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? In order for a car to stop without killing the engine, the wheels need to be disconnected from the engine somehow. The clutch allows us to smoothly engage a spinning engine to a non-spinning transmission by controlling the slippage between them.
In the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). In these devices, one shaft is typically attached to an engine or other power unit (the driving member) while the other shaft (the driven member) provides output power for work.
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 you press the clutch pedal, the clutch disengages, thus removing the connection between the engine and transmission.
This allows the driver to shift gears. When the clutch is disengaged, the vehicle will not move forward even if the accelerator pedal is pressed as the engine is now disconnected from the transmission.The clutch is generally in the form of a friction disc that provides a coupling by means of friction./Learn Engineering
