Types Of Clutches
Before starting to study about different types of clutch, we must know about the meaning of clutch. 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 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.
Friction clutches:
These clutches works on the principle of friction exist in between two rotating shaft when they come in contact with each other.
virtue of friction developed between contacting surface. The friction surface is typically flat and perpendicular to the axis of rotation. Two or more surface is pressed together by using compression spring. The friction force is used to bring the driven shaft to the proper speed gradually without excessive slipping. The major types of friction clutches are plate clutch, cone clutch, centrifugal clutch.

- Frequent engagement and disengagement is possible.
- Smooth engagement and minimum shock during the engagement.
- Friction clutch can be engaged and disengaged when the machine is running since they have no jaw or teeth.
- Easy to operate.
- They are capable of transmitting partial power.
- Friction clutch can act as a safety device. They slip when the torque exceeds a safe value, thus safeguards the machine.
Applications of friction clutches:
Friction clutch found an application where frequent engagement and disengagement is required. It is also used where power is needed to transfer to the machines partially or fully loaded. Another typical application is in automobiles.
Fluid flywheel:
Fluid flywheel clutches works on transfer of energy from one rotor to the other by means of some fluid.
