Aircraft foot control mechanism for preventing misoperation of brake

Abstract

The invention belongs to the field of aircraft control system design, in particular to an aircraft foot control mechanism for preventing the misoperation of a brake. Generally designed to control therudder deflection with left and right foot pedals on the soles of the feet, and to control the wheel brakes with foot pedals on the tips of the feet. Ideally, the brake mechanism and the rudder pedalmechanism operate independently and do not interfere with each other. An aircraft foot control mechanism capable of preventing misoperation of a brake, An upper rock arm of that brake, a pedal rockerarm, a brake tie rod and a low rocker arm of the brake form a parallel four-bar linkage mechanism on the bracket, the lower rocker arm of the brake also has a pullback arm, a pullback spring is arranged between the end of the lower rocker arm of the brake and the bracket, and a torque opposite to the brake direction is applied to the pedal plate during the rotation of the pedal rocker arm; The pedal plate has a pedal plate lower protrusion below its rotational axis. Improve man-machine efficiency, increase handling comfort, can prevent pedal pedal pedal mistakenly; The invention has the advantages of simple structure and convenient installation and adjustment.

Description

technical field [0001] The invention belongs to the field of aircraft control system design, in particular to an aircraft foot control mechanism for preventing false braking. Background technique [0002] The rudder control system and braking system of transport aircraft are usually operated by the foot control mechanism, which is generally designed to control the rudder deflection by pushing the left and right pedals with the soles of the feet, and control the wheel brakes by pressing the pedals with the toes. Ideally, the brake mechanism and the rudder mechanism operate independently and do not interfere with each other.

Problems solved by technology

[0003] Chinese Patent Publication No. CN202481306, published on October 10, 2012, the name of the utility model is an aircraft foot-operated brake mechanism, the application discloses an aircraft foot-operated brake mechanism, which solves the brake pressure when the aircraft is stopped If it is too low, it is safe and reliable to park the aircraft on the ground. The disadvantage is that the brake mechanism is misoperated when the rudder is pushed during use, especially during the landing process of the aircraft. For aircraft without ground protection function, the rudder is used to correct the aircraft course During the runway, the brake mechanism malfunctions, the wheels of the aircraft are locked when the aircraft touches down, and the wheels slide and rub against the ground, causing the tires of the aircraft to wear out and be scrapped, and even a puncture may cause a flight accident
