  • Air spring with damping characteristics for heavy-duty vehicles
    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.

  • Pivotal connection for heavy-duty vehicle suspension assembly
    Patent number: 10017020
    Abstract: A suspension assembly of an axle/suspension system for a heavy-duty vehicle is mounted on the heavy-duty vehicle frame or sub-frame via a beam of the suspension assembly which is pivotally connected to a hanger connected to the vehicle frame. The pivotal connection includes the hanger, the beam, a bushing assembly and a fastener group, and a textured feature formed in at least one of at least a portion of the hanger, at least a portion of the bushing assembly, or at least a portion of the fastening means so that the textured feature inhibits relative movement of the bushing assembly with respect to the hanger.
