New magnetic suspension train travelling mechanism

Abstract

The new magnetic suspension train traveling mechanism includes cross beam, longitudinal girder, bracket, electromagnet, linear driving motor, cross beam connector, and buffering spring seat. The longitudinal girder capable of being twisted and the cross beam are connected together, the electromagnet has its one end connected to the cross beam and has its two ends connected via hinges to electromagnet bracket and the electromagnet has the structure of integrated beam. The present invention has improved mechanical decoupling performance and bent track passing capacity, reduced weight, simple structure and raised safety redundance.

Description

technical field [0001] The invention relates to a device for a conventional magnetic levitation train, in particular to a novel running mechanism of a magnetic levitation train. Background technique [0002] When the maglev train travels along the track, the electromagnet must track the track. The electromagnets on both sides of the running mechanism are in the form of a straight line, forming a parallelogram on the straight track, a sector on the curve, and a radial curved surface on the transition curve. Therefore, the running mechanism is the key structure of the maglev train, which determines the ability of the maglev train to pass through curves and transition curves, and also directly determines the mechanical decoupling characteristics of the train. At present, there are two more advanced structural forms: Japan's medium and low-speed maglev train running mechanism; Germany's high-speed maglev train running mechanism. [0003] Japan's medium and low speed maglev trai...

Problems solved by technology

[0006] The suspension electromagnet is connected to the running mechanism through a very rigid spring, which weakens its role as the load-bearing structure of the running mechanism, making the longitudinal beam the main longitudinal load-bearing part, which weakens the important function of the longitudinal beam torsion coupling. The changes of front, back, left and right are all coupled with each other through electromagnets and longitudinal beams. The structure is too rigid, the torsional performance is poor, and the mechanical decoupling characteristics are poor. The requirements for suspension control and track accuracy are very high, and small radius curve

At the same time, a large number of metal rubber parts are used, which is not good for later maintenance

[0007] Both can only place linear propulsion motors on both sides, and the flexibility of the structure is affected
