Before starting to study different types of clutches, we must know about the meaning of a clutch. A clutch is defined as the device which is used in automobiles to transmit power from one rotating shaft to another shaft. In cars, it transmits power from the flywheel connected to the engine shaft to the clutch shaft, and from the clutch shaft, it is transmitted to the rear wheels through gear shaft, propeller shaft, and differential.

Mainly clutches are divided into 2 parts:
- Friction clutches and
- Fluid flywheel
These clutches works on the principle of friction exist in between two disc when they come in contact with each other. They are mainly used in the automobile sector such as in cars, motorcycles, buses, trucks, etc.
Working Principle of friction clutches
Now lets us take two-disc, first one is named D1 and the second one is D2. Disc one is rotating and disc D2 is not rotating. Move disc D1 near D2 until they will make contact with each other. Now you will see that the disc D2 also starts rotating with disc D1. And this is possible because of the friction force that exists in between the two-disc when they came in contact with each other. On the same principle, the friction clutches work.
Working principle of Fluid Flywheel clutches
Types of friction clutches:
- Cone clutch
- Single plate clutch
- Multi-plate cutch
- Semi-centrifugal clutch
- Centrifugal clutch
