On the clutch disc, what is the function of the coil springs located in its inner area?

Question

DentroTest · Accepted Answer

The clutch disc incorporates in its inner part some coil springs, also known as torsional dampers. Their function is to absorb the shocks and torsional vibrations generated by the engine at the moment of engagement and to allow the transmission of torque from the flywheel to the input shaft of the gearbox to be smooth and progressive. Keeping the pressure plate separated from the flywheel is not a job for these springs, but for the release mechanism. And keeping the two parts of the disc compressed against each other is not either: the springs do not join the parts rigidly, but allow a damped elastic torsion.
