  • Patent number: 12491943
    Abstract: A vehicle having a primary mover, a charging system, multiple electric loads, and a controller. The charging system includes a charge storing device and an alternator. The alternator is configured to convert mechanical energy generated by the prime mover into electrical energy to charge the charge storing device. The multiple electrical loads are electrically coupled to the charging system via a power distribution module. The controller is communicably coupled to the charging system and is configured to receive an indication that an electrical output of the charging system is unable to provide sufficient electrical energy to each electrical load in the electrical loads. The controller is also configured to provide a control signal to the power distribution module in response to the indication. The control signal is configured to cause the power distribution module to decouple at least one of the electrical loads from the charging system.

  • 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.

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.
