US 7533616 B2Abstract
A guiding magnet system for a magnetic levitation vehicle is described. The guiding magnet system has a plurality of magnet arrangements (50, 51, 57) which each comprise a core (33) extending in the vehicle's longitudinal direction and have at least two winding levels (planes). In each winding plane an even number of windings (58, 60 or 59, 62) is provided. At one end of the magnet arrangements (50, 51, 57) two windings (e.g. 58 a, 58 b) each lying one behind the other but diagonally above each other and being connected in series, form a pair of windings linked to an assigned control circuit. At the other end of said magnet arrangement either also two such winding pairs or single winding pairs are provided which comprise two windings (60 a, 60 b or 61 a, 61 b) arranged one behind the other. Further, a magnetic levitation vehicle equipped with such a guiding magnet system is described (FIG. 10).
The invention bears the advantage that every magnetic arrangement and, therefore, every guiding magnet can be configured as an intrinsically redundant unit, if required. This means that on failure of any winding of any guiding magnet or of any control circuit assigned thereto, there is no need for a neighboring magnet to take charge of the guiding function of a defective winding. As an alternative, however, it is also possible to involve adjacent magnets as done hitherto to ensure redundancy, while reducing the total weight of each guiding magnet system substantially and configuring the arrangement in a way that rolling moments cannot occur. Furthermore, a magnetic levitation vehicle can be provided in which —despite a substantial reduction in weight of the magnet arrangement as compared with the prior art construction —ensures that additional load changes which would have to be taken-up by the guideway will not occur during operation of the magnetic levitation vehicle.
As shown on FIG. 2, the carrying magnet 5 and the guiding magnet 9 each form a module affixed to the support brackets 6, and each comprise a magnet arrangement 10 or 10 a , respectively, for the functions of “carrying” and “guiding”. However, it is obvious that a plurality of such modules can be mounted at the magnetic levitation vehicle 1 in lateral arrangement side by side and one behind the other as viewed in the direction of travel.
The magnet arrangement 10 for the “carrying” function is comprised of magnet poles 11 arranged one behind the other, whose windings 12 and cores 14 being schematically indicated in FIG. 2 for one of said magnet poles 11 are electrically connected in series and usually surrounded by a corrosion protection in form of a cast resin layer or the like. Said cores 14 of the individual magnet poles 11 are connected to each other by pole backs not shown and affixed by pole plates and rods penetrating through these pole plates, also not shown, to a magnet back box 15 of the magnet arrangement 10. Engaging to this magnet back box 15 via primary springs are the support brackets 6 (FIG. 1) which are connected with a bend-proof understructure or suspension frame 16 being comprised of longitudinal and transverse connectors and supporting a car body 17 of said magnetic levitation vehicle 1 (FIG. 1) being equipped with a passenger cell.
If implemented in practice, the arrangement shown on FIG. 8 is roughly obtained for the embodiment of FIG. 7. The travelling direction of the magnetic levitation vehicle 1 is designated by an arrow v, its nose or front end with the reference numeral 40. Furthermore, some suspension frame sections 41, 41 a, 41 b of the suspension frame 16 (FIG. 1) are shown in a roughly schematic view, arranged one behind the other in the longitudinal direction of vehicle 1 and coupled via pneumatic springs not shown, to the car body 17 of the magnetic levitation vehicle 1. In their longitudinal direction, the suspension frame sections 41, 41 a, 41 b have supporting elements 44, 45 in form of frame parts that are arranged at a certain distance to each other and connected by longitudinal girders 43, and that are provided with a front-end and a rear-end supporting part 46, 47 or 48, 49 each. In the embodiment, the guiding magnet FM1 being on the front in travelling direction is so connected to the suspension frame section 41 that its front end is connected to the rear supporting part 47 of the front supporting element 44, while its rear end is connected to the front supporting part 48 of the rear supporting element 45 in hinged arrangement, as is clearly shown on FIG. 8. The next guiding magnet FM2 is usually connected at its front end to the rear supporting part 49 of the rear supporting element 45 of the suspension frame section 41, and at its rear end it is connected to the front supporting part 46 a of the front supporting element 41 a of the suspension frame section 41 a following next in travelling direction. The arrangement as described hereinabove can be continued along the whole magnetic levitation vehicle 1 from the nose to the tail. However, preference is given to installing a braking magnet 50 after the third guiding magnet FM3 along a section which corresponds to the length of a guiding magnet, said braking magnet forming a zone being free from any guiding magnet and, for example, being part of an eddy-current brake which also cooperates with the guiding rail 8. Thus, at this location the engagement e.g. of guiding magnet FM3 at the rear supporting part 49 a of supporting element 45 a is missing in the same way as the front end supporting part 46 of the front supporting element 44 in the nose area 40 is not coupled to a guiding magnet, because the guiding magnet FM1—viewed in the direction of travel—is also succeeded by a zone free from a guiding magnet. The arrangement is similar on the right side as shown in FIG. 8, i.e. on the side lying behind the braking magnet 50 in the direction of travel. Moreover it is obvious that in FIG. 8 only one side, i.e. the left side of the magnetic levitation vehicle 1 in the direction of travel is shown and that on the right side which is not visible in FIG. 8 there are corresponding guiding magnets and other braking magnets, if any.
FIGS. 11 and 12 finally show an embodiment of the invention considered best at present. Here it has been considered that transitional areas 65 between two sections 66, 67 of a magnetic levitation vehicle 1 coupled to each other and running one behind the other also form zones that are free from guiding magnets and which lead to critical load changes. For redundancy considerations, these transitional areas 65, when applying the embodiments of FIGS. 7 and 10, are usually treated as magnet-free zones in the same way as those areas bordering the nose area 40 or a braking magnet 50, respectively, i.e. two diagonally connected pairs of windings each (e.g. 58 or 59 in FIG. 10) are provided for there. Contrary, in the embodiment of FIG. 11 and FIG. 12 it is proposed to provide a guiding magnet FM5 having a magnet arrangement 68 in every transitional area 65, said magnet arrangement 68 having four windings 69 to 72 lying one behind the other as in the magnet arrangement 51 (FIG. 10). Accordingly, two windings each, e.g. 69 and 70, are arranged at the rear end of the one section 66 and the other two windings, e.g. 71 and 72, at the front end of the next section 67 and, for example, all of them are arranged in the same winding plane. Moreover, a guiding magnet FM6 bordering the rear end of the forerunning section 66 and one guiding magnet FM7 bordering the front end of the trailing section 67 is provided with magnet arrangements 73 and 74, respectively, which are also merely composed of four windings lying one behind the other and preferably arranged in the same winding plane, connected in pairs according to FIG. 11, and linked to assigned control circuits. Thus, it is achieved—without enhancing the weight as compared with FIG. 9 and FIG. 10—that there is a continuous, uninterrupted band of windings or a continuous magnetic flow band between two hitherto magnet-free zones. In this band, the windings are located individually one behind the other, with the consequence that a constant break-off and new build-up of the magnetic flow is avoided and that load changes and moments to be considered can occur only where magnet-free zones are unavoidable as at the beginning or end of a magnetic levitation vehicle or at the braking magnets. It is further clear that the arrangement described in FIGS. 9 and 10 for the nose area 40 can also be provided in the tail area, particularly so if the magnetic levitation vehicle 1 is configured symmetrically to the vehicle centre and for movement in two opposite directions. Moreover, it is advantageous that nearly all supporting parts of the suspension frame sections 41, 41 a etc. are connected to a magnet arrangement each.
