Refer to the figure
The function of a torsion link, or torque link, is to avoid movement of the inner cylinder within the outer cylinder. So when the aircraft is moving forward without turning there will not be much force on the torsion link. When the aircraft touches down with a strong cross-wind there might be some forces on the torque link, but most of the movement will be forward in line with the direction of the aircraft. When the aircraft is turning on the ground and especially turns with a small radius, the wheels will want to move forward whilst the aircraft is turning, this will cause a lot of load on the torsion link.
