GUIDE APPARATUS FOR ATTRACTION TYPE MAGNETIC LEVITATION CAR

摘要

PURPOSE:To make the title car pass on the curve of a track having a small radius of curvature, and to obtain a guide apparatus having small excitation loss from a viewpoint of overall line length by installing a guide electromagnet to a truck through a hydraulically controlled moving plate as a clearance control means. CONSTITUTION:The spring energizing force of a compression spring 18 and magnetic attraction force working between a guide electromagnet 3 and a guide magnetic rail 6 are applied to a moving plate 14, and the moving plate 14 travels on the rectilinear section of a track while holding minimum void length Gmm regulated by a stopper 16A. When a hydraulic pump is driven before the title car approaches to a curve and a hydraulic system 12 is driven to the anti-track side, void length G is extended. Consequently, a marker on the track 4 is read or the output signal of an oscillator, etc., on the track is received, thus controlling the hydraulic pump. Accordingly, void length G can be expanded in response to the radius of curvature of the curve only at the time of the passage of the curve.
