Abstract

The invention relates to a shell structure having a force transmission point, wherein a force transmission structure is provided on the force transmission point, wherein the force transmission structure has a fitting element comprising a fastening element, wherein the fitting element is connected to the shell structure. According to the invention, the fitting element has a contact surface having the shell structure and the contact surface can be clamped with or is clamped with the shell structure.

First claim

What is claimed is:

1. A shell structure apparatus, comprising:
a shell structure having a force transmission point, the shell structure coupled to a force transmission structure at the force transmission point so as to guide forces into the shell structure,
wherein the force transmission structure has a fitting part with a fastening element, by way of which force is guided into the force transmission structure,
wherein the fitting part is connected with the shell structure,
wherein the fitting part is defined by a first side having a contact surface with the shell structure and the contact surface is configured to be braced with the shell structure,
wherein an entirety of the first side of the fitting part is one of directly pressed against the shell structure or in adhesive contact with the shell structure.

2. The shell structure apparatus according to claim 1 , wherein the shell structure is produced of one of glass fiber-reinforced plastic and carbon fiber-reinforced plastic.

3. The shell structure apparatus according to claim 1 , wherein the fitting part is made of one of iron, steel, aluminum and an alloy thereof.

4. The shell structure apparatus according to claim 1 , wherein the fitting part is one of a sheet-metal-shaped component, a plate-shaped component and a disk-shaped component, and wherein the contact surface is formed by cold forming or cranking.

5. The shell structure apparatus according to claim 1 , wherein the fitting part is glued to the shell structure, the contact surface being free of adhesive.

6. The shell structure apparatus according to claim 1 , wherein one of the fitting part or the shell structure includes a jutting-back surface that juts back from the contact surface, the jutting-back surface configured for a glued connection with the shell structure.

7. The shell structure apparatus according to claim 2 , wherein one of the fitting part or the shell structure includes a jutting-back surface that juts back from the contact surface, the jutting-back surface configured for a glued connection with the shell structure.

8. The shell structure apparatus according to claim 6 , wherein the jutting-back surface forms a gap with a surface of the shell structure opposite the jutting-back surface at least in the area of the glued connection, which gap at least essentially has a uniform distance.

9. The shell structure apparatus according to claim 7 , wherein the jutting-back surface forms a gap with a surface of the shell structure opposite the jutting-back surface at least in the area of the glued connection, which gap at least essentially has a uniform distance.

10. The shell structure apparatus according to claim 1 , wherein the contact surface is at least essentially plane.

11. The shell structure apparatus according to claim 1 , wherein the fastening element is configured to fastening a load absorption element for the absorption of an external load, the absorption of the load at the load absorption element taking place on a side of the shell structure which is situated opposite that side at which the fitting part is connected with the shell structure.

12. The shell structure apparatus according to claim 1 , wherein the contact surface is braced by way of the fastening element with a surface of the shell structure, the fastening element having a threaded element which is provided at the fitting part.

13. The shell structure apparatus according to claim 12 , wherein, from a side of the fitting part situated opposite the contact surface, the threaded element is fastened to the fitting part and pressed into a through hole constructed in the fitting part.

14. The shell structure apparatus according to claim 12 , wherein the threaded element has one of a nut thread that does not project beyond the contact surface, and a bolt part preferably projects through an opening in the shell structure.

15. The shell structure apparatus according to claim 13 , wherein the threaded element has one of a nut thread that does not project beyond the contact surface, and a bolt part preferably projects through an opening in the shell structure.

16. The shell structure apparatus according to claim 1 , wherein the fastening element has a press nut which, from a side of the fitting part situated opposite the contact surface, is pressed into a through hole constructed in a section of the fitting part corresponding to the contact surface, and which does not project beyond the contact surface, wherein, by means of a screw, which is to be guided through an opening in the shell structure into the press nut, wherein the contact surface is configured to be braced with the shell structure, and wherein, simultaneously a load absorption element for absorbing an external load is configured to be fixed by the screw on a side of the shell structure situated opposite the fitting part.

17. The shell structure apparatus according to claim 1 , wherein a covering is configured to cover the fitting part, the covering being glued to the shell structure in a circumferential manner.

18. The shell structure apparatus according to claim 1 , wherein the shell structure is a body part of a motor vehicle.
