Abstract

A vehicle body construction method is provided for connecting two components which are to be rigidly connected to one another. A first component is provided on which a first positive-fit element projects away from the first component. A second component is provided, which includes a second positive-fit element which cooperates with the first positive-fit element of the first component. The two components are detachably fixed by placing them against one another such that the positive-fit elements mesh with or latchingly engage one another. The components are held relative to one another at least in one direction and are permanently connected by use of an adhesive that is located between mutually facing surfaces of the two components.

First claim

What is claimed is:

1. A method for fixedly connecting two components to one another, the method comprising the acts of:
providing a first component having a first positive-fit element projecting away from a surface of the first component, the first positive-fit element being a separate sphere-shaped component welded to the first component;
providing a second component having a second positive-fit element operatively configured to interact with the first positive-fit element of the first component, the second positive-fit element being a through-hole in the second component having one or more gripping collars projecting away from the through-hole in the second component;
detachably fixing the first and second components together by arranging the first and second components on one another such that the first and second positive-fit elements engage one another to hold the first and second components relative to one another at least in one direction, wherein an undercut is formed below the one or more gripping collars and underneath the sphere-shaped component;
supplying a glue between mutually facing surfaces of the first and second components to form a long-term connection of the first and second components, the glue filling up completely the entire undercut upon the detachable fixing of the first and second components to form a glued-in ball connection; and
subsequently welding the first and second components together without affecting the glued-in ball connection.

2. The method according to claim 1 , wherein the first and second components are vehicle components.

3. The method according to claim 1 , wherein the glue is hardened by supplying heat.

4. The method according to claim 1 , wherein the first positive-fit element is connected to the first component during production of the first component.

5. The method according to claim 1 , wherein the first component is a sheet metal component.

6. The method according to claim 5 , wherein the first positive-fit element comprises metal.

7. The method according to claim 1 , wherein the through-hole is configured in the form of an oblong slot.

8. The method according to claim 2 , wherein at least one of the two components is a fiber-reinforced plastic component.

9. The method according to claim 2 , wherein at least one of the first and the second vehicle components is a vehicle body component.
