INTRODUCTIONThe concept in the report is strictly based on HONDAmanual cars. The report describes about components andfeatures of parts of cars or vehicle . It covers the light four-wheelervehicle. The description is about as follow:- Tools and equipment used in workshop. Suspension system of cars. Steering system of cars. Battery and battery recharge. Brakes . Some other components. 5.

Shock observe andthe linkage that connects a vehicle to its wheel. Suspensionsystem serve a dual purpose-contribution to the cars roadhandling /holding and braking for good active safety anddriving , pleasure , and keeping vehicle occupantscomfortable and reasonably well isolated from road noise ,bumps and vibrations etc. these goals are generally at odds ,so the tuning of suspension involves finding the rightcompromise. It is important for the suspension to keep theroad wheel in contact with the road surface as much aspossible, because all the forces acting on the vehicle do sothrough the contact patches of the tyre. The suspension alsoprotects the vehicle itself and any cargo or luggage fromdamage and wear. The design of front and rear suspensionof a car may be different. 8. STREEING SYSTEM Basically steering system is of three types. These are as follow:- Mechanical Steering system. Hydraulic Steering system. Electrical Steering system. In average conditions hydraulic steering is used. When driver rotates thesteering wheel it applies forces on drive shaft. Drive shaft consists of steeringboots and end. Steering boot is made up of rubber, this rubber by contractionmakes drive shaft to take turn even when vehicle is moving in speed. The combination of steering system and transmission system are so connectedto the tyres that steering system even works when vehicle is at high speedwithout effecting its speed. The soul job of steering system is to take turn onroad. 9. STREEING SYSTEM FRONT VIEWSTREEING SYSTEM ASSEMBLY TRANSMISSION SYSTEM 10. TRANSMISSION SYSTEM Transmission system acts like arteries and veins of a vehicle or it is spine of thevehicle. Transmission system transmits engine power to tyres. The main components of transmission system are given as follow. Thecomponent of transmission system are given as follow . The components are soarranged and assembled in a system that they make the equivalent effect as perwish of the driver. Clutch Gears Differential Sun and Star pinion Tyres 11. CLUTCH It disconnects and connects the engine power todifferential or gear box in manual cars. Where clutch isin use or is pressed by drivers feet the it tends torestrict the engine power to reach gear box. Now inadvanced or high performance cars torque converter isused instead of clutch because it is more accurate, safeand efficient then clutch. Clutch plates and pressureplate are connected to each other with direct contact. 12. GEAR Gear box is assembly of circular types of concentric platesthat has teeth on there curved surface. The main task ofgear is to change the torque and R.P.M (Revolutions Perminute) of tyre. Whenever gear of vehicle is changed, thespeed and torque of car is also changed. Smaller thedesignated number of gear more will be torque and lesserwill be the R.P.M or vice versa. Commonly vehicles have 4 to 5 gears. Whenever gear isadjusted to neutral then power coming from the engine isnot transmitted to tyres, hence at that time, gear produceszero power and zero R.P.M. 13. DIFFERENTIAL A large circular gear that is used to transmit final power coming from engine tyres. Differential is used to transmit equal amount of torque toboth tyres at 90 degree Whenever vehicle takes a turn, the inner wheel areprovided less moment and outer tyre are provided moremoment for easy turn. 14. BATTERY AND BATTERYRECHARGING Battery is device that supplies current to vehicle componentswhich are used in many ways. Battery is used to run wipers,headlights starter and many other components. Battery afterbeing used for a long time loos the concentration of charge,hence it produce less current then its claimed current value. Soin order to recharge battery the following 2 systems areintroduced in vehicles. DYNAMO:- Dynamo is device that produce A.C current. Itconverts mechanical energy into electrical energy of A.C type.When flux changes in the dynamo, it produces current. Dynamowas used to recharge the battery of vehicle. Battery in all vehicleshave same voltage but they come in different ampere value. Butdynamo because of having some limitation is not now used innew advanced vehicle with compatible assemblies. So toovercome this ALTERNATOR is designed. 15. LEAD ACID BATTERY FOR CARSDYANMO 16. BRAKING SYSTEM BRAKES:- Brakes are devices that are directly introduced to vehicles tyre. Thebrakes are used to lower down the acceleration of vehicle or to stop the vehicle. Most commonly brakes are divided into 2 types:- Disc brakes or quick brakes. Drum brakes. Disc brakes or quick brakes:- In disc brake a circular disc connected to tyrerotates in between 2 lather. Disc brake works on hydraulic principle. There arepistons introduced to lather of disc brakes whenever the driver presses thebrake by feet the piston expand and hold the disc tightly. As this disc is verytightly connected to tyre so when this disc stops to rotate, it stops the tyre too.Disc brake is also called quick brake because it stops vehicle very quickly.Basically disc brake is used in light vehicle because light vehicle produce lessmomentum and are safe to stop quickly. 17. FRONT AND REAR BRAKE SYSTEMFRONT DISC AND REAR DRUM BRAKES 18. CRANK SHAFT AND ITSCOMPONENT MAJOR PARTS:- Fly wheel side. Timing side. General (commonly there are five general). Weights. CONCEPT OF CRANK SHAFT:- When the key of vehicle is on then it starts the vehicle. Starter rotates the flywheel and hence starts the engine. Piston in engine rotates the crank shaft.When piston takes the power stroke then crank shaft gets power to rotate butrotation to crank shaft is provided by fly wheel by other three strokes i.e.suction compression and exhaust. Hence the main stroke is power stroke. 19.
