An underbody for a vehicle includes a floorpan defining a part of an assembly, a rocker slidably engaged with the floorpan, and a rail slidably engaged with the floorpan. The assembly is formed as a unit about a first and a second bend axis.

One embodiment includes providing a contiguous tubular member including at least one of a first material or a second material, so that the tubular member has a wall thickness that varies along the length of the tubular member; bending the tubular member; and hydroforming the tubular member into a part.

Microencapsulated chemical(s), as water-soluble solid particles, are embedded in at least one the paint layers on the surface of a magnesium article used in an automobile. If the protective paint film is scratched or otherwise mechanically disturbed to expose the surface of the magnesium article the capsules will be ruptured. This will expose the encapsulated chemical(s) to ambient water enabling them to dissolve and form an aqueous solution capable of reacting with the exposed magnesium to form a protective passivating layer on the exposed magnesium to resist corrosion. In a second embodiment the encapsulated chemicals include a deliquescing compound for extraction of moisture from the atmosphere sufficient to induce dissolution of the passivating layer-forming chemical(s) and trigger the formation of the passivating layer in the absence of ambient water.

A tire includes a pair of sidewalls in spaced apart relation and extending substantially radially from a respective inner circumferential portion to a respective outer circumferential portion, a tread extending between and connecting outer circumferential portions of the sidewalls, at least a portion of a tire cavity defined by the tread and sidewalls, and a bead portion on the inner circumferential portion of each radially extending sidewall, the bead portion providing an engagement surface for engaging a wheel on which the tire is to be mounted, and a noise reducing foam disposed in at least a portion of the tire cavity.
摘要:
Iron impurities may be removed from volumes of molten aluminum or magnesium metals or alloys by applying a static magnetic field gradient to each of the molten metal volumes, or melts. The magnetic field gradient is applied to each of the melts so that separate-phase iron impurities suspended therein will move in the direction of the applied magnetic field and become concentrated in a predetermined region of the of the melts, thereby forming an iron-rich region. The remaining iron-depleted region of each of the melts can be physically separated from the as-formed iron-rich region and cast into shaped articles of manufacture or into semi-finished articles for further processing. Such articles will have a lower iron-content than the original molten metal volumes.
摘要:
A virtual-sunroof system for providing a virtual sunroof at an interior of a vehicle for viewing by a passenger of the vehicle. The system includes a virtual-sunroof imaging device configured and arranged at the vehicle to collect image information from an environment above the vehicle and create digital image data using the image information. The system also includes a virtual-sunroof projection device configured and arranged in the vehicle to be in communication with the virtual-sunroof imaging device for providing a virtual sunroof display. The virtual sunroof display provided (a) is viewable above a head of the passenger, (b) is formed using the image data, (c) represents accurately at the interior of the vehicle a rendition of the environment above the vehicle, and (d) has a size, shape, and location corresponding generally to a size, shape, and location that an actual conventional-type sunroof would have in the vehicle.
摘要:
The gravimetric and volumetric efficiency of lithium ion batteries may be increased if high capacity materials like tin and silicon may be employed as the lithium-accepting host in the negative electrode of the battery. But both tin and silicon, when fully charged with lithium, undergo expansions of up to 300% and generate appreciable internal stresses which have potential to spall off material from the electrode on each discharge-charge cycle, resulting in a progressive reduction in battery capacity, also known as battery fade. A method of reinforcing such electrode materials by incorporating within them fiber reinforcements or shaped, elongated reinforcements fabricated of shape memory alloy is described. Electrode materials incorporating such reinforcements are less prone to damage under applied stress and so less prone to battery fade.
摘要:
A process for fabricating sintered, substantially pore-free titanium aluminide articles with minor alloying element additions is disclosed. Such articles may find application as automobile engine valves and connecting rods and may be fabricated by rapidly sintering intimately mixed powders of substantially pure titanium and rapidly-cooled particles of aluminum alloyed with the minor alloying element(s).
摘要:
Unitary closure panels for automotive vehicles may be formed to have regions of different materials by a spray casting process. Separate sprays of different materials, for example two different metal alloys, are applied to touching regions of a spray application surface. The separate sprays may be applied sequentially or simultaneously to the forming surface to coat the respective regions so that the regions are contiguous or overlapping and a unitary body is formed. The spray formed body may be compressed and trimmed between facing surfaces to form a vehicle closure panel of specified outline, curvature, thickness, and porosity.
