Clutch function
Componets of Clutch:
Flywheel mounts to the engine crankshaft
Clutch Disk–the friction material assembly that provides easy engagement andfirm torque transference
Pressure Plate: – also known as “Clutch Cover” – this is the spring-loaded surfacethat locks the clutch
Throw out bearing:–also known as “Release Bearing”
Pilot bearing:-centersand supports the transmission input shaft (many cars do not havethis bearing)
Clutch cable:–mechanical release mechanism for some vehicles
Clutch Master Cyliner:–force-multiplying cylinder for vehicles with hydraulic releasemechanisms
Clutch slave cylinder:–used along with a Master Cylinder for hydraulic releasemechanisms
Misc.hoses, lines, brackets, linkages, etc– varies from vehicle to vehicle Function of the clutch:
In an automobile clutch, the flywheel is connectedto the engine, and the clutch plate is connectedto the transmission. When your foot is off the pedal, thesprings push the pressure plateagainst the clutch disc, which in turn presses against theflywheel. This locks the engine to the transmission input shaft,making them spin at the same speed. The amount of force the clutchcan hold depends on the friction between the clutch plate and theflywheel, and how much force the spring puts on the pressureplate.
When the clutch pedal is pressed, a cable or hydraulic pistonpushes on the release fork, which presses thethrow-out bearing against the middle of the diaphragmspring. As the middle of the diaphragm spring is pushedin, a series of pins near the outside of the spring cause thespring to pull the pressure plate away from the clutch disc. Thisreleases the clutch from the spinning engine.
Parts description:
The Engine:
The engine runs the car. Without it working well, car won’tfunction. The backbone of the engine is the crankshaft, and it isthe hardest working part of the engine. The crankshaft drives allbelt-driven accessories, such as the water pump, the alternator,the A/C and the fan. But, it’s primary function is to change thegive-and-return motion of the piston and rod into a circling motionthat is transferred to the transmission, and drive wheels. As thefuel/air mixture in the cylinder burns, it forces the pistons down.Each piston is connected to the crankshaft by a connecting rod. Asthe piston goes down, the connecting rod causes the crankshaft toturn.
The Flywheel:
The flywheel does a lot of things – it acts as a balancer for theengine, reduces vibrations caused by cylinders firing, and itprovides a smooth surface friction surface for the clutch. But theflywheel’s main function is to transfer engine torque (the turningeffort produced by the pressure from the crankshaft on the pistons)from the engine to the transmission. The flywheel connects theclutch and the driveline to the engine. One side is bolted directlyto the crankshaft, and one side is bolted to the clutchassembly.
The clutch disc:
Sandwiched between the flywheel and the pressure plate, the clutchdisc is covered with friction material on both sides. The center ofthe disc – called the “hub” – is splined to match the splines onthe input shaft of the transmission. Each clutch disc comes with aset of springs, located in the hub, called the torsion dampersystem. These springs are designed to cushion the engagement byabsorbing a portion of the impact when the disc is squeezed betweenthe flywheel and the pressure plate. In street applications, thecentral hub is a separate part connected to the clutch with marcelcushion springs. This absorbs any engagement impact.
The Pressure plate:
The Pressure Plate is, basically, a spring-loaded clamp that isbolted to the flywheel. The pressure plate presses the clutch discand allows for the transfer of power to thetransmission.
The Throw-out bearing:
When the clutch pedal is pressed down, this bearing – also calledthe Release Bearing – moves toward the flywheel. It pushes inagainst the pressure plate’s release fingers and moves them againstthe force of the plate’s springs. This action moves the pressureplate away from the clutch disc, interrupting the flow of power andreducing friction.
The clutch fork:
This piece provides a lever action to engage or disengage theclutch. It forces the throw-out bearing into the pressureplate.
The Trasmission:
The Transmission provides several selectable gear ratios, whichallows the driver to match the engine output to a variety ofdriving conditions. starting from a dead stop – as we accelerate,the engine needs to spin quickly to make the necessary power tomove the car. once we reached the speed limit, the car needs lesspower to maintain speed. So, the transmission uses a high gearratio (lots of power, but not much speed) during initialacceleration, when climbing hills. It uses a low ratio (lots ofspeed, but not much power) when we cruising.
