The Superstructure of Automobile:

In the case of integral or frameless constructions, the body is an integral part of the chassis. But, in the case of the traditional chassis, the body or superstructure is made after receiving the chassis from the manufacturer.

Body size

Body size depends on the end-use for which the vehicle is designed.Travel comfortably; cushioned seats are provided. To protect the passengers from dust & rain, the body has glass panes all over it. The bus is made of body metal, such asSteel section pillars with steel sheet paneling,Steel section poles with aluminum paneling andAll aluminum bodies, i.e., pillars, structures, and paneling made of aluminum squares and sheets.

This is because aluminum is much lighter in weight than steel.The driver’s compartment is covered in the body of a truck, and the rest is kept open. Such bodies are usually called load bodies.

In most cases, it is an open body, while for liquids such as water, milk, and fuel products, tanks are mounted on the chassis. The body is attached to the chassis with the help of I- or U-bolts with rubber packing between the chassis and body cross members.
