Two parts e.g. tunnel, assembling method for motor vehicle, involves positioning tunnel and sub tunnel crosshead in orifices by penetration of screw, and integrating crosshead with tunnel by setting tunnel and crosshead on screw

摘要

The method involves positioning a tunnel (2) and sub tunnel crosshead (4) of a motor vehicle in orifices (12) by penetration of a screw (10), where the tunnel and the crosshead are made of sheet. The crosshead is integrated with the tunnel by setting the tunnel and the crosshead on the screw, where the setting of the tunnel and the crosshead on the screw is performed simultaneously. The tunnel has thickness of about 0.95 millimeter, and a sub tunnel crosspiece has thickness of about 1.5 millimeter.
