This object is achieved by separating the shock absorbers from the body, these then being connected to the bogie chassis and to the levers of the anti-roll bar, the movements of the body being transmitted to the shock absorbers by means of the connecting rods.
- this new arrangement requires only two supports integral with the body (two connecting rod supports) instead of four in the conventional arrangement (two connecting rod supports and two shock absorber supports), which facilitates maintenance operations. and in particular the lifting of the box.
- the present invention relates to a railway vehicle of which at least one bogie chassis comprises an anti-roll bar acting on the secondary suspension, the anti-roll bar comprising, at each end, a lever connected to the body via '' a connecting rod, the secondary suspension comprising at least two springs and two shock absorbers, the springs being installed between the vehicle body and the bogie chassis, characterized in that one end of each shock absorber is connected to the bogie chassis and in that the other end of each shock absorber is connected to a anti-roll bar lever.

Abstract
Description
La présente invention concerne un véhicule ferroviaire dont au moins un châssis de bogie comporte une barre anti-roulis agissant sur la suspension secondaire, la barre anti-roulis comportant, à chaque extrémité, un levier relié à la caisse par l'intermédiaire d'une bielle.The present invention relates to a railway vehicle of which at least one bogie chassis comprises an anti-roll bar acting on the secondary suspension, the anti-roll bar comprising, at each end, a lever connected to the body via a connecting rod.
Les véhicules ferroviaires se composent généralement d'une caisse et de deux bogies. Un bogie comporte un châssis, et la caisse est reliée à ce châssis de bogie par l'intermédiaire d'une suspension, dite secondaire, qui se compose généralement de deux gros ressorts à boudin et de deux amortisseurs, un couple ressort-amortisseur étant installé verticalement, sur un côté de la caisse.Railway vehicles generally consist of a body and two bogies. A bogie has a chassis, and the body is connected to this bogie chassis by means of a suspension, called secondary, which generally consists of two large coil springs and two shock absorbers, a spring-shock absorber couple being installed. vertically, on one side of the body.
Cette disposition classique entraîne, lors de mouvements relatifs entre caisse et bogie, des débattements importants de l'attache élastique située à chaque extrémité d'un amortisseur et ceci selon plusieurs axes, ce qui oblige à utiliser des rotules relativement coûteuses.This conventional arrangement causes, during relative movements between the body and the bogie, significant deflections of the elastic fastener situated at each end of a shock absorber and this along several axes, which means that relatively expensive ball joints have to be used.
La présente invention a pour but de remplacer les rotules par de simples articulations cylindriques sollicitées uniquement en torsion et suivant un seul axe. Ce but est atteint en séparant les amortisseurs de la caisse, ceux-ci étant alors reliés au châssis de bogie et aux leviers de la barre anti-roulis, les débattements de la caisse étant transmis aux amortisseurs par l'intermédiaire des bielles.The object of the present invention is to replace the ball joints by simple cylindrical articulations which are stressed only in torsion and along a single axis. This object is achieved by separating the shock absorbers from the body, these then being connected to the bogie chassis and to the levers of the anti-roll bar, the movements of the body being transmitted to the shock absorbers by means of the connecting rods.
Pour un bogie, cette nouvelle disposition ne nécessite que deux supports solidaires de la caisse (deux supports de bielles) au lieu de quatre dans la disposition classique (deux supports de bielles et deux supports d'amortisseurs), ce qui facilite les opérations de maintenance et en particulier le levage de la caisse.For a bogie, this new arrangement requires only two supports integral with the body (two connecting rod supports) instead of four in the conventional arrangement (two connecting rod supports and two shock absorber supports), which facilitates maintenance operations. and in particular the lifting of the box.
La présente invention a pour objet un véhicule ferroviaire dont au moins un châssis de bogie comporte une barre anti-roulis agissant sur la suspension secondaire, la barre anti-roulis comportant, à chaque extrémité, un levier relié à la caisse par l'intermédiaire d'une bielle, la suspension secondaire comportant au moins deux ressorts et deux amortisseurs, les ressorts étant installés entre la caisse du véhicule et le châssis de bogie caractérisé en ce qu'une extrémité de chaque amortisseur est reliée au châssis de bogie et en ce que l'autre extrémité de chaque amortisseur est reliée à un levier de la barre anti-roulis.The present invention relates to a railway vehicle of which at least one bogie chassis comprises an anti-roll bar acting on the secondary suspension, the anti-roll bar comprising, at each end, a lever connected to the body via '' a connecting rod, the secondary suspension comprising at least two springs and two shock absorbers, the springs being installed between the vehicle body and the bogie chassis, characterized in that one end of each shock absorber is connected to the bogie chassis and in that the other end of each shock absorber is connected to a anti-roll bar lever.
De préférence, un levier comporte deux bras, un bras relié à une extrémité d'une bielle, et un autre bras relié à une extrémité d'un amortisseur.Preferably, a lever comprises two arms, an arm connected to one end of a connecting rod, and another arm connected to one end of a damper.
Il est décrit ci-après, à titre d'exemple et en référence aux dessins annexés, un véhicule ferroviaire selon l'invention.
- La figure 1 montre un côté d'un bogie du véhicule.
- La figure 2 est une coupe suivant II de la figure 1.
- Figure 1 shows a side of a bogie of the vehicle.
- FIG. 2 is a section along II of FIG. 1.
Dans la figure 1 sont représentés, schématiquement et en vue partielle, la caisse 1 du véhicule, le châssis 2 d'un des deux bogies, vu de côté, un des deux ressorts 3 du bogie, un des deux amortisseurs 4, et une des quatre roues 5 du bogie. Cette figure montre aussi une barre anti-roulis 6 et une bielle 8. La barre 6 est mieux visible en figure 2. Le levier 7 comporte deux bras 7a, 7b.In Figure 1 are shown, schematically and in partial view, the
La bielle 8 est reliée au bras 7a par l'intermédiaire d'une rotule 9 et à un support 11, solidaire de la caisse 1, par l'intermédiaire d'une rotule 10.The connecting rod 8 is connected to the
L'amortisseur 4 est relié au bras 7b par l'intermédiaire d'une articulation cylindrique 12, et à un support 14, solidaire du châssis de bogie 2, par l'intermédiaire d'une articulation cylindrique 13.The
La bielle 8 et le levier 7 de la barre anti-roulis 6 sont donc utilisés pour transmettre, à l'amortisseur, les déplacements verticaux entre la caisse et le châssis de bogie.The connecting rod 8 and the
Un choix judicieux des longueurs des bras 1a et 1b permet de régler l'amortissement en utilisant des amortisseurs standard en ce qui concerne la course et la viscosité.A judicious choice of the lengths of the arms 1a and 1b makes it possible to adjust the damping using standard dampers with regard to the stroke and the viscosity.
L'invention s'applique à des barres de torsion à paliers intérieurs aux leviers, comme cela est représenté dans la figure 2, mais bien entendu, elle s'applique également à des barres de torsion à paliers extérieurs.The invention applies to torsion bars with bearings inside the levers, as shown in FIG. 2, but of course, it also applies to torsion bars with external bearings.
En outre, cette position horizontale des amortisseurs est particulièrement intéressante dans le cas de véhicules ferroviaires à plancher bas.In addition, this horizontal position of the shock absorbers is particularly advantageous in the case of low-floor railway vehicles.
