Two sets of driving devices, a worm and gear, a piston rod, an outer cylinder and a displacement sensor are matched, an undercarriage folding and unfolding actuating cylinder and a flaperon actuating cylinder are conveniently designed in an all-electric dual-redundancy mode, the system safety can be improved, light weight and low cost of the whole machine are achieved, the control precision is high, and later maintenance is convenient. The electric actuator cylinder adopts a dual-redundancy design, double motors work simultaneously under normal conditions, if one power supply, a control driver or a motor breaks down, the other power supply, the control driver and the motor can still work normally, actuation is completed, safe and reliable operation of the system is guaranteed, the displacement sensor and the two sets of driving devices are matched, the electric actuator cylinder adopts telex control, and operation is convenient. Electric execution is achieved, the control precision is high, the response speed is high, a BIT self-checking means can be conveniently adopted, system faults can be rapidly detected and positioned, special equipment is not needed in later maintenance, maintenance is convenient, and the cost is low.

    本发明公开了一种新型双余度电作动筒,两组驱动装置、蜗轮蜗杆、活塞杆、外筒和位移传感器配合,便于起落架收放作动筒、襟副翼作动筒采用全电双余度设计,可提高系统安全性,实现整机轻量化,低成本化,且控制精度高,便于后期维护,电作动筒采用双余度设计,正常情况下双电机同时工作,如遇到一路电源、控制驱动器或电机出现故障,另一路电源、控制驱动器和电机仍可正常工作,完成作动,保证系统安全可靠运转,位移传感器、两组驱动装置配合,电作动筒采用电传控制,电动执行,控制精度高、响应速度快,便于采用BIT自检手段,系统故障能快速检测与定位,且后期维护不需要专用设备,维护方便、费用低。
