This is the engaged condition when the disc touches the flywheel. The amount of working pressure applied is also determined by how much the clutch pedal is pressed. This means the amount of axial load applied by the pressure plate will reflect on the power transmitted. The following are the major parts of a clutch but there are a lot of small parts that are still featured in it:. Flywheel : this clutch part is mounted on the crankshaft, it keeps running as long as the engine is working.
A friction disc is mounted on the outer side of the flywheel. Friction disc : the friction disc could be single or multiple discs depending on its application. It is made an of material with a high coefficient of friction. The friction disc is mounted on a drive shaft. Pressure plate : the pressure plate features another friction disc on it. The pressure plate is made of special cast iron.
It is the heaviest part of the clutch assembly. The main function of the pressure plate is to establish even contact with the driven plate facing through which the pressure springs can exert a sufficient force to transmit the full torque of the engine. The pressure plate presses the clutch plate on to the flywheel from its machined surface.
Between the pressure plate and clutch cover assembly, pressure springs are fits. The pressure will be withdrawn from the flywheel whenever release levers depress by the toggle or release levers pivots accordingly. The clutch cover assembly bolts to the flywheel. It consists of a pressure plate, release lever mechanism, clutch cover, and pressure springs.
Generally, the clutch plate revolves with the flywheel. However, when the clutch has disengaged, the flywheel, as well as the pressure plates, are free to rotate independently from the driven plate and driving shaft. These pivots on pins to the clutch cover, their outer ends locate and positions on pressure plate legs, and the inner ends are projecting towards the clutch shaft.
A careful and accurate adjustment of the release mechanism is one of the most important factors governing the performance of a clutch assembly. It is a component of the gearbox. Since it is a splined shaft to the hub of the clutch plate, which is sliding on it.
One end of the clutch shaft attaches to the crankshaft or flywheel and the other end connects to the gearbox or forms a part of the gearbox.
A Clutch is defined as a system that is used to connect or disconnect the engine from the rest of the transmission elements. It is located between the engine and gearbox. During normal running and stationary position, it is always in the engaged condition. A Pilot Bearing is not present in all clutch assemblies but is most common in RWD engine configurations. This bearing sits either in the back of the crank or in the flywheel and locates the input shaft. It is important to locate the input shaft in the back of the crank for correct clutch life and operation.
Without a pilot bearing, excessive wear can occur in the splines and the hub of the driven disc, which can cause clutch release issues. ACS has a range of Clutch Kits and Flywheels to suit most automotive, commercial and agricultural applications. The clutch has several components that are key to its operation: The Flywheel has 3 main functions. Join Our Newsletter. Evenly spaced ridges, called splines , line the inside and outside of the clutch to lock into the gears and the clutch housing.
You can read more about these clutches in How Automatic Transmissions Work. An air conditioning compressor in a car has an electromagnetic clutch. This allows the compressor to shut off even while the engine is running. When current flows through a magnetic coil in the clutch, the clutch engages. As soon as the current stops, such as when you turn off your air conditioning, the clutch disengages. Most cars that have an engine-driven cooling fan have a thermostatically controlled viscous clutch — the temperature of the fluid actually drives the clutch.
This clutch is positioned at the hub of the fan, in the airflow coming through the radiator. The fluid in the clutch gets thicker as it heats up, causing the fan to spin faster to catch up with the engine rotation. When the car is cold, the fluid in the clutch remains cold and the fan spins slowly, allowing the engine to quickly warm up to its proper operating temperature.
Many cars have limited slip differentials or viscous couplings, both of which use clutches to help increase traction. When your car turns, one wheel spins faster than the other, which makes the car hard to handle. The slip differential makes up for that with the help of its clutch. When one wheel spins faster than the others, the clutch engages to slow it down and match the other three.
Driving over puddles of water or patches of ice can also spin your wheels. Gas-powered chain saws and weed eaters have centrifugal clutches , so that the chains or strings can stop spinning without you having to turn off the engine. These clutches work automatically through the use of centrifugal force. The input is connected to the engine crankshaft. The output can drive a chain, belt or shaft.
As the rotations per minute increase, weighted arms swing out and force the clutch to engage. Centrifugal clutches are also often found in lawn mowers, go-karts, mopeds and mini-bikes. Even some yo-yos are manufactured with centrifugal clutches. Clutches are valuable and necessary to a number of applications.
