Connecting rod mechanism of unmanned aircraft rudder system

Abstract

The invention discloses a connecting rod mechanism of an unmanned aircraft rudder system. The connecting rod mechanism of the unmanned aircraft rudder system comprises a steering engine rocker arm, a rudder rocker arm, a connecting rod, and connecting rod joints, wherein internal screw holes with internal threads are formed in the two end parts of the connecting rod; the turning directions of the internal threads of the two internal screw holes are opposite; external thread parts are arranged at one ends of the connecting rod joints; each of the two end parts of the connecting rod is respectively in threaded connection with the corresponding connecting rod joint; as for any one of the connecting rod joints, the external thread parts are screwed into the internal screw holes for a certain length; the other end of one of the connecting rod joints is movably connected with the lower end part of the steering engine rocker arm, and the other end of the other connecting rod joint is movably connected to the lower end part of the rudder rocker arm. The fixed structure form can bring convenience for adjusting the total length of the connecting rod under the situation that the connection between the connecting rod and the rocker arm is not removed, and further enables the connecting rod mechanism to be adjusted in place at a time; furthermore, a knuckle bearing can effectively adjust the turning clamping stagnation due to the assembly error.

Description

technical field [0001] The invention relates to a novel connecting rod mechanism of an unmanned aerial vehicle rudder system, which can conveniently adjust the distance between the center holes of the joints at both ends of the connecting rod under the condition that all parts are connected. Background technique [0002] The linkage mechanism of the UAV rudder system is a transmission mechanism for the steering gear to drive the rudder surface to rotate, usually in the form of a four-bar linkage. The steering gear drives the rocker arm of the steering gear, the rocker arm of the steering gear drives the connecting rod assembly, and the connecting rod assembly drives the rocker arm of the steering gear to deflect the rudder surface. [0003] The length of the connecting rod assembly in the connecting rod system is generally required to be adjustable, which can adjust the installation error of the steering gear rocker arm and the rudder rocker arm. [0004] At present, some o...

AI Technical Summary

Problems solved by technology

[0004] At present, some of the connecting rods of the rudder system linkage mechanism are separate parts, and the length cannot be adjusted. For some, it is necessary to connect all the parts of the linkage mechanism first, then test the length to be adjusted, and then remove the linkage assembly or at least release the connection at one end. Only by adjusting its length, can it be adjusted after repeated times, and the efficiency is low
