PURPOSE:To obtain the effect of the reduction of the weight of trucks corresponding to the decrease or more of electromagnetic force by forming a truck group in the same manner as the arrangement of magnetic poles, one pole thereof is removed at every three poles, through the arrangement of magnetic poles at regular intervals in the truck group through series coupling. CONSTITUTION:The three trucks 2 are installed to a car body 1, and supported through air springs 4. Sections among the car body and the trucks are connected by means of anchors 5. Superconducting electromagnets are arranged in order of NS and SN and in shape that poles at every two pole are thinned out in the arrangement of the superconducting electromagnets to be continuously disposed in order of NS, NS and NS originally. Consequently, electromagnetic attenuation hardly differs from one in case of continuous arrangement, energy supplies can be economized by the reduction of the weight of the truck, the rates of sections upper than the springs are increased in the weight ratio of the sections upper than the springs to sections lower than the springs, periodic damping action is improved, and the mutual clearances of the trucks are extended. Accordingly, space in which the front and rear guide wheels of the truck are disposed can freely be formed while space in which flow-regulating covers regulating air flows among the trucks are arranged can be obtained. |
