Description

La présente invention concerne un châssis de bogie comportant deux longerons reliés par au moins une traverse, le bogie pouvant être moteur ou porteur.The present invention relates to a bogie chassis comprising two side members connected by at least one cross member, the bogie being able to be motor or carrier.

D'une manière connue, les châssis de bogie fabriqués par moulage le sont en une seule opération, de sorte que le châssis est monobloc. Une telle fabrication impose l'utilisation de modèles de fonderie, de fours de traitement et de machines d'usinage, de grandes dimensions, donc coûteux.In a known manner, the bogie frames produced by molding are produced in a single operation, so that the frame is in one piece. Such manufacture requires the use of foundry models, treatment ovens and machining machines, of large dimensions, therefore expensive.

D'une manière également connue, les châssis de bogie sont fabriqués par mécano-soudage à partir de tôles d'acier. Les deux longerons sont réalisés de cette manière et la ou les traverses peuvent être soit réalisées de cette manière, soit constituées de tubes. On assemble le tout par soudage pour constituer un châssis fini monobloc. L'utilisation du soudage pour relier les longerons et les traverses impose donc pour tout le châssis, l'emploi d'un matériau unique et soudable, en général l'acier.In a manner also known, the bogie frames are manufactured by mechanical welding from steel sheets. The two beams are made in this way and the cross member (s) can either be made in this way, or consist of tubes. We assemble everything by welding to form a one-piece finished chassis. The use of welding to connect the side members and the crosspieces therefore requires, for the entire chassis, the use of a single weldable material, generally steel.

La présente invention a pour but de rendre le châssis modulaire pour faciliter les opérations de maintenance et autoriser une certaine évolutivité de la conception du châssis. Ce but est atteint par l'utilisation de liaisons mécaniques, ceci permettant de réaliser des composants de manière indépendante tels qu'un longeron ou une traverse, et de les assembler ensuite par boulonnage. Deux composants adjacents peuvent ainsi être réalisés dans deux matériaux différents, incompatibles du point de vue du soudage.The present invention aims to make the chassis modular to facilitate maintenance operations and allow a certain scalability of the chassis design. This object is achieved by the use of mechanical connections, this making it possible to produce components independently such as a spar or a cross member, and then to assemble them by bolting. Two adjacent components can thus be produced in two different materials, incompatible from the point of view of welding.

La réalisation de chaque composant peut se faire par moulage ou par mécano-soudage. La réalisation par moulage permet l'emploi de modèles de fonderie, de fours de traitement et de machines d'usina­ge, de petites dimensions, et permet l'emploi d'un matériau, un alliage léger par exemple, réputé non soudable donc non utilisable dans le cas du mécano-soudage.The production of each component can be done by molding or by mechanical welding. The production by molding allows the use of foundry models, treatment ovens and machining machines, of small dimensions, and allows the use of a material, a light alloy for example, deemed non-weldable therefore not usable in the case of mechanical welding.

La présente invention a pour objet un châssis de bogie comportant deux longerons reliés par au moins une traverse, caractérisé en ce que la ou les traverses sont reliées aux longerons par des liaisons mécaniques fixes constituées de surfaces assemblées par boulonnage. Un châssis de bogie moteur comporte une traverse et un châssis de bogie porteur comporte deux traverses.The present invention relates to a bogie frame comprising two longitudinal members connected by at least one cross member, characterized in that the cross member or cross members are connected to the longitudinal members by fixed mechanical connections consisting of surfaces assembled by bolting. A motor bogie frame has a cross member and a carrier bogie frame has two cross members.

Le châssis de bogie peut comporter un ou deux longerons secondai­res qui supportent une partie de l'effort de torsion dû au freinage ainsi que les efforts dûs aux butées de caisse et aux barres anti­roulis, afin de soulager les longerons principaux.The bogie frame may include one or two secondary beams which support part of the torsional force due to braking as well as the forces due to body stops and anti-roll bars, in order to relieve the main beams.

Il est décrit ci-après, à titre d'exemple et en référence aux dessins annexés, deux modes de réalisation du châssis de bogie selon l'invention, le premier mode représentant un châssis de bogie moteur et le deuxième mode représentant un châssis de bogie porteur.

Dans la figure 2, représentant un châssis porteur, ce châssis comporte deux longerons 10, 20 et deux traverses 30, 40. Ce châssis peut comporter en outre, un longeron secondaire central, ou tels que représentés, deux longerons secondaires latéraux 50, 60, le longeron secondaire 50 étant adjacent au longeron principal 10 et le longeron secondaire 60 étant adjacent au longeron principal 20.In FIG. 2, representing a support frame, this frame comprises two longitudinal members 10, 20 and two crosspieces 30, 40. This chassis may further comprise a central secondary spar, or as shown, two lateral secondary spars 50, 60, the secondary beam 50 being adjacent to the main beam 10 and the secondary beam 60 being adjacent to the main beam 20.

En présence de longerons secondaires, les liaisons peuvent être réalisées par des boulons traversant chacun les quatre couronnes, par exemple, les couronnes 22, 64, 62, 33.In these FIGS. 1 and 2, the fixed mechanical connections between two adjacent crowns, are made up of surfaces assembled by bolting, and these surfaces are planar but of course, in order to improve the positioning of the crowns between them, the connections can comprise an interlocking circular. In the presence of secondary beams, the connections can be made by bolts each passing through the four crowns, for example, the crowns 22, 64, 62, 33.

La barre 36 comporte une plaque de liaison 36A, et les deux plaques 36A, 66A sont reliées par boulon­nage.The beam 61 of the secondary spar 60 is extended, beyond the connection rings, by a protuberance 66 terminated by a connection plate 66A.
