Definitions

  • the invention also relates to a vehicle, more particularly a railway vehicle, comprising such a bogie.
  • a rail vehicle and in particular in a rail vehicle intended for intra-urban transport such as, for example, trams, it is desirable to limit the size of the bogies in order to increase the internal space accessible to passengers in the cars, while at the same time keeping a small footprint of the rail vehicle on the track.
  • the reduction in the size of the bogies under the body makes it possible to keep a lowered floor, that is to say extending substantially at the same level over the entire surface of the vehicle and fairly close to the ground. This facilitates the movement of travelers between the cars and access to the vehicle from the outside, in particular for travelers having difficulties in moving and / or goods, while maximizing the available space, for example to maximize the number. seats installed to the right of the bogie.
  • the volume to be left free under the body is particularly important in the case of rotary bogies, that is to say when the body is mobile in rotation relative to the bogie.
  • the space required to allow such rotation while maintaining a lowered floor is a heavy constraint on the design of the bogies.
  • Such a bogie makes it possible to have a railway vehicle comprising an integral lowered floor, while maintaining an acceptable size on the track, in particular as regards the lateral size.
  • the invention also relates to a vehicle comprising at least one bogie as described above and at least one vehicle body carried by the bogie.
  • the figures 1 and 2 represent a bogie 10 of a vehicle, more particularly of a railway vehicle, according to one embodiment of the invention.
  • the bogie 10 is intended to equip a vehicle, more particularly a vehicle guided by track, for example, a railway vehicle, such as a tram or a tram-train.
  • a longitudinal direction X is defined according to the ordinary direction of movement of the vehicle, an elevation direction Z perpendicular to a running plane of the vehicle and a transverse direction Y orthogonal to the longitudinal direction X and to the direction d Z elevation.
  • the bogie 10 is suitable for being installed on a rail vehicle with a lowered floor.
  • the rail vehicle includes at least one car, each car including a body defining a floor.
  • Each floor extends at the same level to within 30 mm in the direction of elevation Z, including to the right of the bogie 10.
  • the floor has in particular at each point a local slope of less than 3%, advantageously 2% with respect to a horizontal plane.
  • the rail vehicle comprises a large number of seats located to the right of the bogie, in particular at least sixteen seats on the same floor to the right of the bogie, thanks to the lowered floor.
  • the floor extends for example to a height substantially between 350 mm and 380 mm from the ground, the height being measured in the direction of elevation.
  • the bogie 10 is a fixed bogie, that is to say a bogie intended to support the body of the rail vehicle without allowing significant relative rotational movement (that is to say here of amplitude greater than 2 ° to within 0.5 °) of the body relative to the bogie 10 around an axis of rotation substantially parallel to the direction of elevation Z.
  • the bogie is said to be fixed when it is intended to support the body of the rail vehicle without allowing movement of amplitude greater than 4 °, within 0.5 °.
  • the bogie 10 comprises a bogie frame 12, as well as four wheels 14, four motors 16 and four reducers 18.

  • the cross members 30 and the side members 32 have an I-shaped section in a plane orthogonal to their direction of elongation. By this is meant that their section in this plane has a shape comprising a main section extending in the direction of elevation Z and two transverse sections connected to the ends of the main section in their respective midpoints, the transverse sections being orthogonal to the section main.
  • the crosspieces 30 and the side members 32 have an L-shaped, T-shaped, Z-shaped section, or another shape giving them suitable torsional resistance.

  • the joints are in particular pivot links, so that the end part 24 is movable relative to the frame 12 in the direction of elevation Z.
  • the primary suspension system 31 is thus adapted to allow a deflection of the axle boxes 34 relative to the chassis 12 only in an elevation direction, which makes it possible to keep a small footprint of the primary suspension system 31.
  • the deflection of the Primary suspension system restricted to movement in the direction of elevation Z is completed by the flexibility of the frame 12, conferred by the shape of the cross members 30 and the side members 32.

  • Each axle box 34 contains one of the hubs 38 as well as the reduction gear 18, which mechanically drives the hub 38 under the action of the associated motor 16.
  • the integration of the reduction gear 18 in the axle box 34 makes it possible in particular to limit the size of the bogie in the transverse direction Y.
  • Each reducer 18 is, for example, fixed on the one hand oscillating on the axle and on the other hand linked to the bogie frame by a reaction rod.
  • the end cross members 36 are metal beams of elongated shape, extending substantially parallel to the transverse direction Y, and capable of advantageously having an I-section as defined above.
  • Each hub 38 is rotatably mounted in the respective axle box 34, around an axis of rotation substantially parallel in the transverse direction Y, and carries a single wheel 14.

  • the use of independent hubs 38 for the four wheels 14 makes it possible to free up the space located above the wheels. end cross members 36 and increases the free volume to the right of the bogie 10.
  • the end cross members 36 define between them a longitudinal space E ', the longitudinal space E' extending between the beams in the longitudinal direction X, the wheels 14 being fully positioned inside the longitudinal space E ' in the longitudinal direction X. That is to say that each wheel 14 is located in a space extending between the two end cross members 36 in the longitudinal direction X.
  • Each fifth wheel 26 is connected to the frame 12 by elastic supports. This makes it possible in particular not to restrict the torsional flexibility of the frame 10.
  • the fifth wheel 26 further comprises a respective secondary suspension system adapted to connect the fifth wheel 26 to a rail vehicle body carried by the bogie 10.
  • Each secondary suspension system comprises a shock absorber 39A and two groups of springs 39B, each connecting the body to the fifth wheel 26.
