Description

La présente invention concerne un bogie moteur pour véhicule ferroviaire, ainsi qu'un véhicule ferroviaire pourvu d'au moins un tel bogie.The present invention relates to a motor bogie for railway vehicle, as well as a railway vehicle provided at least one such bogie.

De manière habituelle, un bogie moteur comprend des essieux prenant appui sur les rails de la voie et supportant un châssis, avec interposition d'une suspension dite primaire. La caisse du véhicule ferroviaire repose sur le châssis de ce bogie, avec interposition d'une suspension dite secondaire.Usually, a motor bogie includes axles supported on the track rails and supporting a chassis, with the interposition of a so-called primary suspension. The body of the rail vehicle rests on the chassis of this bogie, with the interposition of a so-called secondary suspension.

Chaque bogie moteur est pourvu de moyens d'entraínement de chaque essieu, qui comprennent au moins un moteur et au moins un réducteur muni d'une roue d'entraínement de l'essieu correspondant. Il est en outre prévu des moyens de support des moteurs et des réducteurs par le véhicule ferroviaire.Each motor bogie is provided with drive means of each axle, which include at least one motor and at least minus a reduction gear fitted with an axle drive wheel corresponding. Means are also provided for supporting the motors and reducers by the rail vehicle.

Il est avantageux de faire supporter la masse des moyens d'entraínement par un organe mécanique du véhicule, qui soit disposé le plus suspendu possible. Ceci contribue à réduire les efforts exercés sur les rails par le bogie moteur et permet d'augmenter la vitesse du véhicule ferroviaire. Dans cette optique, il est préférable de faire supporter les masses des moteurs et des réducteurs par l'intermédiaire de la caisse du véhicule et, à défaut, par l'intermédiaire du châssis du bogie, la solution consistant à faire supporter ces masses par les essieux étant la plus défavorable.It is advantageous to support the mass of resources drive by a mechanical organ of the vehicle, which is arranged as suspended as possible. This helps reduce the forces exerted on the rails by the motor bogie and increases the speed of the rail vehicle. In this optic, it's better to support the masses motors and reducers through the body of the vehicle and, failing that, through the chassis of the bogie, the solution consisting in making these masses support by the axles being the most unfavorable.

Par ailleurs, la caisse du véhicule, le châssis du bogie et les essieux sont libres de se déplacer les uns par rapport aux autres. Or, la roue d'entraínement du réducteur devant être solidaire de l'essieu, plus le moteur et le réducteur sont suspendus à des organes élevés, plus complexe est la transmission entre le moteur suspendu et cette roue d'entraínement fixée sur l'essieu.In addition, the vehicle body, the bogie chassis and the axles are free to move relative to each other to others. However, the drive wheel of the reducer in front be integral with the axle, plus the motor and the reduction gear are suspended from high organs, the more complex the transmission between the suspended motor and this drive wheel attached to the axle.

Il convient donc d'opérer un compromis entre une suspension de ces masses uniquement par l'essieu, simple à mettre en oeuvre mais n'autorisant que de faibles vitesses, et une suspension des masses par la caisse, permettant des vitesses élevées mais complexe en termes technologiques.It is therefore necessary to make a compromise between a suspension of these masses only by the axle, simple to implement but allowing only low speeds, and a suspension of the masses by the body, allowing high speeds but complex in technological terms.

Une première solution consiste à suspendre, à la caisse du véhicule, un ensemble moto-réducteur et à installer sur l'essieu un réducteur supplémentaire, ces deux réducteurs étant liés par l'intermédiaire d'un joint homocinétique. Cette solution présente cependant des inconvénients, en ce sens qu'il est nécessaire de faire appel à deux réducteurs séparés. De plus, l'emploi d'un joint homocinétique, particulièrement onéreux, est à l'origine de coûts importants.A first solution is to suspend, at the cash register of the vehicle, a motor-reduction unit and to be installed on the axle an additional reducer, these two reducers being linked by means of a constant velocity joint. This solution, however, has drawbacks in this sense that it is necessary to use two separate reducers. In addition, the use of a constant velocity joint, particularly expensive, is the source of significant costs.

Une solution alternative a été proposée. Elle consiste à suspendre le réducteur sur le châssis du bogie, à son extrémité opposée à l'essieu. Par ailleurs, le moteur est fixé à demeure sur le châssis, le réducteur et le moteur coopérant habituellement par l'intermédiaire d'un accouplement à dentures bombées.An alternative solution has been proposed. It consists to hang the reducer on the bogie chassis, at its end opposite the axle. Furthermore, the motor is fixed permanently on the chassis, the gear unit and the cooperating motor usually through a coupling to domed teeth.

Cet agencement, bien qu'il soit relativement avantageux en termes de coûts, présente d'autres inconvénients. En effet, les masses du moteur et du réducteur sont supportées non pas par la caisse du véhicule mais par le châssis du bogie, de sorte que les essieux exercent des efforts relativement importants sur les rails. De plus, fixer le moteur à demeure sur le châssis induit l'apparition d'efforts mécaniques élevés s'exerçant sur ce dernier.This arrangement, although it is relatively advantageous in terms of costs, has other disadvantages. Indeed, the masses of the motor and the gear unit are supported not by the vehicle body but by the bogie chassis, so that the axles exert relatively large forces on rails. In addition, fix the motor permanently on the chassis induces the appearance of high mechanical forces exercising on the latter.

Afin de pallier les différents inconvénients de l'art antérieur évoqués ci-dessus, l'invention se propose de réaliser un bogie moteur de véhicule ferroviaire, dans lequel les masses des moteurs et des réducteurs sont supportées, dans une large mesure, par la caisse du véhicule, par l'intermédiaire d'un nombre restreint d'éléments mécaniques possédant une structure simple et des coûts peu élevés.In order to overcome the various drawbacks of art mentioned above, the invention proposes to realize a motor bogie for a rail vehicle, in which the masses of the motors and the reducers are supported, in to a large extent, through the vehicle body, through a limited number of mechanical elements having simple structure and low costs.

Ce dernier est muni de plusieurs bogies, dont un seul 4 est illustré sur cette figure. Ce bogie comporte deux essieux 6, prenant appui sur des rails 8 et supportant un châssis 10, avec interposition d'une suspension primaire désignée par les références 12.

The railway vehicle is also provided with a box 14, partially shown, resting on the chassis 10 of the bogie 4, with interposition a secondary suspension 16.

Chaque essieu 6 est équipé d'un ensemble d'entraínement correspondant. Seul l'ensemble d'entraínement de l'essieu de la gauche, sur la figure 1, sera décrit dans ce qui suit, étant entendu que les deux ensembles d'entraínement sont symétriques par rapport à un axe transversal médian du bogie. Chaque ensemble d'entraínement comprend un réducteur, désigné dans son ensemble par la référence 18, qui est équipé de trois roues dentées 20, 22, 24 illustrées aux figures 3 et 4. La roue 20, solidaire de l'essieu, est une roue d'entraínement de ce dernier, alors que la roue 24 est une roue motrice entraínée par un moteur, comme cela sera explicité dans ce qui suit, la roue 22 étant une roue intermédiaire.Each axle 6 is equipped with a drive assembly corresponding. Only the axle drive assembly of the left, in FIG. 1, will be described in the following, it being understood that the two drive assemblies are symmetrical about a median transverse axis of the bogie. Each drive assembly includes a gearbox, designated as a whole by reference 18, which is equipped with three toothed wheels 20, 22, 24 illustrated in FIGS. 3 and 4. The wheel 20, integral with the axle, is a drive wheel of the latter, while the wheel 24 is a driving wheel driven by a motor, as will be explained in what follows, the wheel 22 being an intermediate wheel.

Ces roues 20, 22, 24, qui sont disposées les unes derrière les autres dans la direction d'avancée F du véhicule ferroviaire, sont logées dans un carter 26 qui est formé de deux demi-éléments, de façon classique. Le carter 26 tourillonne sur l'axe de l'essieu 6, la roue d'entraínement 20 est solidaire de l'essieu alors que les deux autres roues 22 et 24 sont portées par le carter. Les trois axes des roues 20, 22, 24 sont disposés dans un plan incliné faiblement par rapport à l'horizontale, mais peuvent être disposés de manière différente en fonction de l'agencement du bogie.These wheels 20, 22, 24, which are arranged one behind the others in the forward direction F of the vehicle rail, are housed in a casing 26 which is formed of two half elements, conventionally. Housing 26 journals on the axis of the axle 6, the drive wheel 20 is secured to the axle while the other two wheels 22 and 24 are carried by the casing.

Le carter 26 est pourvu d'une saillie 28 s'étendant transversalement, disposée vers l'extrémité arrière de ce carter 26 opposée à l'essieu 6. Une bielle 30 s'étendant sensiblement verticalement, est monté à rotule d'une part sur la saillie 28 du carter 26 et d'autre part dans une chape 32 dont est pourvue une traverse 34 de la caisse 14 (figure 4). Cette bielle est représentée seulement partiellement sur la figure 2.The casing 26 is provided with a projection 28 extending transversely, disposed towards the rear end of this casing 26 opposite the axle 6. A connecting rod 30 extending substantially vertically, is mounted on a ball on the one hand on the projection 28 of the casing 26 and on the other hand in a yoke 32 which is provided with a cross member 34 of the body 14 (Figure 4). This connecting rod is shown only partially on the figure 2.

Chaque ensemble d'entraínement comprend également un moteur, désigné dans son ensemble par la référence 36. Ce dernier, qui est alimenté par des moyens électriques non représentés, est reçu dans un logement 38 sensiblement parallélépipédique. Ce moteur, qui est décalé transversalement par rapport au réducteur 18, se trouve en regard de l'extrémité de ce réducteur opposée à l'essieu 6. Dans un but de clarté, le moteur n'est par représenté sur la figure 2 et a été représenté en traits mixtes sur la figure 3.Each training set also includes a engine, designated as a whole by the reference 36. This last one which is powered by electrical means not shown, is received in a housing 38 substantially parallelepiped.

In order to clarity, the engine is not shown in Figure 2 and has has been shown in phantom in Figure 3.

Le logement 38 est articulé, autour d'un axe horizontal, à une traverse 40 du châssis 10 du bogie 4. A cet effet, le logement 38 est solidaire de deux bras 42, 44 articulés à des chapes 46 dont est pourvue la traverse 40. Le premier bras 42 s'étend de façon longitudinale alors que l'autre bras 44 s'étend de manière oblique, étant entendu que les bras 42, 44 peuvent être parallèles.The housing 38 is articulated around a horizontal axis, to a crosspiece 40 of the chassis 10 of the bogie 4. For this purpose, the housing 38 is secured to two arms 42, 44 articulated to yokes 46 with which the crosspiece 40 is provided. The first arm 42 extends longitudinally while the other arm 44 extends obliquely, it being understood that the arms 42, 44 can be parallel.

Le mouvement de rotation du moteur est transmis à la roue motrice 24 par l'intermédiaire d'un accouplement 48 à dentures bombées, de type classique.The rotational movement of the motor is transmitted to the wheel drive 24 via a coupling 48 with teeth curved, classic type.

Le carter 26 est pourvu, à son extrémité opposée à l'essieu 6, d'une bride 50 faisant saillie à la fois vers le haut et en direction du moteur. Ce dernier est muni, à sa partie inférieure, d'un nez 52, qui fait saillie en direction du réducteur et se trouve à l'aplomb de la bride 50. La bride 50 et le nez 52 sont disposés de part et d'autre de la roue motrice 24. Une biellette de liaison 54 est montée à rotule, par ses deux extrémités, respectivement sur la bride 50 et sur le nez 52. Elle présente, vue de côté, une forme de C et s'étend au voisinage de l'accouplement 48, à l'opposé de celui-ci par rapport à l'essieu 6. Cette biellette permet l'articulation du moteur au réducteur. De façon avantageuse, la bride 50 et le nez 52 sont disposés de manière à être alignés avec l'axe de la roue motrice 24, un léger écart d'alignement étant cependant acceptable.The casing 26 is provided, at its end opposite to axle 6, with a flange 50 projecting both towards the up and towards the engine. The latter is provided, at his lower part, of a nose 52, which projects in the direction of the reducer and is directly above the flange 50. The flange 50 and the nose 52 are arranged on either side of the wheel drive 24. A connecting rod 54 is mounted with ball joint, by its two ends, respectively on the flange 50 and on the nose 52. It has a side view of a C shape and extends in the vicinity of the coupling 48, opposite to this with respect to the axle 6. This link allows the articulation of the motor to the reduction gear. Advantageously, the flange 50 and the nose 52 are arranged so as to be aligned with the axis of the drive wheel 24, a slight deviation alignment is however acceptable.

Comme le montre la figure 2, le châssis 10 du bogie 4 est pourvu, à l'opposé de l'essieu 6 par rapport au moteur 36, c'est-à-dire à son extrémité avant, d'une traverse tubulaire 56 équipée d'une timonerie non représentée de freins à disque. Cette timonerie est propre à coopérer avec des disques 58 solidaire de l'essieu 6, visibles sur la figure 4.As shown in Figure 2, the chassis 10 of the bogie 4 is provided, opposite the axle 6 with respect to the motor 36, that is to say at its front end, a tubular cross member 56 fitted with a wheelhouse not shown with disc brakes. This wheelhouse is suitable for cooperating with discs 58 integral with axle 6, visible in FIG. 4.

En se référant à nouveau à la figure 1, le centre de gravité g du réducteur et le centre de gravité g' du moteur 36 sont disposés, vus de côté, de part et d'autre de la saillie 28, qui constitue le point d'articulation du réducteur 18 à la bielle 30, et donc à la caisse 14. Par ailleurs, le moment exercé par le réducteur sur cette saillie 28 est sensiblement égal au moment exercé par le moteur 36 sur cette même saillie. En d'autres termes, le produit de la masse m du réducteur par la distance d séparant le centre de gravité g et la saillie 28 vus de côté, est sensiblement égal au produit de la masse M du moteur par la distance d' séparant, vue de côté, la saillie 28 et le point d'articulation du moteur au réducteur, à savoir la bride 50.Referring again to FIG. 1, the center of gravity g of the reduction gear and the center of gravity g 'of the motor 36 are arranged, seen from the side, on either side of the projection 28, which constitutes the point d 'articulation of the reducer 18 to the connecting rod 30, and therefore to the body 14. Furthermore, the moment exerted by the reducer on this projection 28 is substantially equal to the moment exerted by the motor 36 on this same projection. In other words, the product of the mass m of the reducer by the distance d separating the center of gravity g and the projection 28 seen from the side, is substantially equal to the product of the mass M of the motor by the distance of separating, side view, the projection 28 and the point of articulation of the motor to the reduction gear, namely the flange 50.

Comme le montre en outre la figure 4, les centres de gravité g, g' sont disposés, vus de dessus, de part et d'autre de la saillie 28, de sorte que cette dernière est disposée à peu près au barycentre du système formé par le moteur et le réducteur.As further shown in Figure 4, the centers of gravity g , g 'are arranged, seen from above, on either side of the projection 28, so that the latter is disposed approximately at the barycenter of the system formed by the motor and the reducer.

En service, les déplacements relatifs en transversal et en courbe, de la caisse par rapport à l'essieu sont compensés par l'intermédiaire de la bielle de suspension 30, qui est monté rotulante à ses deux extrémités. Les déplacements relatifs de l'essieu par rapport au châssis du bogie sont compensés d'une part par l'intermédiaire des bras 42, 44, qui possèdent un léger débattement transversal, et d'autre part grâce à la biellette de liaison 54, qui est montée rotulante à ses deux extrémités. Le réducteur 18 est lié en translation à l'essieu 6 qui le reçoit.In service, relative displacements in transverse and in curve, of the body with respect to the axle are compensated via the suspension rod 30, which is swivel mounted at both ends. Displacements axle relative to the bogie chassis are compensated on the one hand by means of the arms 42, 44, which have a slight transverse clearance, and on the other hand thanks to the connecting rod 54, which is pivotally mounted at both ends. The reduction gear 18 is linked in translation to axle 6 which receives it.

La figure 5 représente une variante de l'invention, dans laquelle le carter 26 possède un plan de joint P s'étendant de façon oblique, de manière à définir deux éléments de carter 26', 26''. Le premier élément 26' s'étend uniquement au voisinage de l'essieu 6 et de la roue 20, alors que le deuxième élément 26'', suspendu par la bielle 30, recouvre les roues 22 et 24. De la sorte, il est possible d'ôter le premier élément 26', de façon à démonter l'essieu et sa roue 20, sans interagir sur les roues 22 et 24, qui restent suspendues par la bielle 30.FIG. 5 represents a variant of the invention, in which the casing 26 has a joint plane P extending obliquely, so as to define two housing elements 26 ', 26' '. The first element 26 'extends only to the vicinity of axle 6 and wheel 20, while the second element 26 '', suspended by the rod 30, covers the wheels 22 and 24. In this way, it is possible to remove the first element 26 ', so as to disassemble the axle and its wheel 20, without interact on wheels 22 and 24, which remain suspended by the connecting rod 30.

Dans les modes de réalisation décrits ci-dessus, le réducteur 18 est suspendu à la caisse du véhicule, le moteur étant articulé d'une part au châssis du bogie et d'autre part au réducteur. Il est également envisageable de suspendre le moteur à la caisse, par l'intermédiaire d'une bielle analogue à celle 30 représentée. Le moteur est, dans ce cas, également articulé au châssis du bogie et le réducteurest uniquement suspendu au moteur, sans être suspendu directement à la caisse.In the embodiments described above, the reducer 18 is suspended from the vehicle body, the engine being articulated on the one hand to the chassis of the bogie and on the other hand to the reducer. It is also possible to suspend the engine at the body, via a similar rod to that 30 shown. The motor is, in this case, also articulated to the bogie chassis and the reduction gear is only suspended from the engine, without being directly suspended from the checkout.

L'invention permet de réaliser les objectifs précédemment mentionnés. Elle permet en effet de suspendre verticalement à la caisse une partie importante des masses du moteur et du réducteur. Il convient à cet égard de noter que, bien que le réducteur et le moteur soient liés respectivement à l'essieu et au châssis du bogie, ils n'exercent que de faibles contraintes sur ces éléments.The invention makes it possible to achieve the objectives previously mentioned. It allows you to hang vertically at the body a significant part of the engine and reducer. In this regard, it should be noted that, although the gearbox and motor are linked to the axle respectively and on the bogie chassis, they exert only weak constraints on these elements.

Par ailleurs, l'invention fait intervenir un très faible nombre d'éléments mécaniques, puisqu'une unique bielle permet la suspension du réducteur à la caisse, alors qu'une autre unique biellette assure l'articulation mutuelle du moteur et du réducteur. Ces éléments mécaniques sont robustes, de conception simple et de coûts réduits.Furthermore, the invention involves a very low number of mechanical elements, since a single connecting rod allows the suspension of the reducer at the body, while another single link ensures the mutual articulation of the engine and of the reducer. These mechanical elements are robust, simple design and reduced costs.

L'agencement conforme à l'invention génère peu de mouvements transversaux entre le réducteur et le moteur. Ceci garantit un fonctionnement optimal de l'accouplement permettant la transmission entre ce moteur et ce réducteur et permet de réduire la masse de ces derniers. Etant donné que le réducteur est décalé longitudinalement par rapport à l'essieu, il est possible de placer des disques de freinage sur cet essieu, au sein de l'espace ainsi libéré.The arrangement according to the invention generates little transverse movements between the reducer and the motor. This guarantees an optimal functioning of the coupling allowing the transmission between this motor and this reducer and allows to reduce the mass of these. Since the reduction gear is offset longitudinally with respect to the axle, it is possible to place brake discs on this axle, within the space thus freed.

Disposer les centres de gravités respectivement du moteur et du réducteur de part et d'autre, en vue de côté (figures 1 et 3), du point d'articulation de la bielle de suspension du réducteur, ou du moteur, à la caisse est avantageux. Une telle conformation permet en effet aux moments exercés sur ce point d'articulation à la fois par le moteur et le réducteur de se compenser. Dans cette optique, il est particulièrement avantageux que ces moments s'annulent, lorsque les produits des masses respectivement du réducteur et du moteur, par la longueur des bras de levier correspondants sont égaux.Arrange the centers of gravity respectively of the engine and the reducer on both sides, in side view (figures 1 and 3), from the point of articulation of the suspension rod gearbox, or motor, to the body is advantageous. A such conformation indeed allows the moments exerted on this point of articulation by both the motor and the gearbox to compensate. With this in mind, it is particularly advantageous that these moments cancel each other out, when the products masses respectively of the reducer and the motor, by the length of the corresponding lever arms are equal.

Le fait que le centre de gravité du réducteur et du moteur soient disposés, en vue de dessus (figure 4), de part et d'autre du point d'articulation de la bielle de suspension au réducteur, ou au moteur, est également avantageux. Ceci confère une excellente stabilité à l'ensemble formé par ce moteur et ce réducteur, dans la mesure où ce point d'articulation est situé à peu près au barycentre de cet ensemble.The fact that the center of gravity of the reducer and engine are arranged, in top view (Figure 4), from and other from the point of articulation of the suspension rod to the reduction gear, or to the motor, is also advantageous. This gives excellent stability to the assembly formed by this motor and this reducer, insofar as this point of articulation is located approximately at the barycenter of this set.
