CENTRIFUGAL TWO-SPEED CLUTCH Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: driving clutch part 1 and driven clutch part are mounted for permitting interaction with friction linings 5 and 7 by way of blocks 4 and 6. Blocks 4 are coupled with clutch part 1 through plate springs 8. Blocks 6 are connected with clutch part 1 through spring 10. Springs 8 and 10 are inclined to the plane containing the axis of the clutch and lateral axis of symmetry of blocks 4 and 6. Springs 8 are provided with centrifugal weights 9 secured to its free ends. Depending on real speed of rotation of clutch part 1 under the action of centrifugal forces, blocks 4 or blocks 6 are set in operation. When blocks 6 are in operation blocks 4 are locked by way of weights 9. EFFECT: enhanced reliability. 2 dwg
