Introduction to clutch

                            Introduction to clutch

  Clutch is required to

• Keep engine alone  running

•Transmit power gradually

•Disengaged engine & gearbox ,when changing gears

 Location

  Clutch lies between the engine and the gear box

  Function       

  •To transmit power from   

   engine to the gearbox at the 

   will of the driver, by

   operating foot pedal/ lever

 Principle of  Operation

 

 

•Works on principle of friction

•The friction between two surfaces depends upon

•    Area of contact surfaces 

        •    Coefficient of friction 

        •    Pressure applied 

 Requirements

 

• To transmit the engine torque

• Engage gradually

• Ensure proper ventilation

• Dynamically balanced

• Damping of vibration 

•Clutch free pedal play

•   Smallest possible size

•   Pick up load smoothly

•   Easy to repair

•   Easy to operate
