Abstract

The rail vehicle suspension comprises a spring (3) interposed between a support table (4) of an axle box (5) and a chassis support zone (6). The suspension also has a shock absorber (7) and a friction piece (8) carried by the axle box. The longitudinal axis (10) of each spring is inclined by an angle (X) to the perpendicular of the chassis support plane. This angle is relative to a vertical plane transverse to the chassis displacement direction. Thus, all displacements of the axle box in a vertical plane generate a force whose horizontal component (F), parallel to the bogey longitudinal axis, accentuates rubbing of the friction piece on the chassis fixed part.

Description

L'invention se rapporte à une suspension pour véhicule ferroviaire.The invention relates to a suspension for a railway vehicle.

Par véhicule ferroviaire, on comprendra tant un boggie qu'un wagon sous la caisse duquel sont montés directement les organes de roulement.By rail vehicle, we understand both a bogie and a wagon under the body of which the running gear are mounted directly.

Classiquement, tout véhicule ferroviaire est pourvu d'une suspension destinée notamment à absorber les chocs provoqués par les irrégularités des voies de roulement, par exemple pour donner un certain confort aux voyageurs.Conventionally, any rail vehicle is provided with a suspension intended in particular to absorb the shocks caused by irregularities in the running tracks, for example to give passengers some comfort.

On connaît principalement deux types de suspension pour véhicule ferroviaire.There are mainly two types of suspension for railway vehicles.

Le premier type de suspension est monté latéralement par rapport au plan vertical de l'axe de la roue et au plan radial de ladite roue.The first type of suspension is mounted laterally with respect to the vertical plane of the axis of the wheel and to the radial plane of said wheel.

Il est notamment utilisé pour le transport de marchandises.It is notably used for the transport of goods.

Cette suspension comprend, pour chaque roue, deux groupes de ressorts disposés de part et d 'autre d'une boite d'essieu qui, à cet effet, présente de part et d'autre une table d'appui pour la base des ressorts.This suspension comprises, for each wheel, two groups of springs arranged on either side of an axle box which, for this purpose, has on either side a support table for the base of the springs.

L'extrémité supérieure des ressorts prend appui au moins indirectement sur un élément du châssis, tel un des longerons d'un boggie et plus particulièrement cette extrémité supérieure prend appui à l'intérieur d'un chapeau relié au châssis par des anneaux obliques.The upper end of the springs bears at least indirectly on an element of the chassis, such as one of the side members of a bogie and more particularly this upper end bears on the inside of a cap connected to the chassis by oblique rings.

La paroi latérale d'un des chapeaux sollicite, en déplacement vers la face latérale de la boite d'essieu, une pièce de friction portée par un poussoir.The side wall of one of the caps urges, in movement towards the lateral face of the axle box, a friction piece carried by a pusher.

Cette pièce de friction agit comme un amortisseur.This friction piece acts as a shock absorber.

Chaque groupe de ressorts comprend un ressort de tare et un ressort de charge.Each group of springs includes a tare spring and a load spring.

Ce dernier n'entre en action qu'au delà d'une charge minimale par essieu. Ce groupe de ressorts est monté sensiblement perpendiculairement au plan d'appui du boggie.The latter only comes into action above a minimum axle load. This group of springs is mounted substantially perpendicular to the support plane of the bogie.

Bien que cette solution soit relativement rustique, elle nécessite un nombre relativement important de pièces et donc des temps d'assemblage relativement longs.Although this solution is relatively rustic, it requires a relatively large number of parts and therefore relatively long assembly times.

Le deuxième type de suspension connu est surtout utilisé couramment sur les véhicules de transport de voyageurs.The second known type of suspension is mainly used commonly on passenger transport vehicles.

Il comprend une boite d'essieu reliée au châssis par une biellette articulée autour d'axes horizontaux et transversaux par rapport à la direction du déplacement du véhicule.It includes an axle box connected to the chassis by a link articulated around horizontal and transverse axes relative to the direction of movement of the vehicle.

Cette suspension se situe sensiblement dans le même plan vertical que l'axe de la roue.This suspension is located substantially in the same vertical plane as the axis of the wheel.

La suspension est différente de la suspension précédente en ce sens qu'elle comprend une suspension primaire entre la roue et un élément de châssis et une suspension secondaire entre le châssis précité et une traverse porteuse du compartiment voyageur.The suspension is different from the previous suspension in that it comprises a primary suspension between the wheel and a chassis element and a secondary suspension between the aforementioned chassis and a carrying cross member of the passenger compartment.

Ainsi, la suspension primaire d'une roue se compose :

  • d'une part, d'un ressort unique prenant appui, pour sa base, sur la face supérieure de la boite d'essieu et pour son extrémité supérieure, sur la face inférieure d'un longeron qui constitue partiellement le châssis et surplombe la boite d'essieu et,
  • d'autre part, d'un amortisseur.
Thus, the primary suspension of a wheel consists of:
  • on the one hand, a single spring bearing, for its base, on the upper face of the axle box and for its upper end, on the lower face of a beam which partially constitutes the chassis and overhangs the box axle and,
  • on the other hand, a shock absorber.

Outre cette suspension primaire des roues, une suspension secondaire est interposée entre la face supérieure du boggie et une traverse de charge supportant le compartiment voyageur.In addition to this primary wheel suspension, a secondary suspension is interposed between the upper face bogie and a load cross member supporting the passenger compartment.

Cette suspension qui vise à améliorer le confort des voyageurs et le transport à grande vitesse est très coûteuse.This suspension, which aims to improve passenger comfort and high speed transport, is very expensive.

Un des résultats que l'invention vise à obtenir est une suspension du type cité plus haut qui remédie à ces inconvénients.One of the results which the invention aims to obtain is a suspension of the type mentioned above which overcomes these drawbacks.

A cet effet, l'invention a pour objet une telle suspension pour véhicule ferroviaire comprenant, pour chaque roue :

  • d'une part, au moins un ressort interposé entre une table d'appui présentée par une boite d'essieu et une zone d'appui présentée par le châssis et
  • d'autre part, un moyen d'amortissement des oscillations de la roue par frottement d'une pièce de friction portée par la boite d'essieu sur une partie fixe du châssis,
To this end, the subject of the invention is such a suspension for a railway vehicle comprising, for each wheel:
  • on the one hand, at least one spring interposed between a support table presented by an axle box and a support zone presented by the chassis and
  • on the other hand, a means of damping the oscillations of the wheel by friction of a friction piece carried by the axle box on a fixed part of the chassis,

cette suspension étant caractérisée en ce qu'au lieu que l'axe du ressort soit sensiblement perpendiculaire au plan contenant les axes des deux essieux dit plan d'appui du châssis du véhicule ferroviaire, l'axe longitudinal de chaque ressort est incliné d'un certain angle par rapport à cette perpendiculaire au plan d'appui du châssis et ce, par rapport à un plan vertical transversal au sens de déplacement du châssis de sorte que tout déplacement de la boite d'essieu dans un plan vertical génère une force dont la composante horizontale et parallèle à l'axe longitudinal du boggie accentue le frottement de la pièce de friction sur la partie fixe du châssis.this suspension being characterized in that instead of the axis of the spring being substantially perpendicular to the plane containing the axes of the two axles, said bearing plane of the chassis of the rail vehicle, the longitudinal axis of each spring is inclined by certain angle with respect to this perpendicular to the support plane of the chassis and this, with respect to a vertical plane transverse to the direction of movement of the chassis so that any movement of the axle box in a vertical plane generates a force whose horizontal and parallel component to the longitudinal axis of the bogie accentuates the friction of the friction piece on the fixed part of the chassis.

L'invention sera bien comprise à l'aide de la description ci-après faite à titre d'exemple non limitatif en regard du dessin ci-annexé qui représente schématiquement :

  • figure 1 : une vue en perspective d'un boggie,
  • figure 2 : une vue latérale d'une suspension selon l'invention,
  • figure 3 : une vue en coupe horizontale d'une suspension.
The invention will be better understood with the aid of the description below given by way of nonlimiting example with regard to the attached drawing which schematically represents:
  • FIG. 1: a perspective view of a bogie,
  • FIG. 2: a side view of a suspension according to the invention,
  • Figure 3: a horizontal sectional view of a suspension.

En se reportant au dessin, on voit que, pour améliorer le comportement d'un véhicule ferroviaire 1, celui ci dispose, pour chaque élément de roulement, d'une suspension 2.Referring to the drawing, it can be seen that, in order to improve the behavior of a railway vehicle 1, it has, for each rolling element, a suspension 2.

Classiquement, cette suspension 2 pour véhicule ferroviaire comprend, pour chaque roue :

  • d'une part , au moins un ressort 3 interposé entre une table 4 d'appui présentée par une boite d'essieu 5 et une zone 6 d'appui présentée par le châssis et
  • d'autre part, un moyen 7 d'amortissement des oscillations de la roue par frottement, d'une pièce de friction 8 portée par la boite d'essieu, sur une partie fixe du châssis.
Conventionally, this suspension 2 for a railway vehicle comprises, for each wheel:
  • on the one hand, at least one spring 3 interposed between a support table 4 presented by an axle box 5 and a support area 6 presented by the chassis and
  • on the other hand, a means 7 for damping the oscillations of the wheel by friction, of a friction piece 8 carried by the axle box, on a fixed part of the chassis.

La boite d'essieu présente avec le châssis un moyen de guidage dans un plan sensiblement vertical.The axle box with the chassis has a guide means in a substantially vertical plane.

Au lieu que l'axe 10 du ressort soit sensiblement perpendiculaire au plan P contenant les axes des deux essieux dit plan d'appui du châssis du véhicule ferroviaire, selon une caractéristique essentielle de l'invention, l'axe 10 longitudinal de chaque ressort est incliné d'un certain angle X par rapport à cette perpendiculaire au plan d'appui du châssis et ce, par rapport à un plan vertical transversal au sens de déplacement du châssis de sorte que tout déplacement de la boite d'essieu dans un plan vertical génère une force dont la composante F horizontale et parallèle à l'axe longitudinal du boggie accentue le frottement de la pièce 8 de friction sur la partie fixe du châssis.Instead of the axis 10 of the spring being substantially perpendicular to the plane P containing the axes of the two axles, said bearing plane of the chassis of the rail vehicle, according to an essential characteristic of the invention, the longitudinal axis 10 of each spring is inclined at a certain angle X relative to this perpendicular to the support plane of the chassis and this, relative to a vertical plane transverse to the direction of movement of the chassis so that any movement of the axle box in a vertical plane generates a force whose horizontal component F and parallel to the longitudinal axis of the bogie increases the friction of the friction piece 8 on the fixed part of the chassis.

Selon l'invention, l'angle X d'inclinaison de l'axe longitudinal des ressorts est compris entre 5° et 17°.According to the invention, the angle X of inclination of the longitudinal axis of the springs is between 5 ° and 17 °.

La zone d'appui supérieure du ressort est présentée par l'une des ailes d'une pièce 11, en forme de L renversé, fixée par tout moyen connu sur l'extrémité d'un longeron.The upper support zone of the spring is presented by one of the wings of a part 11, in the shape of an inverted L, fixed by any known means on the end of a spar.

La grande branche du L renversé est par exemple fixée par soudure à l'extrémité d'un longeron et la petite branche servant d'appui au ressort est inclinée par rapport au plan d'appui du châssis.The large branch of the inverted L is for example fixed by welding to the end of a beam and the small branch serving as support for the spring is inclined relative to the support plane of the chassis.

Pour améliorer la rigidité du montage précité, un gousset 12 est fixé, d'une part, sur le dos du L et, d'autre part, sur la face supérieure du longeron.To improve the rigidity of the above assembly, a gusset 12 is fixed, on the one hand, on the back of the L and, on the other hand, on the upper face of the spar.

La face supérieure de la boite 5 d'essieu constitue directement la table d'appui du ressort.The upper face of the axle box 5 directly constitutes the spring support table.

De préférence, chaque suspension comprend deux ressorts montés coaxialement et comprend en outre une butée 13 en matériau hyper-élastique.Preferably, each suspension comprises two springs mounted coaxially and further comprises a stop 13 made of hyper-elastic material.

Cette butée 13 se présente sous la forme d'une ogive ayant une course utile comprise entre 20 et 60 mm.This stop 13 is in the form of a warhead having a useful stroke of between 20 and 60 mm.

Le matériau utilisé, pour réaliser cette butée, est par exemple un élastomère.The material used, to achieve this stop, is for example an elastomer.

L'enveloppe des raideurs sous 25 mm de course effective se situe entre 60 et 320 N/mm.The stiffness envelope under 25 mm of effective travel is between 60 and 320 N / mm.

Avantageusement, la pièce de friction portée par la boite d'essieu est, par un moyen élastique 14, sollicitée constamment vers la partie fixe du châssis.Advantageously, the friction part carried by the axle box is, by elastic means 14, constantly urged towards the fixed part of the chassis.

A cet effet, le moyen élastique 14 est constitué par une lame élastique en forme de crosse dont la branche 14A sensiblement rectiligne est fixée sur la boite d'essieu latéralement à celle-ci et dont l'extrémité libre 14B prend appui derrière la branche verticale du L renversé .For this purpose, the elastic means 14 is constituted by an elastic blade in the form of a stick, the substantially straight branch 14A of which is fixed to the axle box laterally thereto and the free end 14B of which rests behind the vertical branch L reversed.

L'extrémité libre 14B de la lame est avantageusement repliée localement pour augmenter sa surface de contact avec la partie fixe du châssis.The free end 14B of the blade is advantageously folded locally to increase its contact surface with the fixed part of the chassis.

Cette partie fixe du châssis est avantageusement pourvue d'une plaque 15 en matériau plus résistant à l'usure tel un alliage en manganèse.This fixed part of the chassis is advantageously provided with a plate 15 of more wear-resistant material such as a manganese alloy.

La forme de la lame sera déterminée en fonction de la courbe souhaitée de progression du rappel, cette courbe pourra être linéaire mais de préférence elle sera de type exponentielle.The shape of the blade will be determined according to the desired curve of progression of the recall, this curve can be linear but preferably it will be of exponential type.

En cas de mouvement de lacet de l'essieu, la pièce de frottement de l'une des boites d'essieu tend à s'écarter du châssis et, de ce fait, c'est le moyen élastique 14 qui assure un minimum de contact et donc un minimum d'amortissement.In the event of yaw movement of the axle, the friction part of one of the axle boxes tends to move away from the chassis and, therefore, it is the elastic means 14 which ensures minimum contact and therefore a minimum of depreciation.

A cet effet, la loi de raideur du moyen élastique 14 est déterminée de façon à apporter beaucoup de réaction horizontale pour un faible déplacement horizontal.To this end, the law of stiffness of the elastic means 14 is determined so as to provide a lot of horizontal reaction for a small horizontal displacement.

En prévoyant ce moyen élastique, on ramène la pièce de friction contre le châssis.By providing this elastic means, the friction piece is brought back against the chassis.
