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
  
   Types:

   Clutches are classified as

1.Friction clutch

  a. Single plate clutch

        2.Centrifugal clutch

3. Semi centrifugal clutch

        4. Diaphragm clutch (Crown spring type)

5. Vacuum clutch

6. Hydraulic clutch

7. Electro magnetic clutch

        8. Dog and spline clutch

        9. Overrunning clutch

Introduction to Automobile transmission system

                                  

                                   Introduction to  Automobile transmission system

 

    What is Automobile transmission system?

        A system is necessary to transmit the power developed by the engine to the wheels. This system is called as Automobile transmission system.

 

     PURPOSE OF AUTOMOBILE TRANSMISSION SYSTEM:

        To transmit the power from the engine to wheels.

      ARRANGEMENT OF TRANSMISSION SYSTEM:

 

      

        VARIOUS COMPONENTS:

      

•Clutch

•Gear box

•Propeller shaft

•Universal joints

•Differential

•Rear axle & wheels

 CLUTCH:

 

  To engage and disengage the transmission of power from engine to gear box.

  GEAR BOX:

 

 To provide

 •Various torque  / speed ratios

 •A neutral position

 •for reversing the direction

      UNIVERSAL JOINT

       To transmit torque at an angle

     PROPELLER SHAFT:




       A driving shaft that connects gear box to the differential.


     DIFFERENTIAL:
 

  To provide a relative movement to the two rear wheels while taking turn.


REAR AXLE:

 

To transmit power from differential to the driving wheel           

  

WHEELS

     •To move the vehicle

•To support the weight of the vehicle
