How does a centrifugal clutch work? What is a centrifugal clutch? Centrifugal clutches are used in go karts, mopeds, chain saws, lawn mowers, and many other small engine powered devices. They work by using the principle of centrifugal force to have a clutch shoe apply a friction pad against the clutch housing, thus rotating a device which requires torque to run. At idle speed, springs hold the clutch shoes in so that there is no torque transfer to the clutch housing.
