Abstract
A centrifugal clutch having a rotor, a clutch component, and at least one centrifugal weight movable relative to the rotor. When the rotational speed of the rotor is below a predefined value, the centrifugal weight is in a first position and at a distance from the clutch component so that the rotor can rotate freely relative to the clutch component and, when the rotational speed of the rotor is above a predefined value, the centrifugal weight executes a movement relative to the rotor under a centrifugal force into a second position so that the centrifugal weight produces a mechanical force fit between the rotor and the clutch component. The centrifugal weight has first toothing and the clutch component a second toothing so that the first toothing, above the predefined rotational speed, engages into the second toothing, establishing a form-locking connection between the rotor and the clutch component.
