What is the purpose of a torque link on an oleo strut?

The purpose of a torque link on an oleo strut is primarily to keep the wheel in alignment during operation. This component plays a critical role in maintaining the correct orientation of the wheel relative to the strut and the fuselage. By doing so, it ensures that any forces acting on the wheel during taxiing, takeoff, or landing do not result in unwanted movement or misalignment, which could lead to increased wear or potential failure of the landing gear system.

The torque link allows for controlled movement and alignment adjustments, particularly during dynamic conditions, such as when an aircraft is maneuvering on the ground. Its design is such that it provides stability and protects structural integrity, minimizing the risk of misalignment that could impact handling and safety.

In contrast, while a torque link has a role in the overall function of the landing gear, it does not support the weight of the aircraft directly (which is the function of the oleo strut itself), nor does it act as a shock absorber (that function is performed by the strut's fluid and gas system). Additionally, it is not merely a connector between the strut and the landing gear; its specific intent is to manage torque and alignment.
