Clutches

Hi friends,
Let us now discuss something about clutches.

Construction of clutches:
A typical clutch consists of three basic parts.They are:
1.Fly wheel
2.Friction disc
3.Pressure plate
Fly wheel drives the pressure plate.They attach to and rotate with engine crank shaft.The friction disc diameter is about 30cm or less and splined to the clutch shaft or transmission input shaft.Both must turn together but the friction disc must slide back and forth on shaft's splines.
The pressure plate with one or more springs attaches to the clutch cover.The fly wheel is bolted with pressure plate and rotate together.
When the clutch is engaged ,Spring holds the friction disc against the fly wheel.The engine crank shaft and transmission input shaft has the same centrelline.The small end of input shaft rides in a pilot bearing or bushing in the end of crankshaft.The transmission input shaft bearing supports the other end of input shaft.

Uses and functions of clutch
1.Clutch can disengage the gear and engine.Thus engine can run idle without power being transmitted to gear.(However it wastes fuel,that is why we are advised to use minimum clutch and drive with a constant speed)
2.Allows the driver shaft to transfer into proper gear when clutch is disengaged.
3.While engaging,the clutch slips momentarily.This provides smooth smooth engagement of various gears and gear trains.
4.It transmits power from Engine to gear when engaged.

So what say everyone?😁
