Pavement roller oscillation device controlled by electromagnetic clutch

The invention relates to a pavement roller oscillation device controlled by an electromagnetic clutch. A power transmission mechanism consists of a driving pump, a transmission shaft, an electromagnetic clutch and a drive pulley, wherein the drive pulley is arranged on the electromagnetic clutch and is opposite to an end cover of the electromagnetic clutch; an eccentric oscillation mechanism comprises an eccentric oscillation shaft and a driven pulley; a body of the eccentric oscillation shaft is of a cylinder shape; the shaft body is internally provided with a sliding groove which is parallel to the axial direction of the shaft body; an opening of the sliding groove is formed in the circumferential surface of one side of the shaft body; the sliding groove is internally provided with an eccentric sliding block; the bottom end of the eccentric sliding block is connected with the bottom of the sliding groove by an extension spring; and when the extension spring is in a reset state, the center of gravity of the eccentric oscillation shaft formed by the eccentric sliding block and the shaft body is positioned on the axis of the shaft body. The driving pump of a pavement roller is taken as a power source of the oscillation device, so that the effects of saving the space and reducing the cost can be realized; and the eccentricity degree of the eccentric oscillation mechanism can automatically change along with the rotating speed, so that the eccentric oscillation mechanism can be gently started, and the oscillation is rapidly stopped.
