> Body Construction Vehicles

By :Taufiqullah Neutron (Masteropik)

Car parts are divided into 2 major groups, namely the body and
chassis. Part of the vehicle body is formed in such a
way, (in general) made of metal plate (steel plate) which
thickness between 0.6 mm - 0.9 mm as a passenger or goods.

Chassis is part of the vehicle that serves as
sustaining the body and consists of the frame (frame), engine (engine), power train
(Energy transfer), wheels (the wheels), steering system (steering system),
suspension system (suspension system), brake system (brake system) and
Other completeness.

Based on the attachment of the body on frame construction, the
there are 2 types of vehicle body construction, ie composite construction
(Alone) and construction monocoq (attached).

Framework is attached to his place all the components
vehicle including the body. Framework must be strong, lightweight, sturdy and resistant
to vibration, or shock received from the condition of the road. Facebook
strong then there is a box truss construction, the shape of U or pipe, which
generally consists of two rods that elongate and connected
with a transverse section. In the early development of body technology
and the vehicle frame, body and frame are made separately
(Composite body) but lately the body and frame are made together
(Monocoque body, also called the integral body), especially in
sedan vehicle.

Separate Construction (Composite)
It is a type vehicle body construction where the body and chassis
separately. Linkage / connection between body and frame using
bolts and nuts. To improve comfort during use, then
between body and frame mounted rubber as a means of dampening vibration.

Construction framework of a separate body and this makes it easy
in replacement of vehicle body parts were damaged,
body especially the lower-or-break order. This construction
usually used on the old type of sedan vehicles, vehicle
passenger and freight cars. (Eg trucks, buses, pick-ups and
etc.).


Converge construction (monocoque)
It is a type vehicle body construction where the body and frame
composed into a single unit. This construction uses the principle of skin
eggs, which is a unified whole so that all load
divided evenly on all parts of the skin. Linkage between body and
order to use the weld.

Because the body and frame together, then the shape can become more
low compared with the composite type so that the point of gravity weight
lower will cause the vehicle more stable. This construction
used on the sedan, even a few vehicles MPV (Multi Purpose
Vehicle) began implementing monocoq body construction.


Frame Types
Based on the shape, order vehicles can be divided into several
types, namely: (a) order form H, (b) frame the perimeter, (c) frame
form X, (d) framework forms the backbone (backbone), and skeletal
form the floor (platform frame).

Order form H.
Its construction is very simple, easy to make, widely used for
vehicle bus, truck.


Perimeter Frame.
Framework of the perimeter is a revised form of H, the body attached
on the edge of the frame so that the position of the floor can be lowered. Reduction
floor of the vehicle will lower the center of the vehicle weight and height
reduced vehicle so that steering a steady, passenger space
become more freely, widely used for the sedan.


Order form X.
Beam frame construction consists of two rod-shaped main frame
longitudinal beams together in the middle. Place of engagement with
body and the doors can be made low enough for easy in and out
vehicles, robust against rotation, used to the old type sedan.


Order forms Spine (Back Bone).
Construction framework of a single model framework, the middle
bear the burden (back) and arms that stand out as the holder
body. This kind of frame construction also allows the center weight
vehicle is made lower. Construction framework of this model often
used for passenger cars and trucks.


Floor Model Frame (Frame Platform).
Body and frame welded into one, so it is a form
integrated, allowing the interior space is made large. Another advantage
the use of frame construction this model is resilient
good enough against bending and torsion.
