Which type of spring is commonly found in a diaphragm clutch?

A diaphragm clutch commonly incorporates a diaphragm spring, which is a specific type of coil spring. This diaphragm spring functions to engage and disengage the clutch, providing a consistent and reliable way to apply force. Its shape allows for a larger surface area to be in contact with the clutch disc, ensuring efficient power transmission from the engine to the transmission.

The design of the diaphragm spring enables a lighter pedal feel for the driver while still maintaining a strong engagement force. This is particularly effective in providing a smooth and gradual clutch engagement, which enhances driving comfort. The structure and functionality of the diaphragm spring make it an ideal choice for modern clutch systems, as opposed to other types like helical springs, leaf springs, or torsion springs, which do not offer the same benefits in this application.
