CENTRIFUGAL CLUTCH Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: drive member 1 and driven member 2 of clutch are concentric relative to each other and are connected by means of centrifugal blocks 4 provided with friction linings 5. Blocks 4 are secured in pairs to springs 3 which are secured on clutch member 1 in their turn. Flexible ring 6 located between clutch member 1 and block 4 is used for engagement with spring 3. In course of acceleration of clutch member 1, centrifugal forces acting on blocks 4 cause sagging of spring 3; at definite period of time, only separate sections are acted on by centrifugal forces, thus changing trajectory of motion of blocks 4 and enhancing smoothness of engagement of clutch members 1 and 2. EFFECT: enhanced smoothness of engagement of clutch members. 1 dwg
