Abstract:
An actuator is provided for preventing rotation of a rotary component and includes a first pawl pivotable about a first pivot axis and engageable with the rotary component for preventing rotation of the rotary component in a first rotary direction. A second pawl is pivotable about a second pivot axis and engageable with the rotary component for preventing rotation of the rotary component in a second rotary direction opposite the first rotary direction. The pawls are each biased toward an engaged position with the rotary component by a pawl spring. A first and a second solenoid each include an electrically activated solenoid and an armature movable from a first position for holding the pawls out of engagement with the rotary component to a second position for allowing the pawls to be engaged with the rotary component.
