Clutch

A clutch is a device that transmits power intermittently by coupling and uncoupling two separate rotating bodies. Clutches function to transmit torque from an engine to a drivetrain and deliver power smoothly for vehicle movement. Common types of clutches include manual, hydraulic, electric, and centrifugal clutches.

Clutches:

A clutch is a frictional device whose primary function is to transmit power intermittently.

A clutch is a device that is used to couple and uncouple two separate bodies of rotation. These two
separate bodies may consist of shafts, gears and sprockets, a prime mover or motor, or any combination
of these.

Function of the Clutch

Function of transmitting the torque from the engine to the drivetrain.

Smoothly deliver the power from the engine to enable smooth vehicle movement.

Perform quietly and to reduce drive-related vibration

Formula: same as collar bearing

Friction clutches rely on the principle of friction. The friction between the driving component shaft and
the driven component shaft when they are engaged (i.e., brought into contact) allows the rotational
energy to transfer from the former to the later

Some of the most common types of friction clutches are:

Manual clutches. Manual clutches must be engaged and disengaged by the machine operator. They are
suitable for applications where engagement and disengagement must occur at a specific or consistent
rotational speed.

Hydraulic clutches. Hydraulic clutches utilize hydraulic fluid (e.g., oil) to extend and retract pistons,
which engage and disengage the clutch. They are suitable for hydraulic systems where engagement and
disengagement must occur at a specific or consistent rotational speed.

Electric clutches. Electric clutches convert electrical energy into mechanical energy. The electrical power
source passes a current, which generates an electromagnetic field. The generated electromagnetic field
then attracts a pressure plate, which engages the clutch. The clutch disengages when the power source
stops passing a current. These clutches are suitable for use in applications where engagement and
disengagement must occur at a specific or consistent rotational speed and with a readily accessible
power source.

Centrifugal clutches. Centrifugal clutches automatically engage and disengage when the proper
rotational speeds are achieved. They are suitable for applications requiring engagement and
disengagement at moderate or inconsistent rotational speeds.
