Abstract

The invention relates to a long shifting fork type control surface driving mechanism. The long shifting fork type control surface driving mechanism comprises a motor. The motor is fixedly mounted on a shell of a steering engine and is coaxially and fixedly connected with a motor gear. The motor gear is engaged with a transmission gear. The transmission gear is connected with a lead screw nut rotation stopping structure. The lead screw nut rotation stopping structure comprises a lead screw. The lead screw is engaged with a nut to implement transmission of up-down movement of the lead screw nut. The lead screw nut rotation stopping structure is provided with a force arm structure with a shifting fork. The force arm structure is provided with first bearings and is driven by the nut to enable the shifting fork to drive a control surface to rotate around a rudder spindle through the first bearings. The long shifting fork type control surface driving mechanism has the advantages of being simple in structure, capable of adjusting the size of the structure according to application to adapt to different types of steering engines, low in cost and wide in application range.

Description

technical field [0001] The invention relates to a long shift fork type rudder surface driving mechanism. Background technique [0002] A guided weapon is a space flight weapon composed of an electronic equipment compartment, an engine, a control system and a remote sensing system. During the flight of the guided weapon, the computer needs to issue different commands to control the rudder surface to rotate around the rudder axis to generate control force and torque to meet different flight attitude angles, so that the missile can fly according to the established target trajectory. Among them, the drive Torque and the resistance moment generated by the steering gear during flight are factors that need special consideration in the design process. In the design process, due to factors such as the space limitation of the steering gear, it is often necessary to make a reasonable optimization of the control torque of the rudder surface. At the same time, it is necessary to reason...
