3. Drive Train
This mechanism consists of:
Clutch (clutch)
Transmission
Propeller shaft
Differential
Axle & Drive shaft
Mechanism changes energy generated by a machine called the "Power Train"

4. Clutch
Terms:
Can connected from engine to the transmission with smooth
Can move the engine to power transmission without slip
Can terminate the relationship with the quick and perfect
Position: Between the engine and transmission Function: To connect and disconnect cycles engine to the transmission

5. Cluct systems are used to disengage the engine from road
When the clucth pedal is depressed, the clucth is disengaged from the engine
When the clutch is engaged the engine, the engine power will transfer through the clucth to the road

6. SYSTEM COMPONENTS Flywheel: Transfer engine power the clucth
Input shaft: transfers power from clucth to the tranmission
Clucth Disc : spilne to input sahft, transfer power from engine the input shaft
Pressure plat assembly : Spring pressure tighttly holds the clucth to the flywheel

7. Release Bearing : Connected through linkage to the clucth pedal
Release Bearing : Connected through linkage to the clucth pedal. Provides a way for the pressure plate to release pressure on the clucth
Clucth Fork : Slide the release bearing into and away from the pressure plat assembly
Clucth Lingkage. Allows the driver to operate the clucth fork
Clucth Housing : Encloses the clucth assembly

8. Clutches operation Pilot bushing or bearing in center
of flywheel or crankshaft, supports
the end of input shaft
(friction disk) splined to transmission
Input shaft
(throw-out bearing
T/O bearing) allows
to push on rotating
clutch fingers
Bolted to Crank
Bolted to flywheel - Applies
the spring force to clamp the
friction disk to the flywheel
(clutch fork) pushes T/O bearing to release rotating clutch

9. With you foot off of the pedal, the pressute plat hold the clucth against the flywheel, alloing power to travel through the clucth to the input shaft of the transmission

10. With the clucth disesaged, the pressure releases it’s clamp on the clucth disc, which interrupts the power flow from engine

11. Clutches
Flywheel, Pressure plate, spring, end clucth cover are revolving. Clucth disc and clucth shaft are stopped to pressure plat Disengage
Pressure plate engage- seizes clucth disc and entire unit revolves

12. Fly Wheels Mounted on the rear of crankshaft
Control speed fluctuations of the crankshaft
Allows a method of starting the engine
Friction surface for the clucth
Cast iron or cold rolled steel

13. Transmission input shaft
Extends from the rear of engine crankshaft to the insade of the transmission case
Splined area where the clucth hub rides
Pilot area support front of input shaft in end of crankshaft
Transmission front bearing supports the end of the input shaft
Also called the clucth shaft

15. Clucth Disc Also called the friction disc
Located between the flywheel and pressure plat
Transmits power from engine to the input shaft
Made up of an outer disc assembly and central hub
Contains many grooves cut across surface for heart dissipation, removal of dust and dirt, and to break and vacum

16. Construction of the Clutch
Splines to input shaft
Of transmission
Clutch Disk or
Friction Disk

17. Outer disc assembly
Thin steel sandwiched between friction material or friction facing
Friction material is bonded or riveted
Friction material is devaiced into segments for even distribution
Spring steel between the facings help absorp the shock of engagement

18. Clucth Disc Facings Clucth Disc Facings
Like brake lining, asbeston was trasitionally used because of excellent coefficient of friction, heat dissipation. And low cost
Fedeal low as banned the manufacture of asbeston containing clucth facings after Agustus of 1992
Asbeston is replaced with fiberglass and aramid nonmetallic compounds of metallic friction facings, using various mixtures of powdered iron copper, graphite, and ceramic

19. 0,015 or less above rivets is considered worn out
When sectional lines come close to disappering is worn

20. Friction disks Often made of asbestos Must be put in only one way
Usually marked
Clutch won’t release if wrong
12/2001

21. Friction disks Cushion springs Waved metal between clutch half's
Dampen clutch engagement

22. Friction disks Torsional springs Can be spring or rubber
Dampen power impulses from crankshaft
12/2001

23. Torsional Springs Has pins to limit amount of twist.
Springs try to keep it centered between pins.
Springs sometimes get weak and start rattling or fall out

24. Disc clutch
Function:
Friction facing the field to play power forward from the engine to the transmission
Cushion plate to soften when the clutch related
Torsion damper for muted surprise when clutch related

25. Friction disks Torsional springs Can be spring or rubber
Dampen power impulses from crankshaft
12/2001

26. Hub flange
Splined hub engage the splines on the transmission input shaft
Made from cast iron
Hub flange and outer disc are riveted together with”stop pins”

27. Types of Clutches (pressure plates)
Coil spring
9 spring
12 spring
3 fingers for T/O bearing to push on

28. Clutch cover tipe coil spring
Clutch cover type coil spring Advantages:
   The emphasis on strong plate clutch Disadvantages:
   Energy to pressure plate clutch weight
   Construction complicated, so expensive price

29. Clutch cover type diagpragm
Diaphragm clutch cover model Advantages:
   Light energy emphasis
   Emphasis clutch plate more evenly
   Pedal power is not reduced by the style centrifugal
Disadvantages
The emphasis of the plate clutch smaller

30. Mechanism of mechanical clutch
Freeplay is the distance between the pedal and diaprahgma cushion liberator
Free play

31. Mechanism of hydraulic clutch
This type of movement on the clutch pedal to be changed by pressure hydraulic master cylinder which is then forwarded to the release fork through the release cylinder

32. Master Cylinder
Function: To generate pressure hydrolic

33. SOME ONE READ

34. Clutch Release Cylinder
Function: To forward the power of the master cylinder push release fork

35. Some are adjustable
for free-play and
some not

36. Automatic clutch (torque converter)
Note: Only used on vehicles equipped with automatic transmission
