Provided is a centrifugal
electromagnetic clutch. The centrifugal
electromagnetic clutch comprises a first rotating body, a second rotating body and a transmission shaft, wherein the second rotating body can rotate along with the first rotating body, power of the second rotating body is transmitted out through the transmission shaft, the second rotating body is arranged inside the first rotating body in a radial mode, and a
centrifugal clutch device is axially arranged between the first rotation body and the second rotating body, and is arranged inside the second rotating body in a radial mode. The
centrifugal clutch device comprises a plurality of
magnetism-conductive centrifugal pieces, an
electromagnetic coil, a
magnetism-conductive connecting body and a
magnetism-conductive supporting body, wherein the magnetism-conductive connecting body is fixed to the inner side of the first rotating body, and is arranged outside the
electromagnetic coil in a radial mode, the magnetism-conductive supporting body is installed on the transmission shaft, the first rotating body is fixed to the magnetism-conductive supporting body, the magnetism-conductive centrifugal pieces are distributed along the outer circumference of the
electromagnetic coil, one end of each magnetism-conductive centrifugal piece is hinged to the position between the magnetism-conductive connecting body and the magnetism-conductive supporting body, friction plates are arranged on the outer surfaces of the magnetism-conductive centrifugal pieces, wear-resistant
layers are arranged on the inner wall face, opposite to the friction plates, of the second rotating body, when the electromagnetic coil is deenergized, the friction plates are attached to the wear-resistant
layers of the second rotating body, and when the electromagnetic coil is energized, the friction plates are separated from the wear-resistant
layers of the second rotating body.
