In the clutch disc, the central or inner area incorporates a series of coil springs. What is their main purpose?

Question

DentroTest · Accepted Answer

The torsion springs located in the inner part of the clutch disc perform an essential damping function. When the clutch pedal is released to connect the engine with the transmission, the connection between the flywheel and the input shaft of the gearbox produces strong torsional jolts. These springs compress briefly to absorb that initial shock and dampen the vibrations, making the transmission of torque gradual, smooth and progressive. Keeping the disc permanently disengaged from the pressure plate is not their function, because separating the disc is the job of the pressure plate operated by the release bearing. Joining the two sections of the disc in a fixed and compressed way is not either, because the springs do not compress the parts rigidly but provide torsional elasticity.
