What is the difference between dry clutch and wet clutch?

The multiple clutches have two characters that are dry clutch and wet clutch. If the clutch is operated in an oil bath, it is known as a wet clutch. If the clutch is operated dry without oil, it is known as a dry clutch. The wet clutches are commonly used in connection with, or as a part of the automatic transmission.

What is the difference between dry clutch and wet clutch?

Dry clutch: Lubricant is not applied to dry clutch and hence the torque transmitting of dry clutches is better. Dry clutches do not have oil supply and are generally single-plate. Dry clutches are used in less torque situations where frictions levels are low. The noise in dry clutch is more when compared to that of wet clutch and keeps increasing as the dry clutch continues to undergo wear and tear. Wear and tear are very much more in dry clutch. The dust particles due to wear and tear are collected in the cover of dry clutch casing. The life cycle of a dry clutch is often less when compared to that of wet clutch. Maintenance requirement and costs of a dry clutch are high. Dry clutches are generally larger in size when compared to multi-plate wet clutches. Dry clutches have a single frictional surface to transmit the power between two plates. Therefore, dry clutches do not have a much better coefficient of friction.

Wet clutch: Lubricant is applied to wet clutch to dissipate the heat from the frictional surfaces in contact. The torque transmitting capacity of wet clutch is slightly reduced due to decreased coefficient of friction between the contact surfaces due to the presence of lubricant. Wet clutches generally have multiple clutch plates and have a supply of oil to lubricate and cool the components. Wet clutches are used in high torque situations where friction levels would be high and therefore wet clutch temperatures would soar without some form of coolant. The noise level in wet clutch is less when compared to dry clutch. The presence of oil between plates of wet clutch helps in managing the noise. Wear and tear are very much less in wet clutch. The dust particles due to wear and tear are removed by the oil filter present in the wet clutch casing. The life cycle of a wet clutch is often high when compared to that of dry clutch. The maintenance requirements and cost of a wet clutch are very much low. Wet clutches are often smaller in size and generally used in applications where there is no enough space to install large single plate clutches. Wet clutches provide better coefficient of friction, as the surface area is increased due to the presence of multiple plates.  

What are the advantages and disadvantages of dry clutch and wet clutch?

Wet clutches are universal and found on most bikes. Almost 99% of motorcycles manufactured use the wet clutch. Wet clutch is bathed in oil which acts like a dampener and stops the wet clutch from knocking on itself.

• Wet clutch has less wear and tear effect due to oil circulation.

• Wet clutch has smoother engagement compared to dry clutch

• Wet clutch is cooled by engine oil

• Wet clutch tolerates slipping during initial clutch take off

• Wet clutch is cheaper to manufacture

• The wet clutch operation is quiet and makes less noise compare to dry clutch operation.

• Oil needs to be circulated specially for the wet clutch presence.

• Due to rotation of wet clutch in oil the engine losses some horse power to rear wheel

• Wet clutch garbage and hammer mixes in engine oil.

The dry clutch is almost identical to the wet clutch the only differences there are seals on the shafts that keep the oil out. In the dry clutch set up the entire clutch is outside the case of the bike. There is no oil circulated into the dry clutch, which results into dry clutch knocking on itself.

• Dry clutch is very easy to replace as it is outside the case of the bike.

• Oil does not need to circulate for Dry clutch, which ultimately eliminates reduction in loss of horse power due to oil circulation in Dry clutch.

• You can use friction modified oils in engine

• Dry clutch is easier to use.

• Dry clutch has a tendency to grab during engagement which makes take off difficult.

• The Dry clutch overheats due to grabbing effect and wears out very fast.

• The same thing makes dry clutch operation less progressive.

• Dry clutch has shorter life.

• Dry clutch is very noisy like hammering.

What are the applications of dry clutch?

Most of the motorcycles seen on the Indian roads sport only a wet clutch. Dry clutch is seen on motorcycles brands like Ducati and Moto Guzzi. The dry clutch sounds like a small tractor inside the motorcycle, but dry clutch provides better power to the rear wheels. A dry clutch delivers less drag and more power than the wet clutch, making it the favored choice in racing circles.

Dry clutch found an application where frequent engagement and disengagement is required. Dry clutch is also used where power is needed to transfer to the machines partially or fully loaded. Another typical application is in automobiles.
