Abstract
Description
technical field
[0001] The invention relates to a double rocker arm transmission mechanism suitable for a movable rudder surface of an aircraft, belonging to the field of mechanism device design. Background technique
[0002] In order to control the flight attitude in real time, multiple active rudder surfaces are generally set on the aircraft. The transmission mechanism is an important device that transmits the active force of the servo actuator to manipulate the movable rudder surface for deflection.
[0003] At present, the drive of the movable rudder surface mostly adopts the form of motor direct drive or single rocker mechanism drive. The motor direct drive mode is that the motor rotor is directly connected to the rudder shaft, and the rudder surface is driven to deflect by the rotation of the motor; the single rocker arm mechanism is driven by a linear servo actuator to push the rocker arm fixed on the rudder shaft to deflect, driving The rudder deflects. The above-...
