Abstract: Methods and systems for a gear mechanism that includes one or more actuators operable to activate or deactivate in order to drive or be driven by sequential engagement with one or more cam features incorporated within an interior of a ring gear.

Abstract: A self-releasing lock mechanism is provided and is configured to lock a driveshaft that is in mechanical communication with a rotor to mechanical ground via a flange in a motor housing. The self-releasing lock mechanism includes a ground lock housing having a locking arrangement configured to selectively engage a second end of the rotor. Locking pins extend from the ground lock housing and are configured to pass through the flange region of the motor housing. A locking plate includes the driveshaft and locking sites that are adapted to selectively receive the locking pins. A biasing member is disposed between the ground lock housing and the flange region to bias the ground lock housing away from the flange region. The locking arrangement engages the second end of the rotor to overcome the bias from the biasing member when the locking pins are received in locking sites.
