Abstract
The board frame is a fully supporting board concept for commercial vehicles. The essential amount of structural strength is being provided by a surrounding main member. This surrounding member has the outside dimensions of the vehicle. Its height ranges from lower edge of the rim up to upper edge of the tire. The smooth surface and external finish of this member lead to an acoustic capsulation of rolling noise, lessen any spray problems and provide a gliding surface to reduce the degree of collision impact. An application out of extruded aluminium profiles will clearly reduce the dead weight in spite of optimized passive safety. (A)
