Problems solved by technology

Also due to the use of two-stage transmission, the transmission efficiency is not high, and what is achieved is the flapping of the wing up and down, which is far from the purpose of the UAV aileron rotating around the axis.

Abstract

The invention relates to a control surface differential drive mechanism suitable for an unmanned aerial vehicle. The control surface differential drive mechanism comprises a common module, a left aileron drive mechanism module and a right aileron drive mechanism module. A dual-output steering engine connecting rod (2) is driven by an electric steering engine (2) to rotate, and a left aileron rudder shaft (111) and a right aileron rudder shaft (112) are driven to rotate oppositely through movement of a left connecting rod (61), a right connecting rod (62), a left rudder shaft connecting rod (81) and a right rudder shaft connecting rod (82), so that a left aileron (121) and a right aileron (122) deflect oppositely. Differential drive of the left aileron and the right aileron is achieved through a dual RSSR space four-connecting-rod combined mechanism, movement synchronization of the left aileron and the right aileron is achieved, constant-speed transmission of the left aileron and the right aileron is achieved, meanwhile, the requirements for machining precision and tools are lowered, and manufacturing cost is reduced.

Description

technical field [0001] The invention relates to a rudder surface differential drive mechanism. Background technique [0002] The left and right ailerons of the UAV are symmetrically arranged on the trailing edge of the left and right wings, and are used to adjust the flight attitude of the UAV. When the left and right ailerons are neutral, the UAV is in level flight; When deflecting (differential), the drone rolls. As the mechanical transmission device of the aileron, the driving mechanism is connected to the electric steering gear of the power source on the one hand, and the aileron rudder surface of the actuator on the other hand, so as to convert the rotational motion of the electric steering gear into the deflection motion of the aileron around the rudder axis. According to the flight attitude control requirements of UAVs, the left and right ailerons are only used to control the roll of the aircraft, and the drive mechanism needs to differentially drive the left and rig...
