Abstract

A support structure in a framework construction is provided. The support structure includes a first and a second rod of an axle support of a motor vehicle, a positioning element, and a first and a second fiber winding. The positioning element fixes an alignment of the first rod relative to an alignment of the second rod. A first support section of the positioning element is drawn by the first fiber winding in the direction of a support section of the first rod, and a second support section of the positioning element is drawn by the second fiber winding in the direction of a support section of the second rod in order to hold the first and second rods in the fixed alignment relative to each other by a frictional connection.

First claim

What is claimed is:

1. A support structure in a framework construction, comprising:
a first and a second rod of an axle carrier of a motor vehicle,
a positioning element, and
a first and a second fiber winding, wherein
the positioning element defines an orientation of the first rod relative to an orientation of the second rod, and
a first supporting portion of the positioning element is drawn by the first fiber winding in a direction of a supporting portion of the first rod, and a second supporting portion of the positioning element is drawn by the second fiber winding in the direction of a supporting portion of the second rod, in order to secure the first and the second rod in the defined relative orientation to each other via frictional engagement.

2. The support structure as claimed in claim 1 , wherein the first and the second supporting portion of the positioning element have a respective guide device, by which the first and the second fiber winding are respectively guided.

3. The support structure as claimed in claim 1 , wherein the first supporting portion of the positioning element is fastened to the supporting portion of the first rod, and the second supporting portion of the positioning element is fastened to the supporting portion of the second rod, additionally via integrally bonded connections, respectively.

4. The support structure as claimed in claim 3 , wherein the integrally bonded connections are realized by respective adhesives provided between the first supporting portion of the positioning element and the supporting portion of the first rod, and the second supporting portion of the positioning element and the supporting portion of the second rod.

5. The support structure as claimed in claim 4 , wherein a distance between an end portion of the positioning element, which end portion adjoins an exposed portion of the first rod, decreases steadily or incrementally in the direction of another end portion of the positioning element down to a substantially constant value.

6. The support structure as claimed in claim 4 , wherein, adjoining the end portion of the positioning element, a protruding bead of adhesive, is formed.

7. The support structure as claimed in claim 1 , wherein the positioning element is configured as a half-shell, a surface thereof facing the supporting portion of the first rod rests by positive engagement on the supporting portion of the first rod.

8. The support structure as claimed in claim 1 , wherein the positioning element is configured as a tongue, and the first supporting portion and the second supporting portion of the positioning element are connected by a curved portion.

9. The support structure as claimed in claim 1 , wherein the fiber windings comprise at least one fiber, selected from a group of: a carbon fiber, a glass fiber, an aramid fiber and a natural fiber.

10. The support structure as claimed in claim 9 , wherein the at least one fiber is embedded in a matrix material, selected from a group of: a thermoplastic matrix material and a thermosetting matrix material.

11. The support structure as claimed in claim 1 , wherein the first rod and/or the second rod comprise a fiber-reinforced plastic or a metal.

12. The support structure as claimed in claim 1 , wherein the positioning element is formed from a plastic, a fiber-reinforced plastic or from a metal.

13. A method for producing a support structure in a framework construction, the method comprising the acts of:
arranging a first supporting portion of a positioning element on a supporting portion of a first rod of an axle carrier of a motor vehicle;
arranging a second supporting portion of the positioning element on a supporting portion of a second rod of the axle carrier of a motor vehicle;
connecting the first supporting portion of the positioning element to the supporting portion of the first rod by a fiber winding, which draws the first supporting portion of the positioning element in the direction of the supporting portion of the first rod, and connecting the second supporting portion of the positioning element to the supporting portion of the second rod by a second fiber winding, which draws the second supporting portion of the positioning element in the direction of the supporting portion of the second rod, in order to secure the first and the second rod in a defined relative alignment to each other via frictional engagement.

14. The method as claimed in claim 13 , wherein the first and the second supporting portion of the positioning element have a respective guide device, and portions of the first and of the second fiber winding are respectively inserted into the corresponding guide device.

15. The method as claimed in claim 14 , wherein the first supporting portion of the positioning element is fastened to the supporting portion of the first rod, and the second supporting portion of the positioning element is fastened to the supporting portion of the second rod, additionally via integrally bonded connections, respectively.

16. The method as claimed in claim 15 , wherein, for creating the integrally bonded connections, respective adhesives are provided between the first supporting portion of the positioning element and the supporting portion of the first rod, and the second supporting portion of the positioning element and the supporting portion of the second rod.

17. The method as claimed in claim 16 , wherein a distance between an end portion of the positioning element, which end portion adjoins an exposed portion of the first rod, decreases steadily or incrementally in the direction of another end portion of the positioning element down to a substantially constant value.

18. The method as claimed in claim 16 , wherein, adjoining the end portion of the positioning element, a protruding bead of adhesive is formed.

19. The method as claimed in claim 13 , wherein the positioning element is configured as a half-shell, a surface thereof facing the supporting portion of the first rod is placed by positive engagement on the supporting portion of the first rod.

20. The method as claimed in claim 13 , wherein the positioning element is configured as a tongue, and the first supporting portion and the second supporting portion of the positioning element are connected by a curved portion.
