Introduction & Definition of Automobile
In the 'Introduction to Automobile', we learn the types of automobiles their
mechanism of transmission (final drive) systems & its applications,
automobile industry & its history, major automobile components like
chassis, frame, body, power drive etc., and advanced automobile
safety system, electric systems & devices.
'Automobile' is a wheeled motor vehicle (land
vehicle), which powered or propelled by an IC engine, and it is used for
transportation of passengers & goods on the ground. A motor vehicle which
can move by itself. And say, it is self-propelled vehicle. Most
definitions of automobile say, a motor vehicle have run
primarily on roads, seat one to eight people, have four tires, and mainly
transport people rather than goods. Examples are Car, jeep, bus, truck,
scooter or motor cycle etc.
Automobile
engineering deals with everything about automobiles and different practices to
propel the automobile.
The
different types of automobile vehicles are used for transportation of passengers
& goods. It may be as per uses, application and or type work. The various
choices are available in today’s market.
Basically
all the types of vehicles works on the principle of internal combustion
processes or sometimes the engines are called as internal combustion
engines.
Different
types of fuels are burnt inside the cylinder at higher temperature &
pressure to get the transmission motion in the vehicles. Most of the
automobiles are propelled or powered by IC engines only.
But
current scenario different power plants (sources) are available for propelled
the automobile. The different power sources are like battery or electric power,
solar power, hydrogen water fuels, and much more renewable resources. But those
also have some limitations to application on automobile.
Therefore,
every mechanical and automobile engineer should have the knowledge of
automobile engineering its mechanism and its various applications.
Automobile is a combination of large number of parts. Automobile can be divided into two major constituents the body and the chassis.
The body is that part where passengers have occupies their seats or the luggage and other placed cargo to be carried.
The chassis is the principle of any automobiles skeleton portion in which have constituents like frame, engine, transmission, axles, steering system, controls, wheels & tyres etc. that are all build together to make an automaton.

| Automobile Chassis Layout |
Automobile is made up of the following major components:
(A) Frame
work / Basic structure,
(B)
Engine,
(C)
Trans-mission system,
(D)
Controls,
(E)
Auxiliaries,
(F)
Superstructure,
(G) Body
/ Coachwork.
(A to
E, becomes chassis component).
The basic structure: It consists of the
frame, the suspension system, axles, wheels and tyres.
The engine: it is the primary need or power
source of any automobile. It provides the motive power for motion of the
vehicle. Once engine is functions well then all the various systems performing
properly. The automobile engines are mostly an internal combustion types.
The
transmission system: It consists of a
clutch, a gear box and a propeller shaft to transmit the torque
output from the gear box to the rear axle and a
differential gear to distribute the final torque equally between
the driving wheels. This is all about the short description of final
drive.
The
controls: They consist of steering system and
the brakes.
The
auxiliaries: The principle one out
of these is the electrical system.
The
superstructure: In those cases
where frameless construction is not adopted there must be a superstructure.
A superstructure is an upward extension of an existing basic structure above a
baseline. It may be say the degree of freedom is zero for that construction.
The superstructure might be separated from its foundation (framework) by engine
and other moving parts vibration. All together, these implement the system of
damage protection called base isolation.
The
body: body is nothing but the face of
automobile. Body is provide ergonomics feature in any automobile. It
consist of doors, windows, side panels, fenders, front & rear bumpers,
grille, pillar etc. Automobile body have provide safe, comfort, protected
& pleasant environment for all the passengers.
