International ClassesF16S 003/08B60D 007/00 Foreign Application Priority Data1997-04-22 DEAbstractA frame construction includes at least one nodal connection element and several tube-shaped frame elements connected thereto. The frame elements and the nodal connection elements are manufactured by hydraulic internal high pressure forming and are joined via plug-type connections. Each nodal connection element has at least two connections for adjoining frame elements. The nodal connection element consists of at least two internal-high-pressure-formed tube-shaped hollow bodies in a nested configuration. The hollow bodies are made of different materials, and have different cuts in the area of the connections--viewed in the longitudinal direction of the respective connection, allowing connection with frame elements made of corresponding different materials. In the area of each connection, one of the two hollow bodies, in addition to being connected in a plug-type connection with the adjoining frame elements made of the same material, is connected by an additional connection.Field of SearchRIGID ANGLE COUPLING, E.G., ELBOW OR U, ETC.Made of tubular members Corners and joints Top boards Assembled from prefabricated connectable sections Longitudinal frame member is tubular Shaping by direct application of fluent pressure Radially expanding internal tube Riveting Metal deforming with nonmetallic bonding Vehicular structural member making Static structure, e.g., a building component Openwork, e.g., a truss, joist, frame, lattice-type or box beam Frame component Having tubular member Having specific connector, etc. Joint, connector Lined DISTINCT LAYERS Bonded to each other Brazed, soldered or welded Metal JOINED SECTIONS | |
