Definitions

  • the invention relates to a rollable model toy vehicle, such as a model railway vehicle or model automobile, which is movably guided on a ferromagnetic guide line, with at least one permanent magnet attached to its underside at a distance above the guide line.
  • a model vehicle of this type is described for example in DE-GM 1 806 055.
  • a permanent magnet is attached under a railway vehicle, which is intended to press the railway wagon onto its track to prevent it from derailing.
  • the permanent magnets used in the two model vehicles mentioned above to achieve the goals set there give the vehicles a clumsy and repulsive appearance for model railroad enthusiasts. They are therefore not suitable to improve the tipping and running stability or the frictional engagement of the drive wheels of a model vehicle without thereby not significantly changing its external appearance, which is supposed to come as close as possible to the original of large-scale technology.
  • the permanent magnet (s) are arranged in / on parts of vehicle-specific replicas arranged below the model toy vehicle, such as vehicle accessories and / or wheels and / or bogies or bogies, or form these replicas themselves.
  • a model toy vehicle constructed in this way not only sticks to its guideway in a stable manner, but also offers its drive wheels slip-free adhesion on the guideway, so that the model toy vehicle according to the invention can even overcome extreme inclines without problems.
  • rare earth cobalt magnets used as permanent magnets of which cobalt samarium magnets prove to be particularly advantageous.
  • the latter make it possible for the model vehicle to easily master line gradients of more than 100%.
  • the extremely high magnetic force that even tiny magnets made of this material can exert, for example, practically no slip between a rail and a drive wheel of a model locomotive equipped with cobalt samarium magnets.
  • a model locomotive provided with tiny magnets of this kind can even move upside down on a track while traveling.
  • cobalt samarium magnets allow them to be used in parts of the substructure of model vehicles, e.g. in oil coolers, on or in the bogies of or in equipment boxes under the Model D train wagons, in pressure vessels or the like, practically invisible to the outside viewer, whereby they have to be positioned just above the rail made of ferromagnetic material in order to be able to use them to be able to exercise full magnetic effect optimally.
  • the cobalt samarium magnets would be completely invisible if they were inserted into the respective mold by means of pressure or injection molding during the manufacture of the individual parts that form the substructure of model vehicles and cast in during the casting process. Any loss of field strength of the cobalt-samarium magnets during the brief temperature increases during casting can be compensated for by re-magnetizing the magnets after the castings have been removed from their mold.
  • model railroads have so far achieved the static friction required for the drive wheel / rail system by using additional weights made of metal arranged in the locomotive or in the railcar, when using cobalt samarium magnets, any superfluous weight in the drive or waive other railway wagons.
  • This has the advantage that now all body parts of model vehicles can be made from light, robust materials, in particular plastics.
  • the lightweight construction could lead to considerable cost reductions in the production of model vehicles.
  • the lifespan of a model vehicle produced in lightweight construction is likely to be longer compared to the model vehicles built to date in heavier quality, since the impact force is lower in the event of an unintentional fall on stone floor or the like.
  • the permanent magnets of high magnetic field strength used in accordance with the invention in particular the cobalt samarium magnets, in relation to the model vehicles that receive them, a sensible consideration and coordination between the desired goals, namely a good static friction between the drive wheel / rail system on the one hand and the demand for a not too high bearing load on the axle bearings of railcars and / or railroad cars on the other hand.
  • the conventional bearings of model vehicles may need to be strengthened, taking into account the increased bearing pressure generated by the body that carries the magnets and is thus attracted to the ferromagnetic guideway, which stresses the bearings.
  • the permanent magnets used according to the invention are not to be permanently attached to the model vehicles, they could also be attached to them or removed therefrom.
  • a model vehicle designed according to the invention could also be produced with wheels made of electrically non-conductive material, for example made of plastic, if the current is drawn from the control route via sliding contacts.
  • non-magnetic rail material for model railways such as brass, alpaca, plastic or the like
  • a rust-protected iron rail between the two rail tracks in the area of larger slopes or in narrow rail curves, in order to achieve the desired contact effect and can only be achieved in areas where the drive wheels are slipping or the model railroad is derailed.
  • the contact effect would hardly be necessary on a level and / or straight line, and may not even be desirable.
  • the rail tracks running on such a route, in particular of garden railways built outdoors are made of rustproof non-ferrous metals. This would cancel out the effect of permanent magnets attached under the model railway. This could have the consequence that the above-mentioned increased stress on the axle bearings of the model railroad in the area of the non-iron rail parts would be completely eliminated.
  • a model railroad car 1 placed on a guideway (here: railroad track) 7 has a substructure 3 with two bogies or bogies 4, each with two wheels 8.
  • a small permanent magnet 2 with a high field strength, as far as possible a rare earth magnet, such as a cobalt samarium magnet or the like, is either permanent or removable on both sides of the model railway wagon appropriate.
  • the permanent magnets 2 can also be designed as other parts of the substructure 3 of the model railway vehicle 1, for example as a pressure vessel 5 or as a device box 6.
  • the magnets can also be cast into these containers 5, 6 or in the chassis 4 when they are being produced and can therefore be hidden therein from the eye.
  • the line of force N, S of the magnets 2 is perpendicular to the guide line 7.
  • the permanent magnets could also be arranged in the oil coolers modeled between the bogies and thus invisible to the eye of the critical model railroad enthusiast, which is not shown here.
  • FIG. 2 shows a schematic illustration of a model gear train 19, the wheels of which, as usual, are mounted on a double rail 22, 23.
  • a rack 18 is arranged between the two rail tracks 22, 23, preferably on steep sections, and is fastened to the sleepers.
  • a pinion 20 belonging to a pinion 21 is arranged on the underside of the model gear train 19 and is in engagement with the rack 18 in the position of use.
  • the model gear train 19 is pulled onto the rail tracks 22, 23 by means of permanent magnets 24, which also ensures that the pinion 20 is always in engagement with the rack 18 remains, so that the dreaded rising of the tooth flanks and notching of the pinion 21 is prevented.
  • a disk-shaped, axially magnetized permanent magnet 25 could possibly also be provided in the pinion 20 itself, which would be optimal with regard to the achievable attraction force between pinion 20 and rack 18.
  • Fig. 3 branches a schematic representation of a railway axis 12 with two wheels 8 made of ferromagnetic material.
  • the two wheels 8 each have coaxial permanent magnets 9, 10 with the polarity N, S shown in FIG. 3 on the inside.
  • the two permanent magnets 9, 10 are connected to one another via the ferromagnetic axis 12.
  • the axis 12 could also consist of non-ferromagnetic material. Then it would have to be provided with a ferromanetic coating 14 to ensure the magnetic flux of force. If the axis should not be bare to the outside, but should have a non-ferromagnetic layer, it must have at least one ferromagnetic core (13).
  • the two wheels 8 are magnetized differently, the left one forms the north pole, the right one the south pole of the permanent magnet system.
  • FIG. 4 shows a railway axle 12 with two wheels 8, each of which has an annular groove 16 on its running surfaces 15, which are formed radially around a permanent magnet 11 embedded in the wheel 8.
  • This annular groove 16 could be open. Expediently, however, it should be filled with a non-ferromagnetic material 17, for example brass, so that the wheel 8 lies snugly on its rail 22, 23 and can roll off without problems.
  • the two permanent magnets 11 also ensure good wheel / rail adhesion.
