Abstract

A cargo vehicle is disclosed having a composite floor assembly with at least one embedded hardpoint connector. The composite floor assembly may comprise a plurality of transverse beams, wherein a subset of the plurality of transverse beams includes at least one embedded hardpoint connector. The embedded connector may be used to securely and removably couple other vehicle components to the composite floor assembly, such as a landing gear assembly and/or a slide rail assembly.

First claim

What is claimed is:

1. A cargo body, comprising:
a composite floor assembly comprising a plurality of transverse beams;
a first plurality of connectors embedded in the plurality of transverse beams; and
a first longitudinal beam oriented generally orthogonal to the plurality of transverse beams, each of the first plurality of connectors positioned adjacent the longitudinal beam.

2. The cargo body of claim 1 , wherein the first longitudinal beam is positioned laterally inward of a first end and a second end of each of the plurality of transverse beams and each of the first plurality of connectors is positioned laterally between the first longitudinal beam and the first end of the plurality of transverse beams.

3. The cargo body of claim 1 , further comprising a second longitudinal beam oriented generally orthogonal to the plurality of transverse beams and laterally spaced apart from the first longitudinal beam.

4. The cargo body of claim 3 , further comprising second plurality of connectors embedded in the plurality of transverse beams, the second plurality of connectors positioned adjacent the second longitudinal beam.

5. The cargo body of claim 4 , wherein the first and second longitudinal beams are positioned laterally inward of the first and second plurality of connectors.

6. The cargo body of claim 1 , wherein each of the plurality of transverse beams is formed from a core material and an outer skin, and wherein each of the plurality of connectors is embedded in the core material and surrounded by the outer skin of the corresponding beam.

7. The cargo body of claim 1 , wherein a first connector and a second connector are embedded in each of the plurality of beams.

8. The cargo body of claim 1 , wherein the plurality of connectors are spaced longitudinally and laterally apart from one another.

9. A cargo body, comprising:
a composite floor assembly comprising a plurality of transverse beams;
a first plurality of connectors embedded in the plurality of transverse beams; and
a first longitudinal beam oriented generally orthogonal to the plurality of transverse beams, each of the first plurality of connectors positioned adjacent the longitudinal beam;
wherein the first longitudinal beam includes a core material extending along a longitudinal length of the first longitudinal beam, the first plurality of connectors being laterally offset from the core material of the first longitudinal beam.

10. The cargo body of claim 9 , wherein the first longitudinal beam further includes an outer skin surrounding at least a portion of the core material and the plurality of connectors are aligned with the outer skin.

11. A cargo body, comprising:
a composite floor assembly comprising a plurality of transverse beams;
a plurality of connectors embedded in the composite floor assembly; and
a landing gear assembly coupled to the plurality of connectors using a plurality of mechanical fasteners.

12. The cargo body of claim 11 , wherein the composite floor assembly comprises a plurality of transverse beams and each of the plurality of connectors is embedded in a corresponding one of the plurality of transverse beams.

13. The cargo body of claim 11 , further comprising:
a longitudinal beam coupled to the plurality of connectors, the plurality of connectors positioned laterally intermediate the longitudinal beam and an outer perimeter of the composite floor assembly.

14. The cargo body of claim 11 , wherein:
the plurality of connectors includes a left connector embedded in a left side of the composite floor assembly and a right connector embedded in a right side of the composite floor assembly;
the landing gear assembly includes a left mounting bracket aligned with and fastened to the left connector and a right mounting bracket aligned with and fastened to the right connector.

15. The cargo body of claim 14 , wherein:
the left mounting bracket is T-shaped with a vertical portion and a horizontal portion, the horizontal portion defining apertures aligned with the left connector on either side of the vertical portion; and
the right mounting bracket is T-shaped with a vertical portion and a horizontal portion, the horizontal portion defining apertures aligned with the right connector on either side of the vertical portion.

16. The cargo body of claim 14 , further comprising:
a left reinforcing layer positioned between the left mounting bracket and the left connector; and
a right reinforcing layer positioned between the right mounting bracket and the right connector.

17. A cargo body, comprising:
a composite floor assembly;
a plurality of connectors embedded in the composite floor assembly;
a landing gear assembly coupled to the plurality of connectors using a plurality of mechanical fasteners; and
a longitudinal beam coupled to the plurality of connectors, the plurality of connectors positioned laterally intermediate the longitudinal beam and an outer perimeter of the composite floor assembly;
wherein in the landing gear assembly is further adhered to the longitudinal beam.

18. A cargo body, comprising:
a composite floor assembly including a plurality of beams;
a plurality of connectors embedded in the plurality of beams; and
a slide rail assembly coupled to the plurality of connectors using a plurality of mechanical fasteners.

19. The cargo body of claim 18 , wherein the plurality of beams are oriented generally orthogonal to a longitudinal axis of the composite floor assembly.

20. The cargo body of claim 18 , wherein a first connector and a second connector are embedded in each of the plurality of beams.

21. A method of manufacturing a composite floor assembly with at least one embedded connector, the method comprising:
positioning at least a first connector and a second connector in an outer skin, the second connector spaced apart from the first connector;
introducing an expandable core material into the outer skin;
expanding the core material around the at least first and second connectors in the outer skin to form a composite beam with the at least the first and second connectors embedded therein; and
arranging the composite beam with a plurality of additional composite beams to form a composite floor assembly.

22. The method of claim 21 , wherein the expandable core material is a foam.

23. The method of claim 21 , wherein the arranging step comprises arranging the plurality of additional composite beams transversely across an inner portion of the composite floor assembly.
