Clutch function  

Componets of Clutch:

Flywheel mounts to the engine crankshaft

Clutch Disk– the friction material assembly that provides easy engagement and firm torque transference

Pressure Plate: – also known as “Clutch Cover” – this is the spring-loaded surface that locks the clutch

Throw out bearing:– also known as “Release Bearing”

Pilot bearing:-centers and supports the transmission input shaft (many cars do not have this bearing)

Clutch cable:– mechanical release mechanism for some vehicles

Clutch Master Cyliner:– force-multiplying cylinder for vehicles with hydraulic release mechanisms

Clutch slave cylinder:– used along with a Master Cylinder for hydraulic release mechanisms

Misc.hoses, lines, brackets, linkages, etc – varies from vehicle to vehicle Function of the clutch:

In an automobile clutch, the flywheel is connected to the engine, and the clutch plate is connected to the transmission. When your foot is off the pedal, the springs push the pressure plate against the clutch disc, which in turn presses against the flywheel. This locks the engine to the transmission input shaft, making them spin at the same speed. The amount of force the clutch can hold depends on the friction between the clutch plate and the flywheel, and how much force the spring puts on the pressure plate.

When the clutch pedal is pressed, a cable or hydraulic piston pushes on the release fork, which presses the throw-out bearing against the middle of the diaphragm spring. As the middle of the diaphragm spring is pushed in, a series of pins near the outside of the spring cause the spring to pull the pressure plate away from the clutch disc. This releases the clutch from the spinning engine.

Parts description:

The Engine:

The engine runs the car. Without it working well, car won’t function. The backbone of the engine is the crankshaft, and it is the hardest working part of the engine. The crankshaft drives all belt-driven accessories, such as the water pump, the alternator, the A/C and the fan. But, it’s primary function is to change the give-and-return motion of the piston and rod into a circling motion that is transferred to the transmission, and drive wheels. As the fuel/air mixture in the cylinder burns, it forces the pistons down. Each piston is connected to the crankshaft by a connecting rod. As the piston goes down, the connecting rod causes the crankshaft to turn.

The Flywheel:

The flywheel does a lot of things – it acts as a balancer for the engine, reduces vibrations caused by cylinders firing, and it provides a smooth surface friction surface for the clutch. But the flywheel’s main function is to transfer engine torque (the turning effort produced by the pressure from the crankshaft on the pistons) from the engine to the transmission. The flywheel connects the clutch and the driveline to the engine. One side is bolted directly to the crankshaft, and one side is bolted to the clutch assembly.

The clutch disc:

Sandwiched between the flywheel and the pressure plate, the clutch disc is covered with friction material on both sides. The center of the disc – called the “hub” – is splined to match the splines on the input shaft of the transmission. Each clutch disc comes with a set of springs, located in the hub, called the torsion damper system. These springs are designed to cushion the engagement by absorbing a portion of the impact when the disc is squeezed between the flywheel and the pressure plate. In street applications, the central hub is a separate part connected to the clutch with marcel cushion springs. This absorbs any engagement impact.

The Pressure plate:

The Pressure Plate is, basically, a spring-loaded clamp that is bolted to the flywheel. The pressure plate presses the clutch disc and allows for the transfer of power to the transmission.

The Throw-out bearing:

When the clutch pedal is pressed down, this bearing – also called the Release Bearing – moves toward the flywheel. It pushes in against the pressure plate’s release fingers and moves them against the force of the plate’s springs. This action moves the pressure plate away from the clutch disc, interrupting the flow of power and reducing friction.

The clutch fork:

This piece provides a lever action to engage or disengage the clutch. It forces the throw-out bearing into the pressure plate.

The Trasmission:

The Transmission provides several selectable gear ratios, which allows the driver to match the engine output to a variety of driving conditions. starting from a dead stop – as we accelerate, the engine needs to spin quickly to make the necessary power to move the car. Once we reached the speed limit, the car needs less power to maintain speed. So, the transmission uses a high gear ratio (lots of power, but not much speed) during initial acceleration, when climbing hills. It uses a low ratio (lots of speed, but not much power) when we cruising.
