Description

La présente invention a pour obJet un bogie double pour une tour d assemblage de fusée. The object of the present invention is a double bogie for a rocket assembly tower.

Les fusées de grandes dimensions sont généralement assemblées à 1 intérieur d'une tour. Une fois la fusée assemblée la tour est évacuée pour permettre le lancement de ladite fusée. Large rockets are generally assembled inside 1 of a tower. Once the rocket is assembled, the tower is evacuated to allow the launch of the rocket.

A cet effet. la tour comporte. entre autres. For this purpose. the tower has. among others.

une superstructure verticale assurant le maintien de la fusée, et est munie de moyens de traction et de déplacement de 1 ensemble. a vertical superstructure ensuring the maintenance of the rocket, and is provided with means of traction and displacement of 1 assembly.

Ces moyens de traction et de déplacement peuvent être formés notamment par des mécanismes de roulement du type à bogie double prévus à chaque ex trémite de la tour et qui se déplacent sur des voies de roulement constituées par exemple par des rails. These traction and displacement means can be formed in particular by rolling mechanisms of the double bogie type provided at each ex hopper of the tower and which move on rolling tracks constituted for example by rails.

La tour repose sur les bogies doubles par 1 intermédiaire d organes de liaison qui, compte tenu de la charge importante supportée. doivent être suffisamment dimenslonnes et assurer une répartition uniforme de ladite charge sur chaque roue des bogies. The tower rests on the double bogies by 1 intermediary of connecting members which, taking into account the heavy load supported. must be sufficiently large and ensure a uniform distribution of the said load on each wheel of the bogies.

De plus. ces organes de liaison doivent egalement assurer une bonne stabilité à l ensemble de la tour, tout en permettant des mouvements de faible amplitude et de faible vitesse.Furthermore. these connecting members must also ensure good stability for the entire tower, while allowing movements of low amplitude and low speed.

Jusqu' présent, les organes de liaison entre les bogies doubles et la tour sont constitués par des pièces massives usinées et formées par des articulations mécaniques du genre rotules ou roulements à rouleaux. Ce genre de pièces est bien évi-demment d un poids important et nécessite des usinages précis ce qui augmente le coût d'une telle installation. D autre part, elles sont sujettes à des usures pouvant entrainer une immobilisation prolongée de la plateforme.  Until now, the connecting members between the double bogies and the tower have consisted of massive parts machined and formed by mechanical joints of the ball and socket or roller bearing type. This kind of parts is obviously of significant weight and requires precise machining which increases the cost of such an installation. On the other hand, they are subject to wear which can lead to prolonged immobilization of the platform.

L'invention a donc pour but de créer un bogie double pour une tour d'assemblage de fusée comportant des organes de liaison avec la tour qui se distingue par une économie de poids. une simplification de fabrication devenant de ce fait moins onéreuse. en évitant en même temps toute usure. The invention therefore aims to create a double bogie for a rocket assembly tower having connecting members with the tower which is distinguished by a saving in weight. a simplification of manufacture thereby becoming less expensive. avoiding at the same time any wear.

La présente invention a ainsi pour objet un bogie double pour tour d'assemblage de fusée comportant un premier-sous-bogie muni de deux essieux reliés entre eux par un-longeron, un second sous-bogie muni de deux essieux reliés également par un longeron. les deux longerons étant attelés l'un à l'autre par un pivot horizontal, et un palonnier d'équilibrage supportant ladite tour, caractérisé en ce que le palonnier d'équilibrage repose sur chacun des sous-bogies par l'intermédiaire de blocs d'appui élastiques et que la tour repose sur le palonnier d'équilibrage également par l'intermédiaire de blocs d'appui élastiques. The present invention thus relates to a double bogie for rocket assembly tower comprising a first sub-bogie provided with two axles connected together by a spar, a second sub-bogie provided with two axles also connected by a spar . the two side members being coupled to each other by a horizontal pivot, and a balancing spreader supporting said tower, characterized in that the balancing spreader rests on each of the sub-bogies by means of blocks d 'elastic support and that the tower rests on the balancing spreader also by means of elastic support blocks.

Sur les figures 1 et 2, on a représenté une tour 1 destinée au montage et l'assemblage d'une fusée de grandes dimensions, non représentée. Pour cela. In Figures 1 and 2, there is shown a tower 1 for mounting and assembling a large rocket, not shown. For that.

elle comporte une superstructure verticale 2 permettant d'accéder aux différents éléments de la fusée et de la maintenir en position.it has a vertical superstructure 2 allowing access to the various elements of the rocket and keeping it in position.

Par ailleurs, cette tour doit également pouvoir se déplacer. In addition, this tower must also be able to move.

A cet effet, la tour 1 repose. à chacune de ses extrémités. sur des mécanismes de roulement formés par des bougies doubles 10 qui se déplacent sur deux voies de roulement parallèles 3 et 4. Chaque bogie double 10 est muni de moyens d entrainement indépendants constitués, par exemple. par des moteurs hydrauliques 11. For this purpose, tower 1 rests. at each of its ends. on rolling mechanisms formed by double spark plugs 10 which move on two parallel rolling tracks 3 and 4. Each double bogie 10 is provided with independent drive means constituted, for example. by hydraulic motors 11.

En se reportant maintenant aux figures 3 à 5. on va décrire un bogie double, les autres bogies étant identiques. Referring now to Figures 3 to 5. we will describe a double bogie, the other bogies being identical.

Chaque bogie double 10 est constitué d'un premier sous-bogie 20 et d'un second sous-bogie 30 at telés entre eux, comme on le verra ultérieurement. Each double bogie 10 is constituted by a first sub-bogie 20 and a second sub-bogie 30 at teles between them, as will be seen later.

Le premier sous-bogie 20 comprend deux es sieux 21 et 22 muni chacun de deux galets de roulement 23 et reliés entre eux par un longeron 24 réalisé comme un profilé du type en caisson. Le longeron 24 comporte sur sa face supérieure une plaque d'appui horizontale 24a qui s'étend entre les deux essieux 21 et 22 de chaque côte de l'axe longitudinal du sous-bogie 20 (Figure 4). The first sub-bogie 20 comprises two seats 21 and 22 each provided with two rollers 23 and connected together by a spar 24 produced as a profile of the box type. The spar 24 has on its upper face a horizontal support plate 24a which extends between the two axles 21 and 22 on each side of the longitudinal axis of the sub-bogie 20 (Figure 4).

Le second sous-bogie 30 comprend de manière identique deux essieux 31 et 32 munis chacun de deux galets de roulement 33 et reliés entre eux par un longeron 34. Ce longeron 34 comporte sur sa face supérieure une plaque d'appui horizontale 34a qui s'étend entre les deux essieux 31 et 32.  The second sub-bogie 30 identically comprises two axles 31 and 32 each provided with two rollers 33 and connected together by a spar 34. This spar 34 has on its upper face a horizontal support plate 34a which s extends between the two axles 31 and 32.

Par ailleurs, un galet horizontal est monté au-dessous du longeron 24 du premier sous-bogie 20 entre les deux essieux 21 et 22. Ce galet horizontal 25 placé au niveau et entre les rails de la voie de roulement assure le guidage transversal du premier sous-bogie. Furthermore, a horizontal roller is mounted below the spar 24 of the first sub-bogie 20 between the two axles 21 and 22. This horizontal roller 25 placed at the level and between the rails of the track provides transverse guidance of the first sub-bogie.

Le second sous-bogie 30 comporte également dans sa partie centrale un galet horizontal 35 de guidage transversal. The second sub-bogie 30 also has in its central part a horizontal roller 35 for transverse guide.

Les longerons 24 et 34 des sous-bogies 20 et 30 sont reliés entre eux par un pivot horizontal 12 autorisant un débattement angulaire entre les deux sous-bogies. The side members 24 and 34 of the sub-bogies 20 and 30 are interconnected by a horizontal pivot 12 allowing angular movement between the two sub-bogies.

Pour assurer entre les deux sous-bogies 20 et 30 une répartition uniforme de la charge constituée par la charge de la tour 1. ladite tour 1 repose s.ur chacun des bougies doubles 10 par l'intermédiaire d'un palonnier d'équilibrage 5. To ensure between the two sub-bogies 20 and 30 a uniform distribution of the load constituted by the load of the tower 1. said tower 1 rests on each of the double spark plugs 10 by means of a balancing spreader 5 .

A cet effet, le longeron 24 du premier sousbogie 20 comporte sur la plaque horizontale 24a deux organes de liaison élastiques 26 placés chacun de part et d'autre de l'axe longitudinal du bogie. To this end, the spar 24 of the first sub-truck 20 has on the horizontal plate 24a two elastic connecting members 26 each placed on either side of the longitudinal axis of the bogie.

Il en est de même pour le second sous-bogie 30 qui comporte sur la plaque horizontale 34a deux organes de liaison élastiques 26. It is the same for the second sub-bogie 30 which comprises on the horizontal plate 34a two elastic connecting members 26.

Par conséquent, le palonnier 5 est en appui sur chaque sous-bogie 20 et 30 par l'intermédiaire de deux organes élastiques 26, ce qui permet de répartir uniformément la charge et de maintenir les galets 23 et 33 en appui sur les voies de roulement 3 et 4. Consequently, the lifter 5 is supported on each sub-bogie 20 and 30 by means of two elastic members 26, which makes it possible to distribute the load uniformly and to keep the rollers 23 and 33 supported on the tracks. 3 and 4.

Comme on le voit sur la figure 5, les organes de liaison 26 sont formés de blocs élastiques comportant des feuillets d'élastomère 26a entre les sont intercalées des lamelles metal.liquos 26b
Ces blocs élastiques comportent egalement-des moyens pour interdire les déplacements transversaux qui peuvent être formés par exemple par une butée centrale 26c encastrée dans la plaque horizontale 24a du longeron 24 pour le sous-bogie 20 et dans la plaque horizontale 34a du longeron 34 pour le sous-bogie 30.As seen in Figure 5, the connecting members 26 are formed of elastic blocks comprising elastomer sheets 26a between are interposed metal.liquos lamellae 26b
These elastic blocks also comprise means for preventing transverse displacements which can be formed for example by a central stop 26c embedded in the horizontal plate 24a of the spar 24 for the sub-bogie 20 and in the horizontal plate 34a of the spar 34 for the sub-bogie 30.

Enfin, la tour 1 est en appui, à chacune de ses extrémités, sur la partie supérieure du palonnier 5 de chaque bogie double 10, également par l intermé- diaire d'un organe de liaison élastique 6. Finally, the tower 1 is supported, at each of its ends, on the upper part of the lifter 5 of each double bogie 10, also by means of an elastic connecting member 6.

Cet organe de liaison élastique 6, placé au centre du palonnier 5 pour obtenir une répartition uniforme de la charge, se compose, comme pour les précédents, d'un bloc élastique comportant des feuillets d'élastomère 6a entre lesquels sont intercalées des lamelles métalliques 6b, et par exemple une butée centrale 6c. This elastic connecting member 6, placed in the center of the lifter 5 to obtain a uniform distribution of the load, consists, as for the previous ones, of an elastic block comprising elastomer sheets 6a between which metal lamellas 6b are interposed , and for example a central stop 6c.

Cette disposition confère à l'ensemble de la tour une bonne stabilité et assure un appui uniforme des galets de chaque bogie double sur la voie de roulement. This arrangement gives the whole tower good stability and ensures uniform support of the rollers of each double bogie on the track.

De plus. l'utilisation de blocs d'appui élastiques comme organes de liaison présente de nombreux avantages. Furthermore. the use of elastic support blocks as connecting members has many advantages.

En effet, ces blocs de liaison élastiques, tout en permettant aux éléments entre lesquels ils sont placés des mouvements de faible amplitude et de faible vitesse, supportent des charges importantes pouvant atteindre plusieurs milliers de tonnes, et sont d'un faible poids par rapport aux organes utili sés auparavant. Indeed, these elastic connecting blocks, while allowing the elements between which they are placed movements of low amplitude and low speed, support large loads of up to several thousand tonnes, and are of low weight compared to organs previously used.

Grâce à ces blocs de liaison élastiques, on simplifie la fabrication qui devient moins onéreuse et on évite en même temps toute usure et risque de grip page des articulations. Les écarts de répartition de la charge sur les galets de roulement, dûs au couple de frottement des articulations, sont également diminués.  Thanks to these elastic connection blocks, the manufacturing is simplified which becomes less expensive and at the same time all wear and risk of page grip of the joints is avoided. The load distribution differences on the rollers, due to the friction torque of the joints, are also reduced.
