Definitions

  • the present invention relates to a railway vehicle comprising at least one car, each car comprising a car body, the body being supported by at least one bogie comprising air cushions and side members.
  • the body and the bogie are linked together by at least one load cross member.
  • the invention applies more particularly to railway vehicles of the metro type, interregional trains and the like.
  • WO 2016/079090 A1 describes a rail vehicle cross member for the articulation of a rail vehicle body on its bogie.
  • CN 103 661 472 A describes a sleeper for a railway vehicle.
  • cast iron components Compared with steel components, mechanically welded or cast steel, cast iron has advantageous characteristics concerning its flowability during the manufacturing process. Thus, cast iron allows parts with more complex shapes to be produced in one piece.
  • This component is the cross member connecting the two side members of the vehicle body and supporting the bogie.
  • a bogie In a bogie, several active components are integrated, for example motors to drive the vehicle, air supply systems and others.
  • active components for example motors to drive the vehicle, air supply systems and others.
  • One of the aims of the invention is to overcome these drawbacks by proposing a railway vehicle having a connection between a body and a bogie allowing simple integration of active components.
  • the invention relates to a rail vehicle according to claim 1.
  • the rail vehicle is according to any one of claims 2 to 8.
  • the terms “on”, “under”, “above”, “below” are defined with respect to a direction of elevation of a rail vehicle when it is arranged on rails, c that is to say a substantially vertical direction when the train is traveling on horizontal rails.
  • the longitudinal direction is defined by the direction of travel of the rail vehicle and the transverse direction is the direction substantially perpendicular to the longitudinal direction and the direction of elevation of the rail vehicle.
  • a bogie comprising two longitudinal members 3a, 3b which extend in the longitudinal direction and which support axles not shown.
  • the longitudinal members 3a, 3b carry at least one air cushion 1a, 1b each, the air cushion 1a, 1b substantially in the center of the longitudinal members 3a, 3b in the longitudinal direction.
  • the longitudinal members 3a, 3b are, at the longitudinal ends and at their center, connected by crosspieces 5a, 5b and 5c to one another.
  • the crosspieces 5a, 5b and 5c extend substantially in a transverse direction perpendicular to the longitudinal direction.
  • the cross 5c provides the connection with a pivot 7.
  • the bogie comprises one or more active components, for example a motor, an air supply system and the like.
  • the bogie is given as an example only and could be different.
  • the bogie could be formed by two half-frames hinged together and each supporting an axle.
  • the load cross member 2 extends substantially along the transverse direction above the bogie.
  • the air cushions are capable of attenuating the vertical movements of a body 9 and therefore behave like a shock absorber.
  • the load cross member 2 is molded of cast iron, for example spheroidal graphite cast iron. Preferably, it is made in one piece, which allows the fact of making the cross member in cast iron.
  • the load cross member 2 is, inter alia, linked by shock absorbers 4a, 4b to the bogie, the shock absorbers extending substantially in the direction of elevation.
  • the cross 2 is connected to the bogie by the pivot 7, anti-roll rods 6a, 6b, the rods extending substantially in the direction of elevation.
  • the anti-roll rods 6a, 6b comprise two articulations each, one articulation connecting the rod 6a, 6b to the load cross member 2, the other articulation linking the rod 6a, 6b to the bogie.
  • the axes of the joints extend substantially in the transverse direction.
  • the load cross member 2 comprises at each of its transverse ends two fixing surfaces 8a, 10a and 8b, 10b forming between them an angle.
  • the two attachment surfaces are perpendicular to each other respectively.
  • the load cross member 2 is fixed by these fixing surfaces 8a, 8b, 10a, 10b to the body 9 of the rail vehicle.
  • the body 9 of the vehicle is for example of aluminum material.
  • the fixing between the load cross member 2 made of cast iron and the body 9 is preferably carried out by rivets or any other technically possible fixing means. However, the fixing is not carried out by welding due to the heterogeneity of the assembled materials.
  • the load cross member 2 extends between an upper face 12 and a lower face 14, the faces containing a longitudinal direction and a transverse direction, the upper face 12 extending above the face lower 14.
  • the load cross member 2 comprises at least one concavity 16a, 16b, which extends from the upper face 12 in the direction of the lower face 14.
  • the concavity 16a, 16b makes it possible to reduce the quantity of material of the cast iron, this which makes the load cross member 2 lighter, while retaining satisfactory mechanical strength.
  • the concavity 16a, 16b comprises a surface between the upper face 12 and the lower face 14 which forms the bottom 17a, 17b of the concavity.
  • the concavity 16a, 16b constitutes a free space which extends, in the direction of elevation, between the bottom 17a, 17b of the concavity 16a, 16b and the upper surface 12 and which extends, in the longitudinal and transverse directions , between walls 19a, 19b of the concavity 16a, 16b.
  • at least one concavity 16a, 16b is located substantially above one of the air cushions 1a, 1b.
  • the free space in the concavity 16a, 16b is, in a preferred embodiment, at least in part, used to accommodate active components, for example an air supply system 18 or the like. As described above, the space available in the bogie is small. By accommodating active components in the concavity 16a, 16b of the load cross member 2, more space is available for other components above and below the load cross member 2.
  • At least one concavity is located substantially above the air cushion 1a, 1b.
  • the concavity 16a, 16b has at least one orifice 20a, 20b for accommodating the air supply system 18 in the concavity 16a, 16b.
  • the orifice 20a, 20b arranged substantially in the middle of the concavity 16a, 16b, extends in the direction of elevation between the bottom 17a, 17b of concavity 16a, 16b and the lower face 14.
  • the air supply system 18 comprises tubes, visible in the figure 3 .
  • the tubes are, at least in part, accommodated in the concavity.
  • the air supply system 18 is connected by the orifice to the air cushion 1a, 1b which is located below the concavity 16a, 16b.
  • the air supplying the air cushions 1a, 1b is transmitted through the tubes of the air supply system 18 to the orifices 20a, 20b and then into the air cushions 1a, 1b.
  • the load cross member 2 comprises, in a preferred embodiment, one or more other concavities. Consequently, the weight of the load cross member 2 is further reduced.
  • the additional concavities are arranged so as not to degrade the mechanical resistance of the load cross member 2.
  • the load cross member 2 further comprises a bore 22 extending in the direction of elevation from the lower face 14, disposed substantially in the center of the load cross member 2.
  • the bore is arranged to receive a pivot 7 integral to the bogie. The purpose of the pivot is to transmit longitudinal and transverse forces between the load cross member 2 and the bogie.
  • At least one bore 24 is provided to accommodate a centering pin 26.
  • the bore 24 is, for example, arranged in the direction of elevation above the cushion air 1a, 1b.
  • the purpose of the centering pin 26 is to center and orient at least one of the air cushions 1a, 1b relative to the load cross member 2, in particular relative to the orifice 20a, 20b to accommodate the system d air supply 18.
  • the load cross member 2 comprises for each air cushion 1a, 1b, at least two bores 24 which are capable of accommodating a centering pin 26 each.
  • the bores 24 are distributed annually around the orifice 20a, 20b and they extend from the lower surface 14 in the direction of elevation above the air cushion 1a, 1b.
  • the weight of the car is transmitted to the load beam 2 by its body 9 which is fixed by fastening surfaces 8a, 8b, 10a, 10b to the load beam 2.
  • This force applied mainly according to the direction of elevation is transmitted by the air cushions 1a, 1b to the bogie.
  • longitudinal and transverse forces appear. They are mainly transmitted from the bogie in the load cross member 2 and vice versa by the pivot received in the bore 22.
  • shock absorbers 4a, 4b partially absorb the sudden forces between the bogie and the load cross member 2 when the train is running.
  • anti-roll rods 6a, 6b By the configuration of anti-roll rods 6a, 6b described above, during the advancement of the rail vehicle, the rods tolerate a pitching movement relative to the longitudinal direction, but they prevent a rolling movement relative to this direction.
  • the structure of the air supply system 18 could be different from that described above as long as the air supply tubes shown in the figure 4 are received only partially or entirely in concavity 16a, 16b.
  • the concavity 16a, 16b is capable, in another embodiment, of accommodating other active components.
