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 de 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 welding point of view.

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 ainsi que les longerons possèdent des surfaces de liaison assurant, par assemblage et boulonnage, des liaisons mécaniques fixes entre les longerons et la ou les traverses.
Un châssis de bogie moteur comporte une traverse et un châssis de bogie porteur comporte deux traverses.The subject of the present invention is a bogie frame comprising two longitudinal members connected by at least one cross member, characterized in that the cross member (s) as well as the longitudinal members have connecting surfaces ensuring, by assembly and bolting, fixed mechanical connections between the side members and the cross member (s).
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.There are described below, by way of example and with reference to the accompanying drawings, two embodiments of the bogie chassis according to the invention, the first mode representing a motor bogie chassis and the second mode representing a bogie chassis carrier.

Les longerons 10, 20 se composent chacun d'une poutre 11, 21 et d'une couronne de liaison 12, 22, la couronne 22 du longeron 20 étant clairement représentée.The side members 10, 20 each consist of a beam 11, 21 and a connecting ring 12, 22, the ring 22 of the side member 20 being clearly shown.

La traverse 30 se compose d'un tube 31 portant un pivot central 31A et deux couronnes de liaison 32, 33.The cross-member 30 consists of a tube 31 carrying a central pivot 31A and two connecting rings 32, 33.

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.
