Definitions

  • the invention also relates to 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 travelers in cars, while retaining 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 rail vehicle and fairly close to the ground. This facilitates the movement of travelers between cars and access to the vehicle from the outside, especially for travelers who have difficulty getting around, while maximizing the number of seats installed in front of the bogie.
  • the free volume under the body is particularly important in the case of rotary bogies, that is to say when the body is movable in rotation relative to the bogie.
  • the space required to allow such rotation while retaining a lowered floor is a heavy constraint for the design of bogies.
  • Such a bogie makes it possible to have a railway vehicle comprising an integral lowered floor, while maintaining a space requirement on the acceptable track, in particular as regards the lateral space requirement since all the masses are not placed outside the space defined between the wheels.
  • the invention also relates to a railway vehicle comprising at least one bogie as described above, and at least one vehicle body carried by the bogie, the body comprising at least twelve seats arranged in line with the bogie on the same floor, the body also comprising a lowered floor, extending substantially at the same level over the entire floor.
  • the figures 1 and 2 represent a rail vehicle bogie 10 according to a first embodiment of the invention, intended to equip a rail vehicle.
  • a longitudinal direction XX ′ is defined in the ordinary direction of circulation of the rail vehicle, a transverse direction YY ′ orthogonal to the longitudinal direction X-X ′, extending in a horizontal plane in ordinary operation of the vehicle rail, and an elevation direction ZZ 'substantially orthogonal to the transverse direction YY' and to the longitudinal direction X-X '.
  • the bogie 10 is adapted to be installed on a railway vehicle with a fully lowered floor.
  • the rail vehicle comprises at least one car, each car comprising a body defining a floor, and that each floor extends substantially at the same level in the direction of elevation Z-Z ', including at right of the bogie 10.
  • the rail vehicle comprises a large number of seats located at the right of the bogie, in particular at least twelve seats on the same floor at the right of the bogie, thanks to the fully lowered floor.
  • the floor extends for example at a height substantially between 350 and 380 mm from the ground, the height being measured according to 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 movement significant relative rotation (that is to say an amplitude greater than 2 °) of the body with respect to the bogie 10 about an axis of rotation substantially parallel to the direction of elevation Z-Z '.
  • the bogie 10 includes a bogie frame 12, as well as four wheels 14, four motors 16 and four reducers 18.
  • Each motor 16 is associated with a single wheel 14 and with a single reducer 18, so that each motor 16 rotates only the wheel 14 which is associated with it via the corresponding reducer 18.
  • Each wheel 14 is thus mechanically independent of the other wheels 14.
  • the bogie 10 further comprises two end parts 24 situated on the two sides of the chassis 12 in the longitudinal direction X-X ', and two fifth wheels 26 situated on the two sides of the chassis 12 in the transverse direction Y-Y'.
  • the frame 12 also called a frame, comprises two crosspieces 30 and two side members 32 assembled at their respective ends by corner pieces 33 to form a rectangle extending in a plane substantially orthogonal to the direction d 'Z-Z elevation'.
  • the cross members 30 and the side members 32 are for example metal beams of elongated shape, extending respectively substantially in the transverse direction Y-Y 'and in the longitudinal direction X-X'.
  • the cross members 30 and the side members 32 have an I-shaped section in a plane orthogonal to their direction of elongation.
  • their section in this plane has a shape comprising a main section extending in the elevation direction ZZ 'and two transverse sections connected to the ends of the main section in their respective mediums, the transverse sections being orthogonal to the main stretch.
  • the cross members 30 and the side members 32 have an L-shaped, T-shaped, Z-shaped section or another shape giving them a suitable torsional strength.
  • the end portions 24 are connected to the chassis 12 by means of two respective primary suspension systems 31 and two respective joints 35.
  • the joints are in particular pivot connections, so that the end portion 24 is movable relative to the chassis 12 in the direction of elevation Z-Z '.
  • the primary suspension system 31 is thus adapted to allow the axle boxes 34 to travel relative to the chassis 12 only in a direction of elevation, which makes it possible to maintain a reduced bulk of the system. primary suspension 31.
  • the movement of the primary suspension system restricted to one movement in the direction of elevation ZZ ′ is supplemented by the flexibility of the chassis 12, imparted by the shape of the cross members 30 and the side members 32.
  • Each end part 24 comprises two axle boxes 34 fixed to each other by an end crosspiece 36.
  • Each end part 24 carries two of the wheels 14, mounted on respective wheel hubs 38 contained in the boxes.
  • axles 34 as shown in the figure 2 .
  • the axle boxes 34 are metal casings having a substantially parallelepiped shape, and comprising a bevelled side face on the inner side in the transverse direction Y-Y '.
  • 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 end crosspieces 36 are metal beams of elongated shape, extending substantially parallel to the transverse direction Y-Y ', and advantageously having an I-section as defined above.
  • Each hub 38 is rotatably mounted in the respective axle box 34, about a substantially parallel axis of rotation in the transverse direction Y-Y ', and carries a single wheel 14.
  • Each wheel 14 is thus movable in rotation relative to to the chassis 12, around the respective axis of rotation extending in the transverse direction Y-Y '.
  • the end crosspieces 36 extend below the axes of rotation of the hubs 38 in the direction of elevation Z-Z '.
  • the use of independent hubs 38 for the four wheels 14 frees up the space located above the end crosspieces 36 and increases the free volume in line with the bogie 10.
  • each harness 26 is connected to the chassis 12 by a respective articulated arm 39A.
  • the fifth wheel 26 further comprises a respective secondary suspension system adapted to connect the fifth wheel 26 to a body of a railway vehicle carried by the bogie 10.
  • Each secondary suspension system comprises a shock absorber 39B and two groups of springs 39C, each connecting the body to the harness 26.
  • Each motor 16, carried by a corner of the chassis 12, is an electric motor and comprises, in a known manner, a shaft carrying a rotor mounted mobile in rotation in a stator carried by a stator casing, the rotation of the shaft taking place on at least one level of rotation.
  • the shaft is thus movable in rotation relative to the chassis 12 about an axis of rotation extending in the transverse direction Y-Y '.
  • the shaft connects an output of the motor 16 to an input of the reduction gear 18, via a coupling 49, and transmits the torque generated by the motor 16 to the reduction gear 18 and finally to the wheel 14.
  • the wheels 14 define between them a space E, represented on the figures 1 and 2 , the space E extending between the planes of the wheels 14 in the transverse direction Y-Y '.
  • the motors 16 are arranged externally relative to the wheels 14 in the transverse direction Y-Y '. That is to say that each motor 16 is located in a half space extending on the side opposite to the chassis 12 relative to the plane of the wheel 14 associated with the motor 16. The motors 16 are thus arranged outside the space defined by the wheels 14 in the transverse direction Y-Y '.
  • the reducers 18 are positioned internally with respect to the wheels 14 in the transverse direction Y-Y '. That is to say that each reduction gear 18 is located in a half space extending on the same side as the chassis 12 relative to the plane of the wheel 14 associated with the reduction gear 18. The reduction gears 18 are thus arranged inside of the space defined by the wheels 14 in the transverse direction Y-Y '.
  • Each reduction gear 18 is arranged to transmit the rotation of one of the motors 16 to one of the hubs 38 carrying one of the wheels 14.
  • the reduction gear 18 comprises for example a first gear cooperating on one side with a second gear connected to the coupling 49 , and on the other side with a third gear connected to the hub 38.
  • the reducer 18 makes it possible, in addition to adjusting the transmission ratio between the motor 16 and the wheel 14, to transmit the torque from the motor 16 to the wheel 14 without aligning the axes of the hub 38 and of the motor shaft 16 according to the transverse direction Y-Y '.
  • the motor 16 and the wheel 14 are offset in the longitudinal direction XX ′, which reduces the lateral dimensions of the bogie 10.
  • the bogie 10 advantageously comprises four braking devices 60, each braking device 60 being adapted to block the rotation of one of the respective wheels 14.
  • each braking device 60 comprises a brake caliper 62 and two brake pads 64 carried by two members of the brake caliper 62.
  • the braking device 60 is adapted to clamp the brake pads 64 against opposite sides of a brake disc 66, integral with the wheel 14, by means of the brake caliper 62, for blocking the rotation of the wheel 14.
  • Each braking device 60 is disposed entirely below the motor 16 associated with the respective wheel 14 with the braking device 60. That is to say that the braking caliper 62 and the brake pads 64 are located in the half space located under the motor 16 in the direction of elevation Z-Z '.
  • a second embodiment is shown in the figure 3 .
  • the bogie 10 according to the second embodiment differs from the first embodiment by the points described below.
  • the bogie 10 is a pivoting bogie.
  • the bogie 10 is adapted to allow a relative rotational movement between the chassis 12 and the rail vehicle body, about a vertical axis of rotation substantially parallel to the direction of elevation Z-Z ', a maximum amplitude of this relative rotation movement being for example greater than 12 °.
  • the presence of bevelled side faces on the axle boxes 34 makes it possible to improve the amplitude of the rotation of the body.
  • the bogie 10 comprises a load cross member 80 connected to the chassis 12 by the secondary suspension system, and carrying a ball ring 82 adapted to be fixed to the body of the rail vehicle in a manner that can move in rotation about an axis of rotation s 'extending in elevation direction ZZ'
  • the load cross member 80 extends above the chassis 12, in the transverse direction Y-Y '.
  • the load cross member 80 has a central part 84 which carries the ball ring 82, two lateral parts 88 extending the central part 84 externally in the transverse direction Y-Y ', and two ends 90 extending externally relative to the intermediate parts 88 respective in the transverse direction Y-Y '.
  • the central part 84 extends internally with respect to the wheels 14 and to the side members 32, in the transverse direction Y-Y ', that is to say in the space defined by the wheels 14.
  • the end parts 90 extend outside the space defined by the wheels 14.
  • the load cross member 80 is supported on the springs 39C of the secondary suspension system at the ends 90.
  • the central part 84 extends lower than the ends 90 in the direction of elevation Z-Z ', so that 'a height of the ball ring 82 is partially compensated by the lowering of the central part 84. This makes it possible to reduce the bulk associated with the ball ring 82.
  • the load cross member 80 has a thickness e 1 measured in the direction of elevation ZZ 'at the level of the central part 84, greater than a thickness e 2 at the level of the lateral parts 88. This makes it possible to reduce the bulk associated with the load cross member 80 at the level of the lateral parts 88 and the ends 90, that is to say above the chassis 12, where space is crucial, and above the springs 39C, while retaining a sufficient thickness in the central part, at the level of the ball ring 82 carrying the body.
  • the bogie 10 makes it possible to have a railway vehicle comprising an integral lowered floor, while maintaining a sufficiently small footprint on the track, in particular with regard to the lateral or transverse footprint.
  • the motors 16 and the axle boxes 34 are arranged externally, so as to leave a maximum free volume at the right of the bogie to allow the entire lowered floor.
  • the arrangement of the motors 16, the wheels 14 and the axle boxes 34, offset in the longitudinal direction XX ′ makes it possible to minimize the lateral space requirement under the body compared to a direct transmission system, for example .
  • the large free volume in line with the bogie 10 also makes it possible to use the same structure of the bogie 10 for pivoting and non-pivoting applications, the free volume allowing a sufficient amplitude of rotation of the body above the bogie 10 between the axle boxes 34.
