Abstract

Les perfectionnements et les moyens selon cette invention sont surtout prévus pour des semi-remorques bimodaux spéciaux, pouvant circuler sur rails et sur route, selon la demande de Brevet Italien n.2124/A86 et Brevet Européen n.87830373.4 du même demandeur, dans lesquels non seulement le boggie ferroviaire, mais aussi le boggie routier sont amovibles: ils peuvent donc être appliqués même si le boggie routier est inamovible, ou bien sur tous semi-remorques bimodaux. Les perfectionnements résident dans la fourniture d'un système de couplage boggie ferroviaire/semi-remorque par une interface (1) applicable également, grâce à des modifications adéquates, à des boggies adapteurs c'est-à-dire des wagons boucliers antérieurs ou postérieurs, qui permettent l'introduction du semi-remorque dans un convoi ferroviaire formé de wagons conventionnels. Cette interface est reliée de manière stable au boggie ferroviaire par exemple au moyen d'un système crapaudine/broche de couplage et peut être tournée pour permettre l'accouplement au semi-remorque par les deux extrémités du boggie. Les moyens d'assemblage de l'interface au semi-remorque sont les mêmes pour le boggie intermédiaire et pour le wagon bouclier postérieur, tandis que l'on utilisera le système d'accrochage entre les semi-remorques pour le wagon bouclier antérieur. Les perfectionnements concernent également des moyens associés à la barre anti-emboîtement et à l'installation pneumatique du semi-remorque pour rendre plus sûr l'accrochage entre les semi-remorques, entraînant et contrôlant ainsi automatiquement le soulèvement du châssis.The improvements and the means according to this invention are especially intended for special bimodal semi-trailers, which can travel on rails and on the road, according to the request of Italian Patent n.2124 / A86 and European Patent n.87830373.4 of the same applicant, in which not only the railway bogie, but also the road bogie are removable: they can therefore be applied even if the road bogie is irremovable, or on all bimodal semi-trailers. Improvements reside in the supply of a railroad bogie / semi-trailer coupling system by an interface (1) which can also be applied, thanks to suitable modifications, to bogies adapters, i.e. front or rear bumper wagons , which allow the introduction of the semi-trailer in a railway convoy formed of conventional wagons. This interface is stably connected to the railway bogie, for example by means of a coupling plate / coupling pin and can be turned to allow coupling to the semi-trailer by the two ends of the bogie. The means of assembling the interface to the semi-trailer are the same for the intermediate bogie and for the rear shield wagon, while the attachment system between the semi-trailers will be used for the front shield wagon. The improvements also relate to means associated with the anti-nesting bar and the pneumatic installation of the semi-trailer to make more secure the coupling between the semi-trailers, thereby causing and automatically controlling the lifting of the chassis.

Description

Cette invention a pour objet des semi-remorques pouvant circuler sur rails comme des wagons ferroviaires et sur route comme des véhicules routiers, dans lesquels la transformation de véhicule ferroviaire à véhicule routier ou vice versa peut être effectuée sans l'intervention de grues,de plateforme de soulèvement ni d'autres systèmes de ce type.The subject of this invention is semi-trailers which can run on rails like railway wagons and on road like road vehicles, in which the transformation from rail vehicle to road vehicle or vice versa can be carried out without the intervention of cranes, platforms or other such systems.

Plus particulièrement, cette invention a pour objet des perfectionnements des semi-remorques bimodaux selon demande de Brevet italien 2124/A86 du 23.10.1986 et Brevet Européen 87830373 du 22.10.1987 du même demandeur, avec boggie routier amovible, pouvant circuler sur rails en formant un convoi de boggies ferroviaires et sur route comme des semi-remorques routiers normaux, respectivement avec uniquement le boogie ferroviaire ou uniquement avec le boggie routier, ou égale­ment avec les deux boogies si l'on ne veut pas extraire le boggie routier.More particularly, this invention relates to improvements in bimodal semi-trailers according to Italian patent application 2124 / A86 of 23.10.1986 and European patent 87830373 of 22.10.1987 of the same applicant, with removable road bogie, which can travel on rails forming a convoy of rail and road bogies like normal road semi-trailers, respectively with only the rail boogie or only with the road bogie, or also with the two boogies if you do not want to extract the road bogie.

Dans ces véhicules l'enchâssement du boggie ferroviaire est effectué en soulevant avec la suspension du boggie routier une extrémité du châssis du semi-remorque et, par la suite, après avoir franchi la crapaudine du boogie, en abaissant le châssis avec cette même suspension jusqu'à insérer la broche de couplage du semi-remorque dans la crapaudine du boggie.In these vehicles the embedding of the railway bogie is carried out by lifting with the suspension of the road bogie one end of the chassis of the semi-trailer and, afterwards, after having crossed the cogaudine of the boogie, by lowering the chassis with this same suspension until 'at insert the coupling pin of the semi-trailer into the bogie plate.

Cela provoque des difficultés de centrage de la broche de couplage du semi-remorque dans la crapaudine du boggie, pour les petites tolérances que nécéssite cette opération, et il faut que les suspensions du boogie routier puissent effectuer des prestations élevées de manière à permettre le soulèvement du semi-remorque chargé à plein, avec un coût des suspensions plus élevé.This causes difficulties in centering the coupling pin of the semi-trailer in the bogie of the bogie, for the small tolerances that this operation requires, and it is necessary that the suspensions of the road bogie can perform high performances so as to allow lifting of the semi-trailer fully loaded, with a higher cost of suspensions.

Cela est dû à la nécéssité d'effectuer une extra-course de 100mm. environ pour franchir la crapaudine avec la broche de couplage solidaire du boggie, et cela entraîne également une augmentation des temps de soulèvement.This is due to the need to perform an extra stroke of 100mm. approximately to cross the crapaudine with the coupling pin integral with the bogie, and this also leads to an increase in lifting times.

Pour remédier à cet inconvénient, pour les semi-remorques dans lesquels le boggie routier ne peut être extrait, les constructeurs de véhicules bimodaux route-rails ont réalisé des dispositifs qui permettent l'application du boggie ferroviaire sans que l'extrémité du semi-remorque ne soit obligée de se soulever au dessus de la crapaudine du boggie: ces dispositifs présentent cependant le défaut d'interférer avec les dispositifs d'accrochage réciproque entre les semi-remorques, c'est à dire qu'ils sont très compliqués et ne permettent pas un accrochage élastique.To overcome this drawback, for semi-trailers in which the road bogie cannot be extracted, the manufacturers of bimodal road-rail vehicles have produced devices which allow the application of the rail bogie without the end of the semi-trailer is not obliged to lift above the bogie plate: these devices however have the defect of interfering with the reciprocal hooking devices between the semi-trailers, that is to say that they are very complicated and do not allow not an elastic snap.

D'autre part, aussi bien les semi-remorques selon les deman­des de Brevet sus mentionnées, à savoir les semi-remorques pouvant circuler sur rails sans boggie routier, que les semi-remorques dans lesquels l'exercice sur rails s'effectue en maintenant en position soulevée le boggie routier, pour pouvoir être insérés dans un convoi ferroviaire normal en partie formé de wagons normaux, doivent être dotés de boogies adaptateurs spéciaux, appelés également boggies boucliers dans cette description, devant être appliqués aussi bien à la partie postérieure qu'à la partie antérieure du train de semi-remorques, lesquels peuvent être montés rapidement et ne nécéssitent pas une manutention excessive.On the other hand, both the semi-trailers according to the above-mentioned patent applications, namely the semi-trailers able to travel on rails without a road bogie, that the semi-trailers in which the exercise on rails is carried out while keeping the road bogie in the raised position, in order to be able to be inserted in a normal rail convoy partly formed by normal wagons, must be equipped with special adapter boogies, also called shield bogies in this description, which must be applied to both the rear and the front part of the train of semi-trailers, which can be fitted quickly and do not require excessive handling.

Le but principal de cette invention est d'améliorer la fonctionnalité des semi-remorques bimodaux route-rails, avec boggie routier amovible, et de fournir des moyens adaptables avec les modifications adéquates à tous les autres véhicules bimodaux route-rails, compris dans l'état de la technique.The main object of this invention is to improve the functionality of bimodal road-rail semi-trailers, with removable road bogie, and to provide means adaptable with the appropriate modifications to all other bimodal road-rail vehicles, included in the state of the art.

Un des buts particuliers est de fournir dans les wagons bimodaux sus mentionnés avec boogie routier amovible un dispositif unique permettant le montage rapide des boggies ferroviaires intermédiaires et du wagon bouclier postérieur, grâce à des modifications simples.One of the particular aims is to provide in the above-mentioned bimodal wagons with removable road bogie a unique device allowing the rapid assembly of the intermediate rail bogies and the rear shield wagon, thanks to simple modifications.

Un autre but important est de fournir un wagon bouclier à monter à l'extrémité antérieure du semi-remorque pouvant être monté en utilisant le même dispositif d'accrochage ferroviaire antérieur des semi-remorques.Another important object is to provide a shield wagon to be mounted at the front end of the semi-trailer which can be mounted using the same front rail coupling device for semi-trailers.

Un autre but important est de fournir des moyens qui rendent plus sûr l'accrochage entre les semi-remorques et qui inter­viennent en cas de rupture du dispositif d'accrochage princi­pal.Another important aim is to provide means which make the coupling between the semi-trailers more secure and which intervene in the event of a break in the main coupling device.

Un autre but de cette invention est de fournir des moyens qui interviennent automatiquement soit pour abaisser soit pour soulever le châssis du véhicule quand on passe de la circulation sur route à la circulation sur rails ou vice versa.Another object of this invention is to provide means which intervene automatically either to lower or to raise the chassis of the vehicle when passing from road traffic to rail traffic or vice versa.

A ces fins, l'invention résoud les problèmes suivants:

  • a) l'application des boggies intermédiaires et du wagon bouclier postérieur au semi-remorque par un dispositif qui évite le soulèvement de l'extrémité postérieure du semi-remorque au dessus de la crapaudine du boggie ferro­viaire, mais qui en même temps n'intervient pas avec les systèmes d'accrochage entre les semi-remorques;
  • b) l'application du wagon bouclier antérieur avec les moyens qui permettent l'accrochage entre les semi-remorques;
  • c) un système d'enchâssement de pivots de sécurité supplémen­taires dans le système d'accrochage entre les semi-remorques par l'intermédiaire d'une manoeuvre de la barre anti-emboî­tement.
To these ends, the invention solves the following problems:
  • a) the application of the intermediate bogies and the rear shield wagon to the semi-trailer by a device which prevents the rear end of the semi-trailer from being raised above the rail bogie, but which at the same time does not intervene not with the coupling systems between the semi-trailers;
  • b) the application of the front shield wagon with the means which allow attachment between the semi-trailers;
  • c) a system for embedding additional safety pivots in the coupling system between the semi-trailers by means of an operation of the anti-interlocking bar.

Le dispositif qui permet le montage du boogie ferroviaire CF à l'extrémité postérieure SR3 du semi-remorque, est formé d'une traverse nervurée spéciale 1, appelée également ici interface, qui forme une gorge 1c délimitée par des ailettes de guide 1a inclinées vers le bas, à la surface inférieure de laquelle est solidaire une broche de couplage R2 reliée à la crapaudine R1 du boggie par l'intermédiaire d'un pivot R3 muni d'un dé à l'extrémité.The device which allows the mounting of the railway boogie CF at the rear end SR3 of the semi-trailer, is formed by a special ribbed cross member 1, also called here interface, which forms a groove 1c delimited by guide fins 1a inclined towards the bottom, to the lower surface of which is fixed a coupling pin R2 connected to the baffle R1 of the bogie via a pivot R3 fitted with a die at the end.

Le blocage de l'interface 1 à l'extrémité du semi-remorque est effectué après l'enchâssement d'un pivot 2 solidaire de la poutre transversale SR3 du semi-remorque dans la gorge 1c, grâce à un crochet 1d maintenu en position de fermeture par un verrou 1b, et deux fourches 3 qui s'enfilent dans deux cavités tubulaires 3a dans la poutre transversale nervurée SR3; le verrou est manoeuvré par une poignée 1e et reste en position de déblocage du crochet quand l'encoche 1f s'introduit dans le bord latéral de l'interface.The blocking of the interface 1 at the end of the semi-trailer is carried out after the embedding of a pivot 2 secured to the transverse beam SR3 of the semi-trailer in the groove 1c, by means of a hook 1d held in the position of closing by a lock 1b, and two forks 3 which thread into two tubular cavities 3a in the ribbed transverse beam SR3; the lock is operated by a handle 1e and remains in the hook release position when the notch 1f is introduced into the lateral edge of the interface.

L'interface peut tourner, autour de l'axe du pivot R3 de la crapaudine du boggie, de 18O°, pour permettre le couplage du boggie au semi-remorque, des deux extrémités.The interface can rotate, around the axis of the pivot R3 of the bogie of the bogie, of 180 °, to allow the coupling of the bogie to the semi-trailer, of the two ends.

Dans ce but, on soulève la tige 9 qui maintient l'interface en position d'accrochage en la faisant pivoter dans le sens contraire des aiguilles d'une montre autour du pivot 9b, de manière à débloquer le taquet 9a de la fourchette 10 solidaire du boggie.To this end, the rod 9 is raised, which maintains the interface in the hooking position by pivoting it anti-clockwise around the pivot 9b, so as to unlock the cleat 9a of the integral fork 10. bogie.

La fourchette permet des rotations de l'interface de ± 5° autour de l'axe du pivot R3 de la crapaudine, de manière à pouvoir faciliter le couplage boggie/semiremorque et permettre les rotations normales du boggie pendant la marche ferroviaire.The fork allows rotations of the interface of ± 5 ° around the axis of the pivot R3 of the crapaudine, so as to be able to facilitate the coupling bogie / semitrailer and allow the normal rotations of the bogie during the railway operation.

La rotation de l'interface est facilitée par une plaque annulaire 6 solidaire du boggie CF, sur laquelle elle s'ap­ puie avec des roulettes 7 de manière à ce que son assiette demeure horizontale.The rotation of the interface is facilitated by an annular plate 6 integral with the bogie CF, on which it rests puie with casters 7 so that its plate remains horizontal.

Les plaques 4 en métal anti-frottement ont pour but de réduire le frottement rasant qui se vérifie pendant le couplage de l'interface au semi-remorque; le glissement des fourches 3 dans les cavités tubulaires 3a est facilité par la présence de plaques en métal antifrottement 3b.The purpose of the anti-friction metal plates 4 is to reduce the grazing friction which occurs during the coupling of the interface to the semi-trailer; the sliding of the forks 3 in the tubular cavities 3a is facilitated by the presence of anti-friction metal plates 3b.

Le blocage de l'interface au semi-remorque est ultérieurement assuré en cas d'urgence par deux pivots 8 dans la poutre nervurée SR3 qui s'enfilent dans deux trous 1G à axe vertical dans l'interface.The blocking of the interface to the semi-trailer is subsequently ensured in an emergency by two pivots 8 in the ribbed beam SR3 which thread into two holes 1G with vertical axis in the interface.

Le wagon bouclier postérieur est illustré sur la fig.8 et dérive du boggie intermédiaire en applicant à l'interface un châssis 1P d'un côté, et de l'autre un châssis 1Pc auquel sont reliés les repoussoirs 1Pc/1 et le dispositif d'accro chage aux wagons conventionnels.The rear shield wagon is illustrated in fig. 8 and derives from the intermediate bogie by applying to the interface a 1P chassis on one side, and on the other a 1Pc chassis to which the 1Pc / 1 pushers and the device are connected. 'addicted to conventional wagons.

Pour faciliter son introduction sous le châssis du semi-­remorque, le châssis 1Pa, à l'extrémité correspondante, est profilé de manière à former un plan incliné 1Pb: les ailettes IPd sont profilées de manière à faciliter l'intro­duction du pivot 2 dans la gorge 1c en maintenant leur surface au même niveau que l'aile supérieure du profilé 1Pa.To facilitate its introduction under the chassis of the semi-trailer, the chassis 1Pa, at the corresponding end, is profiled so as to form an inclined plane 1Pb: the fins IPd are profiled so as to facilitate the introduction of the pivot 2 in the groove 1c while maintaining their surface at the same level as the upper wing of the profile 1Pa.

Quand le wagon bouclier n'est pas appliqué au semi-remorque, c'est à dire quand il n'est pas en service, l'interface formée par la traverse nervurée 1 et par les châssis supplémentaires 1Pa et 1Pc, est maintenue en position horizontale par un dispositif 13 qui leur est relié, par l'intermédiaire d'un crochet 13a qui fait prise avec un taquet 14 solidaire du boggie ferroviaire.When the shield wagon is not applied to the semi-trailer, i.e. when it is not in service, the interface formed by the ribbed cross member 1 and by the additional frames 1Pa and 1Pc, is held in a horizontal position by a device 13 which is connected to them, by means of a hook 13a which engages with a cleat 14 secured to the railway bogie.

Ce dispositif 13 est muni de fourchettes 13c qui provoquent un blocage supplémentaire du châssis 1Pa avec le châssis SRI du semi-remorque quand le wagon bouclier est accouplé au semi-remorque: les manoeuvres du dispositif 13 sont effectuées grâce à un volant 13d et grâce à des engrenages placés dans une boîte 13b.This device 13 is provided with forks 13c which cause an additional blocking of the 1Pa chassis with the SRI chassis of the semi-trailer when the shield wagon is coupled to the semi-trailer: the operations of the device 13 are carried out using a steering wheel 13d and thanks to gears placed in a box 13b.

Le wagon bouclier antérieur est illustré sur la fig.11.The front shield wagon is illustrated in fig. 11.

Il se différencie du wagon postérieur uniquement par le système de couplage de l'interface 1A à l'extrémité anté­rieure du semi-remorque; en effet l'interface 1A constituée par les traverses nervurées 1, et par les profilés 1Ac sur lesquels sont montés les repoussoirs 1Ac/1 et le crochet de traction d'un côté, et de l'autre un dispositif 13, semblable au dispositif déjà monté sur le wagon bouclier postérieur, pour le blocage supplémentaire aux longerons SR1 du semiremorque et en alternative à une cheville 14 solidaire du boggie, est munie d'une sphère d'accrochage 15 semblable à la cheville SRA2 montée sur la poutre SR3 postérieure du semi-remorque, qui constitue avec la sphère cave SRA1 le dispositif d'accrochage SRA entre les semiremor­ ques.It differs from the rear wagon only by the interface coupling system 1A at the front end of the semi-trailer; in fact the interface 1A constituted by the ribbed crosspieces 1, and by the profiles 1Ac on which the pushers 1Ac / 1 and the traction hook are mounted on one side, and on the other a device 13, similar to the device already mounted on the rear shield wagon, for additional blocking to the longitudinal members SR1 of the semi-trailer and as an alternative to a dowel 14 secured to the bogie, is provided with a hooking sphere 15 similar to the dowel SRA2 mounted on the rear beam SR3 of the semi - trailer, which constitutes with the cellar sphere SRA1 the attachment device SRA between the semiremor ques.

Pour cela, l'accrochage du wagon bouclier antérieur s'effec­tue en reliant la sphère cave SRA1 à la sphère 15 montée sur le wagon bouclier et en bloquant successivement avec les crochets 13c du dispositif 13 le châssis 1Ac du wagon bouclier au longeron SR1.For this, the attachment of the front shield wagon is carried out by connecting the cellar sphere SRA1 to the sphere 15 mounted on the shield wagon and successively blocking with the hooks 13c of the device 13 the chassis 1Ac of the shield wagon to the spar SR1.

Les plaques 1Aa ont pour but de placer la partie antérieure du semi-remorque sur la sphère 15: la fermeture 1Ab appliquée sur la partie supérieure du châssis contribue également à cette manoeuvre.The purpose of the plates 1Aa is to place the front part of the semi-trailer on the sphere 15: the closure 1Ab applied to the upper part of the chassis also contributes to this maneuver.

Sur la fig. 6 est illustrée la barre anti-emboîtement A1 et la barre 11 qui permet sa rotation; cette barre tourne autour du pivot 11a et elle est solidaire d'une plaque 11c qui, en tournant lorsqu'elle est dégagée de la tige 12 du levier 12a réactionné par le ressort 12b, provoque par l'intermédiaire de la petite tige 11e et de la biellette 11d la rotation du pivot de sécurité SRA3 autour du petit arbre 11f garantissant encore la sécurité de l'accrochage entre les semi-remorques.In fig. 6 is illustrated the anti-nesting bar A1 and the bar 11 which allows its rotation; this bar rotates around the pivot 11a and it is integral with a plate 11c which, when rotating when it is released from the rod 12 of the lever 12a reacted by the spring 12b, causes by means of the small rod 11e and the link 11d the rotation of the safety pivot SRA3 around the small shaft 11f still guaranteeing the safety of the coupling between the semi-trailers.

Les châssis qui constituent les interfaces des wagons bou­cliers peuvent tourner autour du pivot R3 de la crapaudine de manière à permettre le couplage de chaque wagon bouclier au semi-remorque, par n'importe laquelle de ses deux extrémi­tés.The chassis which constitute the interfaces of the shield wagons can rotate around the pivot R3 of the crapaudine so as to allow the coupling of each shield wagon to the semi-trailer, by either of its two ends.

L'installation pneumatique qui permet le soulèvement de la partie postérieure du semi-remorque grâce aux suspensions du boggie routier comprend une fin de course 17 actionnée par la barre anti-emboîtement A1 quand elle pivote vers le haut pour permettre la circulation sur rails. Cette fin de course, par l'intermédiaire des valves 19, provoque le soulèvement du semi-remorque au moyen du gonflage des cylindres SP des suspensions du boggie routier: l'air arrive à travers la valve 18 et la hauteur minimum de soulèvement est prédéterminée par le robinet de fin de course 21.The pneumatic installation which allows the lifting of the rear part of the semi-trailer thanks to the suspensions of the road bogie includes a limit switch 17 actuated by the anti-interlocking bar A1 when it pivots upwards to allow movement on rails. This limit switch, via the valves 19, causes the semi-trailer to be raised by means of the inflation of the cylinders SP of the suspensions of the road bogie: the air arrives through the valve 18 and the minimum height of lifting is predetermined. by the limit stop valve 21.

La nécéssité de soulever l'extrémité du semi-remorque dans la manoeuvre de couplage du boggie ferroviaire CF, à une hauteur supérieure à celle du semi-remorque quand il circule sur route, dérive du fait que si le boggie routier est inamovible et doit voyager sur rails, il doit être soulevé d'environ 25 cm. de la surface des rails, soulèvement qu'il est difficile d'accomplir uniquement avec les cylindres de soulèvement CSA reliés en même temps au semi-remorque et aux essieux du boggie routier.The need to lift the end of the semi-trailer in the coupling maneuver of the CF rail bogie, to a height greater than that of the semi-trailer when it is traveling on the road, derives from the fact that if the road bogie is immovable and must travel on rails, it should be lifted about 25 cm. from the surface of the rails, lifting which is difficult to accomplish only with the CSA lifting cylinders connected at the same time to the semi-trailer and to the axles of the road bogie.

Une fois atteinte la position de soulèvement maximum du châssis et une fois que le boggie ferroviaire est inséré, la fin de course 16 actionnée par le verrou du crochet qui bloque l'interface 1 du boggie ferroviaire avec le semi-remorque actionne la valve 18 en déviant l'air qui, en état de repos, alimentait les cylindres SP des suspensions pneumatiques des roues du boggie routier, dans les cylindres CSA qui doivent soulever les essieux des roues, à l'intérieur du gabarit ferroviaire limite.Once the maximum lifting position of the chassis is reached and once the railway bogie is inserted, the limit switch 16 actuated by the hook lock which blocks the interface 1 of the railway bogie with the semi-trailer actuates the valve 18 in deflecting the air which, in a state of rest, supplied the cylinders SP of the pneumatic suspensions of the wheels of the road bogie, in the cylinders CSA who must lift the wheel axles, inside the limit railway gauge.

Une fois que l'on a atteint la position de soulèvement maximum des essieux, on insère des crochets de sécurité auxquels on associe une fin de course 20 qui empêche, au cas où soit désinséré le verrou 1b au cours d'une manoeuvre accidentelle de la poignée 1e, que la valve 18 alimente les cylindres SP des suspensions à travers les valves 19, quand les essieux du boggie routier sont soulevés et ainsi maintenus par le dispositif d'accrochage mécanique, en provocant la rupture.Once the maximum axle lifting position has been reached, safety hooks are inserted with which a limit switch 20 is associated which prevents, in the event that the latch 1b is removed during an accidental operation of the handle 1e, that the valve 18 feeds the cylinders SP of the suspensions through the valves 19, when the axles of the road bogie are lifted and thus held by the mechanical latching device, causing rupture.

Pour permettre au semi-remorque de circuler, les essieux du boggie routier doivent être décrochés des crochets de sécurités par une manoeuvre effectuée à la main et l'on doit extraire le verrou 1b.To allow the semi-trailer to circulate, the axles of the road bogie must be unhooked from the safety hooks by an operation carried out by hand and the lock 1b must be extracted.

Ces manoeuvres provoquent en effet, au même moment, le gonflage des cylindres des suspensions SP et le dégonflage des cylindres CSA à travers la valve 18 revenue dans la position de repos; successivement, avec l'abaissement de la barre anti-emboîtement, la valve niveleuse 22 est réacti­vée, provoquant le juste gonflage des cylindres SP.These maneuvers cause, at the same time, the inflation of the cylinders of the suspensions SP and the deflation of the cylinders CSA through the valve 18 returned to the rest position; successively, with the lowering of the anti-nesting bar, the leveling valve 22 is reactivated, causing the correct inflation of the cylinders SP.

Sur le schéma de la fig.14 sont illustrés les dispositifs qui provoquent les interventions de l'installation de frei­nage des semi-remorques par abaissement de la pression de l'air.The diagram in fig. 14 shows the devices which cause the braking system of semi-trailers to intervene by lowering the air pressure.

Le freinage peut être provoqué par la rupture du boyau 24 par le couteau 25 ou par le désenclenchement des crochets de sécurité mécanique qui entraîne l'ouverture du robinet 20a ou par la manoeuvre de la poignée 1e du verrou 1b.Braking can be caused by the rupture of the hose 24 by the knife 25 or by the disengagement of the mechanical safety hooks which causes the valve 20a to open or by the operation of the handle 1e of the lock 1b.
