  • Publication number: 20190047392
    Abstract: A vehicle underbody including a rear underbody structure, a rear differential, a sub-frame, and a traction battery is provided. The rear differential is mounted to the rear underbody structure. The sub-frame is mounted to the rear underbody structure rearward of the rear differential. The traction battery is mounted between the rear underbody structure and the sub-frame. A base portion of the traction battery defines a base portion plane that does not extend through the rear differential. The sub-frame may include at least two reinforcement members each having a ramp-shaped end extending toward the rear differential. The sub-frame may include a rear lateral member and a trailer hitch mount extending rearwardly therefrom. One of the reinforcement members and the trailer hitch mount may be aligned in parallel with a central longitudinal axis defined by the rear underbody structure.

  • Publication number: 20180222531
    Abstract: A roof structure is disclosed for a vehicle that comprises a roof bow including a wall forming part of an exterior roof surface of the vehicle. The wall defines a keyhole opening that is adapted to receive a retainer. A channel is provided on the wall below the keyhole opening that forms a water drain below the keyhole opening with a lower surface of the wall extending over the water drain. A retainer including an anchor portion and an accessory attachment portion extends upwardly from the anchor portion through the slot and is retained in the channel by the flanges.

  • Publication number: 20160168676
    Abstract: Methods of processing an air-quenchable aluminum alloy component are provided. The method may include solution heat treating the component, air-quenching the component, and artificially aging the component to a yield strength of at least 200 MPa. The air-quenching may include cooling at a rate of 6° C./s to 25° C./s. The solution heat treatment may include heat treating the component at a temperature of 520° C. to 540° C. and the artificial aging step may include heat treating the component at 235° C. to 255° C. for 0.5 to 2 hours. The disclosed methods may produce a high strength (e.g., over 200 MPa) and high bendability (e.g., r/t ratio up to 0.3) component that does not significantly distort during the quenching process. The disclosed methods may be used to produce structural components having complex shapes, such as multiple, non-coplanar mating surface, while staying within predetermined tolerances.

  • Patent number: 8544589
    Abstract: A deflector is attached to a frame on a vehicle in front of a front wheel which cooperates with the front wheel to glance a vehicle past a laterally offset impacting object. The deflector acts as a first boundary against the impacting object and the deflector turns the front wheel inboard to an inwardly turned position to act as a second deflecting boundary against the impacting object. The deflector and inwardly turned front wheel cooperate to deflect the vehicle past the object, such that the object passes outboard of a rocker member on the vehicle.
