CLUTCHES

 

   A clutch is a mechanical device that engages and disengages power transmission, especially from a drive shaft (driving shaft) to a driven shaft. 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 and other to power unit (the driving member), while the other shaft (the driven member) provides output power for work. Typically the motions involved are rotary, but linear clutches also exist.

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.
Functions of a 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.
  • Protect the drivetrain when given the inappropriate use. Given the situation, the clutch will fail when given the inappropriate use in turn to protect the rest of the drivetrain, similar to the function of an electric fuse.
