Definitions

  • the invention relates to a track carrier of the type specified in the preamble of claim 1 and a magnetic levitation train thus produced.
  • the trajectories of magnetic levitation trains are composed of guideways, which in addition to the specific for driving the vehicles, often designed as a stator packs of long-stator linear motors drive means and intended for tracking side guide rails also so-called sliding surfaces have, for example EP-B1-0 381 136 , These are usually mounted on the upper surface of the guideway support and serve both during normal stopping and in emergencies to settle the vehicles by means of attached to their underside skids.
  • the designations "sliding" surface and “sliding" blade are intended to express that the skids can be discontinued not only at a standstill, but also while driving the vehicles on the sliding surfaces and then be moved on this sliding until the Vehicle comes to a halt.
  • Such a situation may occur, for example, in the event of failure of a support magnet, because then an associated portion of the vehicle or its floating frame so far drops that the vehicle touches with at least one skid on the sliding surface.
  • an associated portion of the vehicle or its floating frame so far drops that the vehicle touches with at least one skid on the sliding surface.
  • the magnetic levitation vehicles high speeds of 400 km / h and induces more considerable frictional energies, and as a result, high temperatures and intensive wear occur in the area of the affected sliding partners.
  • the invention is therefore based on the technical problem of designing the sliding surfaces of the initially-mentioned guideway carrier so that not only the sliding properties of the sliding pair sliding surface / skid improved, but also wear and thus low-maintenance coatings are obtained.
  • the sliding surfaces according to the invention are provided with a matched to the Gleitkuferumaterial coating of ceramic material or ceramic hard materials, the sliding properties can be optimized so that a magnetic levitation vehicle od failure of a supporting magnet. Like still a relatively long distance can cover, without resulting in a critical for the infrastructure and / or the vehicle situation. The resulting increase in the distances between the planned along the guideway workshops reduces the investment and operating costs considerably.
  • the extremely low wear of the sliding surfaces in an emergency deposition or when driving with maintenance and assembly vehicles also brings the advantage of significantly increased maintenance intervals with it.
  • Fig. 1 schematically shows a cross section through a magnetic levitation railway with a drive in the form of a long stator linear motor.
  • the maglev train includes a plurality of guideways 1, which are arranged one behind the other in the direction of a predetermined route and on the undersides of track plates 2 arranged, provided with windings stator 3 carry packages.
  • vehicles 4 can run with support magnets 5, which are opposite to the undersides of the stator 2 and at the same time provide the exciter field for the long-stator linear motor.
  • the z. B. as the surfaces of special, attached to the track plates 2 Gleitancen 7 are formed.
  • the sliding surfaces 6 cooperate with attached to the undersides of the vehicles 4 skids 8, which are at a standstill of the vehicles 4 are supported on the sliding surfaces 6, so that between the stator 3 and the supporting magnet 5 comparatively large gaps 9 are present.
  • the supporting magnets 5 are activated to lift the skids 8 of the sliding surfaces 6 and in the suspended state produced thereby the size of the gap 9 on z. B. 10 mm. Thereafter, the vehicle 4 is set in motion.
  • Magnetic levitation railways of this type are generally known to the person skilled in the art (eg " New traffic technologies ", Henschel Magnetic Technology 6/86 ).
  • a roadway carrier 11 made of concrete is indicated, which is provided on its upper side with an elevation or strip 12 produced in one piece with it, which on its upper side has a sliding surface 14 for the skids 8 of the magnetic levitation vehicle 4 Fig. 1 having.
  • Such concrete track carrier 11 are z. B. from the Pamphlets ZEV Glas.Ann 105, 1989, pp. 205-215 or " Maglev Transrapid, the New Dimension of Traveling ", Hestra Verlag Darmstadt 1989, p. 21 - 23 which are hereby incorporated by reference to them as subject of the present disclosure.
  • the sliding surfaces 14 are provided according to the invention with a coating containing two superimposed layers 15 and 17.
  • the inner layer 15 is applied directly to the sliding surface 14, while the layer 17 is formed as an outer layer, so that the track support 11 after Fig. 2 actually the upper surface of the outer layer 17 should be referred to as the sliding surface, as normally only with the skids 8 after Fig. 1 comes into contact.
  • Fig. 2 further provided to produce the coating at least in an outer region of a friction and low-wear, to be matched to the material of the skids 8 ceramic material.
  • This ceramic material is particularly advantageously made of an oxide ceramic, in particular a mixture of aluminum oxide (Al 2 O 3 ) and titanium dioxide (TiO 2 ).
  • both layers 15 and 17 contain an oxide ceramic material.
  • the inner layer 15 which is applied to the existing concrete sliding surface 14 of the guideway carrier 1, expedient of a tough and ductile material to achieve good adhesion to the concrete and possibly compensate for different thermal expansion of the individual components at least partially.
  • the first layer 15 predominantly or even a mixture of 50 to 70 percent by weight of alumina and the balance 50 to 30 percent by mass of titanium dioxide, while the outer layer 17 z. B. contains at least about 90 percent by weight of alumina and the balance up to 10 percent by mass of titanium dioxide.
  • Fig. 3 it is a track in composite construction, which contains a plurality of successively arranged, made of concrete guideways 18, in the upper surfaces made of steel, provided with sliding surfaces 19 slide strips 20 are inserted (eg. EP-B1-0 381 136 ).
  • the sliding surfaces 19 are in the embodiment slightly above the surface of the rest of the guideway carrier 18 and can be provided in a conventional manner with a corrosion protection layer.
  • the coating contains an internal, analogous to the layer 15 after Fig. 2 trained situation 22.
  • the additive which in the embodiment of the Fig. 3 z. B. is a polymeric polyurethane resin, in a proportion of z. B. 20 to 40 percent by weight graphite is added as a lubricant, applied in the form of an outer layer 23.
  • the fact that the Surface of the ceramic material layer 22 has a comparatively large roughness, especially when applied by a thermal spraying method, as in Fig. 3 is schematically indicated by roughness peaks 24 and Rauheitstäler 25. This could lead to the final sliding properties being obtained only after a certain break-in period and after the grinding of the roughness peaks 24, which is undesirable.
  • the polymeric polyurethane resin with graphite as incorporated lubricant or lubricant here serves the purpose of adding the roughness valleys 25 of the layer 22 with a tribologically active material or to fill and seal. This ensures that the desired improved friction and wear behavior is obtained immediately after the application of the coating.
  • the coating shows a pronounced running-in behavior, ie, a stationary state with a low coefficient of friction is obtained only after a smoothing of the roughness peaks 24 of the layer 22 obtained by wear.
  • a particular advantage of the embodiment according to Fig. 3 There is also the fact that the inner layer 22 immediately after a degradation due to wear of the outer layer 23 in terms of the desired wear properties is fully functional.
  • the resin system used as additive is preferably a conventional, provided at the manufacturer with a tribologically active component system which is like the layer 22 of ceramic material applied by a spray or rolling process on the sliding surface 19.
  • the ceramic material is preferably applied to the sliding surfaces 14, 19 by a thermal spraying method. Suitable for this purpose are z.
  • a thermal spraying method Suitable for this purpose are z.
  • spray additives are used in the form of powders or wires.
  • layer materials for the existing of ceramic material or at least predominantly containing layers 15, 17 and 22 are preferably used aluminum oxide and titanium dioxide of various compositions.
  • ceramic materials metallic and non-metallic resin materials and mixtures of these materials with metallic constituents or plastics, which are generally referred to as "ceramic materials" in the context of the present application.
  • these tribologically optimized materials can be applied to all types of guideways because they adhere well to concrete, steel or hybrid structures.
  • a roadway carrier made of concrete Fig. 2 is pretreated with a sandblasting process. Subsequently, the sliding surface is coated with a non-metallic hard material layer of a mixture of Al 2 O 3 and TiO 2 .
  • the overall layer consists of two individual layers 15 and 17 applied separately in succession.
  • the inner, concrete-facing layer 15 consists of 60% Al 2 O 3 and 40% TiO 2 . It has a thickness of 0.3 mm and is comparatively tough and ductile.
  • the outer layer 17, which is characterized by very good wear properties, is also 0.3 mm thick and consists of 97% Al 2 O 3 and 3% TiO 2 .
  • the coating process used is flame spraying.
  • the finished coating has a thickness of about 0.6 mm and excellent sliding properties with very little wear, especially when using skids 8 from the above, with carbon fibers reinforce ceramic materials based on C-CSiC.
  • the surface of a hybrid guideway carrier after Fig. 3 made of concrete and steel is pretreated with a grinding process.
  • a graded structure of the coating is realized.
