Portal frame
Two portal frame constructions are used on the particularly stressed body areas in the Centurion. In the rear, one frame encloses the large opening of the car garage door and thus supports the torsional rigidity of the cabin. The second is used three-dimensionally in the living area and encloses the huge slideout. It not only stiffens the body, but also counteracts the compressive forces of the slideout air chamber seal with its strong frame.
Space-Frame
An aluminium space frame in the raised floor of the Centurion provides an extremely stable "basement construction" by connecting the subframe to the living space floor, creating a solid box. This intelligent construction keeps the furniture and wall structure permanently and firmly connected.
Engine sound insulation
The newly developed measures for engine sound insulation consist of several components for engine encapsulation. Silent blocks decouple the platform from the chassis. The engine receives an insulation package to the living area floor and to the side walls, as well as the original Actros noise encapsulation package. Due to a new frame design, particular emphasis was placed on the airborne sound insulation of the engine compartment lid.
