Abstract

The bogie for a railway vehicle travelling at high speeds, has an H shaped frame between two axles. This consists of two longitudinals (7,8) each supporting two wheels for one rail, connected by a tube (9). Each longitudinal is a channel, with a deep central web, of a size sufficient for the tube to pass through it. To allow each longitudinal to tilt independently, about the axis of the tube, the tube is in two sections with two bearings (12,13) between. A short tube section passes through the web of one longitudinal (8) and the other tube (9) through the other web, passes through this short section, with the bearings between.

Description

L'inyention a p6Cr objet un perfectionnement apporté aux bogies pour voitures ferrQyiaires,
De manière traditionnelle et en soi bien connue, un bogie se compose de deux paires de roues reliées entre elles par des essieux, l'ensemble étant solidarisé par une paire de longerons parallèles entre eux prenant appui indirectement sur les deux roues d'un même rail, les deux longerons étant reliés par une traverse et formant avec celleoci un ensemble monobloc en forme de H, Cet ensemble est muni dune suspension qui ne sera pas décrite plus en détail.The intention was to improve the bogies for railway cars,
Traditionally and in itself well known, a bogie consists of two pairs of wheels connected together by axles, the assembly being secured by a pair of parallel beams between them indirectly supported on the two wheels of the same rail. , the two side members being connected by a cross member and forming with that a H-shaped monobloc assembly, This assembly is provided with a suspension which will not be described in more detail.

Le chassis de la voiture (wagon) est articulé sur ce chariot de manière en soi connue. The chassis of the car (wagon) is articulated on this carriage in a manner known per se.

Les bogies connus donnent entierement satisfaction pour le trafic à grande vitesse sur voies régulières ou très peu détériorées. Toutefois sur les voies en mauvais état, la vitesse maximale est limitée pour les véhicules équipés de bogies de ce type,
La présente invention a pour objet de pallier cet inconvénient en proposant un bogie pour voiture ferroviaire, du type comportant deux longerons reliés par une traverse, caractérisé en ce que les deux longerons sont articulés l'un par rapport à l'autre de manière à ce que chacun d'entre eux puisse se déplacer indépendamment de l'autre dans le plan vertical du rail cor respondant/ autour de l'axe longitudinal de la traverse.The known bogies are entirely satisfactory for high speed traffic on regular tracks or very little deteriorated. However, on tracks in poor condition, the maximum speed is limited for vehicles fitted with bogies of this type,
The object of the present invention is to overcome this drawback by proposing a bogie for a railway car, of the type comprising two side members connected by a cross member, characterized in that the two side members are articulated with respect to each other so that that each of them can move independently of the other in the vertical plane of the corresponding rail / around the longitudinal axis of the crosspiece.

On comprendra mieux l'invention à l'aide de la description ci-après de deux variantes de mise en oeuvre, en référence aux dessins annexés dans lesquels
- la figure 1 est une vue latérale d'un bogie conforme à l'invention selon une première variante
- la figure 2 est une vue de dessus du bogie de la figure 1
- la figure 3 est une coupe selon A-A de la figue re 1 ;
- la figure 4 est une vue latérale d'un bogie conforme à l'invention selon une seconde variante
- la figure 5 est une vue de dessus du bogie de la figure 4
- la figure 6 est une coupe selon B-B, de la figure 4.The invention will be better understood with the aid of the description below of two alternative embodiments, with reference to the appended drawings in which
- Figure 1 is a side view of a bogie according to the invention according to a first variant
- Figure 2 is a top view of the bogie of Figure 1
- Figure 3 is a section along AA of fig re 1;
- Figure 4 is a side view of a bogie according to the invention according to a second variant
- Figure 5 is a top view of the bogie of Figure 4
FIG. 6 is a section along BB, of FIG. 4.

Le bogie comporte des roues (1,- 2g 3, 4) reliées

par pair; par des essieux (5r 6),
Les deux roues situées bsuT un.mEme rail sont re- liées entre elles par des longerons (7@ 8).Les deux longerons sont reliés entre eux par une traverse (9), sur laquelle s'arti- cule en (10) de manière en soi connue le chassis du véhicule,
Conformément à l'inventiont l'un au moins des longerons est monté pivotant dans un plan vertical sur la traverse tubulaire (9) en son extrémité (11), par l'intermédiaire d'une articulation comportant deux paliers (12 13)1 les deux longerons étant donc articulés l'un par rapport à l'autre.The bogie has wheels (1, - 2g 3, 4) connected
Figure img00020001

in pairs; by axles (5r 6),
The two wheels located bsuT un.mEme rail are interconnected by rails (7 @ 8) .The two rails are connected together by a cross (9), on which is articulated in (10) of in itself known the chassis of the vehicle,
According to the invention, at least one of the side members is pivotally mounted in a vertical plane on the tubular cross-member (9) at its end (11), by means of an articulation comprising two bearings (12 13) 1 les two beams therefore being articulated relative to each other.

Chaque longeron peut ainsi pivoter autour dé l'axe de la traverse (9) indépendamment l'un de l'autre dans le plan vertical du rail correspondant.Each spar can thus pivot around the axis of the crosspiece (9) independently of one another in the vertical plane of the corresponding rail.

Dans la réalisation des figures 4 à 6, les deux longerons sont montés pivotants l'un par-rapport à l'autre selon deux articulations (14, 15). Dans ce cas chaque longeron est solidaire chacun-d'une traverse tubulaire (16, 17), les deux traverses s'emboitant l'une dans 11 autre et s'articulant sur des paliers (18, 19). In the embodiment of Figures 4 to 6, the two beams are pivotally mounted relative to each other according to two joints (14, 15). In this case each spar is each secured to a tubular cross-member (16, 17), the two cross-members fitting one into another 11 and being articulated on bearings (18, 19).

Par rapport au précédent ce dispositif offre une meilleure rigidité, par suite de sa symétrie ce qui entraine une meilleure répartition des contraintes. Compared to the previous one, this device offers better rigidity, due to its symmetry, which results in a better distribution of the stresses.

Les deux dispositifs décrits permettent de rouler à vitesse en régime accéléré sur toute voie, et en particulier sur voie très déformée. The two devices described make it possible to travel at an accelerated speed on any track, and in particular on very deformed track.

On a décrit une application aux véhicules ferroviaires et il doit s'entendre que le dispositif conforme à l'invention couvre toutes les applications à des engins se déplaçant sur rails à savoir également les chariots sidérurgiques par exemple7  An application to rail vehicles has been described and it must be understood that the device according to the invention covers all applications to machines moving on rails, namely also steel carriages for example7
