  "textContent": "The invention provides a powered retraction system for a wheel. The retraction system includes an actuation system to raise the wheel to a stowed position and to lower the wheel to a steer position. The actuation system includes: a motor that is operably connected to a rotatable torsion controller to rotationally drive the torsion controller about a torsion controller axis; a torsion element comprising opposing first and second ends; and a swing arm operably connected to the wheel axle and rotatable by the torsion controller about a swing arm axis to raise and lower the wheel. The first end of the torsion element engages with the rotatable torsion controller and the second end of the torsion element engages with the swing arm. When in the steer position, the torsion element is tensioned to urge the spring arm, and in turn the wheel, downwards.",
