ABSTRACT:
A carriage body frame with a passenger compartment having longitudinal load-bearing sections of aluminum and light-weight composite panels between the load-bearing sections is such that the composite panels feature a plastic core with aluminum outer sheets adhesively bonded to both sides. The outer sheets extend partially over an aluminum connecting section which is integral to the composite panel; and fit to this by virtue of shape. The connecting section exhibits connecting strips which rest on correspondingly arranged connecting strips on the load-bearing section. The connecting section is joined to the load-bearing section by of laser welding. The outer sheets are joined at a free edge, likewise by laser welding, to the connecting section and, in the region of at least one connecting strip, the connecting section exhibits a U-shaped longitudinal channel which acts as a trap for adhesive and over which an outer sheet passes.
