It’s the rigid base to which everything else is attached. A large seating cabin, or body, then sits on top of the horizontal frame. Most of the American-manufactured unibody automobiles used torque boxes in their vehicle design to reduce vibrations and chassis flex, with the exception of the Chevy II which had a bolt-on front apron (erroneously referred to as a subframe). The first true spaceframe chassis were produced in the 1930s by Buckminster Fuller and William Bushnell Stout (the Dymaxion and the Stout Scarab) who understood the theory of the true spaceframe from either architecture or aircraft design.[22]. Even stronger than SG112 with good formability. It is defined as:[5]. Originally, boxed frames were made by welding two matching C-rails together to form a rectangular tube. They employed the use of a strong structure below the doors to get more overall strength. The sheet metal used to assemble the components needs to be stamped with ridges and hollows to give it strength. It is now seen mainly on trucks. Monocoque being french for ‘single shell’ or a ‘single hull’. Opel was the second European and the first German car manufacturer to produce a car with unibody structure – production of the compact Olympia started in 1935.
