Definitions

  • the present invention describes a multi articulated vehicle for cargo and passengers transportation, in which said vehicle magnetically levitates over an adequate rail, and is composed of small modules, being able to perform sharp turns.
  • a superconductor material is characterized by presenting no electrical resistance and by the null magnetic field inside the material. This second condition, also known as the "Meissner effect", can be easily demonstrated by experiments where a permanent magnet levitates over the superconductor's surface. The magnetic field lines do not enter in the superconductor that behaves as if another identical magnet were inside the material. Therefore, the magnet suffers a repulsion that cancels its weight and "levitates" over the superconductor.
  • maglev Magnetically Levitating Transport System
  • Maglevs are a transportation system that hovers, guides and thrusts vehicles, mainly trains, by using electromagnetic forces. Due to the fact that they are not compatible with conventional railroad systems, Maglevs must be designed from scratch, including not only vehicle but also the tracks, which are specially designed for magnetic levitation and propulsion. In addition to that, route and inclination stabilization is necessary and translational or lateral movements can cause serious problems.
  • Maglev is stable.
  • a complex monitoring system must be present.
  • the present invention's objects are the manufacture, assembly and operation of devices, known from prior art, that allow the construction of trains based on the "Meissner effect" of High-Temperature Superconductors - HTS.
  • the present system comprises a standard base which preferably comprises cryostats filled with liquid nitrogen (-196 0 C), linear motor components, retractable wheels and space for optional accessories. Above this base a compartment for passengers and cargo is installed, connected by special rubber connectors, forming a multi articulated train - Maglev Cobra - allowing it to perform sharp turns, resembling a snake's movement.
  • a multi articulated vehicle based on magnetic levitation comprising: a) a base comprising: i) superconducting material; ii) means for cooling the superconducting material; iii) means for linear displacement b) a transport compartment for transporting cargo and/or passengers; and c) connecting means for connecting transportation compartments; wherein the weight of the compartment is distributed over the entire base. It is a further object of the invention a multi articulated vehicle based on magnetic levitation capable of performing sharp turns, suitable for urban areas.
  • Figure 1 shows the base responsible for levitation in perspective, wherein in (1) the transportation compartment for passenger and cargo is placed. It is also possible to see the cryostat (2), comprising blocks of superconductors cooled to liquid nitrogen temperature, the coils and other devices of the linear motor (3), mechanical system comprising the retractable wheels and braking means (4).
  • the whole base levitates over the magnetic field produced by the Neodymium-lron-Boron permanent magnets (5) installed inside the track (6) and protected by protections means (7) that also contains the power cable and is attached to the track's surface that comprises an induction plate (8), forming the secondary of the linear motor.

  • suitable superconducting materials are those classified as high-temperature superconductors - HTS 1 i.e. materials that have a superconducting transition temperature above 3OK.
  • Examples of such include, without limitation copper-oxide superconductors such as YBCO and BSCCO. Since the superconductive material only exhibits superconducting properties in low temperatures, such as -196 0 C, they need to be cooled down in order to attain said property. The most common means for cooling the superconducting material is to put it into liquid nitrogen.
  • Suitable means for linear displacement include, without limitation, linear motors, which are alternating current electric motor that has had its stator unrolled, thus producing a linear force along its length. Any conductor, be it a loop, a coil or simply a metal plate, that is placed in a magnetic field will have currents induced in it, creating opposing magnetic field, which repeal each other, forcing the conductor away from the stator, in the direction of the moving magnetic field.

  • the passengers compartment may also be a command module, comprising means for operating the train.
  • the length of the compartment can be smaller than conventional trains, thus allowing sharp turns to be made and being excellent for urban areas. It also enables the vehicle to climb up and down hills containing inclinations up to 15%, which is 3 times steeper that the conventional trains, that travels in inclinations of 4%.
  • the connectors of the present invention are connectors that allow the sharp turns to be performed correctly, and its shape allows a controlled deformation.
  • the rubber comprises spaces for this controlled deformation.
  • Suitable connectors are made of elastic material that can endure deformation, such as rubbers known in the state of the art. It also contains an internal steel structure, that acts as reinforcement for the connector.
  • the connector may be attached to the transportation compartment by any known means such as bolts, screws, adhesives.
  • the vehicle additionally comprises safety means, such as retractable wheels and brakes.
  • the retractable wheels are meant to be used only in the event of loss of superconductivity, such as the warming up of the superconducting material, ceasing the magnetic levitation.
  • the wheels will be used to avoid the contact of the cryostat and the permanent magnet. It is also present brakes for breaking both the linear motor and the retractable wheels.
  • the entire magnetic levitation system is monitored and controlled by several elements, able to gather, transmit and interpret the relevant information.
  • the monitoring system is mainly concerned with the correct functioning of the cryostat (cooling system) and braking system, and is monitored by electrical cables, sensors, softwares and suitable interfaces
