[CN 201710586150.9] Dual redundant hydraulic mechanical clutch mechanism for mechanical backup actuator
[CN 201710586150.9] A dual redundant hydraulic mechanical clutch mechanism for mechanical backup actuators Title: A dual redundant hydraulic mechanical clutch mechanism for mechanical backup actuators Application number: CN 201710586150.9 Applicant: China Aviation Industry Corporation Xi'an Flight Automatic Control Research Institute Application date: 2017-7-18 Patent type: Invention application The present invention discloses a dual redundant hydraulic mechanical clutch mechanism for mechanical backup actuators, which is characterized: it includes a hydraulic lock (1) and two sets of hydraulic-mechanical conversion control mechanisms, each set of hydraulic-mechanical conversion control mechanism is respectively matched with the hydraulic lock (1), and when the working mode of the actuator is faulty, the intervention of the mechanical backup control function is realized. By designing a dual redundant hydraulic mechanical clutch mechanism, the invention realizes the conversion between manual manipulation and other manipulation functions, improves the reliability and safety of clutch conversion, and avoids modal conversion failure, functional disorder or hydraulic shock that may be caused by the traditional clutch mechanism.
