1. Automobile Chassis :
chassis layouts : Concept of Chassis, Types of chassis layouts to be covered with arrangement
of different components on it .
• Chassis is a basic structure of vehicle. Chassis carry all parts of vehicles.
Automotive chassis is a skeletal frame on which various mechanical parts like
engine, tires, axle assemblies, brakes, steering etc. are bolted

, • Automobile chassis is usually made of light sheet metal. It provides strength needed
for supporting vehicular components and payload placed upon it.
• Automobile chassis helps keep an automobile rigid, stiff and unbending. Auto chassis
ensures low levels of noise, vibrations and harshness throughout the automobile.
• The frame is made of Box, Tubular channel or U-shaped sections ; which are welded or
riveted together.
Types of Chassis ( According to control )
• Backward control ( conventional chassis )
• Forward control
• Semi – forward control
Backward control ( conventional chassis)
• Here engine is usually mounted in front of driver’s seat. This offers advantage as safety
of driver in case of head collision.
• Driver’s front view is reduced as well as space utilization for pay load is also reduced.
Forward control chassis
• The engine is mounted completely inside driver’s cabin.
• Full utilization of space.
• Driver’s safety is reduced to large extent in case of head on collision with other vehicle.
Semi- forward control chassis
• Half engine fitted inside driver’s cabin.
• This chassis layout gives advantage good drivers safety and more space utilization.
Typical Layouts in Automobile :
1. Front Engine Rear Wheel Drive (FERWD)
2. Rear Engine Rear Wheel Drive ( RERWD)
3. Front Engine Front Wheel Drive (FEFWD)
4. All Wheel Drive ( AWD)
5. Articulated Vehicle Layout ( AVL)
