Embodiment Construction

[0062] body in figure 1 and 2 The load-bearing structure 1 of the vehicle body shown in , comprises a passenger compartment section 1 a , a front section 1 b and a rear section 1 c and is constructed by means of a plurality of load-bearing structures. In addition, under the figure 1 and 2 A door has been installed in the body load-bearing structure 1 of the Figures 3 to 7 is no longer shown.

[0063] The vehicle body load-bearing structure 1 includes a floor assembly 10 , a front compartment 20 , a floor rear 40 , a storage compartment 50 and side elements 70 a and 70 b as a load-bearing structure.

[0064] The load-bearing structure is a surface-loaded structure extending in all spatial directions, ie in all three vehicle directions x-, y- and z-direction, which is composed of surface elements and is itself self-supporting and thus holds The load is distributed / distributed in all spatial directions. By means of such a load-bearing structure, the usual joints connecting...

Abstract

The invention relates to a body supporting structure (1) for a vehicle body having a passenger-compartment section (1a), a front-structure section (1b) and a rear-part section (1c); according to the invention, it is provided that, in order to form the body supporting structure (1), at least one supporting-structure body (10, 20, 40, 50, 70) is configured as a three-dimensional flat structure which extends in all vehicle directions (x, y, z direction) and comprises flat elements, the flat elements which extend in different vehicle directions (x, y, z direction) are connected with the formation of soft transitions, the flat elements are configured with cross-sectional areas which are structured depending on the applications of load which occur, and flat elements with low applications of load or non-supporting regions are configured with apertures.

Description

technical field [0001] The invention relates to a body support structure for a motor vehicle body, having a passenger compartment section, a front section and a rear section. Background technique [0002] The existing technology for the production of car bodies has long been the self-supporting car body in the form of a shell structure, in which profiles, frame parts, reinforcements, sheet parts and cladding panels as steel elements and sheet elements are combined with different connection technologies The / shell parts are non-detachably connected to each other and form the body support structure. So-called bodyshell designs, which are mainly used in motorsport, also belong to this type. In this case, the monocoque shell, for example, forms the load-bearing structure of the vehicle, ie the cockpit is produced in this shell construction as a shell shell and is connected to the body. [0003] The applicant introduced a new concept in the body structure as a lightweight cons...
