CENTRIFUGAL CLUTCH Centrifugal clutch is being increasingly used in automobiles and machines. Obviously, it works on the principle of centrifugal force. The driving shaft carries the spider, sliding shoes and springs while the driven shaft is connected to the pulley, as shown in Fig.7.9. The sliding shoes are mounted radially and springs keep them away from inner rim of the pulley. Shoes have some mass. As the speed of the driving shaft rises the centrifugal force on the shoes increases causing them to move radially outward within the guides provided. When the centrifugal force is less than the spring force, brake lining cannot make any contact with the pulley rim. But when the centrifugal force is equal to the spring force, the shoe is just floating, when the centrifugal force just exceeds the spring force, the shoe moves outward and comes into contact with the driven member and presses against it to transmit the torque.
