Description

SYSTEME DE GUIDAGE A RAIL ET GALET A GORGE GUIDE SYSTEM WITH RAIL AND THROTTLE
La présente invention est relative à un système de guidage d'un véhicule équipé de roues directrices à bandage pneumatique, comprenant un rail et un galet à gorge destiné à suivre le rail, ledit galet à gorge étant monté flottant à l'extrémité d'un bras directionnel couplé aux roues directrices à bandage pneumatique du véhicule destiné à suivre une voie banalisée.The present invention relates to a system for guiding a vehicle equipped with pneumatic tire steering wheels, comprising a rail and a grooved roller intended to follow the rail, said grooved roller being mounted floating at the end of a directional arm coupled to the pneumatic tire steering wheels of the vehicle intended to follow an unmarked track.
Le bras directionnel s'étend parallèlement au rail. Il est orienté dans le sens de déplacement du véhicule, lorsqu'il porte le galet devant lui et est généralement complété par un second bras orienté dans le sens opposé au sens de déplacement du véhicule, c'est-à-dire un bras support qui tire un second galet de guidage comme décrit dans le brevet européen n° 0 062 370 du déposant.The directional arm extends parallel to the rail. It is oriented in the direction of movement of the vehicle, when it carries the roller in front of it and is generally completed by a second arm oriented in the direction opposite to the direction of movement of the vehicle, that is to say a support arm which pulls a second guide roller as described in European patent No. 0 062 370 of the applicant.
Le rail suivant l'invention trouve sa principale application dans les véhicules guidés par rail destinés à une voie banalisée compatible avec une voirie normale. Généralement, le rail est enfoui dans une ornière ménagée dans une chaussée ou est posé à la surface du sol en site propre. Par le document WO 88/00544, on connaît déjà un véhicule rapide de transport en commun muni d'une sustentation par pneumatique et d'un guidage auto atiσue le long d'une piste prédéterminée au moyen d'un galet à gorge gui suit un rail. Bien qu'aucune description précise du rail ne soit donnée dans ce document, on peut en déduire que le rail utilisé était semblable à ceux utilisés pour les ponts roulants. Un tel rail comporte une table de roulement horizontale délimitée par des flancs verticaux reliés à ladite table par des arrondis de 2 à 5 mm inhérents au laminage du rail. Quant au galet de guidage, il présente une gorge de section en U délimitée par la jante du galet et deux mentonnets de part et d'autre du rail.The rail according to the invention finds its main application in rail-guided vehicles intended for an unmarked track compatible with normal roads. Generally, the rail is buried in a rut in a pavement or is placed on the surface of the ground in a clean site. From document WO 88/00544, a rapid public transport vehicle is already known which is provided with pneumatic lift and self-guided guidance along a predetermined track by means of a grooved roller which follows a rail. Although no precise description of the rail is given in this document, it can be deduced that the rail used was similar to those used for overhead traveling cranes. Such a rail comprises a horizontal rolling table delimited by vertical sides connected to said table by rounding of 2 to 5 mm inherent in the rolling of the rail. As for the guide roller, it has a U-shaped groove delimited by the rim of the roller and two studs on either side of the rail.
Ce rail connu présente néanmoins des défauts d'adhérence et de bruyance que l'on peut expliquer par une analyse minutieuse des formes complémentaires des sections du rail et de la gorge du galet. En effet, tout déplacement latéral du galet dû à un déport latéral du bras support ou une courbe de la piste, d'amplitude supérieure au jeu entre le rail et le galet, fait que le mentonnet du galet bute contre le flanc de rail. Puisque le mentonnet du galet et le flanc du rail sont tous deux compris dans un même plan vertical, leur surface de contact coïncide avec celle d'un segment de cercle dont le rayon est égal au rayon extérieur du mentonnet et la corde à la génératrice du rail gui longe le bord inférieur de l'arrondi.This known rail nevertheless has adhesion and noisiness defects which can be explained by a careful analysis of the complementary shapes of the sections of the rail and of the groove of the roller. Indeed, any lateral movement of the roller due to a lateral offset of the support arm or a curve of the track, of amplitude greater than the clearance between the rail and the roller, means that the peg of the roller abuts the rail flank. Since the pebble of the roller and the side of the rail are both included in the same vertical plane, their contact surface coincides with that of a segment of a circle whose radius is equal to the outside radius of the bead and the cord to the generator of the rail which runs along the lower edge of the flare.
La vitesse relative de chacun des points de contact du mentonnet du galet par rapport au rail, varie proportionnellement à la distance gui le sépare du centre instantané de rotation de la jante du galet sur la table de roulement du rail. Les points de contact du galet qui présentent les vitesses relatives les plus élevées et les pressions de contact les plus fortes de la part du rail subiront les usures les plus importantes et causeront le plus de nuisance sonore.The relative speed of each of the contact points of the peg of the roller with respect to the rail varies in proportion to the distance which separates it from the instantaneous center of rotation of the rim of the roller on the running table of the rail. The contact points of the roller which have the highest relative speeds and the highest contact pressures on the part of the rail will suffer the most wear and will cause the most noise pollution.
La présente invention vise à remédier aux inconvénients susdits et éviter nombre d'autres défauts liés à l'utilisation d'un roulement fer sur fer, notamment risque de déraillage et défaut d'adhérence. Elle propose dans ce but un rail laminé tel que décrit dans le préambule de la revendication 1 ci-annexée. Le but visé est atteint lorsque la table de roulement du rail comprend des flancs inclinés rentrants.The present invention aims to remedy the above drawbacks and to avoid a number of other defects linked to the use of an iron-on-iron bearing, in particular the risk of derailment and lack of adhesion. To this end, it proposes a laminated rail as described in the preamble of claim 1 appended hereto. The aim is achieved when the rail running table includes re-entrant inclined sides.
Suivant une particularité de l'invention, les flancs du rail présentent un angle d'inclinaison <x par rapport à la verticale compris entre 5 et 15e. Dans une forme de réalisation particulière, au moins un des flancs comporte une portion de surface supérieure verticale et une portion de surface inférieure inclinée, les deux portions de surface susdites étant séparées par une génératrice parallèle au rail.According to a feature of the invention, the sides of the rail have an angle of inclination <x relative to the vertical of between 5 and 15 e . In a particular embodiment, at least one of the sides has a vertical upper surface portion and an inclined lower surface portion, the two above-mentioned surface portions being separated by a generator parallel to the rail.
Ces particularités ainsi que d'autres particulari¬ tés et détails de l'invention apparaîtront dans la description détaillée suivante qui fait référence aux dessins ci-annexés, qui représentent à titre d'exemple illustratif et non limitatif, deux formes de réalisation particulières de l'invention.These features as well as other features and details of the invention will appear in the following detailed description which refers to the accompanying drawings, which illustrate by way of illustrative and non-limiting example, two particular embodiments of the 'invention.

- les figures 11 et 12 montrent un galet sur un rail selon l'invention, ainsi σue le pivotement vertical dudit galet. Dans ces figures, les mêmes signes de référence désignent des éléments identiques et/ou analogues.- Figures 11 and 12 show a roller on a rail according to the invention, thus σue the vertical pivoting of said roller. In these figures, the same reference signs designate identical and / or analogous elements.
La figure 1 montre en élévation latérale, un galet de guidage 2 monté flottant à l'extrémité d'un bras directionnel 3 d'un système de guidage d'un véhicule équipé de roues directrices à bandage pneumatique destiné à suivre une voie banalisée. Un dispositif de sustentation non montré appuie le galet 2 sur le rail. Le rail 1 est constitué d'un profilé en acier laminé comprenant une table de roulement 4 plate ou bombée, dressée sur une âme 5 renforcée par une semelle inférieure 6 gui déborde de chaque côté de l'âme 5.Figure 1 shows in side elevation, a guide roller 2 mounted floating at the end of a directional arm 3 of a guidance system of a vehicle equipped with pneumatic tire steering wheels intended to follow an unmarked track. A lifting device not shown supports the roller 2 on the rail. The rail 1 consists of a rolled steel section comprising a flat or curved tread table 4, erected on a core 5 reinforced by a lower sole 6 which overflows on each side of the core 5.
Le galet 2 présente une gorge 10 en forme d'auge à versants droits. La gorge 10 est délimitée par la jante du galet et deux mentonnets 21 verticaux qui longent les flancs 20 du rail, comme illustré dans la figure 2.The roller 2 has a groove 10 in the form of a trough with straight slopes. The groove 10 is delimited by the rim of the roller and two vertical studs 21 which run along the sides 20 of the rail, as illustrated in FIG. 2.
A ce jour, le rail considéré comme étant le mieux adapté pour le guidage d'un véhicule du type susdit était un rail destiné aux ponts roulants. Un tel rail est représenté aux figures 3 et 4 en même temps que le galet à gorge avec lequel il coopère. Il comporte une table de roulement 4 horizontale délimitée par des flancs verticaux reliés à ladite table par des arrondis de 2 à 5 mm de rayon. Le parallélisme des mentonnets 21 du galet et des flancs 20 du rail l,fait σue ceux-ci se touchent suivant une surface de contact gui s'étend à toute la portion de surface du mentonnet située sous la jante du galet lorsque le galet bute contre le rail. Or, les points de contact éloignés du centre instantané de rotation i de la jante du galet sur la face de roulement du rail 4 présentent une vitesse relative par rapport au rail élevée. Les points de contact du galet qui présentent les vitesses relatives les plus élevées et les pression de contact les plus fortes de la part du rail, engendrent les vibrations les plus fortes et subissent l'usure la plus forte.To date, the rail considered to be best suited for guiding a vehicle of the above type was a rail intended for overhead traveling cranes. Such a rail is shown in Figures 3 and 4 together with the grooved roller with which it cooperates. It comprises a horizontal rolling table 4 delimited by vertical sides connected to said table by rounding of 2 to 5 mm in radius. The parallelism of the studs 21 of the roller and of the sides 20 of the rail l, makes these touch in a mistletoe contact surface extends to the entire surface portion of the chin located under the rim of the roller when the roller abuts the rail. However, the contact points distant from the instantaneous center of rotation i of the rim of the roller on the rolling face of the rail 4 have a relative speed with respect to the high rail. The contact points of the roller which have the highest relative speeds and the highest contact pressures on the part of the rail, generate the strongest vibrations and undergo the greatest wear.
Pour réduire les vitesses relatives des points de contacts éloignés, la présente invention propose un rail de guidage dont la table de roulement 4 est délimitée latéralement par des flancs inclinés 20 rentrants. De cette manière, les zones de contact entre les mentonnets 21 du galet compris dans des plans verticaux et des flancs 20 du rail compris dans des plans inclinés, sont limitées à une bande de contact 12 très étroite gui longe le bord inférieur de chaque arrondi 13 qui borde chaque côté de la table de roulement 4 du galet. L'inclinaison 2 des flancs inclinés latéraux des rails par rapport à la verticale est par exemple d'environ 10°.To reduce the relative speeds of distant contact points, the present invention provides a guide rail, the tread table 4 of which is delimited laterally by re-entrant inclined sides 20. In this way, the contact zones between the jaws 21 of the roller included in vertical planes and the sides 20 of the rail included in inclined planes, are limited to a very narrow contact strip 12 which runs along the lower edge of each rounded 13 which borders each side of the rolling table 4 of the roller. The inclination 2 of the lateral inclined sides of the rails with respect to the vertical is for example around 10 °.
De manière générale, chacun des points de cette bande de contact est moins éloigné du centre instantané de rotation i de la jante du galet sur la table de roulement du rail. L'efficacité de chacun des mentonnets 21 pour assurer le maintien du galet sur le rail n'en n'est pas modifiée. En effet, le frottement F du mentonnet 21 contre le flanc 20 du rail crée une certaine force de freinage qui aligne le galet sur le rail par libre pivotement du galet autour d'un axe vertical. Le pivotement P du galet ramène la jante vers une trajectoire idéale le long d'une ligne médiane de la table de roulement du rail (voir Figures 11 et 12).In general, each of the points of this contact strip is less distant from the instantaneous center of rotation i of the rim of the roller on the rolling table of the rail. The effectiveness of each of the studs 21 for ensuring the maintenance of the roller on the rail is not modified. Indeed, the friction F of the chin 21 against the side 20 of the rail creates a certain braking force which aligns the roller on the rail by free pivoting of the roller around a vertical axis. The pivoting P of the roller brings the rim towards an ideal trajectory along a center line of the rail running table (see Figures 11 and 12).
Le système de guidage décrit ci-dessus n'implique qu'un faible jeu du galet par rapport au rail pour éviter le coincement dudit galet. The guidance system described above involves only a small clearance of the roller relative to the rail to avoid jamming of said roller.
