Definitions

  • the present invention relates to a railway vehicle bogie of the type comprising a chassis and two axles, the chassis comprising two longitudinal members extending in a longitudinal direction, each axle comprising a pair of wheels each provided with a tire and a connecting device. extending between said wheels, each axle comprising an axle housing extending in a transverse direction substantially perpendicular to the longitudinal direction and at least partially surrounding the connecting device.
  • the invention also relates to a railway vehicle of the type described above.
  • Such a truck in which the wheels are provided with a tire, said carrier tire, is particularly intended for a railway vehicle of the subway or tramway type, running on running tracks.
  • the structure of the bogie remains complex due to the need either to elastically articulate different parts of the bogie frame between them, or to introduce a so-called primary suspension stage between the chassis and the axles.
  • it is in particular planned to elastically articulate the side members to one or more cross members connecting the side members together. Consequently, the assembly of the bogie is complicated by the mounting of the elastic hinge elements or by the mounting of the primary suspensions.
  • One of the aims of the invention is to overcome these disadvantages by proposing a simplified bogie structure whose assembly is facilitated.
  • the invention relates to a bogie of the aforementioned type, in which the chassis side members are connected to each other by the axles, the axle housing of each axle being rigidly fixed to each of said longitudinal members.
  • axle housings By providing spars extending in the longitudinal direction interconnected by the axle housings, that is to say whose chassis does not include additional cross connecting the spars together, we can take advantage of the flexibility of beams to provide the bogie with the ability to twist about a longitudinal axis without an elastic hinge element in the bogie frame or between the side members and the axles.
  • the axle housings can be fixed rigidly to the longitudinal members, that is to say without elastic hinge elements, which simplifies the structure of the bogie and its assembly.
  • the invention therefore makes it possible to pass from a bogie with articulated chassis or a bogie with primary suspension, to a flexible bogie while retaining the same capacities in terms of suspension and torsion.
  • the invention also relates to a railway vehicle comprising a bogie as described above.
  • the term “longitudinal” is defined with respect to the direction of movement of a railway vehicle, that is to say according to the direction in which the runways extend over which the railway vehicle is traveling.
  • the term “transversal” is defined by a direction corresponding to the width of a railway vehicle, that is to say a direction substantially perpendicular to the longitudinal direction and extending in a horizontal plane when the railway vehicle is traveling on horizontal runways.
  • the term “elevation” is defined by a direction substantially perpendicular to the longitudinal and transverse directions, that is to say a substantially vertical direction when the railway vehicle is traveling on horizontal running tracks.
  • a railway vehicle bogie 1 comprising a chassis 2 and two axles 4 mounted on the chassis 2 is described.
  • the frame 2 comprises two longitudinal members 6 each extending in a longitudinal direction and spaced apart from each other in the transverse direction.
  • Each spar 6 is formed by a metal profile, for example steel.
  • the profile has in cross section, that is to say in a plane extending in a transverse direction and in a direction of elevation, the shape of a l, as shown in FIG. figure 3 .
  • the cross section of the spar 6 comprises a web 8 extending in a plane extending in the longitudinal direction and in the elevation direction and two flanges 10 extending on either side of the core 8.
  • the flanges 10 extend in planes substantially perpendicular to the plane of the core 8, that is to say in planes extending in the longitudinal direction and in the transverse direction.
  • the profile comprises an upper flange 10a and a lower flange 10b respectively extending above and below the core 8 in the elevation direction.
  • the spar 6 is able to undergo a twist around an axis A extending along the longitudinal direction along the core 8 substantially equidistant from the two flanges 10.
  • the twist around the axis A can go up to 1 ° for a bogie of substantially 2 m wheelbase.
  • Such a torsion occurs in particular when crossing a lane left of 10 mm / m rolling on the auxiliary wheels or in case of puncture of a carrier tire, as will be described later.
  • the spar used in the bogie according to the invention does not have a closed section, as is the case in the longitudinal members having a box structure, which makes it possible to give it this torsion capacity unlike spars having a structure of box, which are particularly rigid.
  • the profile described above has the shape of a l, it is understood that this profile could have a different shape as this shape is adapted for the spar has some flexibility or flexibility around its longitudinal axis A.
  • each spar 6 comprises two longitudinal end portions 12 extending at each end of the spar 6 in the longitudinal direction.
  • the longitudinal end portions 12 each extend in a direction transverse to the outside of the bogie 1.
  • the longitudinal end portions 12 are arranged to each carry a guide wheel 14, as shown in FIG. figure 1 .
  • Each guide wheel 14 extends substantially transversely and is arranged to bear against a guide surface (not shown) extending on one side of the raceways on which the railway vehicle is traveling.
  • the railway vehicle does not run continuously on rails and bogie guidance is necessary, especially in bends, and this guidance can be achieved by guiding surfaces extending on either side of the raceways, and by contact of the guide wheels 14 with these guide surfaces.
  • the guide wheels 14 are for example each provided with a tire and is rotatable about an axis Z extending in the direction of elevation with respect to the longitudinal end portions 12.
  • Each spar 6 further comprises attachment areas 16 for fixing the axles 4 and possibly a motor 18, as will be described later.
  • the attachment areas 16 are for example provided with one or more orifices in the upper sole 10a for screwing a screw 19 or bolting a bolt in the sole as will be described later.
  • Each axle 4 comprises two wheels 20 connected to a connecting device disposed in an axle housing 22.
  • Each wheel 20 extends at a transverse end of the axle 4 so that the wheels 20 of an axle 4 extend on either side of the longitudinal members 6 of the frame 2, as shown in FIG. figure 1 .
  • Each wheel 20 is provided with a tire 21, said carrier tire, and is rotatable about an axis of rotation B extending in a substantially transverse direction.
  • Each axle 4 may further comprise two auxiliary wheels 23 each disposed next to one of the wheels 20. Such auxiliary wheels 23 are arranged to allow the circulation on rails, for example in areas devoid of raceways for the tires. carriers 21.
  • the connecting device extends transversely from one wheel 20 to the other (or from an auxiliary wheel 23 to the other) and is for example formed by one or more shafts integral in rotation with the wheels 20, and for example driven in rotation by a gearbox 24 disposed between the longitudinal members 6 in the case of a motor bogie, as will be described later.
  • the shaft (s) and the gearbox (24) are housed, at least partially, and rotatable in the axle housing (22) which extends at least from one spar (6) to the other.
  • the axle housing 22 thus forms a sheath whose shape is adapted to receive the shaft (s) and the gearbox 24.
  • the axle housing 22 is for example open for the passage of a shaft.
  • the axle housing 22 is rigidly attached to each spar 6 and provides a connection between these spars 6. Rigid attachment means that the axle housing 22 is not movable relative to the spars. 6.
  • the fastening of the axle housing 22 to a spar 6 is in a fixing zone 16 thereof for example by screwing at least one screw 19 or bolting a bolt passing through a plate 28 of the axle housing 22 in the hole provided for this effect in the upper sole 10a of the spar.
  • fixing the axle housing 22 of an axle 4 on a spar 6 is by two screws 19 extending on either side of the axle housing 22 in the longitudinal direction.
  • the figures show a bogie 1 in which the axles 4 are fixed on the upper sole 10a of the longitudinal members 6, the axles therefore extending above the longitudinal members 6.
  • the axles 4 could be fixed on the lower flange 10b of the longitudinal members 6 and extend below them.
  • the axle housings 22 are fixed rigidly to the longitudinal members 6, each in the vicinity of a longitudinal end portion 12 of the longitudinal members 6, so that the axles 4 and the longitudinal members 6 form a rigid frame in the direction of elevation and according to the transverse direction.
  • This assembly is, however, able to undergo a twist about a longitudinal axis A 'extending substantially equidistant from the longitudinal members 6 between them due to the flexibility of the longitudinal members 6 along said longitudinal direction, as described above.
  • the bogie 1 according to the invention is therefore able to take up the forces in the direction of elevation thanks to the elasticity of the tires 21 and to pass the left lanes thanks to this ability to undergo a twist about a longitudinal axis then same as the bogie 1 is devoid of suspension element and elastic hinge element.
  • the bogie 1 is a motor bogie comprising a motor 18 arranged to drive the wheels 20 in rotation through the gearboxes 24.
  • the motor 18 is connected to the reducers via the input shafts 26.
  • the motor 18 is placed, at least partially, in a motor casing 30 extending substantially transversely from a spar 6 to the spur. the other is placed in the longitudinal direction between the axles 4.
  • the engine casing 30 is fixed rigidly to each of the longitudinal members 6.
  • rigid attachment means that the engine casing 30 is not movable relative to the longitudinal members 6 and that there is no suspension element or elastic articulation provided between the motor housing 30 and the longitudinal members 6.
  • the housing of motor 30 is fixed by screwing or bolting in a fastening area 31 of the longitudinal members 6.
  • the motor housing 30 also participates in the connection of the longitudinal members 6 between them.
  • the bogie frame 2 described above comprises only two longitudinal members 6 and no mechanically welded connection between these two side members, such as a cross member or the like, this function being fulfilled by the axle housings 22, and if necessary, the motor housing 30.
  • Such a chassis structure makes it possible to provide the latter with the desired flexibility around the longitudinal axis A ', in particular when crossing the left-hand lanes when the bogie is traveling on the auxiliary wheels 23 or
  • the mounting of the chassis is thus particularly simple since it can be obtained by simple screwing or bolting operations. For example, eight screwing or bolting operations are sufficient to obtain the bogie when each axle housing 22 is fixed to each spar 6 by two screws or two bolts.
  • the bogie has been described as comprising a motor 18, that is to say a motorized bogie, driving the wheels 20 of the two axles 4 in rotation.
  • a motorized bogie driving the wheels 20 of the two axles 4 in rotation.
  • the invention could be applied to a bogie without motor, whose wheels are rotated due to the drive by another motorized bogie, or to a bogie whose motor does not rotate the wheels than a single axle 4 on both.
  • the invention also relates to a railway vehicle comprising one or more bogies as described above.
  • a railway vehicle is for example a metro or a tramway arranged to circulate on runways lacking, at least in part, rails and comprising on the sides, in at least some areas, guide surfaces.
