Fastening the module crossmember
To achieve the highest precision, our tolerance compensation systems are used for fastening the module crossmember, because the considerable size of the support structure sometimes results in large tolerances at the screw points. In addition, a joint gap between the module crossmember and the A-pillars is planned for assembly to prevent jamming during positioning. In order to be optimally connected to the body, the already assembled component must then be positioned with millimeter precision at the bolting points during assembly. The WITOLs ensure that the joint gap and the component tolerances are automatically compensated for during bolting. In addition, the WITOLs can be supplemented with sound insulation or vibration dampers for the instrument panel to eliminate the transmission of engine noise to the interior.
Reliable and precise tolerance compensation even with blind assembly
The bolting of the module crossmembers to the body poses a particular challenge – especially in the area of the frequency struts with the support towards the bulkhead, because assembly here is carried out from the engine compartment. In general, the screw points for fastening the module crossmembers are not fully visible, so there is no view whatsoever of the component. The two components have to be connected here by the so-called blind assembly.
The use of WITOL tolerance compensation elements enables a smooth blind compensation, ensures a precise and process-safe assembly and reliably compensates deviations at the screw points with tolerances. This optimizes the entire manufacturing process.
