  • Dual motor power unit shaft coupler
    Patent number: 12135062
    Abstract: A shaft coupler having first and second spindles adapted to be secured to a first and second output shafts of first and second motors, respectively. A locker ring is assembled to the first spindle, and a locker carrier is assembled to the second spindle. A coil is carried by the locker carrier and switches between an energized state wherein the coil shifts the locker ring to slide into engagement with the second spindle to lock the first and second output shafts together, and a deenergized state wherein a spring biases the locker ring out of engagement with the second spindle to unlock the first and second output shafts from each other. A first set of locking teeth are disengaged from a second set of locking teeth when the coil is deenergized, and are engaged when the coil is energized.
