Description
Technical field
The present invention relates to a kind of normal magnetic conduction aerotrain device, especially a kind of later-model magnetic suspension train running mechanism.
Background technology
When magnetic suspension train was advanced along track, electromagnet must be followed the tracks of track, and the electromagnet of running mechanism both sides is a form of straight lines, formed a parallelogram on straight way, was one fan-shaped on the bend, was an oar curved surface on the junction curve.Therefore running mechanism is the key structure of magnetic suspension train, and it has determined the bend of magnetic suspension train and the carrying capacity of junction curve, has also directly determined the mechanically decoupled characteristic of train.At present advanced version has two kinds: in the Japan, low speed magnetic suspension train running mechanism; The high-speed maglev train running mechanism of Germany.
Japan in, low speed magnetic suspension train running mechanism, as shown in Figure 7, it mainly comprises: two girder unit 72, be coupled as one by two groups of anti-roll beams 71 in four front and back and suspending rod 75, discrete levitating electromagnet 73 is loaded on 72 belows, girder unit, and linear advancement motor 74 is loaded on 72 middle parts, girder unit, and two girders of this structure are independently substantially, can make the electromagnet that is loaded on it follow the tracks of two tracks respectively and be independent of each other, realize the traveling function.
