ABSTRACT:
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.
