ABSTRACT:
A clutch adapted for use in a four-wheel drive vehicle or the like and between concentric driving and driven members having a plurality of axially extending grooves opening radially toward the other member. A plurality of rollers are disposed within the grooves. Torque responsive means moves the rollers radially out of the grooves to one edge thereof and into contact with the driven member, thereby locking the driven member to the driving member whenever the driving member rotates faster or slower than the driven member. Means responsive to the driven member rotation displaces the rollers from one edge of the grooves to a position on the opposite edge of the grooves and into re-engagement with the driven member, thereby locking the driven member to the driving member whenever the driving member attempts to rotate slower than the driven member.
