Abstract:
1. An electromechanical actuating assembly comprising: an actuator; a first drive motor providing actuator-moving power; a second drive motor providing actuator-moving power independent of the first drive motor; a first drive train including a first ballscrew for transferring actuator-moving power to the actuator; a second drive train including a second ballscrew for transferring actuator-moving power to the actuator; a first decoupling train for transmitting decoupling power to decouple the first drive train from the actuator; and a second decoupling train for transmitting decoupling power to decouple the second drive train from the actuator; wherein the assembly is operable in a D1 mode, whereat actuator-moving power is transferred only through the first drive train and whereat the second drive train is decoupled from the actuator; wherein the assembly is operable in a D2 mode, whereat actuator-moving power is transferred only through the second drive train and whereat the first drive train is decoupled from the actuator.
