Abstract

A rotational coupling device drives an output synchronous with either of two inputs. The device includes a hub disposed about an axis and an output member supported on the hub for rotation about the axis. First and second input members disposed about the hub are configured to rotate in first and second rotational directions and at first and second speeds, respectively, with at least one of the directions and speeds differing. A clutch member is disposed axially between the input members and coupled to the output member. An electromagnet is on an opposite side of the second input member relative to the clutch member. When the electromagnet is deenergized, the clutch member engages the first input member and the output member rotates with the first input member. When the electromagnet is energized, the clutch member engages the second input member and the output member rotates with the second input member.
