Definitions

  • the invention relates to a track specified in the preamble of claim 1 Genus and a kit and a method according to the preamble of claim 15 and 16, respectively for its production.
  • the driveways can be made with concrete or steel girders as well as supports on demand or to be built near the ground.
  • the girders in the direction of one before are arranged in series, all for the operation of the maglev train required equipment. This is especially true for the Guide the vehicles of a maglev required side guide rails as well for the reaction rails required for carrying and driving in the form of stator packets, their functional surfaces exactly on given by the routing space curves must lie.
  • the equipment consists of in particular the stator packs, of linear components running within Curved track sections the respective space curve in the manner of a polygon approach.
  • the resulting deviations from the ideal lines are extreme low, since the radii of curvature of the routes for reasons of vehicle construction is not may be less than about 350 m.
  • stator packs are a Magnetic levitation train with long-stator linear drive, usually also on its underside, alternately provided with teeth and grooves, in which a single- or multi-phase AC traveling wave winding is inserted (DE 196 20 221 A1), which is used to generate the for the drive of the maglev railway required traveling field is used. That's it customary to provide identical linear drives on both sides of the vehicles and therefore to equip each lane of a driveway with two parallel stators. This creates two separate but mechanically fixed drive systems.
  • Statorween same length is for design and cost reasons advantageous, but also brings disadvantages. These consist e.g. in that different sized column the ideal distribution of the magnetic field of the long stator to disturb. Since the individual stator packs are comparatively short (e.g., 1000 mm to 2000 mm), this leads to rapid periodic changes in the forces when driving over, with which the vehicles are kept in limbo, and as a result of it Parts of the track or vehicle may be excited to vibrate. These Vibrations can not only the life of all elements of the infrastructure and the Vehicles, but also the ride comfort and the sound generation unfavorably influence.
  • the off individual laminations of composite stator packs to prevent too rapid corrosion avoid having a corrosion protection layer of e.g. one to two millimeters too surround.
  • a corrosion protection layer e.g. one to two millimeters too surround.
  • the invention is therefore based on the object, the track and the kit of Initially designated genus in such a way that even with the use of Statorvolen with only a few different lengths periodic changes in load capacity When driving over largely avoided.
  • a cost-effective applicable method for the production of driveways resulting in Use of the same stator packs and fewer mass carriers, in particular for the production of driveways with two or more lanes, without an undesirably large Offset between the lanes occurs or other disturbances arise.
  • the invention is based on the recognition that large stator gaps and those of them outgoing impairments thereby largely avoid that the track not only composed of a small number of stator types of different lengths but this stator also in each stator so with each other be combined that result in the most favorable material gap widths. This can be done without or with a very small change in the grid of the stator slot to reach. This results in the further advantage that the carrier to be used unified and can be divided into a few types. Despite minor Cost increases for the production of different types of stator brings this significant Advantages with regard to the routing and configuration of different infrastructure configurations as well as the logistics required to build a roadway.
  • Fig. 1 shows a steel or concrete existing carrier 1, for the establishment of a Travel path according to the invention for a magnetic levitation railway with at least two parallel stators having long stator linear drive is suitable.
  • a carrier 1 which curves along a predetermined route is as indicated by a space curve 2 shown in its center plane.
  • schematically is a Cartesian coordinate system with mutually perpendicular Axles 3, 4 and 5 indicated.
  • the carrier 1 and the stators can move around all three axes 3, 4 and 5 are curved, with a curvature about the axis 3 of a cornering, a Curvature about the axis 4 a transition into a mountain or descent and a Curvature around the axis 5 corresponds to an inclination in the sense of a curve elevation.
  • stator 6th and 7 On the underside of the carrier 1 and on both sides of the space curve 2 is ever a stator 6th and 7, wherein in the embodiment, the stator 6 on the outside a running around the axis 3 arc, the stator section 7, however, on the Inside of this bow lies.
  • the stator sections 6 and 7 are along space curves 8 and 9 arranged, e.g. have the space curve 2 of the carrier 1 as a common center line. It should be understood that this is intended to be exemplary only, d. H. the positions of the space curves 2, 8 and 9 can also be defined in other ways. Alternatively, it would be z. B. possible to arrange the space curves 2, 8 and 9 in a plane to be produced in the Air gap between the long stator and the supporting magnet of the vehicle is located.
  • the Stator sections 6 and 7 each consist of a plurality of stator packets, which in Direction of the space curves 8 and 9 in succession and in the manner of a polygon are arranged. Their attachment to the carrier 1 can according to various known per se Procedure done. In addition, there is the whole, not shown in the drawing Track of a variety of in the direction of the space curve 2 arranged one behind the other Straps 1, which are straight or curved depending on the characteristics of the route could be. Finally, the carrier 1 in a conventional manner in a middle Part by means of a fixed bearing and at the two ends by means of one movable bearing Supports or other substructure stored and thus in two fields assigned. Even others, just one field or more than two fields and differently arranged Fixed and floating bearings may be provided.
  • Carrier of the type described, their storage, the attachment of the stator to the Carriers and the mounting of e.g. three-phase AC winding in the grooves of Stator sections 6 and 7 are generally known (DE 33 23 696 C2, DE 34 04 061 C1, DE 39 28 277 C1, DE 39 28 278 C2) and therefore need not be explained in more detail become.
  • FIG. 2 shows a plan view of the carrier 1 according to FIG. 1.
  • the projections of the space curves 2, 8 and 9 are then circles in the exemplary embodiment, but can also arbitrary other curves such.
  • Fig. 2 shows that the carrier 1 has an imaginary, indicated by a line 10 center plane and between two imagined, indicated by dash-dotted lines levels 11 and 12, the normal or perpendicular to the space curves 2, 8 and 9 are arranged.
  • This allows the Axles of the fixed and floating bearings of the carrier, not shown, also normal to the Space curves 2, 8 and 9 are arranged, and the same can for a carrier start 1a and a carrier end 1b apply.
  • Such an arrangement is especially for the production of driveways with two lanes (eg back and forth lanes) with two stators each appropriate.
  • stator sections 6 and 7 are made in the embodiment six straight stator packets 6a to 6f and 7a to 7f.
  • Each of these stator packages has the From Fig. 3 apparent, shown for the stator 6c, general shape and contains its bottom alternating teeth 14 and grooves 15 of equal length, one on the Curve 2 related, preselected pitch or a preselected tooth / groove pitch 16 have.
  • Ended teeth 17 are usually only half the width of the other teeth 14, so that the end teeth 17 of two adjacent Stator packages together each have a tooth of the length of a tooth 14th form.
  • the carriers 1 are independent of whether they are straight or curved are each between two lying in the planes 11, 12 points 18 and 19 ( Figure 2) the space curve 2 arranged whose distances an integer multiple of the Tooth / groove pitch 16 correspond.
  • the carrier 1 in the path direction (space curve 2) to a degree shorter, which allows between the carrier beginnings 1a and 1b ends and the associated imaginary planes 11 and 12 each leave a gap 20, 21, the together with a corresponding gap 21 or 20 of an adjacent carrier one Forms an expansion gap.
  • the space curve portions between the planes 11 and 12 have different Lengths, i. the distance of the planes 11, 12 is, along the space curve. 8 measured, longer than the distance measured for the space curve 9. Therefore, if the stator packs all had the same material overall length, would be between stator 6a to 6f of the stator 6 formed column 23 inevitably greater than gaps formed between stator packets 7a to 7f of the stator section 7, which especially at smaller radii of curvature to the excitation of the above-mentioned Vibrations due to unequal load forces when driving over the column 23, 24 lead can.
  • stator end packages 6a, 6f, 7a, 7f of the inner and outer stator sections 6 and 7 lying central stator three types namely to provide "first", “second” and “third” stator packs.
  • All Stator packages are straight.
  • the "first” stator packs have an average length. there is the length of the "first” stator packets chosen so that the distance between the points 18, 19 without rest is divisible by them, or vice versa, the distance between the Points 18, 19 so that it is an integer multiple of both the tooth / groove pitch 16 as well as the length of the "first” stator packs.

  • the "first" stator packs e.g., 6c in FIGS. 2 and 3
  • eleven teeth 14 and two end teeth 17 have a total length of 1032 mm.
  • Shall like in the embodiment six such stator packs are mounted per carrier 1, the distance between Points 18 and 19 are six times larger, d. H. according to a system distance of 6192 mm, which corresponds to 72 times the tooth / groove pitch 16. This System spacing is repeated in the path direction of how the carrier 1 is used becomes.
  • the carrier 1 along a space curve 2 with a radius of 350 m is curved about the axis 3 and a bank about the axis 5 of twelve Degree has, while the pitch is fixed about the axis 4 with 0 °.

These opposite the "first" stator packs with 1032 mm extended stator 6b, 6d and 6e are hereinafter referred to as "second" Statorpakte designates.
  • This small oversize is insignificant because at the joint between two carriers 1 according to a particularly preferred embodiment of the Invention Statorendbrie 6a, 6f and 7a, 7f are arranged, which have a length of only 1024 mm instead of 1032 mm.

  • G is thus a measure of a total material gap width, which is to be taken into account within a stator section in addition to the mounting gaps and the gaps resulting from the coating.
  • Another option is to change the length of the To distribute the end teeth alone on the existing teeth, which is a justifiable Length change of the teeth of 0.25 mm correspond and would have the advantage that the width of the grooves 15 remains unchanged, as is the case for a safe installation of the AC cable is desired.
