Abstract

A cast light metal joining element and method of assembly with adjoining extruded light metal hollow section bearer member of a space frame type vehicle body. The joining element or casting includes at least two spaced apart, location points disposed along a surface wall thereof. The location points permit the casting to be held in a corresponding fixture at a desired positionally correct spatial orientation to facilitate the fitting and connection of adjoining frame elements with greater ease, accuracy and smaller tolerances. In one embodiment, the location points include integrally formed conical studs and/or conical depressions. In another embodiment, the location points include through-holes, either straight cylindrical or conically tapered. The studs, depressions and/or holes also served a dual function in providing a positive locking connection to add on components which have corresponding matingly engagable connection surfaces.
