Abstract

The invention provides a pull rod guiding mechanism for controlling over flight of a helicopter and belongs to the technical field of structure design for a controlling system of the helicopter. The mechanism comprises multiple guide units (5) and a supporting base (6), the supporting base (6) is fixed to the helicopter, the guide units (5) are fixed to the supporting base (6) side by side, each guide unit comprises a pull rod (51) and a guide cylinder (52), and the two ends of each guide cylinder (52) support the corresponding pull rod (51) through linear motion ball bearings (53) respectively. According to the pull rod guiding mechanism, the multi-channel motion transmission function can be achieved at the same time, linear or small-angle motion transmission can be achieved, and a largeamount of space is saved.

Description

technical field [0001] The application belongs to the technical field of structural design of a helicopter control system, and in particular relates to a tie rod guide mechanism for helicopter flight control. Background technique [0002] The layout of the helicopter control system is often limited by the surrounding airframe structure and other system components. Especially on heavy-weight helicopters, the length of the control wires is relatively large, and it is difficult to arrange multi-channel wires. [0003] The general motion transmission device of the flight control system is realized by the rod rocker, such as Figure 5 As shown, this form mainly includes support 1, rocker arm 2, pull rods 3, 4, etc., support 1 is installed and fixed on the structure, rocker arm 2 is installed on support 1, and the two ends of the pull rod are respectively connected to different rockers. arm. The pull rod receives the motion output transmitted by the rocker arm of the previous st...
