FREEWHEEL CLUTCH Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: freewheel clutch has sleeve with inner cylindrical surface, inner half-clutch formed as double-sided eccentric with cam in its middle part, wedging members formed as eccentric bushings with outer arced projections inserted between sleeve and inner half-clutch. Slots are cut in inoperative parts of eccentric bushings transverse of their width to define inner thrusts. Projections may be pressed to each other for defining space between bushing and sleeve. Clutch has coil spring for biasing eccentric bushings with their arced projections to sleeve surface, centrifugal cam loosely mounted on pin fixed in wall of one of eccentric bushings. Centrifugal cam has bead and eccentric cam has slot and beveled part engageable with centrifugal cam bead. EFFECT: increased efficiency and enhanced reliability in operation of freewheel clutch. 4 dwg
