ABSTRACT:
A two-way differential clutch having sprags. It includes a mechanism that permits the sprags to be inclined instantly in the opposite direction when the rotating direction of an input gear changes over. Two cages having different diameters are mounted between the cylindrical inner surface of an input gear and the cylindrical outer surface of a rotary shaft. The large-diameter cage is fixed to the input gear while the small-diameter cage is rotatably mounted on the rotary shaft. Sprags are received in pockets formed in both cages. A friction plate is rotatably mounted on the small-diameter cage near its end. It is pressed by a resilient member against a flange of the small-diameter cage. The friction plate is nonrotatably coupled to a gear case through a rotation stopper. With this arrangement, it is possible to create a large rotating speed difference between the large-diameter cage and the small-diameter cage when the rotating direction of the input gear changes over. Thus, the sprags can be instantly inclined in the opposite direction.
