What is a clutch friction plate made of?

Materials. A common friction material is an organic compound resin with a copper wire facing or a ceramic material. Ceramic materials can often transmit higher torque loads, but they can cause increased wear rates of the flywheel.

What are properties of a friction material of a clutch?

It exhibits good take-up characteristics. It has good centrifugal strength to withstand lining disintegration due to sudden acceleration caused during the changing of gears. It has stable rubbing properties at high operating temperatures.

Which friction clutch is used in two wheeler wet or dry?

There are two types of clutches — wet and dry: Wet clutches are used in almost all bikes. They are bathed in engine oil, to cool the clutch components, but this causes a fluid drag that saps the engine power. Dry clutches are noisier and have a shorter life due to the absence of oil, but aren’t affected by fluid drag.

What is multiplate wet clutch?

Wet clutches, in general, have multiple clutch plates (in cars) and have a supply of oil to lubricate and cool the components. This type of clutch is located inside the engine casing. The wet clutches are greatly amplified and therefore can cope with much higher torque inputs.

What is the best material for a clutch?

Kevlar clutch discs have two key benefits: they’re incredibly durable, and they always engage the flywheel smoothly. They last 2-3 times longer than clutch discs made of organic materials. These are the ideal choice for machines that require smooth, precise movement.

What is material for clutch facing?

Clutch facings can be manufactured from a range of materials depending on application and some of the most common are asbestos, woven fibers such as Kevlar or aramid and ceramic materials. As with disc brake pads and other clutch materials, the materials used in clutch facings need to be durable.

What is the material for clutch facing?

What is clutch lining material?

Your clutch lining material will be Organic, Ceramic, Kevlar or Feramalloy. Kevlar like organic needs a fairly high clamping force due to it having a similar co-efficient of friction to organic. Its advantage is its ability to withstand heat. Often Kevlar is able to withstand 40-50% more heat than organics.

Which clutch is known as wet clutch?

Thus, a large amount of heat generation requires cooling to maintain functionality therefore multi-plate clutches are considered as wet clutch while single plate clutches are considered as dry clutches.

What is dry clutch and wet clutch?

The purpose of a dry clutch is the same as a wet clutch. The only difference between the two types of clutches is that the dry ones aren’t covered in oil. Without the oil, the clutch can’t stay as cool, which causes dry clutches to be noisier and wear out more quickly.

What is the material used in the clutch cable mechanism?

A clutch cable uses a steel cable inside a flexible housing to transfer pedal movement to the clutch fork. This is a simple mechanism. The cable is usually fastened to the upper end of the clutch pedal. The other end of the cable connects to the clutch fork.

What is a wet multi-plate clutch?

A wet multi-plate clutch is an assemblage of steel driven plates and compound organic resin friction plates housed in a drum and spinning concentrically on a shaft. With respect to a “wet” clutch, the assembly is cooled by a limited amount of oil.

How many plates are in a clutch assembly?

Usually, the clutch assembly is composed of six of each type of plate that are alternately stacked (steel, friction, steel, friction, etc; see diagram below). But there might be more or fewer plates (5/5 or 7/7).

How do clutch plates engage/disengage?

The clutch plates are generally engaged/disengaged via a pushrod or some other lifting mechanism. One set of plates engages with the outer drum, and the other set of plates engages with the inner hub. Note the “tangs” on the plates.

How does a wet clutch work?

With respect to a “wet” clutch, the assembly is cooled by a limited amount of oil. The same basic arrangement/assembly is sometimes used in a “dry” drum; i.e. without being exposed to oil.
