  • Patent number: 10137749
    Abstract: An air spring with damping characteristics for a suspension assembly of a heavy-duty vehicle includes a bellows and a piston. The bellows includes a bellows chamber. The bellows is attached to a main member of the heavy-duty vehicle and to the piston. The piston includes an open bottom that is sealingly closed by a disc attached to the open bottom. The piston and the disc define a piston chamber. The piston is mounted on the suspension assembly of the heavy-duty vehicle. The bellows chamber and the piston chamber are in fluid communication with each other via at least one opening, wherein airflow between the bellows chamber and the piston chamber provides damping to the suspension assembly of the heavy-duty vehicle.
    Type: Grant

  • Patent number: 8851492
    Abstract: An axle/suspension system for heavy-duty vehicles having a frame and at least one suspension assembly operatively connected to the frame, the axle/suspension system including a mechanical stop having a plurality of links and a first end and a second end, the second end rigidly attached to the suspension assembly and the first end rigidly attached to the vehicle frame, wherein the first end and the second end control a distance between the first end and the second end, and control the plurality of links to attain a movement tolerance range of said mechanical stop from about 0.0 inches to about 2.0 inches.
