Mechanical type airplane tread adjusting mechanism

Abstract

The invention relates to a mechanical type airplane tread adjusting mechanism, which comprises an adjusting handle, the adjusting handle is fastened and connected to one end of a steel rope, two first deflecting pulleys vertically disposed are provided at two sides of the steel rope and clamp the steel rope, the steel rope is bifurcated to two strands at the position of the first deflecting pulley and then connected to a left fitting pin and a right fitting pin, second deflecting pulleys have two and are respectively and fixedly arranged on a left connecting rod and a right connecting rod, two strands of steel rope respectively wind the second deflecting pulleys at two sides and then insert in the hole sites on the left connecting rod and the right connecting rod through the left fitting pin and the right fitting pin, reset compressed springs are provided over two fitting pins, two fitting pins are compressed in the hole sites of two connecting rods for tightly locking, and then two connecting rods are respectively assembled with the tread pedal at two sides as one body, one compression spring is provided below two connecting rods, one end of the compression spring is fixed, the other end is connected to a support rod below two connecting rods, several hole sites provided on two connecting rods are used for being inserted by two fitting pins. The mechanical type airplane tread adjusting mechanism is provided under the premise of minimum weight and minimum volume, so that position adjustment for the tread can be realized.

Description

technical field [0001] The invention relates to a basic structural part of an aircraft control system, in particular to a mechanical aircraft pedal adjustment mechanism. Background technique [0002] The pedals are the basic components of the aircraft control system, the output carrier of the pilot's control commands to the yaw direction of the aircraft, and one of the important main control systems of the aircraft. To accommodate the differences in the size of the pilots, the distance between the seat and the pedal mechanism must be adjustable. Due to the space limitation of the cockpit, the distance between the seat and the pedal mechanism is generally adjustable by adjusting the front and rear positions of the pedals. [0003] At present, the domestic aircraft pedal adjustment mechanism can be divided into two types: mechanical and electric. The pedal electric adjustment mechanism requires a large margin in terms of weight and space, and is not suitable for aircraft with...
