Definitions
- the present invention relates to a railway vehicle axle of the type comprising a central shaft, two wheels connected in rotation by the shaft and two bearings, each wheel being rotatably mounted relative to a bearing along the axis of the wheels, a bogie comprising a such axle, and a railway vehicle comprising such a bogie.
- Such axles are conventionally used for rail vehicles, particularly for urban rail transport, of the tramway type. These conventional axles equip bogies supporting vehicle bodies whose floor is, generally, above the axles, at a height of 520 mm above the upper edge of the rails with standard wheels 590 mm in diameter at the new condition. In urban areas, and therefore without a platform, this floor height represents a difficulty for passenger access, for example, in a tramway.
- the document WO 0 / 64,721 describes a railway vehicle with, on the one hand, a lowered floor above the axles of a height, above the upper edge of the rails, of 450 mm thanks to wheels of diameter smaller than the standard diameter and, on the other hand, a floor area of lesser height, approximately 355 mm above the rails, connected by ramps to the floor area above the axles, this lower area being an area of easy access for passengers.
- axles bent Such axles, described for example in the document EP 911 239 , are located under the axis of rotation of the wheels, by making it possible to lower the floor at the level of the axles of the wheels, thanks to a complex arrangement of transmission of the driving torques to the wheels.
- These axles comprise in fact angular references and / or reducers allowing the implementation of a remote rotary connection shaft parallel to the axis of rotation of the wheels.
- the object of the invention is therefore to provide a lowered floor vehicle without the disadvantages mentioned above.
- the subject of the invention is an axle for a railway vehicle of the aforementioned type, characterized in that it furthermore comprises at least one bending stiffening cross member of the axle, this cross member rigidly connecting the two bearings, and that the diameter of the shaft is between 60 and 140 mm.
- the invention also relates to a bogie comprising a chassis and at least one axle as defined above supporting said bogie.
- the invention also relates to a rail vehicle comprising a body and at least one bogie as defined above for the support of the body.
- the bogie 1 of the figure 1 essentially comprises a chassis 5, two pairs of wheels 9 each integrated in an axle 11, and a suspension system 15 interposed between the axles 11 and the chassis 5.
- the chassis 5 has the general shape of H with two spars 17, parallel to the longitudinal axis X of the truck 1. Each spar 17 has two zones 18 of difference in elevation, the median part of the spar between the two axles 11 being lower than the ends of the spar.
- the two longitudinal members 17 are connected by a transverse central beam 19 perpendicular to the longitudinal members 17.
- the chassis 5 is intended to support a body 20 of a vehicle, such as a tramway.
- the body 20 is, for example, articulated in the center of the beam 19.
- Each axle 11 comprises a central shaft 21 which extends transversely along the entire width of the axle. It connects the two wheels 9 in rotation and extends along the Y axis of common rotation of the two wheels.
- Each wheel 9 is rotatably mounted relative to a bearing 22.
- a crossbar 23 visible on the figure 2 , for example cylindrical and of rectangular section, rigidly connects the two bearings 22 to each other by their lower ends, to the right of the shaft 21.
- the crossbar 23 is thus parallel to the axis Y of rotation of the wheels 9 and located under the shaft 21. it is slightly spaced from the latter by a distance l advantageously for a tram between 80 and 120 mm, for example of the order of 100 mm.
- the two bearings 22 each have a bearing surface of the suspension system 15.
- the wheels 9 have a diameter D advantageously between 530 mm and 620 mm, for example of the order of 590 mm.
- 590 mm is the diameter standard for tramway wheels, in new condition.
- the standard 9-wheel diameter can go down to 530 mm with wear.
- the wheels 9 are placed on rails 24.
- each shaft 21 is advantageously between 60 mm and 140 mm, for example of the order of 100 mm.
- the crosspiece 23 has a section at least equal to that of the shaft 21.
- Bogie control members such as a speed reducer 26 or a motor, for example, are housed in one or more bearings 22.
- the floor 31 of the body 20 of the vehicle, located just above the axle 11, is spaced from the axle 11 of an interval i.
- the interval i, corresponding to the deflection of the suspensions 15, is advantageously between 40 and 80 mm, of the order of 60 mm for example.
- the floor 31 is of a thickness e, advantageously between 30 and 70 mm, for example of the order of 50 mm.
- the beam 19 connects the longitudinal members 17 passing under the floor 31.
- the operating principle of the invention is to optimize the vertical space requirement of the axle 11 by reducing it to the maximum in height, in order to free up space to descend as far as possible to the floor 31 of the body 20 of the vehicle.
- axle 11 The traditional functions of the axle 11 are separated here. Indeed, an axle 11 must generally, firstly secure the wheels 9 and rotate them by transmitting the traction and braking torques, the wheels 9 thus rotating together and parallel, and, secondly, withstand the bending forces due to the mass of the vehicle and the chassis 5, transmitted by the suspension system 15.
- the truck 1 separates the functions of the axle 11 between, on the one hand, the central shaft 21 which fills the first function of the axle, and secondly, the cross member 23 which performs the second function.
- the crossbar 23 has in fact sufficient inertia to resist bending due to the forces from the vehicle and the chassis.
- the crossbar 23 does not rotate, and only the shaft 21 drives the wheels 9 in rotation.
- the only dimensioning constraint of the central shaft 21 is the driving function of the wheels 9 by the shaft 21, which can therefore be of smaller diameter than if it fulfilled the two functions of the axle 11.
- the invention allows a lowering of the floor 31 to the height h of 455 mm, taking into account also the thickness of the floor 31.
- an axle 11 allows a simple transmission system, the first function of the axle being retained, thanks to the central shaft 21.
- a ramp inclination of less than 10% is advantageously provided for connecting the floor 31 of the area above the bogie to a lower floor zone 39 h ' .
- This zone 39 of lower height h ' is for example the passenger access zone. This results in a relatively low floor level 39 for the passenger access area, of the order of 355 mm.
- each axle comprises two cross members, for example in the case (not shown) where the bearings are located outside the wheels.
- Each crossbar connects the two bearings, the first crossbar being located in front of the wheels and the second behind the wheels, symmetrically with respect to the shaft.
- each axle 11 is located under the corresponding shaft 21, and spaced therefrom.
- the shaft 21 is located outside the crossbar 23.
- the crossbar 23 is nevertheless located at a height lower than that of the conventional axle for the same application with respect to the tops of the rails 24. More specifically, the crossbar 23 is made with a neutral surface of the crossbar located below the axis of the tree.
- the neutral bending surface under vertical load of the beam is called the location of the points of zero longitudinal stress in flexion under a vertical load due to the chassis 5 and to a rail vehicle resting on the chassis
- the crossbar 23 has for example more material in the lower part, between the shaft 21 and the top of the rail, in the upper part, above the shaft 21.
- the crossbar 23 is offset vertically relative to the shaft 21 so that the clearance Jsup between the shaft 21 and the upper inner wall of the crossmember 23 is less than the clearance Jinf between the shaft 21 and the lower inner wall of the crossbar 23.
- the crosspiece 23 defines with the bearings 22 a sealed volume around the shaft 21, between the bearings 22.
- the distance i between the shaft 21 and the floor 31 must be sufficient to accommodate the upper wall of the cross member 23 (which is for example of the order of 10 mm), and arrange a sufficient Jsup clearance (for example of the order of 10 mm).
- the height of the floor 31 is greater than that which can be obtained with the embodiment of the figure 2 (for example greater than 20 mm).

Description
La présente invention concerne un essieu pour véhicule ferroviaire du type comprenant un arbre central, deux roues liées en rotation par l'arbre et deux paliers, chaque roue étant montée rotative par rapport à un palier suivant l'axe des roues, un bogie comprenant un tel essieu, et un véhicule ferroviaire comprenant un tel bogie.The present invention relates to a railway vehicle axle of the type comprising a central shaft, two wheels connected in rotation by the shaft and two bearings, each wheel being rotatably mounted relative to a bearing along the axis of the wheels, a bogie comprising a such axle, and a railway vehicle comprising such a bogie.
De tels essieux sont classiquement utilisés pour des véhicules ferroviaires notamment pour le transport ferroviaire urbain, de type tramway. Ces essieux classiques équipent des bogies supportant des caisses de véhicule dont le plancher est, généralement, au-dessus des essieux, à une hauteur de 520 mm au-dessus du bord supérieur des rails avec des roues standard de 590 mm de diamètre à l'état neuf. En milieu urbain, et donc sans quai, cette hauteur de plancher représente une difficulté pour l'accès des passagers, par exemple, dans un tramway.Such axles are conventionally used for rail vehicles, particularly for urban rail transport, of the tramway type. These conventional axles equip bogies supporting vehicle bodies whose floor is, generally, above the axles, at a height of 520 mm above the upper edge of the rails with standard wheels 590 mm in diameter at the new condition. In urban areas, and therefore without a platform, this floor height represents a difficulty for passenger access, for example, in a tramway.
Le document
Il existe également des essieux coudés. De tels essieux, décrits par exemple dans le document
Les inconvénients de ces deux types d'essieux sont, dans le premier cas, la nécessité d'utiliser des roues non standard et, dans le second cas, une complexité et donc un coût élevé de fabrication des essieux.The disadvantages of these two types of axles are, in the first case, the need to use non-standard wheels and, in the second case, a complexity and therefore a high cost of manufacturing the axles.
Le but de l'invention est donc de fournir un véhicule à plancher abaissé sans les inconvénients mentionnés précédemment.The object of the invention is therefore to provide a lowered floor vehicle without the disadvantages mentioned above.
A cet effet l'invention a pour objet un essieu pour véhicule ferroviaire du type précité, caractérisé en ce qu'il comprend en outre au moins une traverse de rigidification en flexion de l'essieu, cette traverse reliant rigidement les deux paliers, et en ce que le diamètre de l'arbre est compris entre 60 et 140 mm.To this end, the subject of the invention is an axle for a railway vehicle of the aforementioned type, characterized in that it furthermore comprises at least one bending stiffening cross member of the axle, this cross member rigidly connecting the two bearings, and that the diameter of the shaft is between 60 and 140 mm.
D'autres caractéristiques de l'invention figurent aux revendications 2 à 6.Other features of the invention appear in claims 2 to 6.
L'invention a également pour objet un bogie comprenant un châssis et au moins un essieu tel que défini ci-dessus supportant ledit bogie.The invention also relates to a bogie comprising a chassis and at least one axle as defined above supporting said bogie.
L'invention a également pour objet un véhicule ferroviaire comprenant une caisse et au moins un bogie tel que défini ci-dessus pour le support de la caisse.The invention also relates to a rail vehicle comprising a body and at least one bogie as defined above for the support of the body.
Suivant d'autres caractéristiques de l'invention, dans le cas par exemple d'un tramway :
- les roues ont un diamètre compris entre 530 et 660 mm, et le véhicule comprend un premier plancher d'une hauteur comprise entre 385 et 510 mm au-dessus du bord supérieur des rails dans la région du bogie ; et
- le véhicule ferroviaire comprend un second plancher d'une hauteur comprise entre 335 et 375 mm les deux planchers étant reliés par une rampe d'inclinaison comprise entre 5 et 10%.
- the wheels have a diameter of between 530 and 660 mm, and the vehicle comprises a first floor with a height between 385 and 510 mm above the upper edge of the rails in the region of the bogie; and
- the railway vehicle comprises a second floor with a height of between 335 and 375 mm, the two floors being connected by a ramp of inclination of between 5 and 10%.

Le bogie 1 de la
Le châssis 5 a une forme générale de H avec deux longerons 17, parallèles à l'axe X longitudinal du bogie 1. Chaque longeron 17 présente deux zones 18 de dénivellation, la partie médiane du longeron entre les deux essieux 11 étant plus basse que les extrémités du longeron. Les deux longerons 17 sont reliés par une poutre 19 centrale transversale perpendiculaire aux longerons 17. Le châssis 5 est destiné à supporter une caisse 20 d'un véhicule, de tramway par exemple. La caisse 20 est, par exemple, articulée au centre de la poutre 19.The
Chaque essieu 11 comprend un arbre central 21 qui s'étend transversalement suivant toute la largeur de l'essieu. Il relie les deux roues 9 en rotation et s'étend suivant l'axe Y de rotation commun des deux roues.Each

Les roues 9 ont un diamètre D avantageusement compris entre 530 mm et 620 mm, par exemple de l'ordre de 590 mm. 590 mm est le diamètre standard pour des roues de tramway, à l'état neuf. Le diamètre de roues 9 standard peut descendre jusqu'à 530 mm avec l'usure. Les roues 9 sont posées sur des rails 24.The
Le diamètre d de chaque arbre 21 est avantageusement compris entre 60 mm et 140 mm, par exemple de l'ordre de 100 mm.The diameter d of each
La traverse 23 a une section au moins égale à celle de l'arbre 21.The
Des organes de contrôle du bogie, comme un réducteur de vitesse 26 ou un moteur, par exemple, sont logés dans un ou plusieurs paliers 22.Bogie control members, such as a
Le plancher 31 de la caisse 20 du véhicule, situé juste au-dessus de l'essieu 11, est espacé de l'essieu 11 d'un intervalle i. L'intervalle i, correspondant au débattement des suspensions 15, est avantageusement compris entre 40 et 80 mm, de l'ordre de 60 mm par exemple. Le plancher 31 est d'une épaisseur e, avantageusement comprise entre 30 et 70mm, par exemple de l'ordre de 50 mm.The
Le côté intérieur du plancher 31 est ainsi à une hauteur h du sommet du rail qui est une fonction de D, d, e et i suivant la relation :
h est donc compris entre
h is therefore between
La poutre 19 relie les longerons 17 en passant sous le plancher 31.The
Le principe de fonctionnement de l'invention est d'optimiser l'encombrement vertical de l'essieu 11 en le réduisant au maximum en hauteur, afin de libérer de l'espace pour descendre au maximum le plancher 31 de la caisse 20 du véhicule.The operating principle of the invention is to optimize the vertical space requirement of the
Les fonctions traditionnelles de l'essieu 11 sont ici séparées. En effet, un essieu 11 doit généralement, d'une part solidariser les roues 9 et les entraîner en rotation en leur transmettant les couples de traction et de freinage, les roues 9 tournant ainsi ensemble et parallèlement, et, d'autre part, résister aux efforts de flexion dus à la masse du véhicule et du châssis 5, transmis par le système de suspension 15.The traditional functions of the
Le bogie 1 sépare les fonctions de l'essieu 11 entre d'une part, l'arbre central 21 qui remplit la première fonction de l'essieu, et d'autre part, la traverse 23 qui remplit la seconde fonction.The truck 1 separates the functions of the
La traverse 23 présente en effet une inertie suffisante pour résister à la flexion due aux efforts provenant du véhicule et du châssis. La traverse 23 ne tourne pas, et seul l'arbre 21 entraîne les roues 9 en rotation.The
Ainsi, la seule contrainte de dimensionnement de l'arbre central 21 est la fonction d'entraînement des roues 9 par l'arbre 21, qui peut donc être d'un diamètre plus petit que s'il remplissait les deux fonctions de l'essieu 11.Thus, the only dimensioning constraint of the
Comme la hauteur h du plancher 31 de la caisse 20 au-dessus du bord supérieur des rails 24 est limitée par le rayon R/2 des roues 9 augmenté du rayon d/2 de l'arbre 21, et d'un intervalle minimum i, l'invention permet un abaissement du plancher 31 à la hauteur h de 455 mm, en tenant compte en outre de l'épaisseur du plancher 31.As the height h of the
De plus, un essieu 11 permet un système simple de transmission, la première fonction de l'essieu étant conservée, grâce à l'arbre central 21.In addition, an
Comme le montre la
En variante, chaque essieu comprend deux traverses, par exemple dans le cas (non représenté) où les paliers sont situés à l'extérieur des roues. Chaque traverse relie les deux paliers, la première traverse étant située devant les roues et la seconde derrière les roues, symétriquement par rapport à l'arbre.Alternatively, each axle comprises two cross members, for example in the case (not shown) where the bearings are located outside the wheels. Each crossbar connects the two bearings, the first crossbar being located in front of the wheels and the second behind the wheels, symmetrically with respect to the shaft.
Dans le mode de réalisation des
Le mode de réalisation illustré sur la
La traverse 23 est néanmoins située à une hauteur inférieure à celle de l'essieu classique pour la même application par rapport aux sommets des rails 24. Plus précisément, la traverse 23 est réalisée avec une surface neutre de la traverse située en dessous de l'axe de l'arbre.The
On appelle la surface neutre en flexion sous charge verticale de la traverse le lieu des points de contrainte longitudinale nulle en flexion sous une charge verticale due au châssis 5 et à un véhicule ferroviaire en appui sur le châssisThe neutral bending surface under vertical load of the beam is called the location of the points of zero longitudinal stress in flexion under a vertical load due to the
Pour ce faire, la traverse 23 possède par exemple plus de matière en partie inférieure, entre l'arbre 21 et le sommet du rail, qu'en partie supérieure, au-dessus de l'arbre 21. Dans l'exemple illustré, la traverse 23 est décalée verticalement par rapport à l'arbre 21 de sorte que le jeu Jsup entre l'arbre 21 et la paroi interne supérieure de la traverse 23 est inférieur au jeu Jinf entre l'arbre 21 et la paroi interne inférieure de la traverse 23.To do this, the
La traverse 23 définit avec les paliers 22 un volume étanche autour de l'arbre 21, entre les paliers 22.The
Ainsi, les sorties des paliers 22 côté intérieur (du côté de chaque palier 22 opposé à la roue 9 adjacente) sont rendues étanches par la traverse 23, et il n'est pas nécessaire de prévoir des moyens d'étanchéité supplémentaires. Seules les sorties des paliers 22 côté extérieur doivent être munies de moyens d'étanchéité. Ceci présente l'avantage de simplifier les paliers 22 et de réduire le coût de fabrication de l'essieu 11.Thus, the outlets of the
Dans ce mode de réalisation, la distance i entre l'arbre 21 et le plancher 31 doit être suffisante pour loger la paroi supérieure de la traverse 23 (qui est par exemple de l'ordre de 10 mm), et ménager un jeu Jsup suffisant (par exemple de l'ordre de 10 mm). Il en résulte que la hauteur du plancher 31 est supérieure à celle que l'on peut obtenir avec le mode de réalisation de la
