Adding plates to the Cuttack to create a multi-plate clutch will increase the torque capacity of the clutch without increasing the spring strength or clutch diameter. As the number of clutches plate increases, the number of friction surfaces will also increase, and hence the torque transmitting capacity of the clutch also increases.

The small-size multi-plate clutch delivers nearly double torque compared to a single plate clutch of diameter. As we know, the clutch is the most important integral part of a power train as it is used to shift the drive from the engine shaft to the transmission shaft to the required torque or speed output, but what is the need for a multi-plate clutch.

Where high torque output is required, like a pickup truck, a single plate clutch fails to provide the much frictional force (between the flywheel and clutch plates) that is required to provide such high torque, Therefore in a heavy vehicle such as a pickup truck multi-plate clutch is used.

Motorcycles have space problems due to their small size, so a multi-plate clutch with smaller clutch plates meets the required torque output requirement instead of a larger single-plate clutch.

• Increased torque transmission capacity could be obtained.
• The diameter is reduced as it has more friction surface which reduces the size of the clutch assembly.
• It is highly reliable.
• It is suitable for heavy vehicles.
• Increase in better acceleration.
• Decrease the weight of the clutch.
