Abstract

The present invention provides a multiple effect combined magnetic levitation shock absorber, comprising a fixed metal base, a hollow metal cylinder and a metal axle, wherein the fixed base comprises an iron core having a top face in which a permanent magnet is embedded, the core being surrounded by electromagnetic windings, which once being energized, causes an electrical current that is converted into a magnetic field. The hollow cylinder is arranged on and fixed to the fixed base and has a bottom end into which the permanent magnet of the iron core is fit and a top end that is open for the insertion of a bottom end of the axle. The bottom end of the axle is fit into the cylinder and is provided with a permanent magnet in an interior closed to the bottom end, a top end of the axle located above the cylinder and forming a small platform. By means of the above construction and employing a feedback control system to control the current flowing through the electromagnetic windings, when a weight is positioned on the platform, the permanent magnet inside the axle and the cylinder cause magnetic hysteresis and thus damping effect therebetween. A stable mutual-repulsive electromagnetic force is induced between the permanents of the axle and the fixed base to reduce violent displacement of the axle. The electromagnetic field induced by the energization of the electromagnetic windings of the fixed base counteracts external disturbance and realizes efficient suppression and elimination of vibration, thereby effecting shock absorption.
