Abstract

An assembly is provided consisting of a frame element of a motor vehicle and a connecting element used for connecting a part. The connecting element is secured to the frame element by way of a fiber winding.

First claim

What is claimed is:

1. An assembly, comprising:
a frame element of a motor vehicle;
a connecting element, provided for attaching a component, and
a fiber winding configured to non-displaceably secure the connecting element to the frame element.

2. The assembly as claimed in claim 1 , wherein:
the frame element extends in a longitudinal direction,
the connecting element has an attachment portion, which is configured for attaching the component and extends transversely to the longitudinal direction, and
the fiber winding is configured such that it runs around the attachment portion.

3. The assembly as claimed in claim 2 , wherein the connecting element has an outer surface, on which the fiber winding runs and which is configured such that the outer surface of the connecting element is flush with an outer surface of the frame element.

4. The assembly as claimed in claim 2 , wherein:
the attachment portion is formed from a first sub-element and a second sub-element, which are assembled so as to enclose the frame element, and
the fiber winding is configured such that it runs around the first and second sub-elements of the attachment portion.

5. The assembly as claimed in claim 1 , wherein:
the frame element extends in a longitudinal direction,
the connecting element has a bearing portion, which is adapted to an outer surface of the frame element and from which an attachment portion, for attaching the component, extends transversely to the longitudinal direction, and
the fiber winding is configured such that it runs around the bearing portion and/or the attachment portion.

6. The assembly as claimed in claim 5 , wherein:
the attachment portion extends from a longitudinally directed end portion of the bearing portion, and
the fiber winding is configured such that it runs around the bearing portion and/or the attachment portion.

7. The assembly as claimed in claim 5 , wherein:
the bearing portion is formed from a first sub-element and a second sub-element, which are assembled so as to enclose the frame element, and
the fiber winding is configured such that it runs around the first and second sub-elements of the bearing portion and/or the attachment portion.

8. The assembly as claimed in claim 5 , wherein the connecting element has at least two attachment portions.

9. The assembly as claimed in claim 1 , wherein:
the frame element and the connecting element are formed from a fiber-reinforced plastic, and
the fiber winding is formed from a plastic fiber.

10. The assembly as claimed in claim 1 wherein, in a region on which the fiber winding is formed, the connecting element has concave portions in which to position fiber portions.

11. The assembly as claimed in claim 1 , wherein, in addition to the fiber winding, an integral material bond is formed between the frame element and the connecting element.

12. The assembly as claimed in claim 5 , wherein:
an integral material bond is formed by an adhesive between the frame element and the bearing portion, and,
at at least one end portion of the bearing portion extending in the longitudinal direction away from a longitudinal center of the connecting element, the bearing portion is designed such that a quantity of adhesive increases.

13. A method by which a connecting element provided for attaching a component is secured to a frame element of a motor vehicle, wherein the method comprises the acts of:
providing the frame element and the connecting element; and
securing the connecting element non-displaceably to the frame element via a fiber winding.

14. The method as claimed in claim 13 , wherein:
the frame element extends in a longitudinal direction and the connecting element has an attachment portion, which is configured for attaching the component and, following the securing operation, extends transversely to the longitudinal direction, and
the connecting element is secured to the frame element by the fiber winding formed by a fiber being wound around the attachment portion.

15. The method as claimed in claim 13 , wherein:
the frame element extends in a longitudinal direction,
the connecting element has a bearing portion, which is adapted to an outer surface of the frame element and from which an attachment portion, for attaching the component, extends transversely to the longitudinal direction, and
the connecting element is secured to the frame element by the fiber winding formed by a fiber being wound around the bearing portion and/or the attachment portion.

16. The method as claimed in claim 13 , wherein the fiber winding is formed by a fiber, for securing the connecting element to the frame element, wound such that portions of the fiber run parallel to one another or cross over one another.

17. The method as claimed in claim 14 , wherein the fiber is wound in a direction other than a direction in which the attachment portion extends.

18. The method as claimed in claim 15 , wherein the fiber is wound in a direction other than a direction in which the attachment portion extends.

19. The method as claimed in claim 13 , wherein:
the frame element is designed so as to extend in a longitudinal direction and have an abutment surface, on which the connecting element is brought into abutment with a bearing surface, which corresponds to the abutment surface,
an integral material bond is established between the abutment surface and the bearing surface, and
the fiber winding is formed such that the integral material bond is compressed.

20. The method as claimed in claim 19 , wherein the integral material bond is formed by an adhesive between the abutment surface and the bearing surface such that there is an increase in a quantity of adhesive at at least one longitudinally directed end portion of the connecting element.
