Integral bodyshell structure for a motor vehicle and method for its production. Known vehicle bodyshell structures are composed of a multiplicity of individual sheet-metal stampings, and as a result complex joining processes for the sheet-metal shell construction arise. In the invention, first the inner side-wall part is joined on each side to the under-frame assembly and then the outer side-wall parts are added. This method has applications for the production of passenger cars.
A vehicle body includes an underbody having one or more underbody bolting flanges attached thereto, with each underbody bolting flange being adapted for bolted attachment to a mating bodyside bolting flange. Left and right bodyside subassemblies are joined to the underbody, with each bodyside including a supplemental bodyside support structure having attached thereto one or more bodyside bolting flanges, with each bodyside bolting flange being adapted for bolted attachment to one of the underbody bolting flanges after the bodyside subassemblies are otherwise joined to the underbody. The underbody bolting flanges are attached to supplemental crossmembers that are attached to and extend across the underbody.
A side panel for a motor vehicle includes a bottom sill member, a roof panel portion, and a plurality of pillars extending between the sill member and the roof panel portion. The sill member forms with the pillars and the roof panel portion a single-piece structure from a sheet metal blank made of high-strength steel and has at least one region which is partly hardened and subject to increased load in the event of a crash of the motor vehicle.
Disclosed is a front frame reinforcement structure of a vehicle including a front column including an inner panel and an outer panel coupled to each other to form a closed structure, a side frame welded at one end thereof to one end of the front column, a reinforcement panel welded at one end thereof to the one end of the front column, the reinforcement panel being welded at the other end thereof to the other end of the side frame so that it defines a closed structure enclosing the front column, together with the side frame, and a dash panel welded at one end thereof to the other end of the reinforcement panel. This front frame reinforcement structure provides an enhancement in the bending and torsion rigidity of a vehicle body, thereby being capable of suppressing an injure of occupants when impact is applied to the front part of the vehicle due to a collision accident.
An underbody assembly for a motor vehicle includes a floorpan extending longitudinally and transversely. The underbody assembly also includes a side sill operatively connected to the floorpan to provide more than one underbody load floor height of the floorpan relative to body side assemblies of the motor vehicle.
A motor vehicle roof with a roof module (10) for attachment to the roof frame area of a motor vehicle body, with support edges (15) for the roof module (10) which inwardly adjoin the side rails (14) of the vehicle body, the roof module (10) having an outside roof skin (11) which has side edges (16) which are bent downward toward the support edges (15). On the roof skin (11), in the area of its side edges (16), there are connecting strips (18) which have bottoms for attachment to the support edges (15) of the roof frame area and which are joined to the roof skin (11), preferably by being injection molded or foamed on to it.
