PROBLEM TO BE SOLVED: To provide an electromagnetic suspension equipment that a fine damping force is obtained in all the ranges of expansion actuation (stroke) and a miniaturization can be done. SOLUTION: A hydraulic damper 21 produces the big damping force in the stroke range at the end side, while the electromagnetic damper 20 usually generates the damping force (propulsion force) in the stroke range. Even if the damping force (propulsion power) generated by the electromagnetic damper 20 becomes lower in the stroke range at the end side, the synthesized damping force (addition power) obtained by synthesis with the damper force (propulsion power) becomes big value. Thereby, fine propulsion power/damping force (addition power) can be obtained in all the range of the expansion actuation (stroke). Even if a magnet 7 is placed on the central side of the stroke, fine propulsion power/damping force (addition power) can be obtained in all the stroke ranges and the equipment can be miniaturized as the magnet 7 is arranged on the central side of the stroke. |
