Definition
A pair of hinged metal links connecting the upper fixed cylinder of a landing gear shock strut to the lower sliding piston, allowing the piston to move up and down to absorb landing loads while preventing it from rotating within the cylinder. Also called scissors or torque arms.
Plain English
Two hinged arms on a landing gear leg that let the wheel move up and down when the strut compresses but stop the wheel from twisting sideways.
Context Anchor
Seen during preflight inspection and in maintenance discussions around the nose gear or main landing gear.
Derivation
Torque means a twisting force. The links are called torque links because their job is to resist torque -- they hold the lower part of the strut from rotating relative to the upper part while still allowing it to slide.
Why Pilots Care
They keep the wheels aligned for steering and prevent uncontrolled rotation that could damage the strut or cause handling problems on the ground.
Intuition Check
Torque links are not parts that make engine torque. They are links that prevent unwanted twisting in the landing gear.
Example Sentence 1
During preflight, the pilot checked the torque links on the nose gear for cracks and proper grease.
Example Sentence 2
After landing, the mechanic greased the torque links to keep the strut moving freely.
