Definitions

  • Carrier structure composed of carriers formed by hollow profiles for the body of a motor vehicle
  • the invention relates to a support structure composed of supports formed by hollow profiles for the body of a motor vehicle with at least one functional module fastened to one of the supports, which has a base part for a functional element of the motor vehicle supported by this base part, the one support at the fastening location of the functional module having a recess and the base part is designed as a support part which complements the support in the region of its recess and is adapted to the sheet metal profile for this purpose.
  • the aim is on the one hand to keep the weight as low as possible and on the other hand to produce them as cost-effectively as possible.
  • a light weight is achieved through the selection of the materials used and load-optimized parts, while cost-effective production is achieved through the use of functional modules (modular design).
  • “Function modules” are simply understood to mean basic parts to be connected to the supporting structure, the axle stool or Carry axle modules, if necessary with handlebars attached to them.
  • Other pre-assembled functional elements of the motor vehicle can also be parts of such a functional module.
  • this modular design has the disadvantage that the base part means additional weight on the one hand and on the other hand unnecessarily reinforces the support in the area of application, even negatively changing its desired crash behavior.
  • Support structures for the body of a motor vehicle of the type mentioned at the outset are composed of supports formed by hollow profiles (DE 40 14 385 AI).
  • the supports consist of extruded hollow profiles made of aluminum.
  • a problem with such extruded hollow profiles that are constant in the wall thickness over the entire length is that the wall thickness is insufficient in the areas where functional elements are to be attached. This means that the extruded profile should have a greater wall thickness over its entire length, which would lead to an undesirable increase in weight in motor vehicle bodies.
  • Another difficulty is that a special shape in the hollow profile would normally have to be provided for the functional elements.
  • a functional module in the form of a light metal casting with the desired shape is welded into a recess in the extruded hollow profile created for this purpose.
  • the invention has for its object to provide a support structure for car bodies of motor vehicles, which is both weight and load optimized and requires little manufacturing effort with respect to various functional elements of the motor vehicle.
  • Load-optimized means that the load optimization is not disturbed in the area of the functional elements.
  • the base part is an integral part of the support, which in particular serves as a longitudinal support.
  • the material doubling associated with the connection of the base part to the carrier of the support structure in the prior art, which disadvantageously shortens the crash zone in front of and behind the passenger compartment, in particular in the case of a side member, does not occur in the invention because the base part is for energy absorption can be used for major crashes.
  • the inserted base part can have different moments of resistance along its length. In particular, it can have a different sheet thickness over its length and / or have predetermined bending points.
  • the base part can be connected to the carrier using the usual joining techniques, such as welding, gluing or by means of a rivet-screw connection. Combined joining techniques are also conceivable.
  • the adhesive connection can serve as a cushioning intermediate layer with the appropriate adhesive.
  • Thick-film adhesives such as those e.g. can be used to attach the front windows.
  • a mechanical fastening such as a screw connection, should be used as an additional safeguard, which, however, is then also used to maintain the damping effect, e.g. should be vibration decoupled by rubber pads.
  • the functional module is preferably arranged outside of selected crash zones. It can also be designed for different moments of resistance over its length due to different dimensions and predetermined kinks.
  • the base part consists of a hat profile enclosing the adjacent ends of the recessed carrier. A plate fastened to the flanges of the hat profile is used to close the hat profile. This plate is preferably formed by the sheet metal field of the body, for example by the base plate of the body.
  • Fig. 1 shows a support structure in detail in
  • FIG. 4 shows the support structure according to FIG. 1 in different half-sections of FIG. 3,
  • FIG. 5 shows the support structure according to FIG. 1 in an enlarged half-section B2-B2 of FIG. 3
  • 6 shows the functional module for a support structure according to FIG. 1 in pairs in a perspective view
  • Fig. 8 is a support structure in side view in
  • FIG. 9 shows the support structure according to FIG. 1 in
  • the support structure shown in FIGS. 1 and 2 in detail and side view comprises a longitudinal beam 1 with a column 2 attached to it, which is the C-column.
  • Sheet metal panels 3, 4, 5 rest on the side member 2, for example the trunk plate 3, the base plate 4 and the inner wheel arch 5.
  • the side member 1 can be a single-chamber profile in accordance with the exemplary embodiment in FIGS. 1 to 7 or in accordance with the exemplary embodiment in FIG Two-chamber profile should be formed.
  • the supports consist of sheet metal plates that are longitudinally welded.
  • the carrier 1 has a recess in an area where functional elements are to be attached.
  • a base part 6, which complements the recess, is inserted between the remaining sections 1 a, 1 b
  • the base part 6 consists of sheet metal and is designed as a hat profile. Its profile is adapted to the profile of the remaining sections la, lb of the carrier 1 in such a way that it overlaps the carrier 1. It is closed at the top by a plate that is firmly connected to its outward-facing flanges.
  • the plate can be part of a sheet metal field 3 and or 5, e.g. the bottom plate of the trunk and / or the wheel arch.
  • a particularly damping welded connection, a screw connection or an adhesive connection or combinations thereof can be used as connection techniques for the area overlapping with the sections la, lb of the carrier 1 and for the closing plate 3.
  • the adhesive technology has been used.
  • the adhesive 6a is designed as a damping intermediate layer 6a. Screw connections can also be provided in the area of the flanges.
  • the hat-shaped profiled base part 6 can be designed differently in accordance with the exemplary embodiments in FIG. 7. Instead of a constant sheet thickness over its entire length, it can have different thicknesses in the longitudinal direction according to the tailored blanks method. It has graded according to the versions a and b different thicknesses, while according to the embodiment d the thickness decreases continuously.
  • predetermined kinks are provided by impressions. Such dimensions can be used to specify where the deformation in the event of a crash preferably takes place along the length of the base part.
  • FIG. 9 shows, in the case of a slight crash, only a deformation takes place in the section 1b, while in the case of a severe crash, there is also a deformation in the base part 6, specifically with a dimensioning corresponding to FIG. 7b with that in the wall thickness thinnest section in the middle targeted in the middle area.
  • the section 1b of the carrier needs to be replaced, while in the event of a serious crash both this section 1b and the functional module with the base part 6 have to be replaced.
  • FIG. 9 shows, can be achieved by appropriate dimensioning of the end portion 1b of the carrier 1 and the functional module, namely the base part 6, that in the event of a crash the passenger compartment is largely protected from deformation and the carrier 1 with the functional module is easy to repair in that, in the event of a slight crash, the deformation is limited to the comparatively simple carrier section 1b, while the more complex structure of the functional module 6 only has to be replaced in the event of more severe crashes.
  • the embodiment of FIG. 8 differs from that of FIGS. 1 to 7 and 9 only in that the carrier consists of two sheet metal profiles 10a, 10b arranged one above the other and connected to one another. In such a case, the recess is provided at the end of a sheet profile 10b.
  • a base part 11 of the functional module is designed as a hollow chamber profile and has one end overlapping on the sheet metal profile 10a and in the remaining area is attached flat to the profile 10a and optionally additionally fastened by means of screw connections.
  • the section of the sheet metal profile 10a projecting from the functional module alone forms the crash zone for light crashes.
  • the crash zone for more severe crashes is formed by the adjoining section of the sheet metal profile 10a and by the base part 11 of the functional module.
