An overrunning clutch, also known as a freewheel one-way clutch, is a mechanical device used to transmit rotational motion in one direction while allowing free rotation in the opposite direction. In this type of application, the different conditions of engagement and disengagement are repeated arbitrarily, when the Overrunning Clutch inner and outer races engage each other to transmit torque, and when the Overrunning Clutch continues overrunning through the difference in rotating speed and direction between the inner and outer races. This is the same behavior as a freewheel on the rear bicycle wheel.
