In an optional specific embodiment, the solution of the present invention, main function is to solve existing magnetic suspension train to exist The skills such as structure is complicated present in the suspension of deficiency and existing magnetic suspension train in safety and economy, guiding mechanism Art problem.So the solution of the present invention, by designing a kind of running mechanism and its track based on passive permanent magnetic suspension technology, Realize the driving and suspension movement of passive type magnetic suspension train;Meanwhile the running mechanism and track are suitable for vacuum pipe traffic System, and have the potentiality that the speed of service is further promoted in vacuum pipe.
Specifically, the running mechanism using low-floor type bogie+magnetic float module combination, and by linear motor into Row driving.It is travelled in orbit in low-speed stage by wheel, while magnetic floats module and interacts with aluminum alloy rail, magnetic The permanent magnet cutting magnetic line of floating module, to generate upward lift in orbit.After train reaches certain speed, with Floating is then realized in the increase of lift, and steps into stable cruising phase.When train braking, first by linear motor into Row eddy-current brake, with the reduction of the speed of service, magnetic floats module and is gradually reduced with lift caused by track, and train lands again Mechanical braking, and the final platform smoothly stopped AT STATION are realized onto track, then by wheel.L-shaped track is not only to walk Row mechanism provides upward lift, while side also provides guiding force, to guarantee that train always can be in track Safety traffic.
Such running mechanism and its track are particluarly suitable for using in vacuum pipe, below just to be run in vacuum pipe For, running mechanism and its track of the invention are specifically described:
The running mechanism may operate in closed tunnel 3.Railway roadbed 2 is covered in tunnel 3, in the road center position of railway roadbed 2 It sets, linear motor stator electric 1 is installed along tunnel direction of travel, be evenly arranged L shape track 4 in the two sides of linear motor stator electric 1. It is run on track 4 by the passive type magnetic suspension train 5 that low-floor bogie 6 and car body 7 form.
Optionally, low-floor bogie 6 mainly floats module 8, independent wheelset 9, linear motor rotor by the magnetic of semi-circular shape 10, framework 12, central connecting piece 14, drawing pull bar 16, linear electric machine traction frame 17, anti-snake damper 18, vertical damper 19, lateral damper 20 etc. forms.
Wherein, framework 12 is located at left and right sides of bogie, is designed using 100% low-floor type, is existed by central connecting piece 14 Centre is connected.Two groups of linear electric machine traction framves 17 are fixed in the rear and front end of two groups of frameworks 12 respectively.The front and back two of every group of framework 12 Two groups of independent wheelsets 9 are fixed in the lower section at end respectively.Independent wheelset 9 is solid rubber wheel+metal wheel shaft combining form, is risen The effect of support and low-speed stage operation.And magnetic floats the lower recess that module 8 is then mounted on framework 12, center and independent wheelset 9 Center it is conllinear.Two groups of drawing pull bars 16 are connected between linear electric machine traction frame 17 and central connecting piece 14, and four groups anti- Hunting Damper 18 is separately mounted to the outside of linear electric machine traction frame 17, symmetrical arrangement.Four groups vertical damper 19 Then it is separately mounted to the top of linear electric machine traction frame 17, symmetrical arrangement.During two groups of transverse dampers 20 are then mounted on Entreat the left and right sides of connector 14.
Two groups of low-floor bogies 6 are arranged in the rear and front end of passive type magnetic suspension train 5 along track direction of travel respectively, And it is run in track 4 always.Track 4 is made of L shape aluminium alloy extrusions, and bottom surface is arc-shaped, and the annular portion of module 8 is floated with magnetic Point parallel to each other, it is parallel that the vertical plane of module 8 is then floated in side with magnetic.
Specifically, the operational process of the running mechanism and its track is as follows:
Passive type magnetic suspension train 5 is supported on track by four groups of independent wheelsets 9 in the low-speed stage of stop phase and operation On 4, by linear motor rotor 10 and linear motor stator electric 1, driving is advanced jointly when starting.At this point, being made of Nd-Fe-B permanent magnet Magnetic float module 8 and carry out cutting magnetic line effect with track 4, generate upward lift, after reaching certain speed, passive type magnetic Aerotrain 5 realizes floating, and continues by linear motor driving to cruising speed.When braking, linear motor reversion, passive type magnetic Aerotrain 5 slows down, and with the reduction of speed, lift is gradually reduced, and passive type magnetic suspension arranges after being reduced to certain speed Vehicle 5 drops on track 4, and carries out mechanical braking until stopping by independent wheelset 9.From beginning to end, the L-type side of track 4 is all The vertical plane for floating module 8 with magnetic generates guiding force, it is ensured that passive type magnetic suspension train 5 is travelled along 4 center line of track always.And rail The arc-shaped bottom surface in road 4 also ensures certainly to neutrality, so that passive type magnetic suspension train 5 is also able to maintain in low-speed stage along track Center traveling.
Wherein, after vacuumizing in tunnel, the influence of the air drag as suffered by passive type magnetic suspension train 5 is substantially It reduces, it might even be possible to ignore, the speed of service will be also substantially improved, and can carry out high speed or ultrahigh speed operation, have Good speed-raising space.
From the above process as can be seen that due to using the support and low-speed stage of independent wheelset 9 as running mechanism Driving mechanism, therefore the sled mechanism relative to traditional routine conductive maglev train, have more excellent braking ability, safety It greatly improves.
Magnetic floats module 8 and forms upward lift using the anchor ring of bottom and the arc surface of track 4, and magnetic is utilized to float module The vertical plane of the vertical planes of 8 sides and track 4 forms guiding force, therefore magnetic is perfectly floated module and oriented module is integrated into Together.Relative to existing High Speed Maglev Vehicle ' and other several super high-speed rail sample car (magnetic based on maglpane principle Floating module and oriented module independently work), suspension+guide frame is more simple, is easier to engineering production.And relative to The circular arc magnetic of traditional magplane monoblock type floats module, and what the present invention used is respectively in the floating module of two groups of magnetic of running mechanism two sides Structure type, closer to the twin-engined layout patterns of airline carriers of passengers, from kinetically also more reasonable.
When passive type magnetic suspension train 5 low-speed stage run when, by independent wheelset 9 track 4 arc surface Traveling, since arc surface is from centering characteristic, passive type magnetic suspension train 5 ensures the guiding performance of low-speed stage.Work as passive type After magnetic suspension train 5 reaches certain speed floating, since magnetic floats the guiding of the side of module 8 and the vertical plane formation of track 4 Power equally can keep running along rail safety, phenomena such as derailing, topple will not occurs in the turning stage in high speed stage.
Relative to the train of other standards, the passive type magnetic suspension train 5 based on passive permanent magnetic suspension technology has more preferable Speed-raising space.It is particluarly suitable for operation in vacuum pipe.Common wheel track vehicle, even if being run in vacuum pipe, although It is restricted without air drag, but wheel track bring mechanical resistance is also to influence an important factor for it further raises speed.And surpass Magnetic conduction aerotrain, although also having good speed-raising space, the track as used in high-temperature superconductor magnetic-levitation train consumes permanent magnetism The dosage of body is excessive, and liquid helium technology of preparing needed for low-temperature superconducting magnetic-levitation train is again complicated, and economy is not so good as to be based on passively forever The passive type magnetic suspension train 5 of magnetic levitation technology.
Due to using low-floor type bogie, has shorter outer dimension than conventional bogie.If Operation in vacuum pipe influences due to not being related to air drag, then can further reduce required tunnel sectional dimension, thus Reduce the construction cost in tunnel.
In addition, it is necessary to explanation, the L shape formula of track 4, bottom surface are not limited to arc-shaped, it can also directly be horizontal base Face;Likewise, magnetic floats the form of annular rings of module 8, also become rectangle therewith.As long as i.e. L-shaped track 4 floats module 8 with magnetic Combining form be not limited to above-mentioned bottom surface form all by by protection of the invention.
To sum up, the solution of the present invention, at least can achieve it is following the utility model has the advantages that
