The invention belongs to the technical field of aircraft reverse thrust structure design, and particularly relates to a reverse thrust device floating pull rod which comprises a pull rod; a left pullrod head which is in threaded connection with one end of the pull rod; a right pull rod head which is in threaded connection with the other end of the pull rod, and connecting threads at two ends of the pull rod are opposite in screwing direction; a left rocker arm of which one end is hinged to one end of the left pull rod head, and the other end is hinged to one unit body in the reverse thrust device through a left knuckle bearing; a right rocker arm of which one end is hinged to one end of the right pull rod head, and the other end of the right rocker arm is hinged to the other unit in the reverse thrust device through a right knuckle bearing. According to the floating pull rod of the reverse thrust device, on the premise that the starting requirement of the reverse thrust device and therequirement for transferring loads between reverse thrust device unit bodies are met, it is not required that a floating lifting point and an installing lifting point of the reverse thrust device arecoaxial, the related requirements for manufacturing and assembling of the reverse thrust device can be lowered, and the production cost of the reverse thrust device is reduced.

    本申请属于飞行器反推力结构设计技术领域,特别涉及一种反推力装置浮动拉杆,包括:拉杆;左拉杆头螺纹连接在拉杆的一端端部;右拉杆头,螺纹连接在拉杆的另一端端部,且拉杆两端的连接螺纹旋向相反;左摇臂,一端铰接在左拉杆头的一端,另一端通过左关节轴承与反推力装置中的一个单元体铰接;右摇臂,一端铰接在右拉杆头的一端,另一端通过右关节轴承与反推力装置中的另一个单元体铰接。本申请的反推力装置浮动拉杆,在满足反推力装置开启要求和在反推力装置单元体之间传递载荷要求的前提下,不要求反推力装置浮动吊点与安装吊点同轴,能够降低反推力装置制造和装配的相关要求,减少反推力装置的生产成本。
