Definitions

  • magnetizable carriers suspended from under each side of a railroad car support lift and traction magnets and side-to-side guide magnets which are electrically controlled to move along the underside and upright of an inverseT shaped magnetizable rail mounted from the tops of stationary C-shaped rail supports.
  • stationary lift magnets engage the carrier and guide the car along the desired direction.
  • Interlaced non-touching fingers magnetically couple the carriers from one car to the other.
  • carrying magnets are generally mounted above the railway cars in order to keep them floating without other devices to be attached to the vehicle itself.
  • head masts carrying supports for the rail-like armatures that serve as magnetic keepers or short circuits are required.
  • Another object of this invention is to improve suspension railways. Another object of the invention is to improve railways where cars are supported against the force of gravity above a rail arrangement by means of carrying magnets disposed below the cars.
  • Another object of the invention is to eliminate the beforementioned disadvantages.
  • the guide magnets are also mounted on the carrier.
  • the rail means includes a magnetizable structure forming an armature for both the carrying magnet and the guide magnet.
  • one carrier mounted on one side of the vehicle supports one carrying magnet so that it is magnetically coupled with one rail of the rail means and another carrier supports another carrying magnet so that it is coupled with another rail of said rail means.
  • the rails are interrupted at switch areas where the rail means diverge or converge, and slide rails for mechanically supporting the car are disposed in the switch area.
  • the slide rails are disposed so thatthe carrying magnets slide on the slide rails.
  • the slide rails are equipped with a slide coating.
  • stationary carrying magnets are disposed in the switch area and the carriers include auxiliary armatures for coupling magnetically to the stationarycarrying magnets.
  • the stationary carrying magnets are controlled so as to be energized along the travel direction in which the vehicle is to pass.
  • the guide magnets are energized in accordance with the direction of travel as a switch is passed, and thereby assume control of the vehicle.
  • the carrying magnets are disposed to jut out latterally and under the rail.
  • the rails are preferably supported on C- shaped carriers.
  • the distance between the sliding surfaces of the rail means and the carriers is less than the distance between the carriers and the bottom of the cars. In this manner the bottoms of the cars are protected from frictional engagement with the rail means in the absence of magnetic lifting forces.
  • one railroad car following another is magnetically coupled to the other by means of magnetic extensions having non-touching interlacing fingers.
  • FIG. 1 is a sectional drawing ofa part of a system embodying features of the invention, and showing in detail the essential parts of one side of the vehicle and the accompanying rail arrangement as the vehicle enters the switch area at the section 1-] of FIG. 2;
  • FIG. 2 is a top view of the rail arrangement in the switch area where a vehicle is about to be switched;
  • FIG. 3 illustrates a top view of a rail arrangement in a switch area at the end of a diverging pair of rails
  • FIG. 4 is a section at IIII of FIG. 3 of the system in FIG. 1, again showing the bottom of one side of the vehicle coupled to one rail as it comes out of the switching area;
  • FIG. 5 is a sectional view illustrating the vehicle of FIG. 1 as it comes-out of the switching area at the section III-III of FIG. 3;
  • FIG. 6 is a top view of two railroad cars forming a part of the system embodying features of the invention and the means for magnetically coupling the car in the system embodying featuresof this invention;
  • FIG. 7 is a side elevation of the structure in FIG. 6.
  • a carrying magnet 1 projects from a carrier 2 at the bottom 5 of an otherwise not disclosed vehicle. The latter is driven by a known linear motor arrangement, also not shown.
  • Another carrier 2 which is an identical mirror image of the carrier shown is located on the other side of the vehicle.
  • the carrying magnet 1 which juts out laterally from the carrier 2 includes a pole plate 12 having electric windings 26 embedded therein. The magnet 1 extends over the entire length of the vehicle. It may be divided into various magnet sections if necessary or desired.
  • a rail 7 Spaced above the magnet 1, across an air gap 27, a rail 7 serves as an armature for the carrying magnet l.
  • a rail carrier 19 located on a rail bed 35 supports the rail 4.
  • the rail carrier 19 is C-shaped and composed of a foot 9, a center portion 20, and a head 24.
  • the unevenness or the deflections or other disturbances can be equalized.
  • the moving parts of the vehicle can be prevented from striking the fixed rail arrangement.
  • Known control and regulating equipment such as that used for many other control and regulating applications, are used for this purpose.
  • the asymmetries may become so great that the control and regulating process could be insufficient to prevent the moving parts of the vehicle from striking the fixed rail arrangement.
  • the rail carrier 19 which supports the rail along its entire line at regular intervals, such as every 2 meters, supports running surfaces 29 and 30 in the foot 9 and the center portion 20.
  • the corresponding parts of the vehicle, namely the magnet 1 can glide on the running surfaces 29 and 30 under these circumstances. If necessary the surfaces 29 and 30 can bring the vehicle to a standstill by converting the vehicles kinetic energy into frictional heat.
  • FIGS. 2 and 3 illustrate the manner in which the vehicle of FIG. 1 switches over from the rails of one track to a side track or from a through rail to a tongue rail.
  • an open section forms a gap 18 between a through rail 16 and a tongue 17.
  • the gap 18 must be sufficiently wide so as not to interfere with the beforementioned lateral motions emanating from the vehicle so that the carriers 2 and their associated parts 1, 6 and 23 can travel through.
  • a similar gap 31 is located on the side of the tongue rail opposite the gap 18. The gap 31 permits free passage of the corresponding parts when the vehicle is to travel on the curved track 32.
  • the magnetic circuit is interrupted by a very wide longitudinal air space when the carrying magnet 1 travels across the gap 18. This makes it impossible for the vehicle to continue floating magnetically.
  • the vehicle thus touches down on the running surfaces 29 of the feet 9 and slides along them. The sliding continues until the magnet is again cooperating with the corresponding portion of the rail 4 as it runs on the tongue 33 during straightaway travel or on the tongue 17 during travel around a bend.
  • This process of passing a switch can be improved by a through slide rail 21 attached to the feet 9 of the rail carriers 19.
  • the spacings between the rail carriers 19 are shorter in the area of the switch and particularly at the location of the slide rail 21 than along the remaining portions of the line. This makes it possible more readily to absorb the great mechanical stresses which occur here more frequently.
  • the slide rail 21 assures a more shock-free gliding action than the running surfaces 29.
  • the sliding surfaces are lubricated in the more conventional manner.
  • Such an arrangement is roughly comparable to the path of the flange of the usual flange wheel used in conventional railroads over a filler piece or fairing at the switch point in crossings and switches for the purpose of shock attenuation.
  • Such an arrangement is simple but not free of wear. In the suspension railway described above this would be the only place during operation of the vehicle that the vehicle does not glide forward while it is being floated magnetically.
  • a stationary carrying magnet 22 of appropriate length is fastened along the line in the switch area.
  • a cooperating auxiliary iron armature 23 is attached to the vehicle.
  • the coil of the stationary magnet 22 is electrically energized either continually or only when a vehicle approaches. In any event the vehicle is kept floating in the switch areas where the through rail 4 is interrupted. This is done by the the carrying magnet 22 and the auxiliary armature 23. This avoids the vehicles running over the surfaces 29 or the slide rail 21.
  • the slide rails 21 are also provided with the auxiliary armature 23 to take care of emergencies such as failure of the magnetic energization.
  • the vehicle may be guided through the switches either solely or only partly by the guide magnet 6 following through longitudinal rib 7 to the left for straightforward travel and to the right for a right turn.
  • the direction is selected by increasing or decreasing the energization of the guide magnet 6 located on the left or on the right below the vehicle bottom 5. This means it is controlled from the train. This contrasts with the control heretofore practiced with switch mechanism located off the train on the ground.
  • the guidance of the vehicle may even be programmed into the vehicle. This programming may cause the vehicle to turn off the through track on the basis of so-called target departure. On the other hand it may be said to respond to an emergency in the vehicle as a so-called emergency departure.
  • FIGS. 1, 4 and 5 The passage of a vehicle through a switch area may be followed by studying FIGS. 1, 4 and 5 successively.
  • the stationary carrying magnet or lifting magnet 22 operates together with the carrying magnet 1.
  • the carrying magnet 22 assumes the responsibility for keeping the left side of the vehicle floating to the extent that the carrying magnet I is unable to or is not adequately able to be held in suspension by the parts of the rail 4 which serve as the armature for the magnet 1.
  • the vehicle In the position shown in FIG. 4, that is in the section llII FIG. 3, the vehicle is already in the process of leaving the switch area. On the left side it is carried only by a rail portion 36. A rail portion 37 which is provided for straightforward travel remains out of action.
  • FIG. 4 A rail portion 37 which is provided for straightforward travel remains out of action.
  • a rail portion 38 now carries the vehicle while a rail portion 39, provided for'straightforward travel, remains out of action.
  • the effect emanating from the fixed carrying magnet 40 also ends at this position.
  • the other fixed carrying magnet would have been functional only during straight away travel.
  • the arrangement according to the invention obviates the switch setting time which would otherwise be required. Under these circumstances two vehicles traveling immediately behind one another can be separated. This can be done even if they have traveled up to the switch as a unit.
  • the system according to the invention does not require moving parts. Thus it is basically no longer necessary to limit the arc radius of the switch. As a result the switch can be traversed at full traveling speed. This enables a train leaving the line to slow down after it has passed the switch. Thus a train leaving a line need not interfere with the flow of traffic in the line.
  • the through-carrying magnets are provided with interruptions as shown in FIG. 6. These interruptions are distributed over the length of the train at the ends of the vehicles 10. The vehicles are shown only in part to the left of a pivot point 34. The purposes of the interruptions is to allow the train to negotiate curves.
  • teeth 14 are rounded off as shown in FIG. 7.
  • the teeth assure a virtually closed magnetic path even when the train negotiates curves and when the vehicles 10 are mutually pivoted about the pivot point 34. This results in a constant magnetic field. Therefore, the vehicles are floated in a quite and steady manner.
  • electrical control circuits are mounted on the vehicle or car, or cars 10 of FIGS. 1, 4, 5, and 6 for controlling the magnets l and 6. Similar control circuits for the magnets 22, and 41 are mounted according to one embodiment of the invention, on the cars or vehicles. According to another em bodiment of the invention the controls for magnets 22, 40 and 41 are mounted off the vehicle. Where vehicle mounted, these controls may be coupled from the train to a stationary energizing source.
