Definitions

  • the object of the present invention is to produce rail vehicles, in particular urban vehicles, the floor of which is substantially lowered compared with known embodiments, and to which access from the sidewalk is done using a single intermediate step, namely by crossing only two steps.
  • the invention also relates to a bogie which, only carrying, is produced in such a way that, even in the absence of a primary elastic suspension, the load is evenly distributed between the 4 wheels which can then be of very small diameter, this which allows a significant lowering of the level of the floor, and this of most of its surface.
  • Another advantage of the invention resides in the fact that the reduction in the number of steps, to only two, allows the suppression of the downpipe which exists in known constructions, access pits to the door and makes execution possible. of the lowered floor on one and the same level and this even in the vicinity of the doors, the two steps to be crossed using the only necessary intermediate step which is retractable and can be placed outside the vehicle.
  • the elimination of the downspout also makes it possible to produce the side rail of the rectilinear floor, which is more economical.
  • the invention relates to a railway vehicle, in particular an urban vehicle, the body of which, consisting of one or more sections, comprises a floor bordered on each side by a spar, walls fitted with doors and windows, a roof, and is supported by at least two bogies of which at least one, non-motorized, is only load-bearing, this load-bearing bogie being provided with small diameter wheels allowing a significant lowering of the level of the vehicle floor in line with the area corresponding to this bogie, l lowering being sufficient for a single step, placed at a level located halfway between the roadway and the vehicle floor, is necessary to allow access, respectively the exit of passengers from the vehicle, characterized in that the lowered floor surface is flat, in the sense that it is free from stairwells, the floor edge spars being, from one end to the other of the area of the vehicle where the floor is at lowered, located at the same level and in that the step is retractable and is placed in the position of use simultaneously with the opening of the corresponding door.
  • Fig. 6 shows the case of a tram trailer.
  • FIGs. 7 and 8 are detailed views of a vehicle access door, FIG. 7 being a partial plan view, FIG. 8 a vertical transverse partial section.
  • Fig. 9 is a vertical section view in the longitudinal axis of the front of the vehicle.
  • Fig. 1 shows, by way of example and schematically, a bogie carrying great security in the sense that it can cross zones where the two rails of the track are left, and being equipped with small wheels necessary for the production of the vehicle.
  • This carrier bogie consists of two longitudinal beams (1) and (2) which each have at its ends two front wheels (3 and 4) and rear (5 and 6). In the case of this figure, these wheels are shown being mounted in cantilever at each end of the two longitudinal beams. They are therefore all independent. Another constructive solution would have been possible, in particular by connecting the two front (3 and 4) and rear (5 and 6) wheels to each other by an axis fixed to the ends of the longitudinal beams (1 and 2) by a ball joint allowing vertical movements independent of the wheels.
  • the bogie according to this figure is shown without brakes. It goes without saying that the wheels can be fitted with brakes, the action of which can be carried out on the outer tire or by means of a disc.
  • the two longitudinal beams (1 and 2) are connected to each other by a first transverse beam (7) which, in the case of FIG., Is welded at (8) at one of its ends, in the middle of the length of the beam (2), while at the other end (9) the connection in the middle of the beam (1) is made by means of a guide bearing allowing an oscillation of the longitudinal beam (1) around the horizontal axis of the first transverse beam (7).
  • This degree of freedom allows - without resorting to an elastic suspension of the wheels - the circulation of such a bogie on left tracks, namely on two rails which are not in the same plane.
  • the two longitudinal beams (1 and 2) remain parallel to the corresponding rails, the difference in angle existing between them being absorbed by a rotation taking place at the level of the bearing (9).
  • the first transverse beam (7) comprises an abutment support (16) represented here by a vertical tube rigidly welded to this first transverse beam.
  • This support ends with a rotary stop (15) which carries a second transverse beam (10) in the middle.
  • This connection is made in such a way that this second beam can oscillate around a vertical axis but not tilt.
  • This second transverse beam (10) ends at its two ends (11 and 12) by a support receiving an elastic suspension (13-14) represented here in the form of a coil spring, on which rests the body of the vehicle not -represented in the drawing.
  • an elastic suspension 13-14
  • Fig. 1 shows a schematic arrangement in which the two transverse beams (7 and 10), the stops (16 and 15), the elastic suspensions (13 and 14) are shown for clarity of the drawing, these parts being arranged one above the other others. In fact, in reality, these pieces are nested one inside the other.
  • the first transverse beam is hollow and has the second inside, the lower bearing surfaces of the springs are at the level of the underside of the longitudinal beams (1 and 2), the upper faces being a little higher than the level of the wheels.
  • This bogie makes it possible to balance the loads on the 4 wheels, without having to resort to a significant primary elastic suspension which should allow the compensation of the warping of the track.
  • This particular arrangement allows the production of wheels of very small diameter, therefore also that of railway vehicles whose floor (19) is clearly lowered over its entire surface in the case of trailers (fig. 6), and over almost its entire surface. in the case of vehicles comprising a motor bogie (18) fig. 2, and two motor bogies (18) fig. 3, 4, 5.
  • This arrangement has the advantage of making the floor in the entire area where it is lowered on one and the same level, even in the vicinity of the access doors, and of allowing access by a single retractable intermediate step placed out of the body, as shown in figs. 7 and 8.
  • the floor of the box rests on a beam comprising a rectilinear spar at the edge of the floor (21) which extends from one end to the other of the lowered part of the box, without being interrupted by a well. downhill to a step.
  • fig. 9 shows one end of the vehicle comprising a motor bogie (18) whose wheel diameter must be sufficient to obtain the necessary grip, which means that the level of the floor covering the motor bogies is significantly higher than that of the rest of the vehicle which includes a staircase (33) having - in this figure - 2 intermediate steps for providing access for people to the seats (30) and (32), a handrail (34) facilitating the passage of the stairs.
