Description

La présente invention concerne un bogie pour véhicule ferroviaire, le bogie comprenant :

  • un châssis présentant un premier côté et un deuxième côté opposé au premier côté, le premier coté et le deuxième côté étant séparés l'un de l'autre par un plan longitudinal médian du châssis,
  • une première roue avant et une première roue arrière situées du premier côté,
  • une deuxième roue avant et une deuxième roue arrière situées du deuxième côté,
  • au moins un moteur disposé du premier coté et fixé au châssis, le ou chaque moteur s'étendant suivant un axe longitudinal entre la première roue avant et la première roue arrière,
  • un essieu avant solidaire des roues avant,
  • un essieu arrière solidaire des roues arrière, et
  • pour chaque essieu, au moins deux organes de suspension primaire de l'essieu par rapport au châssis, dont un premier organe de suspension primaire situé du premier côté du châssis et un deuxième organe de suspension primaire situé du deuxième côté du châssis.
The present invention relates to a bogie for a railway vehicle, the bogie comprising:
  • a frame having a first side and a second side opposite to the first side, the first side and the second side being separated from each other by a median longitudinal plane of the frame,
  • a first front wheel and a first rear wheel located on the first side,
  • a second front wheel and a second rear wheel located on the second side,
  • at least one motor arranged on the first side and fixed to the frame, the or each motor extending along a longitudinal axis between the first front wheel and the first rear wheel,
  • a front axle integral with the front wheels,
  • a rear axle integral with the rear wheels, and
  • for each axle, at least two primary suspension members of the axle relative to the chassis, including a first primary suspension member located on the first side of the chassis and a second primary suspension member located on the second side of the chassis.

Dans les véhicules ferroviaires, il est connu d'utiliser des bogies avec leurs éléments placés symétriquement par rapport au plan médian. La caisse disposée sur le bogie présente en général une disposition des sièges symétriques.In railway vehicles, it is known to use bogies with their elements placed symmetrically with respect to the median plane. The body arranged on the bogie generally has a symmetrical seating arrangement.

Cependant, lorsque la largeur de la caisse est plus faible, une disposition asymétrique de la caisse peut être souhaitée. C'est, par exemple, le cas dans des tramways de faible largeur où il est intéressant de proposer dans la caisse des aménagements avec un siège d'un côté et deux sièges d'un autre côté séparés par un couloir central.However, when the width of the box is lower, an asymmetrical arrangement of the box may be desired. This is, for example, the case in narrow trams where it is interesting to propose in the box arrangements with a seat on one side and two seats on the other side separated by a central corridor.

Cependant, la disposition asymétrique de la caisse sur le bogie est difficile si le bogie est symétrique. Une possibilité est de réduire la largeur du couloir central. En variante, il est connu de prévoir des surélévations de la caisse au niveau des pièces encombrantes du moteur, ces surélévations encombrant le couloir central. Cependant, de telles solutions ne sont pas optimales et empêchent le passage des personnes en fauteuil roulant ou des poussettes dans les couloirs entre les sièges.However, the asymmetrical arrangement of the body on the bogie is difficult if the truck is symmetrical. One possibility is to reduce the width of the central corridor. Alternatively, it is known to provide elevations of the box at the bulky parts of the engine, these elevations bulky central corridor. However, such solutions are not optimal and prevent the passage of people in wheelchairs or strollers in the corridors between the seats.

Par conséquent, un des buts de l'invention est de proposer un bogie permettant une bonne intégration d'un couloir décalé dans un véhicule ferroviaire tout en facilitant la maintenance du bogie.Therefore, one of the aims of the invention is to provide a bogie for a good integration of a staggered corridor in a rail vehicle while facilitating the maintenance of the bogie.

  • un organe élastique interposé entre le bras et le châssis à l'écart du premier axe transversal.
For this purpose, the subject of the invention is a bogie of the aforementioned type, in which each primary suspension member comprises:
  • an arm articulated about a first transverse axis on the chassis, and about a second transverse axis on the associated axle, and
  • an elastic member interposed between the arm and the frame away from the first transverse axis.

Le véhicule ferroviaire 1 représenté sur la figure 1 est, par exemple, un tramway. Le véhicule ferroviaire 1 comprend une caisse 2 et au moins un bogie 4.The railway vehicle 1 represented on the figure 1 is, for example, a tramway. The railway vehicle 1 comprises a box 2 and at least one bogie 4.

La caisse 2 est allongée suivant une direction principale A. La direction principale A s'étend selon la direction longitudinale X.The body 2 is elongated in a main direction A. The main direction A extends in the longitudinal direction X.

La caisse 2 est pourvue d'un châssis de caisse 6. Le châssis de caisse 6 est disposé au-dessus du bogie 4 et est articulé par rapport au bogie 4. Dans la position de repos du bogie 4, telle que représentée sur la figure 1, le bogie 4 est centré par rapport au châssis de caisse 6, c'est-à-dire que le plan médian P'm du châssis de caisse 6 et le plan médian Pm du bogie 4 sont confondus.The body 2 is provided with a body frame 6. The body frame 6 is disposed above the bogie 4 and is hinged relative to the bogie 4. In the rest position of the bogie 4, as shown in FIG. figure 1 , the bogie 4 is centered relative to the body frame 6, that is to say that the median plane P'm of the body frame 6 and the median plane Pm of the bogie 4 are merged.

Le châssis de caisse 6 comporte une première partie surélevée 8 située d'un premier côté 10 du plan médian P'm du châssis de caisse 6, une deuxième partie surélevée 12 située d'un deuxième coté 14 du plan médian P'm du châssis de caisse 6, et une partie basse 16 située entre la première partie surélevée 8 et la deuxième partie surélevée 12.The body frame 6 has a first elevated portion 8 located on a first side 10 of the median plane P'm of the body frame 6, a second raised portion 12 located on a second side 14 of the median plane P'm of the frame 6, and a lower portion 16 between the first raised portion 8 and the second raised portion 12.

La première partie surélevée 8 est plus large que la deuxième partie surélevée 12.The first raised portion 8 is wider than the second raised portion 12.

La partie basse 16 forme un couloir de circulation 18 parallèle à la direction principale A. Le couloir de circulation 18 est décalé transversalement vers le deuxième côté 14 par rapport au plan longitudinal médian P'm du châssis de caisse 6.The lower part 16 forms a circulation lane 18 parallel to the main direction A. The circulation lane 18 is shifted transversely towards the second side 14 with respect to the median longitudinal plane P'm of the body frame 6.

La caisse 2 définit un espace intérieur 20 d'accueil des passagers délimité vers le bas par le châssis de caisse 6.The body 2 defines a passenger interior space 20 delimited downwards by the body frame 6.

En outre, la caisse 2 comprend dans l'espace intérieur 20 une pluralité de sièges 22 fixés au châssis de caisse 6.In addition, the body 2 comprises in the interior space 20 a plurality of seats 22 fixed to the body frame 6.

Les sièges 22 sont, par exemple, agencés en plusieurs rangées 24. Chaque rangée 24 s'étend selon une direction transversale B s'étendant perpendiculairement à la direction principale A. Par exemple, les sièges 22 sont orientés de telle sorte que les passagers assis sur les sièges 22 regardent selon la direction principale A.The seats 22 are, for example, arranged in several rows 24. Each row 24 extends in a transverse direction B extending perpendicular to the main direction A. For example, the seats 22 are oriented so that the passengers sitting on seats 22 look on main direction A.

Tel que représenté sur la figure 1, une rangée 24 comprend deux sièges 22 au-dessus de la première partie surélevée 8 et un siège 22 au-dessus de la deuxième partie surélevée 12. Avantageusement, la rangée 24 ne comporte pas de siège 22 au niveau de la partie basse 16 de sorte à laisser le couloir de circulation 18 dégagé.As shown on the figure 1 a row 24 comprises two seats 22 above the first raised portion 8 and a seat 22 above the second raised portion 12. Advantageously, the row 24 has no seat 22 at the lower part 16 of so as to leave the circulation corridor 18 cleared.

Dans un exemple, la largeur de la caisse 2 est, par exemple, supérieure ou égale à 2400 mm et inférieur à 2650 mm et la largeur du couloir de circulation 18 est d'environ 720 mm.In one example, the width of the body 2 is, for example, greater than or equal to 2400 mm and less than 2650 mm and the width of the circulation lane 18 is about 720 mm.

Le bogie 4 est lié à la caisse 2 et est disposé sous le châssis de caisse 6. Le bogie 4 est propre à supporter la caisse 2 et à guider le véhicule ferroviaire 1 lors du déplacement du véhicule ferroviaire 1 le long d'un rail.The bogie 4 is linked to the body 2 and is disposed under the body frame 6. The bogie 4 is adapted to support the body 2 and guide the railway vehicle 1 when moving the rail vehicle 1 along a rail.

Le bogie 4 comprend, en outre, un réducteur avant 48 d'accouplement de l'essieu avant 36 au moteur 34 et un réducteur arrière 50 d'accouplement de l'essieu arrière 38 au moteur 34. Le bogie 4 comprend, en outre, au moins deux dispositif de suspension secondaire 52, 53 dudit bogie 4 par rapport à la caisse 2.The bogie 4 further comprises a forward coupling gearbox 36 from the front axle 36 to the engine 34 and a rear coupling gear 50 from the rear axle 38 to the engine 34. The bogie 4 further comprises at least two secondary suspension device 52, 53 of said bogie 4 relative to the body 2.

Le châssis 24 présente un premier côté 54 et un deuxième côté 56 opposé au premier côté 54, le premier côté 54 et le deuxième côté 56 étant séparés l'un de l'autre par le plan longitudinal médian Pm du châssis 24. Le plan longitudinal médian Pm est équidistant des deux roues avant 26, 30 et équidistant des deux roues arrière 28, 32.The frame 24 has a first side 54 and a second side 56 opposite the first side 54, the first side 54 and the second side 56 being separated from each other by the median longitudinal plane Pm of the frame 24.

The cross member 60 connects the two side members 58 to one another. 'other.

Dans l'exemple représenté sur les figures 2 et 3, la traverse transversale 60 est située à mi-distance des roues avant 26, 30 et des roues arrière 28, 32 du bogie 4. Cette traverse transversale 60 est une traverse centrale. La traverse transversale 60 est surbaissée de façon à permettre le passage du couloir central 18.In the example shown on the figures 2 and 3 , transverse cross member 60 is located midway from the front wheels 26, 30 and rear wheels 28, 32 of the bogie 4. This cross member 60 is a central cross member. The transverse cross member 60 is lowered so as to allow the passage of the central corridor 18.

La première roue avant 26 et la première roue arrière 28 sont situées du premier côté 54 du bogie 4. La première roue avant 26 et la première roue arrière 28 s'étendent sensiblement dans un premier plan longitudinal P1 commun.The first front wheel 26 and the first rear wheel 28 are located on the first side 54 of the bogie 4. The first front wheel 26 and the first rear wheel 28 extend substantially in a first common longitudinal plane P1.

Ici et dans la suite, lorsque l'on fait référence à des éléments « s'étendant dans un plan », on comprend que ledit plan constitue un plan médian desdits éléments. Lorsque des éléments s'étendent « sensiblement » dans un plan, on comprend que ces éléments comprennent un plan médian sensiblement parallèle audit plan, la distance du centre de l'élément au plan étant inférieure à environ 5mm.Here and in the following, when referring to elements "extending in a plane", it is understood that said plane constitutes a median plane of said elements. When elements extend "substantially" in a plane, it is understood that these elements comprise a median plane substantially parallel to said plane, the distance from the center of the element to the plane being less than about 5mm.

De même les roues arrière 28, 32 sont coaxiales, espacées transversalement l'une de l'autre. Les roues avant 26, 30 sont espacées longitudinalement des roues arrière 28, 32.The first front wheel 26 and the second front wheel 30 are coaxial, spaced transversely from each other. Similarly, the rear wheels 28, 32 are coaxial, spaced transversely from one another. The front wheels 26, 30 are spaced longitudinally from the rear wheels 28, 32.

Un plan de roulement Pr est défini par le centre de quatre roues 26, 28, 30, 32.A running surface Pr is defined by the center of four wheels 26, 28, 30, 32.

Le châssis 24 présente un plan médian longitudinal sensiblement horizontal et parallèle au plan de roulement Pr par exemple.The frame 24 has a substantially horizontal median longitudinal plane parallel to the running plane Pr for example.

Le moteur 34 est disposé du premier côté 54 du bogie 4 et est fixé au châssis 24. Le moteur 34 est solidaire du longeron 58 situé du premier côté 54. En outre, le moteur 34 est avantageusement logé dans une coque 61 servant de pièce structurelle au châssis 24.The motor 34 is disposed on the first side 54 of the bogie 4 and is fixed to the frame 24. The motor 34 is integral with the spar 58 located on the first side 54. In addition, the motor 34 is advantageously housed in a shell 61 serving as a structural part to the chassis 24.

Le moteur 34 s'étend suivant un axe longitudinal C entre la première roue avant 26 et la première roue arrière 28.The motor 34 extends along a longitudinal axis C between the first front wheel 26 and the first rear wheel 28.

Le moteur 34 est équidistant de l'essieu avant 36 et de l'essieu arrière 38.The motor 34 is equidistant from the front axle 36 and the rear axle 38.

Par exemple, l'axe longitudinal C du moteur 34 est plus proche du premier plan longitudinal P1 que du plan médian Pm.For example, the longitudinal axis C of the motor 34 is closer to the first longitudinal plane P1 than the median plane Pm.

Chaque essieu 36, 38 comprend une barre d'essieu 62. Cette barre d'essieu 62 raccorde entre elles les deux roues 26, 28, 30, 32 associées à l'essieu 36, 38.Each axle 36, 38 comprises an axle bar 62. This axle bar 62 interconnects the two wheels 26, 28, 30, 32 associated with the axle 36, 38.

Chaque barre d'essieu 62 s'étend transversalement par rapport au châssis 24. Avantageusement, les barres d'essieux 62 avant et arrière s'étendent dans un plan sensiblement parallèle à un plan transversal médian (non représenté) de la traverse centrale 60.Each axle bar 62 extends transversely relative to the frame 24. Advantageously, the front and rear axle bars 62 extend in a plane substantially parallel to a median transverse plane (not shown) of the central cross member 60.

Chacun des essieux avant 36 et arrière 38 est monté rotatif par rapport au châssis 24 par l'intermédiaire d'au moins une boîte d'essieu 64, 66. Dans l'exemple représenté, ces boites d'essieu 64, 66 sont au nombre de deux par essieu 36, 38 et comprennent, pour chaque essieu 36, 38, une première boîte d'essieu 64 du premier côté 54 et une deuxième boite d'essieu 66 du deuxième côté 56.Each of the front and rear axles 36 and 38 is rotatably mounted relative to the chassis 24 via at least one axle box 64, 66. In the example shown, these axle boxes 64, 66 are in number. two axles 36, 38 and comprise, for each axle 36, 38, a first axle box 64 of the first side 54 and a second axle box 66 of the second side 56.

Chaque boite d'essieu 64, 66 comprend au moins un palier 63, tel qu'un roulement à billes. Chaque première boîte d'essieu 64 comprend en outre un boitier 65 dans lequel est logé le ou chaque palier 63.Each axle box 64, 66 comprises at least one bearing 63, such as a ball bearing.

Dans l'exemple représenté, le réducteur avant 48 et le réducteur arrière 50 sont alignés longitudinalement, le moteur 34 étant placé longitudinalement entre le réducteur avant 48 et le réducteur arrière 50. Le réducteur avant 48 est en particulier situé du premier côté 54 dans la continuité du moteur 34, et le réducteur arrière 50 est situé du premier côté 54 dans la continuité du moteur 34.With reference to the Figure 3 , the front and rear gearboxes 50 are mounted on the frame 24 of the bogie 4 and are independent of the body 2. In the example shown, the front gearbox 48 and the rear gearbox 50 are aligned longitudinally, the motor 34 being placed longitudinally between the front gearbox 48 and the rear gearbox 50. The front gearbox 48 is in particular located on the first side 54 in the continuity of the motor 34, and the rear gearbox 50 is located on the first side 54 in the continuity of the motor 34.

Le réducteur avant 48 transmet le couple du moteur 34 à l'essieu avant 36, ceci entrainant la première roue avant 26 et la deuxième roue avant 28. De même, le réducteur arrière 50 transmet le couple du moteur 34 à l'essieu arrière 38 ceci entraînant les deux roues arrière 28, 32.The forward gearbox 48 transmits the torque from the motor 34 to the front axle 36, this driving the first front wheel 26 and the second front wheel 28. Similarly, the rear gear 50 transmits the torque from the motor 34 to the rear axle 38 this driving the two rear wheels 28, 32.

En variante, ledit axe longitudinal C s'étend uniquement sensiblement dans le plan P3 du réducteur avant 48, l'axe C étant alors typiquement à l'extérieur du plan P4 du réducteur arrière 50, ou uniquement sensiblement dans le plan P4 du réducteur arrière 50, l'axe C à l'extérieur du plan P3 du réducteur avant 48. En variante encore, l'axe longitudinal C du moteur 34 s'étend à l'extérieur des plans P3 et P4.In the example shown, the longitudinal axis C of the motor 34 extends substantially in said planes P3 and P4. In a variant, said longitudinal axis C extends only substantially in the plane P3 of the front gearbox 48, the axis C then being typically outside the plane P4 of the rear gearbox 50, or only substantially in the plane P4 of the rear gearbox 50, the axis C outside the plane P3 of the front gearbox 48. In another variant, the longitudinal axis C of the motor 34 extends outside the planes P3 and P4.

Il est également équidistant des axes de rotation respectifs de la deuxième roue avant 30 et de la deuxième roue arrière 32. Il est, en outre, sensiblement confondu avec le plan transversal médian de la traverse centrale 60.The front 48 and rear 50 reduction gears are advantageously symmetrical with respect to each other with respect to a median transverse plane P5 of the front wheels 26, 28 and rear wheels 30, 32. This median transverse plane P5 is equidistant from the axes of respective rotation of the first front wheel 26 and the first rear wheel 28. It is also equidistant from the respective axes of rotation of the second front wheel 30 and the second rear wheel 32. It is, moreover, substantially coincident with the plane transverse median of the central traverse 60.
