Construction and mode of operation
The cylindrical hub carries three flyweights which are located by and can slide on cylindrical pins . Inside the flyweights there are tension springs which restrain neighboring flyweights until centrifugal force overcomes the spring force. Then the flyweights lift from their seats and the linings on the flyweights contact the inside diameter of the clutch drum. Friction between the linings and the clutch drum allows torque to be transmitted.
