What is the Clutch:

In an automobile, a gearbox is required to change the speed and torque of the vehicle according to the driving requirement.

If we change a gear, when the engine is engaged with the gearbox or when the gears are in running position, then it can cause of wear and tear of gears.

To overcome this problem a device is used between gearbox and engine, known as the clutch.

Clutch is the first element of a powertrain. The main function of the clutch is to engage and disengage the engine to the transmission. when the driver needs or during shifting of gear.

When the clutch is in engage position, the power flows from the engine to the wheel and when it is in a disengaged position, the power is not transmitted.

The principle of clutch:

When two revolving friction surfaces are brought into contact and pressed, then they are united and start to revolve at the same speed due to the friction force between them.

This is the basic principle of a clutch. The friction between these two surfaces depends on the area of a surface, the pressure applied to them and the friction material between them.

The driving member of a clutch is the flywheel mounted on the engine crankshaft and the driven member is a pressure plate mounted on the transmission shaft.

Some friction plates, sometimes known as clutch plates are kept between these two members. This whole assembly is known as the clutch.

The function of the clutch:

The Following Function of an Automobile Clutch:

1. It can be disengaged. This allows engine cranking and permits the engine to run without delivering power to the transmission.

2. While disengaging, it permits the driver to shift the transmission into various gear according to operating condition.

3. While engaging, the clutch slips momentarily. this provides smooth engagement and lessens the shock on gears, shaft and other parts of an automobile.

4. While engaging, the clutch transmits the power to the wheel without slipping, in ideal condition.

  1. Hae,am just interested in the field of mechanics and this site is real helpng myself to get more knowledge in mechanics,,am still a learner,, I really do thank you alot,,but I had one question which I wanted to ask,, when is the time the clutch is engaged or disengage when is switched on or off?? Have tried to join your WhatsApp group but is full,,
