The invention provides an aircraft control mechanism and damper anti-lock transmission device which comprises a connecting rod A and a connecting rod B. One end of the connecting rod A is connected with a damper through a knuckle bearing A, the other end of the connecting rod A is provided with a blind groove, the outer surface of the connecting rod A is further provided with a guide hole and a positioning hole, and the guide hole and the positioning hole are communicated with the blind groove. A sliding pin and a shear pin are fixedly connected to the connecting rod B, one end of the connecting rod B is sleeved with the blind groove, the sliding pin is sleeved with the guide hole, the shear pin extends out of the positioning hole, and one end of the connecting rod B is connected with the aircraft control mechanism through a knuckle bearing B. By the adoption of the technical scheme, when the four-connecting-rod mechanism in the eddy current damper is stuck, inertia force generated by an aircraft mechanical control mechanism on the connecting rod B forces the shear pin to be snapped, the acting force is transmitted to the eddy current damper through the sliding pin and the connecting rod A, the corresponding four-connecting-rod mechanism is released from the dead point position, and therefore the four-connecting-rod mechanism in the eddy current damper is released from the dead point position. And safe operation of the damper and the aircraft control mechanism is ensured.
本发明提供一种飞机操纵机构与阻尼器的防抱死传动装置,包括连杆A和连杆B,连杆A的一端通过关节轴承A与阻尼器连接,连杆A的另一端设置有盲槽,连杆A外表面还设置有导孔和定位孔,并且导孔、定位孔分别与盲槽连通,连杆B上分别固连有滑销和剪断销,连杆B的一端套合于盲槽内,使滑销套合于导孔内并且使剪断销经由定位孔伸出,连杆B的一端通过关节轴承B与飞机操纵机构连接。采用本发明的技术方案,当涡电流阻尼器内的四连杆机构卡死时,飞机机械操纵机构对连杆B产生的惯性力迫使剪断销被拉断,该作用力再经由滑销、连杆A传递至涡电流阻尼器,使相应的四连杆机构从“死点”位置解脱出来,保证了阻尼器和飞机操纵机构的安全运行。
