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

In a diaphragm clutch, the commonly used spring is a coil spring. The diaphragm spring is engineered to provide a consistent force across the entire clutch surface, which is crucial for engaging and disengaging the clutch smoothly. Unlike other types of springs, the design of a coil spring in this context allows it to maintain a specific load with minimal effort, providing a high level of responsiveness and reliability.

The coil spring’s characteristics enable it to expand and contract efficiently, which is necessary for the operation of the clutch mechanism as the driver presses and releases the clutch pedal. This ensures that the clutch engages and disengages efficiently, enhancing the performance and drivability of the vehicle. Thus, the use of a coil spring in the diaphragm clutch is pivotal for effective gear shifts and overall operation of the manual transmission.
