  • Patent number: 9764613
    Abstract: A suspension system for a vehicle having a frame includes a first interface member configured to be positioned on a first lateral side of the frame and a second interface member configured to be positioned on an opposing second lateral side of the frame. The first interface member and the second interface member are positioned along a common central axis. The suspension system also includes a first swing arm coupled to the first interface member and configured to rotate about the common central axis, a second swing arm coupled to the second interface member and configured to rotate about the common central axis, and a sway bar coupled to the first interface member and the second interface member. The sway bar is positioned coaxially with the common central axis and extends between the first swing arm and the second swing arm.

  • Patent number: 9016703
    Abstract: A suspension system for a heavy duty truck or trailer is disclosed as having a frame and including a first swing arm having a first elongated portion and a first mounting member having a central axis and coupled to the first elongated portion. The suspension assembly also includes a second swing arm including a second elongated portion and a second mounting member having a central axis and coupled to the second elongated portion. The second mounting member is coaxially aligned with the first mounting member to define an axis of rotation for the first swing arm and the second swing arm. The suspension assembly finally includes a connector coupled to at least one of the first mounting member and the second mounting member and a sway bar having a central axis, wherein the sway bar is coupled to the first swing arm and the second swing arm and positioned such that the central axis of the sway bar is coaxially aligned with the axis of rotation for the first swing arm and the second swing arm.
