CENTRIFUGAL CLUTCH Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: centrifugal clutch has first half-coupling with airtight cavity which may be filled with hydraulic fluid and eccentrics positioned coaxially. Two-arm levers are hinged to first half-coupling, one of arms contacting the respective eccentric. Other arms of levers are centrifugal weights. Hydraulic damping unit includes hydraulic resistors positioned on peripheral part of airtight cavity. Centrifugal clutch also includes freewheel clutch and its holder is connected rigidly to second half-coupling. Hydraulic resistors are mounted for rotation on axle parallel to clutch axle. They are provided with projections which offer resistance to hydraulic fluid flow. Second half-coupling carries flywheel. Eccentrics are connected rigidly to second half-coupling. Two-arm levers are preferably directed with centrifugal weights towards side of half-coupling rotation. EFFECT: reduced noise, vibration and inertia. 6 cl, 5 dwg
