Light-weight beam assembly and truck trailer using the same
Light-weight beam assembly and truck trailer using the same are disclosed herein. The light-weight beam assembly is a beam being a single unitary continuous piece comprising at least two cutouts cut through, at least one vertically extending supporting member and a plurality of reinforcement members. Two beams may be connected by a plurality of transversal members for use in a truck trailer.
1. A light-weight truck trailer comprising:
two longitudinal beams, each beam being a single unitary continuous piece comprising at least two cutouts cut through the single unitary continuous piece, wherein each of the cutouts independently extend vertically from an upper portion to a lower portion of the beam and extend longitudinally over a length of the beam, and wherein the at least two cutouts are defined within the single unitary continuous piece by at least one vertically extending supporting member;
a plurality of reinforcement members, each reinforcement member being connected to one of the two beams, from one end at the upper portion of the beam and from the other end at the lower portion of the beam so that the reinforcement member extends transversally across one of the cutouts,
wherein at least one of the cutouts extends longitudinally over a length of the beam, from a point at about ¼ to about ⅓ from a front end of the beam, to a point at about ½ to about ⅔ from the front end; and
wherein two reinforcement members overlap at their center to form a x-cross.
2. The truck trailer of claim 1 , wherein the at least two cutouts each independently have the shape of: an ellipse, a circle, a rectangle, a square, a hexagon, or a pentagon.
3. The truck trailer of claim 1 , wherein 2, 3, 4, or 5 large cutouts are present.
4. The truck trailer of claim 3 , wherein at least one of the large cutouts extends longitudinally over a length of the beam, from a point at about ½ to about ⅔ from the front end to a point at about ⅔ to about ¾ from the front end.
5. The truck trailer of claim 3 , wherein at least one of the large cutouts extends longitudinally over a length of the beam, from a point at about ⅕ of the length of the beam from the front end, to a point at about ⅓ of the length of the beam from the front end.
6. The truck trailer of claim 3 , wherein at least one of the large cutouts extend longitudinally over a length of the beam, wherein the length is about ⅙ to about ⅖ of the total length of the beam.
7. The truck trailer of claim 1 , wherein a plurality of small cutouts are present.
8. The truck trailer of claim 1 , wherein a first cutout extends from a point at about ¼ to about ⅓ of the length of the beam from the front end, to a point at about ½ to about ⅔ of the length of the beam from the front end, a secondary cutout may extend from a point at about ½ to about ⅔ of the length of the beam from the front end, to a point at about ⅔ to about ¾ of the length of the beam from the front end and a third cutout may extend from a point at about ⅕ of the length of the beam from the front end, to a point at about ⅓ of the length of the beam from the front end.
9. The truck trailer of claim 1 , wherein a plurality of x-crosses are formed by reinforcement members over the length of at least one cutout.
10. The truck trailer of claim 1 , wherein the beams are formed of steel or aluminum.
11. The truck trailer of claim 1 , wherein the at least one vertically extending supporting member defines an I-shape, a T-shape, a X-shape, or a Y-shape.
12. The truck trailer of claim 1 , wherein the at least one vertically extending supporting member defines an I-shape.
13. The truck trailer of claim 12 , wherein the at least one vertically extending supporting member is positioned, at its center, at a point at about ¼ to about ⅓ of the length of the beam from the front end.
14. The truck trailer of claim 1 , wherein the at least one vertically extending supporting member is positioned, at its center, at a point at about ½ to about ⅔ of the length of the beam from the front end.
15. The truck trailer of claim 1 , wherein the at least one vertically extending supporting member is positioned, at its center, at a point at about ⅔ to about ¾ of the length of the beam from the front end.
16. The truck trailer of claim 1 , wherein a plurality of vertically extending supporting members are present and are each independently positioned, at their respective center, at a point at about ⅕ of the length of the beam from the front end, at a point at about ¼ to about ⅓ of the length of the beam from the front end, at a point at about ½ to about ⅔ of the length of the beam from the front end, and at a point at about ⅔ to about ¾ of the length of the beam from the front end.
17. The truck trailer of claim 1 , wherein the reinforcement members are made of aluminum, stainless steel, steel, carbon fiber, or fiber glass.
18. The truck trailer of claim 1 , wherein the configuration of the two beams are identical.
19. The truck trailer of claim 1 , further comprising a plurality of transversal members, each transversal member being connected:
at one end to the upper portion of one of the two beams and at the other end to the upper portion of the other of the two beams, or
at one end to the lower portion of one of the two beams and at the other end to the lower portion of the other of the two beams.
20. The truck trailer of claim 1 , wherein the total weight of the truck trailer is from about 2000 kg to about 2500 kg.
21. The truck trailer of claim 20 , wherein the total length of the truck trailer is from about 14 m to about 17 m or about 14.6 m to about 16.2 m.
22. The truck trailer of claim 1 , wherein the vertical deformation of the beams receiving a load is from about 2% to about 10%, wherein the load is from about 20,000 kg to about 24,000 kg distributed over a length of from about 500 cm to about 750 cm at the center of the beams.
