Abstract

The mounting is for wheel-set guides on powered rail-bound vehicles axle bearings. The guides are located one behind the other, in pairs. They are hinged to the vehicle frame, so as not to twist, via hole in the cylinder bolts; and to the axle-bearing housing. A rubber layer is fastened on the bolts periphery, and on the holes sheathing surface, with initial stressing. The rubber layer (32) extends only over part of the length of at least one of the two cylinder bolts (30) of a hinge system. Over the remaining length there is a stop socket (31), permitting radial play on either the internal or the external dia. This can consist of two part sockets, at the two ends of the bolt. Radial play pref. amounts to 3-4% of bolt dia.

Description

La présente invention se rapporte à un dispositif de montage de guides d'essieux pour boites d'essieux de véhicules de traction ferroviaires, dans lequel les guides d'essieux se succèdent deux à deux dans la direction du déplacement, sont articulés sur le logement de palier de l'essieu et sont également articulés sur le châssis du véhicule, sans pouvoir tourner, par l'intermédiaire d'axes cylindriques logés dans des trous desdits guides d'essieux, une couche de caout Il chouc (silentbloc) étant fixée avec précharge, d'une part sur la périphérie desdits axes cylindriques et, d'autre part, sur la surface de l'enveloppe desdits trous. The present invention relates to a device for mounting axle guides for axle boxes of railway traction vehicles, in which the axle guides follow one another in pairs in the direction of movement, are articulated on the housing of bearing of the axle and are also articulated on the chassis of the vehicle, without being able to turn, by means of cylindrical axes housed in holes in said axle guides, a layer of rubber It is fixed with preload , on the one hand on the periphery of said cylindrical axes and, on the other hand, on the surface of the envelope of said holes.

On se référera au brevet DE-C-2 735 574. Le dispositif de montage illustré dans ce brevet crée une rigidit considérable du palier d'essieu dans le sens longitudinal, ce qui entraîne d'une part, lors du démarrage du véhicule de traction avec une grande puissance, une contrainte notable imposée au silentbloc"et, autre part, à grande vitesse, se traduit par de grandes forces de déport transversal des essieux sur les rails. Reference is made to patent DE-C-2 735 574. The mounting device illustrated in this patent creates considerable rigidity of the axle bearing in the longitudinal direction, which leads on the one hand, when starting the traction vehicle with great power, a notable constraint imposed on the silentbloc "and, on the other hand, at high speed, results in great forces of transverse offset of the axles on the rails.

Conformément à l'invention, ces inconvénients sont éliminés par le fait que la couche de caoutchouc s'étend seulement sur une partie de la longueur d'au moins l'un des deux axes cylindriques d'un mécanisme d'articulation ; et par le fait que, sur le reste de la longueur, il est prévu une douille de butée qui autorise un jeu radial soit sur le diamètre interne, soit sur le diamètre externe. Selon d'autres perfectionnements avantageux de 1 'invention, la douille de butée peut se composer de deux douilles partielles disposées aux deux extrémités de l'axe cylindrique. Le jeu radial peut représenter entre environ 3 % et 4 % du diamètre dudit axe cylindrique.En outre, lorsque les guides d'essieux présentent cnacun deux axes cylindriques de longueur différ-ente, la douille de butée peut être prévue sur l'axe cylindrique le plus court
L'invention va à présent être décrite plus en détail à titre d'exemple nullement limitatif en regard du dessin annexé sur lequel
la figure 1 est une élévation latérale fragmentaire d'un bogie de locomotive muni de guides d'essieux ; et
la figure 2 est une vue en plan avec coupe longitudinale partielle dudit bogie.
According to the invention, these drawbacks are eliminated by the fact that the rubber layer extends only over part of the length of at least one of the two cylindrical axes of an articulation mechanism; and by the fact that, over the rest of the length, an abutment sleeve is provided which allows radial play either on the internal diameter or on the external diameter. According to other advantageous improvements of the invention, the stop sleeve can consist of two partial sockets arranged at the two ends of the cylindrical axis. The radial clearance can represent between approximately 3% and 4% of the diameter of said cylindrical axis. In addition, when the axle guides have two cylindrical axes of different length, the abutment sleeve can be provided on the cylindrical axis. the shortest
The invention will now be described in more detail by way of non-limiting example with regard to the appended drawing in which
Figure 1 is a fragmentary side elevation of a locomotive bogie with axle guides; and
Figure 2 is a plan view with partial longitudinal section of said bogie.

Sur la figure 1, un logement de palier 2 d'un essieu ferroviaire comportant un cadre de bogie 3 d'une locomotive non représentée est articulé sur des guides d'essieu 4 et 5 qui se succèdent dans le sens du déplacement et sont parallèles l'un à l'autre. Leur fixation est assurée, sur des coquilles cylindriques 7 et 8 du logement de palier 2 et sur des coquilles cylindriques 6 et 9 du cadre de bogie 3, par l'intermédiaire de pièces profilées 10 et 11 du guide d'essieu 4 qui s'ajustent dans des évidements des coquilles cylindriques 6 et 7, par l'intermédiaire de pièces profilées 12 et 13 du guide d'essieu 5 qui s'adaptent à des évidements des coquilles 8 et 9, ainsi que par l'intermédiaire de membrures associées 14 à 17. In FIG. 1, a bearing housing 2 of a railway axle comprising a bogie frame 3 of a locomotive not shown is articulated on axle guides 4 and 5 which follow one another in the direction of movement and are parallel l to each other. Their fixing is ensured, on cylindrical shells 7 and 8 of the bearing housing 2 and on cylindrical shells 6 and 9 of the bogie frame 3, by means of profiled parts 10 and 11 of the axle guide 4 which fit into recesses of cylindrical shells 6 and 7, by means of profiled parts 12 and 13 of the axle guide 5 which adapt to recesses of the shells 8 and 9, as well as by means of associated members 14 to 17.

Alors que les côtés marginaux ouverts des coquilles cylindriques 8 et 9 sont orientés dans des directions mutuellement opposées, les côtés marginaux ouverts des coquilles cylindriques 6 et 7 sont tournés dans le même sens. While the open marginal sides of the cylindrical shells 8 and 9 are oriented in mutually opposite directions, the open marginal sides of the cylindrical shells 6 and 7 are rotated in the same direction.

La figure 2 représente les pièces profilées 10 et 11 du guide d'essieu 4. Comme le montre la coupe longitudinale partielle de ce guide 4, les pieces profilées 10 et 11 sont reliées l'une à l'autre par le biais d'un axe cylindrique 30. Sur la surface circonférentielle de cet axe, se trouve une couche de caoutchouc 32 qui est empêchée de tourner et est maintenue en place avec précharge dans un fourreau 33. Ce fourreau 33 est empêché de tourner dans le boîtier du guide d'essieu 4. FIG. 2 represents the profiled parts 10 and 11 of the axle guide 4. As shown in the partial longitudinal section of this guide 4, the profiled parts 10 and 11 are connected to each other by means of a cylindrical axis 30. On the circumferential surface of this axis, there is a layer of rubber 32 which is prevented from rotating and is held in place with preload in a sleeve 33. This sleeve 33 is prevented from rotating in the housing of the guide axle 4.

La couche de caoutchouc 32 permet la rotation élastique des pièces profilées 10 et 11 par rapport au guide d'essieu. Elle empêche que se produisent des mouvements de glissement mutuel de pièces métalliques qui provoqueraient une usure accrue. En outre, sur le guide d'essieu, sont prévus des disques 34 en caoutchouc à armure métallique qui sont maintenus en place avec précharge par une bague métalli que 35 en appui contre une bague fendue 36. Ces disques 34 confèrent au guide d'essieu 4 une élasticité limitée dans le sens axial. On évite de la sorte que des parties métalliques viennent directement heurter les unes contre les autres, ce qui s' assortit. d'une usure accrue, et l'on augmente ainsi la longévité du guide d'essieu. The rubber layer 32 allows the elastic rotation of the profiled parts 10 and 11 relative to the axle guide. It prevents mutual sliding movements of metal parts which would cause increased wear. In addition, on the axle guide, there are provided discs 34 of metal armored rubber which are held in place with preload by a metal ring that 35 bears against a split ring 36. These discs 34 give the axle guide 4 a limited elasticity in the axial direction. This avoids that metal parts directly strike against each other, which matches. increased wear, thereby increasing the service life of the axle guide.

La couche de caoutchouc 32 ne s'étend pas sur toute la longueur de l'axe cylindrique 30, mais seulement dans la région médiane, sur environ la moitié de la longueur dudit axe 30. Dans la région marginale de cet axe, sont prévues deux parties 31 d'une douille de butée portant par leurs surfaces circonférentielles externes contre le trou du guide d'essieu 4, mais accusant un jeu, sur leurs surfaces circonférentielles internes, par rapport audit axe cylindrique 30. The rubber layer 32 does not extend over the entire length of the cylindrical axis 30, but only in the middle region, over approximately half the length of said axis 30. In the marginal region of this axis, two are provided parts 31 of an abutment sleeve bearing by their external circumferential surfaces against the hole in the axle guide 4, but showing play on their internal circumferential surfaces with respect to said cylindrical axis 30.

Cette caractéristique crée les avantages susmentionnés.This feature creates the aforementioned advantages.

Il va de soi que de nombreuses modifications peuvent être apportées au dispositif décrit et représenté, sans sortir du cadre de l'invention.  It goes without saying that numerous modifications can be made to the device described and shown, without departing from the scope of the invention.
