The air rudder and gas rudder linkage unlocking mechanism based on the steel ball lock is designed to be of a two-stage structure, a driving stage and an output stage share one shell, an output piston is installed in an output piston cavity in the left side of the shell, a driving piston is installed in a driving piston cavity in the right side of the shell, and the output piston and the driving piston achieve interlocking in different states through steel balls. And a large locking force is provided. Meanwhile, springs are installed at one end of the output piston and one end of the driving piston respectively and used for keeping the linkage or unlocking state of the mechanism. In addition, after the output piston is unlocked in place, the two reeds are conducted, and unlocking in-place state information is transmitted to a system for mechanism state feedback. On the basis of the steel ball lock principle, a double-piston linkage unlocking mechanism is designed, double-redundancy design is adopted, short-time electrification is needed only during state switching, linkage and unlocking states are power-off, the working reliability of the linkage and unlocking states under long-time and complex working conditions can be guaranteed, and repeated testing can be achieved.
本发明公开了一种基于钢球锁的空气舵与燃气舵联动解锁机构,设计为两级结构,驱动级、输出级共同一个壳体,输出活塞安装在壳体左侧输出活塞腔,驱动活塞安装在壳体右侧驱动活塞腔,输出活塞和驱动活塞依靠钢球实现不同状态互锁,提供较大的锁定力。同时,输出活塞和驱动活塞一端分别安装有弹簧用于保持机构联动或解锁状态。此外,输出活塞解锁到位后使两个簧片导通,将解锁到位状态信息传递给系统用于机构状态反馈。本发明基于钢球锁原理,设计了双活塞形式的联动解锁机构,采用双冗余设计,仅在状态切换时需要短时通电,联动和解锁状态均为失电,可保证长时间、复杂工况下联动和解锁状态工作可靠性,并可实现重复测试。
