Description

La présente invention se rapporte à un bogie porteur de caisse de véhicule ferroviaire, comportant un châssis monté sur des roues de diamètre standard et équipé de freins au moins un essieu fixe de forme coudée permettant le logement bas du plancher du véhicule, servant d'appui à des ressorts de suspension primaire et supportant deux fusées sur lesquelles sont montées les roues, les fusées étant situées plus haut que la partie basse des essieux fixes.The present invention relates to a bogie carrying the body of a railway vehicle, comprising a chassis mounted on wheels of standard diameter and equipped with brakes at least one fixed axle of angled shape allowing the bottom housing of the vehicle floor, serving as support to primary suspension springs and supporting two rockets on which the wheels are mounted, the rockets being located higher than the lower part of the fixed axles.

On connaît par le document FR-A-2 484 940, un bogie porteur se plaçant sous les extrémités articulées de deux caisses. Un anneau d'intercir- culation constitué de deux parties articulées est placé entre les caisses et permet le passage de l'une à l'autre caisse. Si l'on voulait surbaisser le plancher, il faudrait que les roues aient un diamètre inférieur au diamètre standard.Document FR-A-2 484 940 discloses a carrier bogie placed under the articulated ends of two boxes. An interlocking ring made up of two articulated parts is placed between the boxes and allows the passage from one to the other box. If you wanted to lower the floor, the wheels would have to be smaller than the standard diameter.

Le document FR-A-2 538 334 décrit un bogie à deux essieux pour véhicules ferroviaires, comprenant un châssis formé de deux longerons dont les extrémités supportent de façon articulée à l'aide de supports annulaires élastiques deux essieux qui portent respectivement des roues de diamètre réduit. Un tel bogie ne permet pas l'emploi de roues de diamètre standard.Document FR-A-2 538 334 describes a two-axle bogie for railway vehicles, comprising a chassis formed by two longitudinal members, the ends of which support in an articulated manner with the aid of elastic annular supports two axles which respectively carry wheels of diameter reduced. Such a bogie does not allow the use of standard diameter wheels.

Le document FR-A-1 126 807 décrit un bogie porteur correspondant au préambule de la revendication 1, et comportant un châssis monté sur des roues de diamètre standard et équipé de freins, un essieu fixe de forme coudée permettant le logement bas du plancher du véhicule, servant d'appui à des ressorts de suspension primaire et supportant deux fusées, situées plus haut que la partie basse de l'essieu fixe, et sur lesquelles sont montées les roues. Mais l'essieu a des extrémités en col de cygne qui viennent encadrer les roues. Il est donc encombrant, complique le montage et le démontage, et empêche de disposer des freins à disque de diamètre standard ou d'autres organes, tels que des capteurs de mesure de rotation, du côté externe des roues.The document FR-A-1,126,807 describes a load-bearing bogie corresponding to the preamble of claim 1, and comprising a chassis mounted on standard diameter wheels and equipped with brakes, a fixed axle of angled shape allowing the bottom housing of the floor of the vehicle, serving as a support for primary suspension springs and supporting two rockets, located higher than the lower part of the fixed axle, and on which the wheels are mounted. But the axle has swan neck ends that frame the wheels. It is therefore bulky, complicates assembly and disassembly, and prevents the use of standard diameter disc brakes or other members, such as sensors for measuring rotation, on the external side of the wheels.

On connaît aussi, par le EP-A-0 058 914 une rame de tramway articulée, à plancher surbaissé, dans laquelle le bogie porteur est placé, non pas sous l'articulation des caisses mais sous une des caisses. Les roues ont alors un diamètre inférieur au diamètre de roue standard. De ce fait l'usure est rapide.EP-A-0 058 914 also discloses an articulated tram train, with a lowered floor, in which the carrying bogie is placed, not under the articulation of the boxes but under one of the boxes. The wheels then have a diameter smaller than the standard wheel diameter. As a result, wear is rapid.

Les disques de frein ont un diamètre limité par le diamètre des roues. Le parc de pièces de rechanges est plus important et les procédures d'entretien sont différentes. Le matériel n'a pas les mêmes qualités de stabilité dans les deux sens de circulation. Les efforts sont différents de part et d'autre de l'articulation, celle-ci transmettant tous les efforts de la caisse avant.The brake discs have a diameter limited by the diameter of the wheels. The fleet of spare parts is larger and the maintenance procedures are different. The material does not have the same qualities of stability in the two directions of circulation. The efforts are different on both sides of the joint, the latter transmitting all the efforts of the front body.

La présente invention a pour but de fournir un bogie porteur, notamment pour tramway, présentant des roues de diamètre standard et permettant de ménager, directement au dessus, une partie centrale de plancher (dans les demi-anneaux d'intercirculation) occupant une position surbaissée. La disposition des freins à disque permet d'utiliser un diamètre standard pour les disques malgré le plancher surbaissé. Du fait que ce bogie est placé sous les demi-anneaux d'intercircula- tion, on a les mêmes qualités de stabilité de roulement dans les deux sens de circulation et les véhicules équipés d'un tel bogie sont alors bidirectionnels. Par ailleurs, les efforts des caisses sont directement transmis au bogie sans que ces efforts passent par l'articulation reliant les deux caisses. Les roues sont élastiques et l'agencement des freins favorise le montage et le démontage.The object of the present invention is to provide a load-bearing bogie, in particular for a tram, having wheels of standard diameter and making it possible to provide, directly above, a central part of the floor (in the intercirculation half-rings) occupying a lowered position. . The arrangement of disc brakes allows the use of a standard diameter for discs despite the lowered floor. Because this bogie is placed under the intercirculation half-rings, there are the same qualities of rolling stability in the two traffic directions and the vehicles equipped with such a bogie are then bidirectional. Furthermore, the efforts of the boxes are directly transmitted to the bogie without these efforts passing through the joint connecting the two boxes. The wheels are elastic and the arrangement of the brakes promotes assembly and disassembly.

Le bogie selon l'invention est caractérisé par le fait qu'il comporte au moins deux essieux constitués par une poutre transversale qui s'étend en partie basse et réunit deux pièces d'appui des ressorts, chaque pièce d'appui étant disposée du côté interne de la roue correspondante.The bogie according to the invention is characterized in that it comprises at least two axles constituted by a transverse beam which extends in the lower part and joins two support pieces of the springs, each support piece being arranged on the side internal of the corresponding wheel.

Le bogie est monté de préférence sous un ensemble d'intercirculation monté entre deux caisses.The bogie is preferably mounted under an intercirculation assembly mounted between two boxes.

A l'extérieur de chaque roue est monté avantageusement un frein à disque dont le disque est solidaire de la roue et est décalé de celle-ci, ladite roue étant élastique.A disc brake is advantageously mounted on the outside of each wheel, the disc of which is integral with the wheel and is offset from the latter, said wheel being elastic.

Les fusées sont, soit solidaires des pièces d'appui, soit solidaires des roues et guidées par des roulements dans les pièces d'appui.The rockets are either integral with the supporting parts, or integral with the wheels and guided by bearings in the supporting parts.

En se référant aux dessins, le bogie est monté sous les extrémités de deux caisses de véhicule. L'articulation comporte un ensemble d'intercircu- lation 6 (en deux parties ou constituant le module central), qui permet le passage des voyageurs entre les caisses. Les caisses peuvent pivoter l'une par rapport à l'autre autour d'un axe transversal et autour d'un axe vertical (pivotement relatif dans le plan horizontal).Referring to the drawings, the bogie is mounted under the ends of two vehicle bodies. The articulation comprises an intercirculation assembly 6 (in two parts or constituting the central module), which allows the passage of travelers between the boxes. The boxes can pivot relative to each other around a transverse axis and around a vertical axis (relative pivoting in the horizontal plane).

Le bogie comprend un châssis 1 constitué de longerons 11 réunis par deux traverses 12.The bogie comprises a chassis 1 made up of longitudinal members 11 joined by two cross members 12.

Le châssis s'appuie, par l'intermédiaire de ressorts 4 de suspension primaire, sur des essieux fixes 3 qui portent les roues 2. Les ressorts 4 servent à l'appui vertical du châssis, à t'entraînement transversal et au guidage transversal des essieux.The chassis is supported, by means of primary suspension springs 4, on fixed axles 3 which carry the wheels 2. The springs 4 are used for the vertical support of the chassis, for the transverse drive and for the transverse guiding of the axles.

Chaque essieu est constitué par une poutre transversale 33 qui réunit en s'étendant en partie basse deux pièces d'appui 32 des ressorts supportant chacune une fusée 31 de roue de manière que ladite fusée 31 soit située plus haut que ladite poutre transversale 33.Each axle consists of a transverse beam 33 which, by extending in the lower part, two support pieces 32 of springs, each supporting a wheel spindle 31 so that said spindle 31 is located higher than said transverse beam 33.

Chaque essieu présente une forme coudée due au fait que le haut de la poutre transversale 33 se situe au-dessous de l'axe de la fusée 31. Cette forme coudée permet le logement du plancher de l'ensemble d'intercirculation sensiblement au-dessous de la génératrice supérieure des fusées.Each axle has a bent shape due to the fact that the top of the transverse beam 33 is located below the axis of the spindle 31. This bent shape allows the housing of the floor of the intercirculation assembly substantially below of the upper rocket generator.

Dans le mode de réalisation de la figure 4, les fusées 31 sont solidaires (en s'étendant vers l'extérieur) des pièces d'appui 32. Chaque roue 2 est guidée sur la fusée correspondante par l'intermédiaire de roulements à rouleaux 25 et 26.In the embodiment of FIG. 4, the spindles 31 are integral (extending outward) with the support pieces 32. Each wheel 2 is guided on the corresponding spindle by means of roller bearings 25 and 26.

Dans le mode de réalisation de la figure 6, les fusées 31 sont solidaires des roues et sont guidées par des roulements 25 et 26 dans les pièces d'appui 32.In the embodiment of FIG. 6, the rockets 31 are integral with the wheels and are guided by bearings 25 and 26 in the support parts 32.

Chaque pièce d'appui 32 sert d'appui à deux ressorts 4 de suspension primaire qui portent un longeron du châssis de manière à réaliser l'appui vertical, l'entraînement transversal et le guidage transversal. A titre indicatif, chaque ressort 4 est du type sandwich et supporte un longeron 11. Chaque sandwich 4 est constitué, de manière connue en soi, par des plaques en matériau élastomère et par des plaques métalliques intercalaires adhérisées à l'élastomère, les plaques métalliques terminales étant fixées respectivement à une pièce d'appui 32 et à un longeron 11 du châssis. Les deux sandwichs 4 associés à une même pièce d'appui 32 sont montés de manière que les plaques métalliques soient inclinées et convergent vers le haut et que l'élastomère travaille en compression et cisaillement. Chaque pièce d'appui 32 présente, en vue de côté, une forme en trapèze dont la petite base se situe à la partie supérieure.Each support piece 32 serves as a support for two primary suspension springs 4 which carry a frame beam so as to produce the vertical support, the transverse drive and the transverse guide. As an indication, each spring 4 is of the sandwich type and supports a spar 11. Each sandwich 4 is constituted, in a manner known per se, by plates of elastomeric material and by intermediate metal plates adhered to the elastomer, the metal plates terminals being fixed respectively to a support piece 32 and to a side member 11 of the chassis. The two sandwiches 4 associated with the same support piece 32 are mounted so that the metal plates are inclined and converge upwards and that the elastomer works in compression and shear. Each support piece 32 has, in side view, a trapezoid shape whose small base is located at the top.

Pour la suspension primaire on pourrait envisager par exemple une paire de ressorts coniques ou une combinaison de ressorts métalliques hélicoïdaux associés à des ressorts en élastomère.For the primary suspension, a pair of conical springs or a combination of helical metal springs associated with elastomer springs could be envisaged, for example.

Chaque roue 2 présente deux anneaux élastiques d'amortissement 23 qui sont enserrés entre des anneaux 21-27 situés à la périphérie du voile de roue et le bandage de roue 22. Ce bandage 22 est tenu par les formes biconiques de l'extérieur des anneaux 21-27, des anneaux élastiques 23 et de l'alésage du bandage 22. L'anneau 27 qui est démontable permet le montage et le démontage.Each wheel 2 has two elastic damping rings 23 which are sandwiched between rings 21-27 located at the periphery of the wheel disc and the wheel tire 22. This tire 22 is held by the biconical shapes on the outside of the rings 21-27, elastic rings 23 and the bore of the bandage 22. The ring 27 which is removable allows mounting and dismounting.

Chaque roue est équipée d'un frein à disque 5 constitué d'un disque de frein 51 et d'un étrier 52 portant les plaquettes de frein. Le disque de frein 51 est solidaire du moyeu de roue par l'intermédiaire d'une virole 511. Le disque est monté à l'extérieur de la roue 2 en étant déporté par rapport à celle-ci. Les étriers 52 sont fixés au châssis de bogie. Le diamètre extérieur du disque 51 peut être inférieur au diamètre de l'alésage du bandage 22 de manière à faciliter le montage et le démontage.Each wheel is fitted with a disc brake 5 consisting of a brake disc 51 and a caliper 52 carrying the brake pads. The brake disc 51 is secured to the wheel hub via a ferrule 511. The disc is mounted outside of the wheel 2 while being offset relative to the latter. The stirrups 52 are fixed to the bogie chassis. The outside diameter of the disc 51 can be less than the diameter of the bore of the tire 22 so as to facilitate assembly and disassembly.

Chaque roue est équipée d'un capteur de mesure de rotation 81. Ce capteur est monté en bout de la fusée 31 portant la roue 2 et sert à mesurer la rotation de la roue en fournissant un signal représentatif de cette rotation à un dispositif d'anti-enrayage connu qui commande le défrei- nage.Each wheel is equipped with a rotation measurement sensor 81. This sensor is mounted at the end of the spindle 31 carrying the wheel 2 and is used to measure the rotation of the wheel by providing a signal representative of this rotation to a device for known anti-braking device which controls brake release.

Dans le mode de réalisation des figures 1 à 3, l'ensemble repère 6 s'appuie, de chaque côté, sur un longeron 11 du châssis par des ressorts de suspension secondaire 7 de manière à permettre le pivotement relatif des caisses autour d'un axe transversal et d'un axe vertical.In the embodiment of Figures 1 to 3, the reference assembly 6 is supported, on each side, on a beam 11 of the chassis by secondary suspension springs 7 so as to allow the relative pivoting of the boxes around a transverse axis and a vertical axis.

Dans le mode de réalisation de la figure 7, l'ensemble central de caisse s'appuie sur les longerons 11 du châssis par des coussins pneumatiques.In the embodiment of FIG. 7, the central body assembly is supported on the side members 11 of the chassis by pneumatic cushions.

L'ensemble central 6 est relié transversalement à une traverse 12 du châssis de bogie par un amortisseur transversal 92 qui est attelé par des articulations à la traverse et à l'anneau.The central assembly 6 is connected transversely to a cross member 12 of the bogie frame by a transverse damper 92 which is coupled by articulations to the cross member and to the ring.

De chaque côté, la suspension secondaire est associée à un amortisseur vertical 91 qui est monté vers l'extérieur.On each side, the secondary suspension is associated with a vertical damper 91 which is mounted towards the outside.
