A clutch is a mechanical device that engages and disengages power transmission.In a motor vehicle, the clutch acts as a mechanical linkage between the engine and transmission, and briefly disconnects, or separates the engine from the transmission system. This disconnects the drive wheels whenever the clutch pedal is depressed, allowing the driver to smoothly change gears.
Have you ever wondered what is happening inside a car when you press the clutch pedal? Or why do you need to press the clutch pedal before you shift gears in a manual transmission car? This video gives you logical answers to these questions. At the end of the video, we will also understand the crucial role played by the clutch in an uphill start.
When a car is moving under power, the clutch is engaged. A pressure plate bolted to the flywheel exerts constant force , by means of a diaphragm spring, on the driven plate .he plate has friction linings, similar to brake linings, on both its faces. This allows the drive to be taken up smoothly when the clutch is engaged.
When we completely press the clutch pedal, the movable friction disc slides back on the shaft. This is the disengaged condition in which the friction doesn’t touch the flywheel.When we completely release the clutch pedal, the movable friction disc slides forward on that shaft. This is engaged condition in which the disc has completely touched the flywheel.
