Definitions

  • the invention relates to a body for a motor vehicle of the type specified in the preamble of claim 1.
  • Such a body is already known as known from DE 35 40 814 C2, which comprises a support structure with a roof module placed on a basic module.
  • B-pillars are assigned to the roof module, which are attached to the roof module and extend between the roof of the roof module and the basic module.
  • the roof pillars are to be fixed with their respective lower ends to the basic module, with the roof pillars being attached to mounting profiles on side longitudinal members and fastened for this purpose.
  • the invention has for its object to provide a body of the type mentioned with a different type of modularization and with improved crash stability.
  • the roof pillar is designed as a separate component, as a result of which the roof module and the roof pillars can be easily connected to one another or to the basic module in terms of production technology when assembling the modules. Due to the overlapping fastening of the upper end of the roof pillar to the support part projecting from the roof, an extremely stable fastening is achieved, for example, against a side impact on the assembled body. In addition, the overlapping arrangement of the two components makes it very stable and suitable for series vehicle construction easily reproducible attachment by a joint connection or a mechanical connection or the like. be created.
  • the roof pillar is attached to the support part from the outside and the support part acts as a tie rod for the upper end of the roof pillar.
  • a particularly good fixation of the upper end of the roof pillar on the roof module is obtained if the support part is fixed to a lateral roof spar of the roof module. If the roof pillar comprises at its upper end a contact section, by means of which the roof pillar is supported from the outside against the roof spar, an additional stable overlap of the roof pillar with the roof spar is created in addition to the overlap with the support part.
  • the arrangement of the contact section within a recess in the roof pillar ensures, on the one hand, a particularly stable fastening of the roof pillar to the roof pillar and, on the other hand, the contact section can be integrated flush in the roof pillar.
  • a particularly good fastening of the lower end of the roof pillar to the side longitudinal member of the basic module is provided if the roof pillar ends at the lower end at a fastening profile which runs installed in the direction of extension of the side longitudinal member, this fastening profile preferably being essentially U-shaped in cross section and can be plugged onto the side longitudinal beam essentially in a form-fitting manner. Since the roof pillar can be mounted at the lower and upper ends in two different fastening directions, namely at the lower end from above and at the upper end from the outside towards the center of the vehicle, a very stable arrangement of the roof pillar on the support structure is achieved. In addition, a simple, easily reproducible assembly of the roof pillar by plugging of the lower end and then setting the upper end.
  • Fig.l is an exploded perspective view of the support structure of the motor vehicle body according to the invention composed of large-sized sub-modules;
  • FIG. 2 shows a further perspective exploded view of the support structure composed of sub-modules, which is clad with outer paneling parts;
  • FIG 3 shows a perspective view of a roof module, on which support parts are provided for fixing the B-pillars.
  • FIG. 4 shows a perspective view of the roof pillar which can be fixed on the roof module and on the basic module;
  • FIG 5 shows an enlarged partial side view from the interior of the body on the fastening of the upper end of the roof pillar to the support part of the roof module.
  • Fig.l is a perspective exploded view of a support structure 10 of a motor vehicle body is shown, which is composed of several large-sized sub-modules described in more detail below.
  • the sub-modules of the support structure 10 are each produced from a plurality of sheet metal parts joined together;
  • the sub-modules can also in other designs, for example as a so-called space frame, as plastic parts, metal castings, as components in a so-called sandwich construction or the like. be prefabricated.
  • combinations of different designs for the assembled sub-modules are also conceivable depending on the application and load.
  • the individual modules are connected in particular via adhesive connections, welded connections or other common connections such as screw connections or the like.
  • a basic module 12 of the support structure 10 essentially comprises a body floor 14 which is laterally delimited by side members 16. To the front, the basic module 12 extends to column sections 18 of front wall columns, which protrude upward from the respectively assigned front ends of the side longitudinal members 16. The body floor 14 of the basic module 12 ends at a considerable distance behind the front end of the basic module 12 or behind the column sections 18 of the front wall columns. At the rear, the basic module 12 ends behind rear wheel arches 22, above which wall areas 24 of the respective rear side wall are arranged. The basic module 12 is equipped as far as possible with the other sub-modules before being assembled.
  • a front module 26 is connected to the basic module 12, which belongs to the front crumple zone of the motor vehicle and is supported on the basic module 12 in a crash-stable manner.
  • the front module 26 comprises a front end region 28 of the body floor 14, which extends between lateral longitudinal beam sections 30 of the front module 26.
  • the front end region 28 of the body floor 14 ends at a front end wall 32 of the passenger compartment, which extends from the front end region 28 of the body floor 14 to approximately the level of the side wall edge of the support structure 10.
  • the end wall 32 is delimited by column sections 34 of the front wall columns, which protrude upward from the lateral longitudinal beam sections 30 of the front module 26.
  • front side members 36 are recognizable.
  • the front module 40 is followed by a front module 40, which is partially shown in FIG. 2 and includes, for example, the front bumper.
  • a roof module 42 which can be seen in conjunction with FIG. 3, can be placed on the basic module 12 and the front module 26, which here comprises lateral A-pillars 44, lateral roof bars 46 in the region of the roof 43, and C-pillars 48.
  • the lower ends of the A-pillars 44 and the C-pillars 48 are each connected to one another via a cross member element 51.
  • the A-pillars 44 are supported on the basic module 12 and on the front module 26.
  • the lower ends of the C-pillars 48 are supported on the respectively assigned upper end of the wall areas 24, the modules 12, 42 being connected to one another, for example, by means of an adhesive connection.
  • the basic module 12 is followed by a rear module 52, which, when the support structure 10 is assembled, belongs together with the rear end region of the basic module 12 to the rear crumple zone of the motor vehicle and limits the rear of a trunk.
  • the rear module 52 is followed by a rear end module with a rear bumper 54, which can be seen in FIG.
  • roof pillar 50 is formed as a separate component and when assembling the sub-modules 12,26, 42, 50, 52 in a manner which will be explained in more detail below, with their upper end 60 overlapping on a support part 62 projecting from the roof rail 46 of the roof 43 and with their lower end 64 on the basic module 12.

Abstract

L'invention concerne une carrosserie de voiture dont la structure portante (10) comporte un module de toit (42) posé sur un module de base (12), un montant (50) s'étendant entre le toit (43) du module de toit (42) et le module de base (12). Lors de l'assemblage des modules (12,26,42,50,52), l'extrémité inférieure (64) de ce montant est fixée sur le module de base (12). L'invention vise à modulariser différemment la structure portante (10) et à améliorer la résistance de la carrosserie contre les impacts. A cet effet, le montant (50) est un élément séparé dont l'extrémité supérieure (60) se fixe en superposition sur un élément support (62) dans le prolongement du toit (43).
