Abstract:
A sliding door for vehicles including a space frame formed from a U-shaped extruded aluminum tube and a crossbeam to which inner and outer aluminum door panels are attached. An elongated hardware carrier beam defines a channel configured to receive vehicle door hardware mounted on the exposed inside surface of the door. The overall weight of the door is about 20 pounds and the door is up to about 35 mm thick.
Abstract:

Abstract:
A joint structure is ideally suited for use in the manufacture of assemblies and subassemblies in aluminum structures. More particularly, the alternative joint structures and methods of forming joint structures facilitate the assembly of a vehicle body-in-white. The friction welded joints of this invention provide assemblies in which lineals and sheet, cast, or extruded components are joined together.

Abstract:
A tool for making simultaneously a plurality of parallel friction stir welds includes at least one shank for holding in a chuck or collet of a friction stir welding machine, a plurality of friction stir welding pins, and friction stir welding shoulders including at least four working surfaces adjacent said pins, the shoulders and pins mounted in axial relationship; dimensions of said friction stir welding pins and shanks corresponding to dimensions and spacings of said friction stir welds.
Abstract:
A sliding door (2) for vehicles includes space frame formed from an extruded aluminum tube to which inner (40) and outer (80) aluminum door panels are attached. The vehicle door comprises an inner panel (40, Fig. 5) having an inside surface (44) and an outside surface (43), said inner panel defining a window opening (41) and said outside surface (43) defining a U-shaped channe l (42) surrounding a portion of said window opening. A space frame (10, Fig 1) comprising a U-shaped member is received in the U-shaped channel (42) and ha s a pair of spaced apart legs (22, 24). An outer panel (80, Fig. 8) is fixed t o said outside surface (43) of said inner panel (40), such that a portion of each said leg of said space frame is positioned between said inner panel and said outer panel.

Abstract:
Friction stir welding tool (10) to facilitate stress reduction within the tool that may include a body (20), a pin (30), a tension member (50), and an end assembly (60), the tension member (50) and end assembly (60) facilitating axial compression of the pin (30). The tension member (50) may be decoupled from the pin (30) and/or body (20) of the tool (10) via one or more decoupling members (62). The end assembly (60) may comprise spring members (64) to provide an axial force to the tension member (50). The pin (30) may include various features to facilitate stress reduction proximal the pin (30).
