The magnetic suspension mechanism can be used for constant-conductive high-speed and a middle-low-speed magnetic-levitation trains, and has the advantages that: the structure of the magnetic-levitation train can be greatly simplified, the weight of the vehicle can be reduced, and the system efficiency is high.
Description
Technical field
The present invention relates to magnetic levitation vehicle equipment, especially often lead the magnetic floating mechanism manufacturing field of equipment of the integrated suspension guiding traction function of type magnetic suspension train.
Background technology
The floating train of normal magnetic conduction is at a high speed or middle idling slow speed system all relates to suspension, guiding and straight line traction link.In the floating system of the normal magnetic conduction of existing high speed, suspend and all realize with the long stator synchronous dynamo with traction: the stator that namely is installed in the long stator synchronous linear motor on the ground rail beam is realized suspending with the mover (being levitating electromagnet) that is installed in the motor on the floating car of magnetic; Give when passing through balanced three-phase current in the stator winding of motor, stator winding produces travelling-magnetic-field, and it and electric mover magnetic fields produce longitudinal traction power.For making the floating car of magnetic can be positioned at track centre and can pass through bend, existing high-speed magnetic floating car has additionally increased the electromagnetism guidance system, and it is actual to be another to (or many to) electromagnet, makes train be positioned at all the time track centre by the control to electromagnetic force.The adding of electromagnetism guidance system has increased the complexity of the floating car of magnetic, has also increased the weight of train, the design of giving train, and the installation of equipment has increased difficulty, has reduced the reliability of train.
Existing middle low-speed maglev train levitating electromagnet adopts U-shaped structure.Like this, the guiding problem of train has obtained solution naturally, in case because vehicle generation transverse shifting, vehicle-mounted levitating electromagnet will produce displacement with the U-shaped iron yoke that is installed on the ground rail beam, air-gap field will produce a restoring force, make magnetic float the car automatic centering.So it does not need extra guiding link.But the linear asynchronous traction motor of short stator is adopted in the traction of train, and it and electromagnetic suspension system have nothing to do.Because the magnetic circuit ﹠ circuit of line inductance electromotor is discontinuous, when motor moves, will produce so-called " end effect " in the air-gap field of motor.End effect has greatly reduced the efficient of traction electric machine.Because the working gas gap of line inductance electromotor is large, the loss of motor is very large simultaneously.Because motor and inverter are installed onboard, vehicle from great, the power that consumes of suspending is large, system effectiveness is low.
Summary of the invention
In view of the deficiency of the existing program of above statement, the purpose of this invention is to provide the normal magnetic conduction suspension mechanism that a kind of integrated suspension guiding traction function is integrated, make it to overcome the above shortcoming of prior art.
The objective of the invention is to propose and realize based on following analysis and scheme:
The magnetic floating mechanism of integrated suspension guiding traction function realizes that by the stator that is installed in the long stator synchronous linear motor on the ground rail beam and the mover that is installed on the floating car of magnetic as the motor of levitating electromagnet normal conductive magnetism suction suspends.The iron core of the stator of long stator synchronous linear motor be provided with in opposite directions many wide non-ferromagnetic longitudinal slots as symmetry on the iron core of the mover of the motor of levitating electromagnet.
The invention provides the normal magnetic conduction suspension mechanism that a kind of integrated suspension guiding traction function is integrated, during the mechanism transverse shifting, mechanism produces the electromagnetism reset force automatically, forces the stator of long stator synchronous dynamo to align with the line of centers unshakable in one's determination of mover, thereby guarantees that this mechanism is in correct position.Can be used for often leading type at a high speed with middle low-speed maglev train on, the structure with the floating car of magnetic is simplified the advantage that vehicle weight alleviates and system effectiveness is high greatly.

The specific embodiment
Below in conjunction with accompanying drawing structure of the present invention is described in further detail.
Fig. 1 has expressed the longitudinal sectional drawing along track length direction, and the magnetic floating mechanism of integrated suspension guiding traction function is suspended by the stator that is installed in the long stator synchronous linear motor on the ground rail beam (100) and the normal conductive magnetism suction of mover (300) realization that is installed in the motor that is used as levitating electromagnet on the floating car of magnetic.Be without loss of generality, Fig. 2 and Fig. 3 can be considered the K-K section of Fig. 1, the iron core of the stator of long stator synchronous linear motor (120) and the upper symmetry of iron core (320) as the mover of the motor of levitating electromagnet are provided with many wide non-ferromagnetic longitudinal slots in opposite directions (as among the figure 101,102,103 and 301,302,303).Electric mover, air gap (200) consist of magnetic circuit with motor stator.By the electric current in control levitating electromagnet (being electric mover) excitation winding (310), can control the size of the electromagnetic attraction that levitating electromagnet produces, thereby realize that electromagnetic attraction suspends.Symmetrical three phase windings (110) are installed on the stator of motor, and the pole span of motor stator is identical with the pole span of electric mover (being levitating electromagnet), and (310) are an electromagnet excitation winding of electric mover among the figure.When passing through balanced three-phase current in the stator winding of motor, stator winding produces travelling-magnetic-field, and it and levitating electromagnet magnetic fields produce longitudinal traction power (its magnetic fields direction as shown by the arrows in Figure 2), and electric mover is longitudinally moved.By the control to long stator synchronous linear motor, can realize the full decoupled of tractive force and lift force, in other words two each other not impacts of power.In mechanism of the present invention, suspend and all realize by the long stator synchronous dynamo with traction function, this and often to lead high-speed magnetic floating similar.When mechanism's transverse shifting, the stator of long stator synchronous dynamo and the iron core of mover (groove center) line of centers also produce cross travel, the result has produced transverse magnetic flux automatically, thereby automatically produce electromagnetism (guiding) power that resets, force the stator of long stator synchronous dynamo to align with center unshakable in one's determination (groove center) line of mover, thereby guarantee that this mechanism is in correct position.This mechanism adopts the special construction of leaving many wide non-ferromagnetic longitudinal slots at the stator core of long stator motor and the iron core of mover electromagnet (being levitating electromagnet), the passive electromagnetism guide function of realization mechanism and needn't increase extra independent electromagnetism guiding mechanism.Under normal circumstances, the stator of long stator synchronous dynamo overlaps with the line of centers unshakable in one's determination (or groove center line) of mover, and the magnetic field between stator and mover only has vertical By component; When mechanism's transverse shifting, the stator of long stator synchronous dynamo and the iron core of mover (or groove) line of centers also produce cross travel, and Distribution of Magnetic Field as shown in Figure 3 between stator and mover.Magnetic field between stator and mover will have horizontal Bx and vertical two components of By at this moment.The direction of the electromagnetic force that the lateral component Bx of magnetic flux produces is reducing on the direction of cross travel, namely, it is (guiding) power that resets, under the effect of this power, this mechanism can force the stator of long stator synchronous dynamo to align with center unshakable in one's determination (groove center) line of mover automatically, thereby guarantees that this mechanism is in correct position.Under the condition of the By component in magnetic field between stator and mover constant (being that lift force is constant), cross travel is larger, and guidance force is larger, so mechanism can realize the failure-free guiding.
Among the present invention, guidance force is produced by the lateral component Bx in magnetic field between stator and mover, thereby all are by changing between stator and mover Magnetic Circuit Shape or additional permanent magnet when cross travel increases, the magnetic field lateral component increases to produce the method for larger guidance force automatically, its principle is identical with the present invention, all among of the present invention comprising, but not as the present invention simple and reliable.In addition.Wide non-ferromagnetic longitudinal slot of the present invention obviously comprises the wide non-ferromagnetic longitudinal slot space that consists of take air as weighting material, and when reality was implemented, other conventional nonferromagnetic material that wide non-ferromagnetic longitudinal slot is filled non-air was more effective practical.
Compare with present middle low-speed maglev train, the present invention's guiding traction function that will suspend integrates, and does not need special-purpose levitating electromagnet.Motor stator and inverter are installed in ground, and the structure of the floating car of magnetic is simplified greatly, and vehicle weight alleviates, and efficient improves.Compare with present high-speed maglev train, it does not have extra electromagnetism guidance system, and the equipment of vehicle reduces, from heavy and light, and system simplification.So having advantages of, this scheme often leads type high speed and middle low-speed maglev train at present.
