What is a coil spring clutch?

A coil spring clutch is a type of mechanical device used to engage and disengage power transmission in machinery, typically found in vehicles. It utilizes coil springs to apply pressure to a friction disc, allowing it to connect or disconnect from the driving shaft. When engaged, the springs compress to hold the disc tightly against a flywheel, enabling power transfer; when disengaged, the springs relax, allowing the disc to spin freely. This design is known for its simplicity and effectiveness in controlling torque and rotational motion.
