Abstract
An overrunning accessory decoupler with a locking mechanism provides the desired overrunning accessory decoupler functionality and also permits torque to be transferred from the accessory to which the decoupler is installed to the drive of the engine when desired. In one embodiment, the decoupler includes a locking mechanism that is controlled by centrifugal forces developed in the decoupler to lock the decoupler to permit the accessory to transfer torque to the drive to start or boost the engine. In another embodiment, the decoupler locking mechanism includes an electromagnet that can be energized to lock and/or unlock the decoupler.
