Figure 23: Composite Construction (conventional separate chassis)
Integral (mono or unity) Construction
Integral body construction employs the same principles of design
that have been used for years in the aircraft industry. The main aim
is to strengthen without unnecessary weight and the construction
does not employ a conventional separate chassis frame for
attachment of suspension, engine and other chassis and
transmission components. The major difference between composite
and integral construction is hence design and construction of the
floor. In integral bodies the floor pan area is generally called the
underbody. The underbody is mad up of formed rails and
numerous reinforcements. In most integral under-bodies a
suspension member is incorporated in both the front and rear of
the body.
