Definitions

  • the invention relates to a component connection according to the preamble of claim 1.
  • first and second components are connected in such a way that one of the component at least partially and positively engages around the other and the first and second components are at least partially non-positively connected in this coverage area, it is ensured that the component connection in a simple manner and cost can be produced and at the same time high forces and moments can be transmitted by means of this connection.
  • the positive connection of the components in the covering area by folding and the at least partially non-positive connection is realized by embossing.
  • Such connection methods are technically mature and widely used, so that their implementation is also possible from a cost point of view with reasonable effort.
  • the load capacity of the component connection can also be increased by the fact that the first and second components to be joined experience a common deformation caused by folding, defining the positive connection of the connection.
  • the component connection can also be designed so that only the edge zones of the covering region have impressions. This reduces in particular the manufacturing costs of the component connection.
  • the interconnected components in the covering area can also be continuously penetrated by indentations. Because of the more uniform loading of the interconnected components in particular reduces their load-dependent wear.
  • the structure of the embossments introduced in the overlapping area can be designed as desired. This creates the possibility that the connection of the components as a whole can be adapted very precisely to local load peaks. In addition to a reduction in manufacturing costs, this also leads to optimally adapted to the loads occurring component structures.
  • simply structured production tools can then be used when so-called connecting webs are assigned to the components to be connected in the region of the connection to be formed, which can be grasped by the deformation tools in a simple manner.
  • the invention is provided in an advantageous development that the indentations are introduced into the interconnected components in such a way that they cover the covering area from the free end of the respective Enforce connecting webs to the fixed end of these connecting webs.
  • FIG. 1 shows the component connection 1 according to the invention in a schematic illustration using the example of a support profile 4 consisting of a first component 2 and a further component 3. It is within the scope of the invention that the support profile 4 be used in a wide variety of fields, such as vehicle axle construction or manufacturing of structures can be used per se.
  • the substantially trough-shaped first and second components 2, 3 are formed in their contact area 5 flange-shaped connecting webs 6, 7.
  • the flange-shaped connecting webs 6 of the first component 2 have approximately horizontally away from the first component 2 while the further component 3 integrally formed flange-shaped connecting webs 7 each engage around the connecting webs 6 of the first component 2.
  • this encompassing of the connecting webs 6 of the first component 2 is achieved in that the connecting webs 7 of the further component 3 are bent by folding so that they embrace the flange-shaped connecting webs 6 of the first component 2 substantially form fit. It is within the scope of the invention that the mutually contacting connecting webs 6, 7 of the respective components 2, 3 can be brought together by folding initially in a positive connection.
  • this covering area 8 formed by folding the respective connecting webs 6, 7 is penetrated by indentations 9, which at the same time realizes a further connection between the respective components 2, 3 caused essentially by adhesion in the covering area 8 in addition to the form-fitting connection caused by the folding.
  • the impressions 9 introduced into the covering area 8, as shown in FIG. 2 can be introduced by movable embossing tools 10.
  • the embossing of the components 2, 3 succeed in such a way that the connecting webs 6, 7 of the respective components 2, 3, which are previously positively connected by folding, are fixed in workpiece counter holders 11, the workpiece counterpart 11 being in the region of the indentations 9 to be formed Recesses 12, into which the deformed by the embossing tools 10 material of the connecting webs 6, 7 can escape when penetrating the tools 10 in the connecting webs 6, 7.
  • both a positive and positive connection of the respective components 2, 3 is achieved, which ultimately enables the transmission of higher forces and moments in the overlap region 8 of the respective components 2, 3.
  • the embossing tools 10 can be arranged so that 8 indentations 9 are introduced only in the edge regions of the overlap region. In cases where the burdens of connected components 2, 3 is substantially equal over their entire length, the indentations 9 can extend over the entire overlap region 8 and at approximately the same distance from each other.
  • the indentations 9 can also have different cross sections. In the simplest case, this can be achieved in that the embossing tools 10 are of different shape. So that the impressions 9 to be introduced into the components 2, 3 after folding by means of the embossing tools 10 do not damage the positive connection achieved by the folding, the embossing tools 10 are formed by the at least one free end 13 of the connecting webs 6, 7 formed on the components 2, 3 to the at least one fixed end 14 of the respective connecting web 6, 7 guided by the overlapping region 8, so that the indentations 9 in the region of the free ends 13 have their depressions and in the region of the fixed ends 14 their material elevations.
  • the embossing tools 10 in principle on both sides of the overlap region 8, the respective connecting webs 6, 7 penetrate.
