Abstract

A method is provided for connecting a first component to a second component. The two components are placed against each other and pre-fixed, wherein the two components are attached and immovably connected to each other at at least one first connection point via a first detachable component connection and are attached and connected to each other so as to be movable relative to each other in a sliding direction at at least one second connection point via a second detachable component connection. The pre-fixed components are rigidly connected, in particular, by welding.

First claim

What is claimed is:

1. A method for connecting a first connection component to a second connection component, the method comprising the acts of:
placing the first and second connection components against each other;
pre-fixing the first and second connection components together, wherein the connection components are attached and non-movably connected to each other at at least one first connection point via a first detachable component connection, and are attached and connected to each other so as to be movable relative to each other in a sliding direction at at least one second connection point via a second detachable component connection; and
rigidly connecting the pre-fixed first and second connection components together,
wherein at least one of the two components connections is produced by:
insertion of a male fixing element into a female fixing element in an insertion direction, wherein:
the male fixing element is spaced apart from one of the two connection components and has a sphere or sphere-like shape, the male fixing element being a separate part from the connection components and being connected to said one of the two connection components in a material-locking manner, and
the female fixing element is included on the other one of the two connection components and receives the male fixing element, a clamp connection of the fixing elements being produced by the inserting of the male fixing element into the female fixing element in the insertion direction,

wherein the second component connection is operatively configured such that heat stress occurring during the rigid connection is compensated in the sliding direction.

2. The method according to claim 1 , wherein the act of rigidly connecting further comprises the act of welding the pre-fixed first and second connection components together.

3. The method according to claim 1 , wherein the connection components are vehicle components.

4. The method according to claim 1 , wherein the act of rigidly connecting further comprises the act of generating, via welding, a longitudinal welded seam substantially parallel and coaxial to the sliding direction.

5. The method according to claim 2 , wherein the welding is carried out via a focused laser beam.

6. The method according to claim 1 , wherein the male fixing element is over sized relative to the female fixing element substantially perpendicular to the insertion direction, wherein the two connection components are clamped together on the fixing elements.

7. The method according to claim 1 , wherein the female fixing element comprises a passage hole formed in the second connection component.

8. The method according to claim 6 , wherein the female fixing element comprises a passage hole formed in the second connection component.

9. The method according to claim 8 , wherein the passage hole has a non-circular shape.

10. The method according to claim 9 , wherein the passage hole has a polygonal shape.

11. The method according to claim 10 , wherein the polygonal shape is at least one of a triangle, rectangle and square.

12. The method according to claim 1 , wherein the two connection components are fixed in a region of the fixing elements in a manner prohibiting sliding relative to one another in directions perpendicular to the insertion direction.

13. The method according to claim 1 , wherein the female fixing element is a slot and/or an oblong passage hole in which an assigned male fixing element is slidable in a longitudinal direction of the slot and/or the oblong passage hole.

14. The method according to claim 7 , further comprising the act of exerting a clamping force onto an outer side of the male fixing element from the outside inward and substantially perpendicular to the insertion direction via at least one clamp element capable of elastic bending that is included at a distance from the second connection component on an edge of the passage hole.

15. The method according to claim 14 , wherein the clamp element grips the assigned male fixing element from behind to form a positive-fit.

16. The method according to claim 14 , wherein the clamp element is a clamp collar extending along substantially an entire edge of the passage hole.

17. The method according to claim 14 , wherein the clamp element comprises multiple clamp collars along an edge of the passage hole, the multiple clamp collars being spaced apart from one other along a periphery and abut against the male fixing element from the outside inward along a section of the periphery.

18. The method according to claim 14 , wherein the clamp element comprises one or more clamp collars that project from the second connection component in an insertion direction.

19. The method according to claim 1 , wherein at least one of the first and second connection components is a vehicle sheet metal component.

20. The method according to claim 1 , wherein at least one of the first and second connection components is a vehicle body component.

21. The method according to claim 7 , wherein the passage hole is formed by stamping the passage hole out of the second connection component.

22. The method according to claim 16 , wherein the clamp collar is a bent section of the second connection component.

23. The method according to claim 1 , wherein the male fixing element comprises only metal.

24. The method according to claim 1 , wherein the male fixing element is welded onto the first connection component.
