Fastening assembly for mounting components and off-road utility vehicle having a fastening assembly

1. A fastening assembly, comprising:

a vehicle frame for at least one component part to be fastened to said vehicle frame, said vehicle frame having first and second internal surfaces and a first closed cross-sectional profile;

at least one carrier having an opening for carrying a fastening device, said at least one carrier extending from said first internal surface to at least said second internal surface, said at least one carrier extending through and beyond the component part, and said at least one carrier having a closed second cross-sectional profile;

a fastening element passing through said at least one carrier element, said fastening element crushing said at least one carrier element and forcing a contact surface of the component part tightly against said frame;

said vehicle frame and said at least one carrier having at least one of a watertight or gastight connection for sealing said first cross-sectional profile and an interior of said vehicle frame to an outside of said vehicle frame.

2. The fastening assembly according to claim 1 , wherein said first and second internal surfaces of said vehicle frame are oriented parallel to each other.

3. The fastening assembly according to claim 1 , wherein said first and second internal surfaces of said vehicle frame form an angle with each other not exceeding ±90°.

4. The fastening assembly according to claim 1 , wherein said at least one carrier and said vehicle frame are manufactured from different materials.

5. The fastening assembly according to claim 1 , wherein said at least one carrier and said vehicle frame are connected to one another or sealed by a pressed connection, a welded connection or an adhesive bond.

6. An off-road utility vehicle, comprising:

at least one fastening assembly according to claim 1 ; said vehicle frame of said at least one fastening assembly being a closed cross-sectional profile.

7. The fastening assembly according to claim 1 , wherein said vehicle frame has an external side beyond which said at least one carrier projects.

8. The fastening assembly according to claim 1 , wherein said watertight or gastight connection is a weld provided inside said frame.

9. A fastening assembly, comprising:

a vehicle frame for at least one component part to be fastened to said vehicle frame, said vehicle frame having first and second internal surfaces and a first closed cross-sectional profile;

at least one carrier having an opening for carrying a fastening device, said at least one carrier extending from said first internal surface to at least said second internal surface, said at least one carrier extending through and beyond the component part, and said at least one carrier having a closed second cross-sectional profile;

a fastening element passing through said at least one carrier element, said fastening element crushing said at least one carrier element and forcing a contact surface of the component part tightly against said frame; and

said vehicle frame and said at least one carrier having at least one of a watertight or gastight connection for sealing said first cross-sectional profile and an interior of said vehicle frame to an outside of said vehicle frame, said vehicle frame has an external side beyond which said at least one carrier projects.

10. The fastening assembly according to claim 9 , wherein said watertight or gastight connection is a weld provided inside said frame.

11. A fastening assembly, comprising:

a vehicle frame having first and second internal surfaces and a first closed cross-sectional profile, said closed cross-sectional profile providing said vehicle frame with a high torsional rigidity sufficient for a heavily stressed vehicle;

at least one component part for being mounted on said vehicle frame;

at least one carrier having an opening for carrying a fastening device, said at least one carrier extending from said first internal surface to at least said second internal surface, said at least one carrier extending through and beyond the component part, and said at least one carrier having a closed second cross-sectional profile;

a fastening element passing through said at least one carrier element, said fastening element crushing said at least one carrier element and forcing a contact surface of the component part tightly against said frame; and

said vehicle frame and said at least one carrier having a fluid tight connection for sealing said first cross-sectional profile and an interior of said vehicle frame to an outside of said vehicle frame.

12. The fastening assembly according to claim 11 , wherein said heavily stressed vehicle is a military vehicle, construction vehicle, or off-road vehicle.

13. The fastening assembly according to claim 11 , wherein said watertight or gastight connection is a weld provided inside said frame.
