Background technology:

Existing magnetic suspension train is divided into often leads type and superconduct two big classes.The type of often leading also claims normal magnetic conduction suction type, is representative with the Germany floating train transrapid of at a high speed normal magnetic conduction, and it is to utilize the principle of conventional DC electromagnet electromagnetic attraction that train is hanged, and the air gap of suspension is less, is generally 10 millimeter.The speed of often leading the type high-speed maglev train can reach per hour 400～500 kilometers, is suitable for intercity length apart from fast traffic.And the superconduct magnetic suspension train also claims the superconduction magnetic expelling type, with Japanese MAGLEV is representative, it is the high-intensity magnetic field that utilizes superconducting magnet to produce, during train operation be arranged in ground coil mutual action, producing electrodynamic repulsion force hangs train, suspension air gap is bigger, is generally 100 millimeter, and speed can reach per hour more than 500 kilometers.Although magnetic suspension train has above-mentioned many advantages, but still come with some shortcomings: (1) is because magnetic suspension system is finished suspension, guiding and driving function with electromagnetic force, braking problem after this has a power failure with regard to problem, the especially train that exists in outage back magnetic suspension safety control remains the problem that will solve; (2) hoverheight of normal magnetic conduction suspension technology is lower, and is therefore higher than superconductor technology to the requirement of planeness, subgrade settlement amount and the switch structure aspect of circuit; (3) the super-conductive magnetic suspension technology is because the normal waveguide technology of eddy effect suspension energy consumption is bigger, and cooling system is heavy, and high-intensity magnetic field is also all influential to human body and environment; (4) adopt linear motor driving, drive efficiency is lower, and the control difficulty is bigger.

Summary of the invention:

The purpose of this invention is to provide a kind of magnetic suspension thruster.The present invention can solve the maglev safety control problem in existing magnetic suspension train outage back, the normal lower problem of magnetic conduction suspension technology hoverheight, and the bigger problem of super-conductive magnetic suspension technology suspension energy consumption.It is made up of dynamic assembly 1, first support wheel 2, second support wheel 3, first rail 4, second rail 5, base 6, first magnet pulley 7, second magnet pulley 8, the first induction guide rail 9, the second induction guide rail 10; First support wheel 2 is socketed in the middle part of the rotating shaft 1-1 left-hand end of dynamic assembly 1, second support wheel 3 is socketed in the middle part of the rotating shaft 1-1 right-hand end of dynamic assembly 1, the bottom of first rail 4, the bottom of second rail 5 all is connected on the upper surface of base 6, and make the periphery of first support wheel 2, the periphery of second support wheel 3 respectively with the upper surface of first rail 4, roll and connect in the upper surface of second rail 5, first magnet pulley 7 is socketed on the termination, rotating shaft 1-1 left side of dynamic assembly 1, second magnet pulley 8 is socketed on the termination, rotating shaft 1-1 right side of dynamic assembly 1, the first induction guide rail, 9 bottoms, the bottom of the second induction guide rail 10 all is connected on the upper surface of base 6, and makes the periphery of first magnet pulley 7, the periphery of second magnet pulley 8 place respectively first the induction guide rail 9 directly over, directly over the second induction guide rail 10.

The present invention has the following advantages:

1, lift force can self adaptation, self-stabilization, do not need special lift force control setup, therefore not only control simply, safe and reliable, and cost is low, operating efficiency is high;

2, suspension air gap is big, and lift force and propulsive force are stable, and has removed the requirement to guides with high precision from;

3, control owing to adopting on the car, can use for reference the control technology of High-speed Wheel, therefore the converters quantity that needs is few, and the feasible reliability low, system of controlling cost improves.
