  • Pneumatic suspension spring for a wheeled vehicle
    Patent number: 8333367
    Abstract: Various embodiments of an air spring end closure are disclosed. One has an outer part and an inner part joined together to provide a moment of inertia along an axis that is transverse to axial expansion and contraction of the air chamber that is greater than that of the outer part alone. Another has a part that is concave toward the chamber and contains one of a riser and a depression having a generally rectangular shape whose length runs transverse to the direction of expansion and contraction and that is widthwise centered on a diameter of the part. Still another has a part having an elliptical perimeter margin curled onto a similarly shaped axial end of a sleeve that provides the axial expansion and contraction.
