3. DEFINATION
CLUTCH
Engages and Disengages the Power
Transmission
 Connect and Disconnect
Two Rotating Shafts
 Driving Part(Power unit)
attached Driven Part

4. PURPOSE
Clutch is Designed with
Following Requirements
Allow the vehicle to come to a
stop while the transmission
remains in gear
Allow the driver to smoothly take
off from a dead stop
Allow the driver to smoothly
change gears
Must not slip under heavy loads
and full engine power

5. PRINCIPLE OF OPERATION
 Works on principle of friction
 When two friction surfaces are
brought in contact & pressed, they
are united due to friction
 Friction between three surfaces
depends upon
a) Area of surfaces
b) Applied pressure
c) Coefficient of Friction

6.  Torque Transmission
Gradual Engagement
Heat Dissipation
Dynamic Balancing
Vibration Damping
Size
Free Pedal Play
Easy in Operation
Lightness

9. Hydraulic Clutch
• Operated by Oil
Pressure
• Working Principle
by Pump and
Accumulator
Centrifugal Clutch
• Uses Centrifugal
Force
• No Need of
Clutch Pedal for
operation
• Ted in any Gear
by pressing
Acceleration
pedal
Electromagnetic
Clutch
• Flywheel Winding
• Current Supplied
by battery
• Electromagnetic
Field Generation
for Pressure Plate
Attraction
Vacuum Clutch
• Consists of
Vacuum Cylinder,
Solenoid
Operating valve,
Reservoir
• Movement of
Piston by Clutch
• Spring Force

10. Cone Clutch
• Friction Surface in
the form of Cone
• Spring Force
• Engagement of
the Clutch
Single Plate Clutch
• Mounted on
Spline of Clutch
Shaft
• Arrangements &
Connections
• Engagement &
Disengagement
Multiplate Clutch
• No. of Clutch
increase in
Friction Surface
So, More Torque
Transmit
• Working Principle
by Clutch Plate &
Flywheel
