Definitions

  • the present invention relates to a railway vehicle comprising two sets of two axles which can be oriented relative to the body.
  • the wagons intended for the transport of passengers almost all have two bogies formed by two axles and oriented relative to the body around a central pivot.
  • the load of the wagon is applied to the center of each bogie so that the load of the wagon body is in fact concentrated at two points and with a cantilever between the central point of support and the ends of the bogie since the load is transferred from the central point of the bogie to the axles.
  • Railway vehicles are also known which comprise only two axles with radial guidance, that is to say axles whose axis is guided so as to always pass through the instantaneous center of rotation of the track.
  • Radial guidance has the advantage of eliminating screeching in curves and undulating rail wear.
  • the use of radial axles arranged at the end of railway vehicles also makes it possible to load the axles directly and not centrally, as in the case of a bogie. The load is then distributed without overhang. However, for heavy vehicles, it is imperative to increase the number of wheels to stay below the limit load tolerated by the infrastructure.
  • the subject of the present invention is a railway vehicle comprising sets of two axles which can be oriented relative to the body in which the load of the body is supported by the rolling elements without any problem of overhang while making it possible to support bodies of significant weight.
  • the rail vehicle according to the invention is notably remarkable in that the load of the body is applied in the vertical plane of each axle at two points close to the wheels. In this way, the load is applied at four points for each of the sets of two axles, which eliminates the problems of overhang whether in the longitudinal or transverse direction; moreover, the axle load being lower, for example 22.5 tonnes, it is possible to support wagons of significant weight.
  • the axle may be an axle which supports the two wheels arranged on either side of the rail vehicle; the axle can also be constituted by a cross member carrying the wheels at its two ends and arranged in a plane different from the horizontal plane of the axis of the wheels.
  • said cross member is disposed above the axis of the wheels, which makes it possible to reduce the distance between the bottom of the body and the axle and to raise the support points of the body.
  • the cross member is arranged below the axis of the wheels, which allows lower the body and make, for example, double-decker passenger wagons.
  • the load of the body is applied to each of the axles by means of sideboards; torsion springs or ball and roller bearings can also be used.
  • the invention applies more particularly to railway vehicles with integral radial guidance, that is to say railway vehicles which comprise two assemblies each comprising two axles which can be oriented with radial guidance.
  • FIGS 1 and 2 there is shown schematically a railway vehicle comprising two sets of two axles with radial guidance.
  • This vehicle the central part of which has not been shown, comprises a body 1 supported by two assemblies 11 and 12, each comprising two axles 2 carrying wheels 3.
  • Each axle may be an axle-axle integral with the wheels 3, but it may also be cross-members arranged above the plane of the axis of the wheels 3 and carrying the latter. They may be independent wheels or the crosspieces can be fixed on mounted axles made in one piece with the wheels 3.
  • Each set 11 and 12 is arranged in the vicinity of one end of the body 1.
  • the two axles 2 are connected by a horizontal connecting bar 4, the ends of which are mounted at articulation at 7 on the center of the axles or cross members 2 and which is mounted at articulation around a first vertical axis 8 secured to the body and arranged in the longitudinal median plane 13 of the latter.
  • each axle 2 has a connecting bar which is fixed to the latter orthogonally in its middle 7.
  • the first bar 5 has its other end fixed to articulation on the second bar 6 at a point of articulation 10.
  • the second bar 6 comprises an extension 14 beyond the point 10 of articulation with the first bar 5 and the free end of this extension 14 is fixed at articulation around a second vertical fixed axis 9 secured to the body 1; this second fixed axis is also arranged in the longitudinal median plane 13.
  • the second vertical fixed axis 9 can be located towards the end of the wagon relative to the first vertical axis of rotation 8 as is the case in the embodiment shown; according to a variant, this second fixed vertical axis of rotation can be located inside, that is to say towards the center of the vehicle with respect to the first fixed vertical axis.
  • the two second vertical axes are outside the first two vertical axes and in the second embodiment they are inside.
  • each set 11 and 12 is designed in such a way that the distance (a) separating the first two fixed axes 8 from the two sets, the distance (b) in straight alignment between the center 7 of an axle and the first fixed articulation axis 8 and the length (n) of the extension 14, that is to say the distance between the second fixed vertical axis 9 and the articulation point 10 of the two bars of link 5 and 6, verify at least approximately the following relation:
  • This variation in length is very small; so for example for a minimum radius of curvature of 30 meters a distance between set of axles (a) equal to 10 meters, half a distance between axles of the same set (2) equal to 1 meter and an extension length (b) equal to 0.25 meters, the maximum variation in length articulation bars 5 and 6 is 6.10 ⁇ 4m and we ensure the radiality of the two axles to 6.10 ⁇ 3 degree.
  • elastic blocks can be used to connect the articulation arms to the axles or the two ends of the link arm to the axles.
  • the load is carried out on each of the axles at two points located near the wheels, so that for each set there are four support points which are not arranged in the longitudinal median plane 13 as in the case of a bogie but on the sides of the vehicle which eliminates the drawbacks due to the overhang.
  • the first fixed vertical axis of rotation 8 then does not support any load and it only carries out the guiding of each assembly without any vertical force; this also applies to the second vertical axis of rotation 9.
  • connection between the body 1 and the four axles 2 is carried out with devices having a low coefficient of friction; it is possible, for example, to use reading boards of known type.
  • the load of the rail vehicle is applied to each axle at two points close to the wheels by means of torsion springs.
  • Figures 4 and 5 illustrate an embodiment of the invention and show an assembly of two axles with radial guidance as described above.
  • Figure 5 is a top view on which the load distribution elements have been shown only on the right for reasons of clarity and
  • Figure 4 is a side view, the wheel on the left being seen from the outside and the wheel on the right being seen from the inside.
  • the car body is shown schematically by a part 41; on this part is fixed a central pivot 42 which corresponds to the first fixed vertical axis of rotation 8; the part 41 also supports a vertical axis of rotation 43 which corresponds to the second vertical axis of rotation 9.
  • a horizontal bar 44 is articulated at its two ends in the middle of each axle at 45 and it is also fixed in its middle on the pivot 42. This horizontal bar therefore corresponds to the horizontal connecting bar 4 above.
  • each axle each consist of a set of two bars 46 (respectively 48) fixed to the ends of the axle and connected to a part 47 (respectively 49).
  • These two parts 47 and 49 are articulated one on the other about a non-visible central vertical axis corresponding to the articulation point 10.
  • One of these parts, part 49 in the example shown, comprises a extension 51 beyond its central axis of articulation; the end of this extension 51 is mounted at articulation around the pivot 43 constituting the second fixed vertical axis.
  • the load of the body is distributed over the two axles of each assembly in the vicinity of the wheels.
  • one end of the body represented by the part 41 has two wings 52 at each of the wheels 54 and 55; these wings are used to transfer the weight of the body to each of the axles in each set.
  • this weight transfer is advantageously carried out by means of readers 53 secured to the crosspiece 56. These readers are friction parts used in the railway sector to receive part of the weight of the body and transmit it to the sleeper.
  • sideboards makes it possible to obtain a load transfer while allowing any movement of the two parts bearing on one another.
  • torsion springs can also be used; these torsion springs also make it possible to absorb the relative movements of the body and the axle, and the use of these torsion reports also makes it possible to obtain a suspension and to remove the primary suspensions 57 which can be seen at each wheel in Figure 4.
  • Ball or roller tracks can also be used in place of side rails to transfer the load from the box.
  • the use of these raceways has the advantage that they have a lower braking torque than the sideboards.
  • the invention therefore makes it possible to better distribute the load and also to eliminate the beams which transmit the load from the center of the bogie to the axles in the case of a bogie; this simplifies the production of the assemblies with respect to the bogie and this results in a reduction in the structure of these assemblies.
  • the distribution of the load at four points limits the roll movements.
  • the invention Compared to vehicles comprising two radial axles as described above, the invention practically makes it possible to double the vehicle load by maintaining a constant axle load; for example, if we accept a load of 22.5 tonnes per axle, it is possible to make heavy rail vehicles.
  • Another advantage of the invention lies in the reduction of the unloading rate in the buy-backs of cant, that is to say that in the entrances to curves with cant, no wheel is unloaded because the two axles are independent.
