ABSTRACT:
A dual drive actuation system includes a driver gear, a pair of actuators with driven gears, and a transmission for switching the driver gear between the pair of actuators. The transmission is controlled by a solenoid, and the driver gear is powered by a motor. The dual drive actuation system can be used with different actuators that are changed based on their required usage, sizing and range of motion.
