The compact design and self-increasing effect allow this clutch to transmit remarkably high torques while needing very little space, resulting in a performance factor of ca. 2.5.
Because the tension springs are easily accessible and the linings removable, the parts subject to wear are easy to replace. Because the linings are not secured to the flyweights, some noise is possible in service, but normally not sufficient to cause a nuisance.
Self-increasing effect: the profiled hub has a special form which causes a wedging effect between the profile and the flyweights when torque is applied to the clutch. This results in an additional force on the linings and allows a higher torque to be transmitted.Read More >
Flyweights are normally mounted so that they can pivot on pins , which are fitted to a flange.
There are tension springs which restrain neighbouring flyweights until centrifugal force overcomes the springforce. Then the fly weights lift from their seats and the bonded linings contact the inside diameter of the clutch drum.
Due to the asymmetric arrangement of the flyweights, the torque that can be transmitted by this type of clutch depends on the direction of rotation.
P-Type clutches are extremely narrow.
In addition, the asymmetric pivot clutch is the quietest-running clutch in the SUCO product range. For this type of clutch, the performance factor for torque transmission is ca. 1.75 or ca. 1.25 depen- ding on the direction of rotation.
Thecylindricalhub carriesthreeflyweights which are located by and can slide on cylindrical pins.Inside the flyweights,there are tension springs which restrain neighbouring 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.Read More >
