  • Patent number: 11597439
    Abstract: A chassis for a vehicle includes a frame having a first end and an opposing second end. The frame includes a first frame rail defining a first channel, a second frame rail defining a second channel and that is spaced from the first frame rail, and a cross member assembly coupled to the first end of the frame and extending between the first frame rail and the second frame rail. The cross member assembly includes a first end plate positioned within and releasably received by the first channel of the first frame rail, a second end plate positioned within and releasably received by the second channel of the second frame rail, and a cross member extending between the first end plate and the second end plate.
    Type: Grant

The frame has a first frame rail defining a first channel and a second frame rail defining a second channel. The second frame rail is spaced from the first frame rail. The frame assembly further includes a cross member assembly coupled to the first end of the frame and extending between the first frame rail and the second frame rail. The cross member assembly has a first end plate positioned within, and releasably received by, the first channel of the first frame rail; a second end plate positioned within, and releasably received by, the second channel of the second frame rail; and a cross member extending between the first end plate and the second end plate.

  • Publication number: 20050041331
    Abstract: A disc stabilization system comprises a spinning disc with a disc surface deflectable by shock. The disc surface is in contact with a gas layer adjacent the disc surface. When the suspension system is subjected to a mechanical shock, the disc can deflect. The amplitude and duration of the deflection due to mechanical shock is limited by a wing feature. The wing feature includes an aerodynamic surface that interacts with the gas layer to generate an aerodynamic force on the disc surface. A strut supports the wing feature over the disc surface in a position such that the aerodynamic force increases as the disc surface deflects toward the aerodynamic surface.
