2. What is clutch?
• A Clutch is a machine member used
to connect the driving shaft to a
driven shaft, so that the driven
shaft may be started or stopped at
will, without stopping the driving
shaft.

3. Function Of Clutch
 Clutch is used to transmit power from driven shaft to
driving shaft.
 In automobiles, where vehicle can be stopped for a
while or to change the gear, the requirement is
that the driven shaft should stop but the
engine should run naturally under the no
load condition.
 This is achieved by using clutch mounted
between engine shaft and gearbox shaft and
which is operated by a lever.

4. Multiplate Clutch
• Multiplate clutch is used when large
torque is to be transmitted e.g. motor
cars and machine tools
• Multiplate clutch is used when compact
construction is required e.g. scooters
and motor cycles.

8. • To overcome this problem the plates are fitted with small
springs to push the plates apart.
• Generally wet type clutch is used in automatic gearboxes,
and is operated by a piston governed by hydraulic
pressure.
• Wet type clutches are usually used in lates motorcycles.
•For the clutch disengagement, the
end plate is withdrawn to compress
the springs and release the other
plates.
•In this arrangement it is difficult to
ensure the disengagement of all
plates.

9. • The several advantages of the single-plate
clutch, specifically its ability to completely
disengage the drive.
• However, a multi-plate type of clutch finds a
use in automatic gearboxes.

10. Multiplate Clutch
Notes:
• In case of new clutch ,the intensity of
pressure is uniform along the surface of
clutch. [ Uniform Pressure theory is
used ]
• But in case of old clutch - Uniform
wear theory is more correct.
• In actual practice, usually the theory of
uniform wear is used in analysis of
clutch.
