Difference between Wet Clutch vs Dry Clutch

What Is a Wet Clutch?

What Is a Dry Clutch?

What Are the Differences Between Dry and Wet Clutches?

The following table includes the differences between dry and wet clutches. It will provide a better overview of these two.

Criteria

Wet Clutches

Dry Clutches

Oil lubricant

Such clutches come with engine oil, which acts as a lubricant spread all over it.

These clutches are free of engine oil and do not contain any lubrication.

Type of plate

You can find vehicles with a wet multi-plate clutch, as the clutch has oil to cool down all the plates.

There is no oil supply between the plates; hence, such clutches are usually single-plate.

Torque transmission type

Such clutches are ideal for high-torque situations undergoing high friction levels.

They are ideal for lower torque situations, whereby the friction level is relatively low.

Noise

The level of noise between the plates is relatively lower. This is mainly because the oil between the plates helps avoid vibration.

The noise levels are relatively higher compared to wet clutches, which can increase with wear and tear.

Wear and tear

Such clutches ensure lower wear and tear, as the lubricant protects the clutch from being exposed.

With such clutches, there are higher chances of wear and tear, as there is no protection available.

Dust accumulation

There is a higher possibility of dust accumulation with such clutches, as these are covered with oil. However, the oil filter controls the dust.

There is a lower possibility of accumulation of dust particles here, as the clutch is dry. However, there is no oil filter here.

Life cycle

Such clutches offer a higher life cycle, lower wear and tear risks, and great protection.

The life cycle of such clutches can be lower, as these are more vulnerable to wear and tear with time.

Maintenance

There is a lower requirement for regular maintenance in such clutches.

You need to regularly maintain such clutches, which can be expensive.

Coefficient of friction

With the presence of multiple plates, the surface area is increased in such clutches. Thus, they offer a better coefficient of friction.

Such clutches come with a single frictional surface, which is used for transmitting power between two plates. The coefficient of friction is, therefore, low.
