Definitions
- the invention relates to a method for connecting at least two components, in particular body components of motor vehicles, according to the in the preamble Art defined by claim 1.
- DE-OS 1 811 010 describes a mutual method Connecting two metal parts known at which the metal parts on their abutting surfaces with each other opposite, expanding inwards Recesses are provided. Form these recesses in the case of joined metal parts, a coherent Cavity. To connect the two parts heated metal is introduced into this cavity, the shrinks on cooling and thus contracts the metal parts.
- US Pat. No. 982,265 describes a method for binding a rod to a pipe, with metal in the pipe is poured and thus the rod with the tube is connected.
- the object of the present invention is a method to connect two components to create which a simple, safe one, particularly in body construction and represents a suitable connection for series production.
- this task is characterized by Features mentioned in claim 1 solved.
- the core which has recently solidified, runs through the connecting part in the area around the undercut of the first component when it solidifies, that there is a tension with very high Forces results when the connecting part is completely solidified to an extremely stable connection between the first component and the connecting part leads.
- connection part attaches to the connecting part, which ultimately the two components together in a simple manner get connected.
- connection part Depending on the selected form of the Connection part thus creates a connection of the second component to the first component in any Way.
- Figures 1 and 2 each show one as a longitudinal beam 1 formed first component in its entirety not shown vehicle body.
- Side member 1 runs in the longitudinal direction of the vehicle body, e.g. on a roof side, and points on one Side surface an undercut 2, which in in this case as a known dovetail guide is trained.
- undercut 2 can only be in a partial area the length of the longitudinal beam 1 may be provided, runs mostly for manufacturing reasons over its entire length.
- a not shown Cast mold in which then liquid metal is cast to form a connecting part 3.
- the mold can vary depending on the one used Casting process in a manner known per se as Sand, mold or die casting mold.
- the connecting part 3 and the undercut 2 are designed or coordinated so that in the case of solidification, a core area that solidifies last 4 of the connecting part 3 in the undercut 2 located part of the connecting part 3 contracts, so that by the result arising voltages the connecting part 3 with the Component 1 firmly connects.
- a second component 6 in this case a Cross member 6 of the vehicle body attached.
- This can be established using proven connection methods, e.g. Screwing or welding is done.
- welding of the cross member 6 to the connecting part 3 are far fewer and smaller weld seams required, than with a direct welding of the cross member 6 on the longitudinal beam 1, as is the case with the Technology is the case. This results in a lot less tension and a lot less Delay in both components 1 and 6.
- the component 6 abuts in the cases shown Component 1 T-shaped. It can through the connecting part 3 Depending on requirements also components with any other angles are connected to each other, whereby the connecting part 3 can also be bent.
- the second component 6 can be cylindrical, rectangular or of any other cross section. Of course then the area 5 of the connecting part 3 to the corresponding cross section of the second Component 6 adapted.
- negative undercut 2 is a according to FIG. 2 Side member 1 with a so-called positive undercut 2 shown.
- the connecting part 3 fits in both cases when casting to the corresponding one Undercut 2 and it results as already set out above by the last solidifying core area 4 a firm connection between component 1 and the connecting part 3.
- a casting mold with which it is also conceivable two or more connecting parts 3 with one single cast can be cast onto a side member 1 can.
- Several cross members 6 could then also be used in this way be attached to a side member 1.
- the method described is known for all Casting process and alloys or materials feasible.
- the type of attachment of the cross member 6 the connecting part 3 can vary depending on the material.
