Definitions

  • the present invention relates to a bogie chassis comprising two side members connected by at least one cross member, the bogie being able to be motor or carrier.
  • the bogie frames produced by molding are produced in a single operation, so that the frame is in one piece.
  • Such manufacture requires the use of foundry models, treatment ovens and machining machines, of large dimensions, therefore expensive.
  • the bogie frames are manufactured by mechanical welding from steel sheets.
  • the two beams are made in this way and the cross member (s) can either be made in this way, or consist of tubes.
  • the use of welding to connect the side members and the crosspieces therefore requires, for the entire chassis, the use of a single weldable material, generally steel.
  • the present invention aims to make the chassis modular to facilitate maintenance operations and allow a certain scalability of the chassis design. This object is achieved by the use of mechanical connections, this making it possible to produce components independently such as a spar or a cross member, and then to assemble them by bolting. Two adjacent components can thus be produced in two different materials, incompatible from the welding point of view.
  • each component can be done by molding or by mechanical welding.
  • the production by molding allows the use of foundry models, treatment ovens and machining machines, of small dimensions, and allows the use of a material, a light alloy for example, deemed non-weldable therefore not usable in the case of mechanical welding.
  • the subject of the present invention is a bogie frame comprising two longitudinal members connected by at least one cross member, characterized in that the cross member (s) as well as the longitudinal members have connecting surfaces ensuring, by assembly and bolting, fixed mechanical connections between the side members and the cross member (s).
  • a motor bogie frame has a cross member and a carrier bogie frame has two cross members.
  • the bogie frame may include one or two secondary beams which support part of the torsional force due to braking as well as the forces due to body stops and anti-roll bars, in order to relieve the main beams.
  • Figure 1 shows a perspective and partially exploded view of the first embodiment.
  • Figure 2 shows a perspective and partially exploded view of the second embodiment.
  • FIG. 3 represents, in partial view, a first variant of the second embodiment.
  • FIG. 4 represents, in partial view, a second variant of the second embodiment.
  • this chassis comprises two longitudinal members 10, 20 and a single central cross-member 30.
  • the side members 10, 20 each consist of a beam 11, 21 and a connecting ring 12, 22, the ring 22 of the side member 20 being clearly shown.
  • the cross-member 30 consists of a tube 31 carrying a central pivot 31A and two connecting rings 32, 33.
  • this frame comprises two longitudinal members 10, 20 and two crosspieces 30, 40.
  • This chassis may further comprise a central secondary spar, or as shown, two lateral secondary spars 50, 60, the secondary beam 50 being adjacent to the main beam 10 and the secondary beam 60 being adjacent to the main beam 20.
  • the longitudinal members 10, 20 each consist of a beam 11, 21 and two connecting rings 12, 13; 22, 23, in this figure, only the rings 22, 23 of the spar 20 being clearly represented.
  • the crosspieces 30, 40 each consist of a tube 31, 41 carrying two connecting rings 32, 33; 42, 43, and two brackets supporting a brake support bar 36, only the two brackets 34, 35 and the support bar 36 of the cross member 30 being shown.
  • the secondary beams 50, 60 each consist of a beam 51, 61 and four connecting rings, only the connecting rings 62, 63, 64, 65 of the secondary beam 60 being clearly represented.
  • the fixed mechanical connections between two adjacent crowns are made up of surfaces assembled by bolting, and these surfaces are planar but of course, in order to improve the positioning of the crowns between them, the connections can comprise an interlocking circular.
  • the connections can be made by bolts each passing through the four crowns, for example, the crowns 22, 64, 62, 33.
  • FIG. 3 shows a first alternative embodiment in which the brackets are connected to the brake support bar by means of two connecting plates assembled by bolting, this making it possible to produce the brackets and the bar in different materials incompatible with welding.
  • bracket 35 in partial view, only the bracket 35 is shown.
  • This bracket 35 has at its end a connecting plate 35A, and the bar 36 also has a connecting plate 36A, these two plates 35A, 36A may include a centering.
  • Figure 4 shows a second alternative embodiment in which the support bar is directly connected to the end of a secondary spar, so that the brackets are eliminated.
  • the beam 61 of the secondary spar 60 is extended, beyond the connecting rings, by a protuberance 66 terminated by a connecting plate 66A.
  • the bar 36 has a connecting plate 36A, and the two plates 36A, 66A are connected by bolting.
