignment allows at least one of the rockers to engage the second race in a radial direction to hold torque in at least one rotational direction.

摘要： A crimping apparatus and method are provided that enable secure crimping of objects to one another even when the objects are subject to thermal or stress cycling. Specifically, an apparatus for crimping a work-piece includes a die pair with a first die that defines a first groove characterized by a first cross-sectional shape as well as a second die opposing the first die. The second die defines a second groove characterized by a second cross-sectional shape different than the first cross-sectional shape. When the dies are moved together for crimping the work-piece, the first and second grooves are aligned to define a die cavity with a compound cross-sectional shape for crimping the work-piece.

摘要： A SOWC for use with a vehicle transmission is provided. The clutch includes outer and inner elements, also referred to as races, with the latter oriented concentrically within the former about an axis of rotation. A selection mechanism, which may be annular plates operatively connected with the side of the races and with one another, is selectively rotatable with respect to the inner and outer elements between different positions. Pivotable rocker elements are positioned between the races and are movable along cammed slots of the annular plates when the annular plates are rotated to establish a forward, a reverse, and a neutral operating mode corresponding with the different positions of the annular plates. In some embodiments, in the neutral operating mode, none of the rocker elements are in contact with the inner race.

摘要： A selectable one-way clutch (SOWC) is provided for use with a vehicle transmission, and has a first race with a plurality of strut pockets, a moveable selector plate, symmetrical torque-holding elements or struts, and a second race that is rotatably engageable with a torque input device. The selector plate has a plurality of windows, and the struts selectively prevent rotation of the second race in either rotational direction depending on the position of the selector plate. The struts have a cylindrical portion and a pair of strut wings each having a free end. The strut wings connect to the cylindrical portion, and a different one of the free ends engages a strut pocket when an opposite strut wing is depressed in order to prevent rotation of the second race.

摘要： A load floor assembly includes a load floor and a frame. The frame supports the load floor, and the load floor is movable with respect to the frame between a first position in which the load floor is entirely located within a vehicle cargo area, and a second position in which at least a portion of the load floor extends rearward of a rear body opening. The load floor is preferably movable to a third position forward of the first position in which increased vehicle body floor space is exposed adjacent to the rear body opening. A ramp surface supports the forward portion of the load floor in the third position to prevent a cantilevered condition. The load floor preferably includes two handles that are operative to disengage a latch for selective movement of the load floor between the positions.
