Clutch
Types of Clutch Linings:
1. Solid Woven Lining types
2. Moulded Lining types
Solid Woven lining type In this type, Clothes are stitched with the suitable thickness.
Moulded lining types It is formed with the help of asbestos, fibre, glass particles, cloth, metal powder and sticking component with particular pressure.
Clutch
Clutch Lining The two ends of the clutch lining and clutch plate are attached with the help of rivets or some special glue.
The clutch lining is made up of following materials.
1. Asbestos
2. Reybestos
3. Fibre
4. Leather
5. Cork
Clutch
The clutch plate is made of steel with a centrally located hub containing splines. It has moving capacity and is attached to a disk surrounded by cushion springs. Friction lining is secured with rivets or glue. A helical spring in the center absorbs torque, known as the torsional or damper spring.
Clutch
Components of Clutch :
1. Clutch Plate
2. Clutch Lining
3. Pressure Plate
4. Coil Spring
5. Release bearing
6. Clutch linkage
Clutch
Qualities of Good Clutch :
1. Should have high torque transmission.
2. Should join in step-by-step.
3. Should be a good transfer of heat.
4. Operating balance is required.
5. Should be able to bear the shocks.
6. Should have free pedal play.
7. Should be easy to operate.

10. Should have high co-efficient of friction
Introduction to Automobile
Electrical system supplies electrical energy which is used to produce the spark for igniting the air fuel mixture in petrol engines, to provide light for the vehicle during night ride, to operate the wiper motor, to light inside the vehicle, to play music and for dashboard lights.
Introduction to Automobile
Wheels and Tyres: The wheels help to carry the vehicle’s entire weight and to drive the vehicle. The wheels are connected to the front and rear axles of a vehicle. They absorb the vibrations produced from the road and help to keep the tyres soft and smooth
Introduction to Automobile
Brakes are installed on the four wheels of the vehicle and work through mechanical connections, hydraulic and air. The very important part of an automobile is the braking system that helps to drive and control the speed of the vehicle within safe speed.
Introduction to Automobile
The steering system operates on a very simple mechanism that directly transforms steering wheel rotation into straight line movement and helps in turn the vehicle as per the road.
Introduction to Automobile
Suspension System is the Spring Shock absorber has been connected to the front and back axles and helps to drive the vehicle smooth and slower from the vibrations in the road.
Introduction to Automobile
The rear axle connects the rear wheels, aiding in turning on curved roads. The differential gear in the center adjusts speed via the propeller shaft, transferring power at a 90-degree angle to the wheels.
Introduction to Automobile
The front axle connects the front wheels, supporting the vehicle’s front weight while enabling steering and absorbing road shocks.
Introduction to Automobile
The propeller shaft is a long hollow shaft that transmits power from the gearbox to the differential. Positioned between these components, it ensures efficient power transfer.
