Abstract
A centrifugal frictional clutch is constituted by a rotary housing supporting for rotation a weight lever actuated by the centrifugal force and being biased by a spring against the latter. The weight lever pivotably supports a coupling jaw which cooperates with a frictional surface of a coupling disk. The resultant normal frictional force F.sub.N forms with the line connecting pivot points of the jaw and of the lever a design angle .gamma. which corresponds to the angle of the static friction. The biasing spring, the jaw and the weight lever are arranged within the range of the coupling disk. Preferably, the clutch includes an additional disk having a smaller diameter and coupled via a free-wheel coupling to the first coupling disk to act as a double speed clutch.
