Definitions

  • connection node of at least two profiles made of sheet steel, in particular a frame structure of a vehicle body.
  • connection nodes Critical points of a frame structure for vehicle bodies, both in terms of production, as well as in terms of rigidity and durability, are the so-called connection nodes. These are places where at least two profiles are connected. Welded connections, as are possible in truck and bus construction on closed profiles, cannot easily be realized on profiles of a frame structure for passenger vehicles, which is dimensioned from sheet steel according to the lightweight construction principle, because of the thin wall thickness of the sheets used for the profiles. Therefore, prefabricated node elements are often used on the nodes. B. are produced by hydroforming a preformed from sheet steel (DE 196 53 509 AI). These node elements have connecting pieces, onto or into which the profiles of the frame structure, usually hollow profiles, can be plugged.
  • the plugged in or plugged in Hollow profiles are also welded to the node element.
  • the manufacturing effort for such a frame structure is great.
  • the weight of a frame structure produced with such node elements is also greater in comparison to a frame structure with directly connected profiles. After all, they offer practically no possibility to compensate for tolerances.
  • the object of the invention is to develop a connection node of a frame structure of a vehicle body consisting of profiles from the point of view of lightweight construction, which enables easy assembly of the profiles with a simple tolerance compensation at the connection nodes and has high rigidity.
  • the one profile consists of two parallel belts and at least one connecting web and with its opposite belt ends projecting beyond the connecting webs onto the other profile having two parallel belts or wall parts is, the belt ends of one profile abut the parallel belts or wall parts of the other profile and are thus firmly connected.
  • connection node With the connection node according to the invention, two profiles, in particular a frame structure of a vehicle body, can be easily and quickly combined with different joining technologies connect directly with each other.
  • the aspect of lightweight construction is taken into account.
  • a multiple tolerance compensation is possible during production, both in the axial direction of the profile with the belts and the connecting web, by plugging it less far onto the other profile, and in the axial direction of the other profile, by moving it in parallel on the other profile in its axial direction is, and finally with respect to the angle between the two profiles, because unlike the known node element with the connecting piece, no fixed angle is specified.
  • the design effort is very low because conventional profiles are assumed. Only the profile with the belts and the web must be adjusted so that the belt ends protrude from the web.
  • the use of the Davex profile mentioned is also advantageous for another reason. Since the web is clamped in grooves of the straps in a Davex profile, different materials and / or different material thicknesses can be used for the web and the straps in order to optimize the load during its manufacture. In addition, with a Davex profile which can be used for production-technical reasons over the webs on the longitudinal edges of the edge areas as a support for shear fields or other functional elements, which is not possible with other hollow profiles, such as pipes.
  • the weld seam can be provided at different points.
  • a first option is at the front edges of the protruding belt ends. For reasons of the highest possible rigidity, it is better to arrange the weld seam on the side edges of the protruding belt ends. It goes without saying that the front edges can also be welded on. It is also possible to weld the connecting web (s) of one profile to the adjacent wall part of the other profile. However, this is only possible if the web rests against this wall part.
  • connection node according to the invention is explained in more detail below with the aid of a drawing illustrating various exemplary embodiments. In detail show:
  • FIG. 3 shows a connection node of two profiles of a frame structure of a vehicle body in an embodiment modified from FIGS. 1 and 2 as a detail of the frame structure in view and
  • a connection knot is realized on a profile 1 designed as a hollow profile with a rectangular cross section and a profile 2 formed from two belts 2a, 2b and two webs 2c, 2d connected to it.
  • the straps 2a, 2b protrude with their strap ends 2a *, 2b * from the webs 2c, 2d.
  • Profile 2 is a so-called "Davex" profile (brand of ThyssenKrupp Stahl AG). It is characteristic of the Davex profile that the belts 2a, 2b and the webs 2c, 2d are joined by a pure crimp connection, namely the webs 2c, 2d are inserted into grooves in the belts 2a, 2b and then crimped.
  • the use of Davex profiles has the advantage that different materials and different material thicknesses can be selected for the belts 2a, 2b and the webs 2c, 2d with the aim of optimizing the load and weight.
  • the profile 2 is connected to the profile 1 by way of its two belt ends 2a *, 2b *, which abut and are welded onto the parallel side wall parts la, lb of the profile 1. While in the embodiment of FIGS. 1 and 2 a weld 3a, 3b is provided on the front edge of the belt ends 2a *, 2b *, in the embodiment of FIGS. 3 and 4 the welds 4a, 4b, 4c are located on the side edges of the belt ends 2a *, 2b *.
  • FIGS. 3 and 4 Another difference between the exemplary embodiment in FIGS. 3 and 4 and FIGS. 1 and 2 is that the webs 2c, 2d reach the profile 1 and are welded to the latter via a weld seam 5.
  • soldered connections or adhesive connections can also be provided, which can be carried out over a large area due to the strong overlap, so that a high rigidity of the node connection can also be achieved thereby.
  • adhesive bonds enable the use of different materials for the profiles that are difficult or impossible to weld, such as aluminum and steel.
  • the node connection according to the invention allows multiple tolerance compensation. On the one hand, tolerance compensation in the axial direction of profile 2 is possible by plugging it more or less onto profile 1. The two exemplary embodiments show this possibility. In addition, the profile 2 can be moved in parallel in the axial direction of the profile 1. Finally, different angles between profiles 1, 2 can also be set.
  • a one-dimensional joining line between the belt ends 2a *, 2b * of one profile 2 and the wall parts la, lb of the other profile 1 can be used to implement a simple and inexpensive, rigid, direct connection of the profiles without the use of additional auxiliary elements , which also takes into account the aspect of lightweight vehicle construction.

Abstract

L'invention vise à réaliser un noeud de raccordement rigide de profilés en tôle d'acier (1, 2), en particulier une structure de cadre d'une carrosserie de véhicule, du type construction légère. L'un des profilés (2) formé de deux bandes parallèles (2a, 2b) et d'au moins une traverse de raccordement (2c, 2d) est inséré, par ses deux extrémités (2a*, 2b*) en saillie par rapport à la barre (2c, 2d), sur l'autre profilé (1) présentant deux éléments de paroi parallèles (1a, 1b), et les extrémités de bande (2a*, 2b*) s'appliquant à plat sur les éléments de paroi (1a, 1b) sont assemblés de manière fixe avec lesdits éléments de paroi (1a, 1b), par exemple, via un raccord par soudure (4a, 4b, 4c). Un tel noeud de raccordement offre une plage compensatoire de tolérance multiple et confère à la structure du cadre une rigidité élevée.
