BODY

BODY

-: Body is the main part of a vehicle and it make design  depend on the chassis frame and manufacturer

ADVANTEG OF BODY-:

1-: STRENGTH --- 

                              The is must be strong enough to with stand all type  of force to which the car is subjected , which include  the weight of the car passenger  and the luggage , inertia braking and side forces. It should also be able to cope with impact  load of reasonable magnitude.

2-: AIR DRAG --- 

                              The resistance of the air  during running depends  upon the body shape  and increases  directly as  the square of the vehicle speed . the shape of the body  should be such that the air dage ig minimum.

3-:WEATHER PROTECTION --- 

                               The design of the body  must be such that the occupants  and the luggage  are protected  form bad  weather .

4-LIGHTNESS----- 

                               The body should be as light as possible  in relation  to the amount  of pace  in side .

5-:PROTECTION OF ACCIDENT ---- 

                                This is very impotent consideration in the car body design. The body must be such that  the driver is at maximum ease so that there are  last chances of the accident  taking place  due to fatigue . how ever in case  thr accident take place  the body must protect  the occupants .

CHASSIS

  CHASSIS-:-

Chassis is the main base  of a vehicle . who carrying all accessories of a vehicle all are fitted in chassis .

TYPE OF CHASSISE-: THERE ARE THREE TYPES OF CHASSIS FRSME

1-    CONVENTIONAL FRAME

2-    INTEGRAL FRAME

3-     SEMI  INTEGRAL FRAME

****CONVENTIONAL FRAMW******

-: It has two long side members and no of cross member ( depend on manufacture)  joined  together with the help of bolts and rivets. That types of frame used generally heavy vehicle.

*******INTEGRAL FRAME****

-:This frame is used now a days in most of the cars. There is no frame and all the assembly units are attached  to the body . all the function of the frame  carried out bye the body  it self.  Due to elimination of long frame  it is cheaper  and due to less weight . most economically also .  ( only dis advantage is repairing difficult.

******** SEMI INTREGRAL FRAMW*******

-In some vehicle half frame in fixed  in the front end on which  engine gearbox  and front suspension is mounted  . it has the advantage  when the vehicle is meat an accident the front frame can be taken easily to replace  the damage chassis frame. This type of frames is used in some of the European  and American car 

BASIC INTRODUSE OF VEHILE

BASIC INTRODUSE OF VEHILE-:

     1-    Chassis.
2-    Bodycab.
3-    Driveline.
4-    Controlling.
5-    Electrical .

What is Automobile?

What is Automobile?

Automobile – 

                       There are Auto mince that generate power automatically by some technical process, And Mobile mince that moved one place to another place, depend by auto generate power. The above  presses together called Automobile.     

Definition- 

                   A self propelled passenger or goads vehicles that usually four or  many wheels  an  and internal combustion  engine  used for land transport  also called vehicle.  .

Automobile are use in many purpose , like as vehicle , marine , industry E T C.

NOTE-:  WE  ARE DISCUS BASICALLY A PART OF AUTOMOBILE VEHICLE.

TYPE OF VEHICLE -:  We divide   two types of vehicle

                                 -: passenger vehicle

                                -: goads vehicle

                                

-: passenger vehicle 1- bike,  auto, four Wheeler, bus E T C.

-: goads vehicle 1- TRUCK,  TIPPER,  PULLER,  LIGHT COMMERCIAL VEHICLE, E T C.

                               

                                  

History of automobile

History of automobile

The early history of the automobile can be divided into a number of eras. Based on the prevalent menace of population. Later periods were defined by trends in exterior styling size and utility preference.

In 1808 Friancois Isaac De Rivaz designed the first car powered by an internal combustion engine fueled by hydrogen.

In 1870 Siegfried Marcus built the first gasoline powered combustion engine and 1880 introduce a four cycle gasoline powered engine, and ingenious carburetor design and magneto ignition.

The similar four stroke diesel engine was invented by Rudolf Diesel, and used hydrogen fuel cell in the place of gasoline.
